2. Description of the Related Art Alzheimer's disease (AD) is a progressive degenerative disease of the brain primarily associated with aging. Clinical ation of AD is characterized by loss of memory, cognition, reasoning, judgment, and orientation. As the disease progresses, motor, sensory, and linguistic abilities are also affected until there is global impairment of multiple cognitive functions. These cognitive losses occur gradually, but typically lead to severe impairment and eventual death in the range of four to twelve years.

Alzheimer's disease is characterized by two major pathologic observations in the brain: neurofibrillary tangles and beta amyloid (or neuritic) plaques, comprised predominantly of an aggregate of a peptide fragment know as A beta.

Individuals with AD exhibit characteristic beta-amyloid deposits in the brain (. beta amyloid'plaques) and in cerebral blood vessels (beta amyloid angiopathy) as well as neurofibrillary tangles. Neurofibrillary tangles occur not only in Alzheimer's disease but also in other dementia-inducing disorders. On autopsy, large numbers of these lesions are generally found in areas of the human brain important for memory and cognition.

Smaller numbers of these lesions in a more restricted anatomical distribution are found in the brains of most aged humans who do not have clinical AD. Amyloidogenic plaques and vascular amyloid angiopathy also characterize the brains of individuals with Trisomy 21 (Down's Syndrome), Hereditary

Cerebral Hemorrhage with Amyloidosis of the Dutch-Type (HCHWA- D), and other neurogenerative disorders. Beta-amyloid is a defining feature of AD, now believed to be a causative precursor or factor in the development of the disease.

Deposition of A beta in areas of the brain responsible for cognitive activities is a major factor in the development of AD. Beta-amyloid plaques are predominantly composed of amyloid beta peptide (A beta, also sometimes designated betaA4). A beta peptide is derived by proteolysis of the amyloid precursor protein (APP) and is comprised of 39-42 amino acids. Several proteases called secretases are involved in the processing of APP.

Cleavage of APP at the N-terminus of the A beta peptide by beta-secretase and at the C-terminus by one or more gamma- secretases constitutes the beta-amyloidogenic pathway, i. e. the pathway by which A beta is formed. Cleavage of APP by alpha- secretase produces alpha-sAPP, a secreted form of APP that does not result in beta-amyloid plaque formation. This alternate pathway precludes the formation of A beta peptide.

An aspartyl protease has been identified as the enzyme responsible for processing of APP at the beta-secretase cleavage site. The beta-secretase enzyme has been disclosed using varied nomenclature, including BACE, Asp, and Memapsin.

Several lines of evidence indicate that progressive cerebral deposition of beta-amyloid peptide (A beta) plays a seminal role in the pathogenesis of AD and can precede cognitive symptoms by years or decades. Release of A beta from neuronal cells grown in culture and the presence of A beta in cerebrospinal fluid (CSF) of both normal individuals and AD patients has been demonstrated.

It has been proposed that A beta peptide accumulates as a result of APP processing by beta secretase, thus inhibition of this enzyme's activity is desirable for the treatement of AD.

In vivo processing of APP at the beta-secretase cleavage site

is thought to be a rate-limiting step in A beta production, and is thus a therapeutic target for the treatment of AD.

BACE1 knockout mice fail to produce A beta, and a normal phenotype. When crossed with transgenic mice that overexpress APP, the progeny show reduced amounts of A beta in brain extracts as compared with control animals (Luo et. al. , 2001 Nature Neuroscience 4: 231-232). This evidence further supports the proposal that inhibition of beta-secretase activity and reduction of A beta in the brain provides a therapeutic method for the treatment of AD and other beta amyloid disorders.

At present there are no effective treatments for halting, preventing, or reversing the progression of Alzheimer's disease. Therefore, there is an urgent need for pharmaceutical agents capable of slowing the progression of Alzheimer's disease and/or preventing it in the first place.

Compounds that are effective inhibitors of beta-secretase, that inhibit beta-secretase-mediated cleavage of APP, that are effective inhibitors of A beta production, and/or are effective to reduce amyloid beta deposits or plaques, are needed for the treatment and prevention of disease characterized by amyloid beta deposits or plaques, such as AD.

The compounds of the invention inhibit beta-secretase and are therefor useful in treating and preventing Alzheimer's disease. The compounds of the invention are made by methods well known to those skilled in the art from starting compounds known to those skilled in the art. The process chemistry is well known to those skilled in the art. The most general process to prepare compounds of the invention is set forth in CHART A. Typically, amino acid (I) is protected at the amino

group, yielding protected amino acid (II). Compound (II) is converted to an ester intermediate, and the intermediate is reacted with a carbon nucleofile yielding compound (III). The ketone moiety in compound (III) is reduced to yield alcohol (IV), which forms epoxide (V). The addition of amine RC-NH2 (VI) opens the epoxide, forming the protected alcohol (VII). The amine protecting group is removed, and the deprotected amine (VIII) is reacted with an amide forming agent of the formula (RN-1-XN) 2O or R N-1-XN-X2 or R N-1-XN-OH (IX) to produce a target compound of formula (X).

The backbone of the compounds of the invention is a hydroxyethylamine moiety, -NH-CH (R) -CH (OH) -. It can be readily prepared by methods disclosed in the literature and known to those skilled in the art. For example, J. Med. Chem. , 36,288-291 (1992), Tetrahedron Letters, 28, 5569-5572 (1987), J. Med. Chem. , 38,581-584 (1994) and Tetrahedron Letters, 38, 619-620 (1997) all disclose processes to prepare hydroxyethylamine type compounds.

CHART A sets forth a general method used in the invention to prepare the appropriately substituted amines (X). The compounds of the invention are prepared by starting with the corresponding amino acid (I). The amino acids (I) are well known to those skilled in the art or can be readily prepared from known compounds by methods well known to those skilled in the art. The substituted amines (X) of the invention have at least two enantiomeric centers which give four enantiomers.

The first of these enantiomeric centers derives from the amino acid starting material (I). It is preferred to commercially obtain or produce the desired enantiomer (S) rather than produce an enantiomerically impure mixture and then have to separate out the desired enantiomer (S). It is preferred to start the process with enantiomerically pure (S) -amino acid (I)

of the same configuration as that of the substituted amine (X) product.

The first step of the process is to protect the free amino group of the (S) -amino acid (I) with an amino protecting group to produce the (S) -protected amino acid (II) by methods well known to those skilled in the art. Amino protecting groups are well known to those skilled in the art. See for example, "Protecting Groups in Organic Synthesis", John Wiley and sons, New York, N. Y. , 1981, Chapter 7;"Protecting Groups in Organic Chemistry", Plenum Press, New York, N. Y. , 1973, Chapter 2. The function of the amino protecting group is to protect the free amino functionality (-NH2) during subsequent reactions on the (S) -amino acid (I) which would not proceed well, either because the amino group would react and be functionalized in a way that is inconsistent with its need to be free for subsequent reactions, or the free amino group would interfere in the reaction. When the amino protecting group is no longer needed, it is removed by methods well known to those skilled in the art. By definition the amino protecting group must be readily removable as is known to those skilled in the art by methods well known to those skilled in the art. Suitable amino PROTECTING GROUP is selected from the group consisting of t- butoxycarbonyl, benzyloxycarbonyl, formyl, trityl, acetyl, trichloroacetyl, dichloroacetyl, chloroacetyl, trifluoroacetyl, difluoroacetyl, fluoroacetyl, 4-phenylbenzyloxycarbonyl, 2- methylbenzyloxycarbonyl, 4-ethoxybenzyloxycarbonyl, 4- fluorobenzyloxycarbonyl, 4-chlorobenzyloxycarbonyl, 3- chlorobenzyloxycarbonyl, 2-chlorobenzyloxycarbonyl, 2,4- dichlorobenzyloxycarbonyl, 4-bromobenzyloxycarbonyl, 3- bromobenzyloxycarbonyl, 4-nitrobenzyloxycarbonyl, 4- cyanobenzyloxycarbonyl, 2- (4-xenyl) isopropoxycarbonyl, 1,1- diphenyleth-1-yloxycarbonyl, 1, 1-diphenylprop-1-yloxycarbonyl, 2-phenylprop-2-yloxycarbonyl, 2- (p-toluyl) prop-2-yloxycarbonyl, cyclopentanyloxycarbonyl, 1-methylcyclopentanyloxycarbonyl,

cyclohexanyloxycarbonyl, 1-methylcyclohexanyloxycabonyl, 2- <BR> <BR> <BR> <BR> methylcyclohexanyloxycarbonyl, 2- (4- toluylsulfonyl) ethoxycarbonyl, 2- (methylsulfonyl) ethoxycarbonyl, 2- (triphenylphosphino) ethoxycarbonyl, fluorenylmethoxycarbonyl, 2- (trimethylsilyl) ethoxycarbonyl, allyloxycarbonyl, 1- (trimethylsilylmethyl) prop-1-enyloxycarbonyl, 5- benzisoxalylmethoxycarbonyl, 4-acetoxybenzyloxycarbonyl, 2,2, 2- trichloroethoxycarbonyl, 2-ethynyl-2-propoxycarbonyl, cyclopropylmethoxycarbonyl, 4- (decyloxyl) benzyloxycarbonyl, isobornyloxycarbonyl and 1-piperidyloxycarbonyl, 9- fluorenylmethyl carbonate, - CH-CH=CH2 and phenyl-C (=N-) -H. It is preferred that the protecting group be t-butoxycarbonyl (BOC) and benzyloxycarbonyl (CBZ), it is more preferred that the protecting group be t-butoxycarbonyl. One skilled in the art will understand the preferred methods of introducing a t- butoxycarbonyl or benzyloxycarbonyl protecting group and may additionally consult T. W. Green and P. G. M. Wuts in"Protective Groups in Organic Chemistry, "John Wiley and Sons, 1991 for guidance.

The (S) -protected compound (II) is transformed to a (S)- protected compound of formula (III) by first converting the (S) -protected amino acid (II) to a corresponding alkyl ester according to methods well established in the art, for example by reaction with a diazocompound. The ester inermediate is then reacted with a carbanionic nucleofile of those known to those skilled in the art, for example an organometallic compound obtained by reacting a compound of formula X1-C (R2) (R3)-Xl with a strong metal base, wherein wherein the reaction yields a halogen-metal exchange, and wherein-X1 is a halogen selected from the group consisting of chlorine, bromine or iodine. The addition of this carbanionic nucleophile to the ester intermediate yields the (S) -protected compound (III).

Suitable bases include, but are not limited to the alkyllithiums including, for example, sec-butyllithium, n- butyllithium, and t-butyllithium. Said reactions are preferably conducted at low temperature, for example-78 degrees C. Suitable reaction conditions include running the reaction in the presence of inert solvents or mixtures thereof, for example but not only ether, tetrahydrofuran or a mixture thereof. Wherein R2 and R3 are both hydrogen, then examples of Xi-C (R2) (R3)-Xl include dibromomethane, diiodomethane, chloroiodomethane, bromoiodomethane and bromochloromethane.

One skilled in the art knows the preferred conditions required to conduct this reaction. Furthermore, if R2 and/or R3 are not - H, then by the addition of-C (R2) (R3)-X1 to esters of the (S)- protected amino acid (II) to produce the (S)-protected compound (III), an additional chiral center will be incorporated into the product, provided that R2 and R3 are not the same.

The (S)-protected compound (III) is then reduced by methods known to those skilled in the art for the reduction of ketones to the corresponding alcohol (IV). The reactants and reaction conditions for reducing the (S)-protected compound (III) to the corresponding alcohol (IV) include, for example, sodium borohydride, lithium borohydride, borane, diisobutylaluminum hydride, and lithium aluminium hydride.

Sodium borohydride is the preferred reducing agent. The reduction is carried out for a period of time between 1 hour and 3 days at temperatures ranging from about-78 degrees C to the reflux temperature of the reaction mixture. It is preferred to conduct the reduction between about-78 degrees C and about 0 degrees C. A borane complex may be used, for example, borane-methyl sulfide complex, borane-piperidine complex, or borane-tetrahydrofuran complex. The preferred combination of reducing agents and reaction conditions needed are known to those skilled in the art, see for example, Larock, R. C. in Comprehensive Organic Transformations, VCH Publishers,

1989. The reduction of the (S) -protected compound (III) to the corresponding alcohol (IV) produces the second chiral center (third chiral center if R2 and R3 are not the same). The reduction of the (S) -protected compound (III) produces a mixture of enantiomers at the second center, (S, R/S)-alcohol (IV). This enantiomeric mixture is then separated by means known to those skilled in the art such as selective low- temperature recrystallization or chromatographic separation, for example by HPLC, employing commercially available chiral stationary phases. The enantiomer that is used in the remainder of the process of CHART A is the (S, S) -alcohol (IV) since this enantiomer is a precursor to the desired biologically active anti-Alzheimer (S, R) -substituted amine (X).

(S, S) -alcohol (IV) reacts intramolecularly to yield the corresponding epoxide (V) by means known to those skilled in the art. The stereochemistry of the (carbon bound to the-OH moiety in compound (IV) is maintained in the epoxide (V).

Preferred reaction conditions include contacting compound (IV) with a base, for example, but not limited to, sodium hydroxide, potassium hydroxide, or lithium hydroxide. Reaction conditions include the presence of a C1-C6 alcohol solvent; ethanol is preferred. A common co-solvent, for example ethyl acetate, may also be employed. The reactions is preferably conducted at temperatures ranging from about-45 degrees C to the reflux temperature of the reaction mixture; preferred temperature ranges are between about-20 degrees C and about 20-25 degrees C.

The epoxide (V) is then reacted with the appropriately substituted C-terminal amine, Rc-NH2 (VI) in reaction conditions known to those skilled in the art, leading to the opening the epoxide to yield the enantiomerically pure (S, R)- protected alcohol (VII). The substituted C-terminal amines, Rc-NH2 (VI) of this invention are commercially available or are known to those skilled in the art and can be readily prepared

from known compounds. Further, it is preferred that when Rc is phenyl, it is substituted in the 3-position or 3,5-positions.

Suitable reaction conditions for opening the epoxide (V) include running the reaction in an organic, preferably inert w.

C1-C6 alcohol solvents are preferred and isopropyl alcohol most preferred. The reaction can be run at temperatures ranging from about 20-25 degrees C up to the reflux temperature of the reaction mixture and preferably at a temperature between about 50 degrees C and the reflux temperature of the reaction mixture. When the substituted C-terminal amine (VI) is a 1- amino-3,5-cis-dimethyl cyclohexyldicarboxylate it is preferrably prepared as follows. To dimethyl-5- aminoisophthalate in acetic acid and methanol, is added rhodium in alumina in a high-pressure bottle. The bottle is saturated with hydrogen at 55 psi and shaken for one week of time. The mixture is then filtered through a layer of diatomaceous earth and rinsed with methanol three times, the solvents are removed under reduced pressure (with heat) to give a concentrate. The concentrate is triturated with ether and filtered again to give the desired C-terminal amine (VI). When the substituted C- terminal amine (VI) is 1-amino-3, 5-cis-dimethoxy cyclohexane it is prepared by following the general procedure above and making non-critical variations but starting wth 3,5-dimethoxyaniline.

When the substituted C-terminal amine (VI) is an aminomethyl group where the substituent on the methyl group is an aryl group, for example NH2-CH2-Rcaryl/and NH2-CH2-Rcaryl is not commercially available it is preferrably prepared as follows.

A suitable starting material is the (appropriately substituted) aralkyl compound. The first step is bromination of the alkyl substitutent via methods known to those skilled in the art, see for example R. C. Larock in Comprehensive Organic Transformations, VCH Publishers, 1989, p. 313. Next the alkyl halide is reacted with azide to produce the aryl- (alkyl)-azide.

Last the azide is reduced to the corresponding amine by

hydrogen/catalyst to give the C-terminal amine (VI) of formula NH2-CH2-Rc-aryl-The suitably functionalized C-terminal amines (VI) may readily be prepared by one skilled in the art via known methods in the literature, making non-significant modifications.

CHART B discloses an alternative process for the synthesis of the enantiomerically pure (S, R)-protected alcohol (VII) from the (S)-protected compound (III). In this process, (S)- protected compound (III) is reacted with the appropriately substituted C-terminal amine Rc-NH2 (VI) in the preferred reaction conditions described above to yield (S)-protected ketone (XI) which is reduced in the preferred conditions described above to yield (S, R) -protected alcohol (VII).

CHART C discloses another alternative process for the synthesis of enantiomerically pure (S, R) -protected alcohol (VII) from the epoxide (V). Epoxide (V) is reacted with azide, yielding the enantiomerically pure (S, R) -protected azide (XII) in reaction conditions known to those skilled in the art,, for example, J. March, Advanced Organic Chemistry, 3rd Edition, John Wiley & Sons Publishers, 1985, p. 380. (S, R)-protected azide (XII) is reduced to protected amine (XIII) by methods known to those skilled in the art for the reduction of an azide group in the presence of a t-butoxycarbonyl N-protecting group, for example catalytic hydrogenation.. Alternative reducing conditions which may be used to avoid N-deprotection with protecting groups other than t-butoxycarbonyl are known to those skilled in the art, see for example, R. C. Larock in

Comprehensive Organic Transformations, VCH Publishers, 1989, p.

409.

The (S, R) -protected compound (XIII) ) is deprotected to yield (S, R) -amine (VII) by methods known to those skilled in the art for removal of amine protecting group. Suitable reaction conditions for the removal of an amine protecting group depend on the type of protecting group. For example, it is preferable to remove the preferred protecting group, BOC, by contacting (S, R) -protected alcohol (VII) with a mixture of and acid and an organic solvent, e. g. a trifluoroacetic acid/dichloromethane mixture, yielding the protonated salt of (S, R)-amine (VII). Optionally, (S, R) -amine (VII) can be purified by methods known to those skilled in the art, for example recrystallization. The free-base (S, R) -amine (VII) can be obtained by means known to those skilled in the art, such as for example, preparing the free base amine by contacting the salt with mild basic conditions. Additional BOC deprotection conditions and deprotection conditions for other protecting groups can be found in T. W. Green and P. G. M.

Wuts in"Protective Groups in Organic Chemistry, "John Wiley and Sons, 1991, p. 309. Typical chemically suitable salts include trifluoroacetate, chloride, sulfate, phosphate; preferred is trifluoroacetate and chloride.

(S, R) -amine (VIII) is reacted with an appropriately substituted acylating reagent (IX) such as an anhydride, acyl halide, or acid of the formula (RN-1-XN) 2o or RN-1-XN-X2 or RN_ 1-XN-OH (IX) in reaction conditions known to those skilled in the art to produce (S, R) -substituted amine (X). Reaction conditions known to those skilled in the art can be found, for example, in R. C. Larock in Comprehensive Organic Transformations, VCH Publishers, 1989, p. 981,979, and 972.

RN is preferably selected from the group consisting of: RN1-XN-wherein XN is-CO-, RN-1 is RN-aryl or RN-heteroaryl wherein RN-aryl is phenyl where the substitution on phenyl is

1,3-, and wherein RN-aryl or RN-heteroaryl are substituted with one- CO-NRN-2RN-3, wherein XN is-CO-, RN-1 is RX-aryl or RN-heteroaryl wherein RN_aryl is phenyl substituted with one C1 alkyl wherein the substitution on the phenyl is 1,3, 5-, and wherein RN-aryl or RN-heteroaryi are substituted with one -CO-NRN-2-RN-3, RN-@-XN- wherein XN is-CO-, and RN-1 is RN-heteroaryl wherein RN-heteroaryl is substituted with one-CO-NRN-2RN-3. RN-2 and RN-3 are preferably the same and are C3 alkyl, RN-1-XN, wherein XN is-CO-, and RN_1 is RN-aryl wherein RN-aryl is phenyl substituted with one-CO-NRN-2RN-3 wherein the substitution on phenyl is 1,3-, RN-1-XN- wherein XN is-CO-, and RN-1 is RN-aryl wherein RN-aryl is phenyl substituted with one C1 alkyl and with one-CO-NRN-2RN- 3 wherein the substitution on the phenyl is 1,3, 5-. XN is preferably (A)-CO-and (B)-S02- ; more preferably XN is-CO-.

X2 is selected from the group consisting of-Cl,-Br ; more preferably, X2 is-Cl.

Acylating reagents, (RN-1-XN) 2O or R N-1-XN-X2 or R N-1- XN-OH (IX) are known to those skilled in the art and are commercially available or can be readily prepared from known starting materials by methods disclosed in the literature.

Isophthalic acid derivatives (IX) of the formula RN2RN_3N-CO- phenyl-CO-or methylisophthalic acid derivatives (IX) of the formula RN-2RN-3N-CO- (CH3-) phenyl-CO- where the substitution is 5-methyl- 1,3-isophthalic acid are the preferred acylating reagents. The most preferred 5-methyl-1, 3-isophthalic acid derivative is 3- [ (N, N-dipropylamino) carbonyl] -5-methylbenzoic acid (IX). These compounds are preferably synthesized according to the following method. An ester, preferably the monomethyl ester of isophthalic acid or methyl 5-methyl-1, 3-isophthalate is dissolved in an orgonanic solvent or a mixture of solvents, preferably a THF/DMF mixture. 1, 1' -Carbonyldiimidazole is

added at a temperature of about 20-25 degrees C. A preferred amine (H-NRN2RN_3) is added. Following from about 1 hr to about 24 hrs of stirring at a temperature from about 20 degrees C to the reflux temperature of the reaction mixture, the reaction mixture is partitioned between saturated aqueous ammonium chloride and a water immiscible organic solvent, for example ethyl acetate. The aqueous layer is separated and extracted twice more with the organic solvent. The organic extracts are combined and washed with a saturated aqueous solutions of bicarbonate and saline and dried over anhydrous sodium sulfate or magnesium sulfate. Filtration of the drying agent and removal of solvents by reduced pressure yields the methyl ester of the desired RN_2RN_3N-CO-phenyl-CO-O-CH3 or a methylisophthalic acid acylating agent (IX) RN2RN3N-CO-(CH3- ) phenyl-CO-0-CH3. Purification of the (methyl) ester can be carried out for example via chromatography on silica gel eluting with a mixture of ethyl acetate and hexanes as mobile phase. The isophthalate ester or methylisophthalate ester of the mono-alkyl or di-alkyl amide iscontacted with an aqueous alkaline solution, for example lithium hydroxide in a minimum amount of THF/methanol/water and stirred 3-24 hours at 20 degrees C to the reflux temperature of the reaction mixture.

The solvents are then removed under reduced pressure and the products partitioned between water and a water immiscible solvent, for example ethyl acetate. If the formation of an emulsion hinders the separation of the two phases, a small amount of saline is added to aid the separation. The aqueous phase is extracted once more with a water immiscible solvent, for example ethyl acetate. The aqueous phase is then acidified via the addition of an acid, preferably hydrochloric acid, to pH < 3. The resulting mixture is extracted three times with a water immiscible solvent, for example ethyl acetate. The combined organic extracts are dried over anhydrous sodium or magnesium sulfate. The drying agent is removed by filtration

and the organic solvent is removed under reduced pressure to yield the product. The mono-or di-alkyl amide isophthalate/methylisophthalate is reacted with (S, R)-amine (VIII) to produce the (S, R) -substituted amine (X).

If RN-2 and RN-3 are both-H, the following method is preferred. An ester, preferably the methyl ester of isophthalate or methyl 5-methyl-1, 3-isophthalate is dissolved in an organic solvent or a mixture of organic solvents, preferably a THF/DMF mixture. CDI is added at about 20-25 degrees C. After five to thirty minutes, ammonia gas is bubbled into the mixture for 1 hr. The mixture is cooled to about 0 degrees C for the duration of the ammonia bubbling. The reaction mixture is left stirring under a balloon of ammonia overnight at about 20-25 degrees C, and partitioned between saturated aqueous ammonium chloride and a water immiscible solvent, for example ethyl acetate. The phases are separated and the aqueous phase is twice extracted with ethyl acetate.

The organic extracts are washed with saturated aqueous solutions of bicarbonate and saline and dried over anhydrous sodium or magnesium sulfate. Filtration of the drying agent and removal of solvents under reduced pressure yields the ester of the desired isophthalic acid or the isophthalic acid derivative acylating reagent (IX). Purification of the (methyl) ester can be carried by example via chromatography on silica gel with an isopropanol/chloroform eluting mixture.

The isophthalate ester or methylisophthalate ester of the primary amide is contacted with an aqueous alkaline solution such as lithium hydroxide in THF/methanol/water and stirred overnight at about 20-25 degrees C after which time the solvents are removed under reduced pressure and the solids are partitioned between water and a water immiscible solvent, for example ethyl acetate. If the formation of an emulsions hinders separation of the two phases, a small amount of saline solution is added to improve separation. The aqueous phase is

separated and extracted with a water immiscible solvent, for example ethyl acetate. The aqueous phase is then acidified with acid, preferably hydrochloric acid, to pH < 3. The resulting mixture is extracted with ethyl acetate. The combined organic extracts are dried over anhydrous sodium or magnesium sulfate. The drying agent is removed by filtration and the organic solvent removed under reduced pressure to yield the product. The amide isophthalic acid derivative is reacted with (VIII) to produce (X).

When it is preferred that the amine moiety be part of cyclic group, for example morpholinyl, piperazinyl, piperidinyl and pyrrolidinyl, etc the following method is preferably used. An ester, preferably the methyl ester of isophthalic acid or methyl 5-methyl-1, 3-isophthalate is dissolved in an anhydrous solvent, for example methylene chloride, and a small quantity of a dipolar aprotic solvent, for example DMF is added. The mixture is cooled to about 0 degrees C and oxalyl chloride is added. The mixture is stirred at about 0 degrees C for about 30 minutes to about two hours after which the solvents are removed under reduced pressure.

The crude acid chloride solid is left under vacuum overnight, and dissolved in dry methylene and cooled to about 0 degrees C prior to the addition of a cyclic amine and a tertiary amine base, for example N-methyl piperidine. The reaction mixture is stirred at about 0 degrees C for about 1 to about 6 hrs before the solvents are removed under reduced pressure. The residue is diluted with water and a water immiscible solvent, for example ethyl acetate, for example, and the phases are separated. The aqueous phase is extracted with a water immiscible solvent, for example ethyl acetate, , and the combined organic extracts are washed with saturated aqueous bicarbonate and dried over anhydrous sodium or magnesium sulfate. Filtration of the drying agent and removal of solvents under reduced pressure yields the product cyclic

amide. The cyclic amide is contacted with an aqueous alkaline solution, for example lithium hydroxide in THF/methanol/water and stirred overnight at about 20-25 degrees C, after which time the solvents are removed under reduced pressure and the residue is partitioned between water and a water immiscible solvent, for example ethyl acetate. The aqueous phase is extracted with ethyl acetate. Removal of water from the aqueous phase under reduced pressure yields the target cyclic amide product (IX).

When the RN1 moiety in the target product is a carbocycle, for example but not limited to, cyclohexane, with the starting reagent may be a suitably functionalized dimethyl isophthalate and the method one of those taught in the literature (Meyers, A. I., Org. Syn., 1971,51, 103) one may reduce the six-membered ring with reducing agents such as rhodium (5%) on alumina in the presence of acetic acid and methanol under a hydrogen atmosphere to afford the corresponding dimethyl cyclohexane dicarboxylate.

CHART D sets forth an alternative process for production of the (S, R) -substituted amine (X) from the (S, R)-protected azide (XII), which is produced from the corresponding epoxide (V) in CHART C. The amino protecting group is removed to produce the corresponding unprotected azide (XIV) by methods previously described in CHART A for the conversion of (S, R)- protected alcohol (VII) to the corresponding (S, R)-amine (VIII). The (S, R) -unprotected azide (XIV) is then acylated on nitrogen to produce the corresponding (S, R)-azide (XV). Next, the azide functionality is reduced as previously discussed for the conversion of the (S, R) -protected azide (XII) to the corresponding (S, R) -protected amine (XIII) to give the (S, R)- free amine (XVI). Last, the (S, R) -free amine (XVI) is transformed to the corresponding (S, R) -substituted amine (X) by nitrogen alkylation with a compound of the formula RC-X3 to give the corresponding (S, R) -substituted amine (X). X3 is an

appropriate leaving group, such as but not limited to,-Cl,- Br,-I,-0-mesylate,-0-tosylate, 0-triflate, etc. X3 may also be an aldehyde; the corresponding coupling with (XVI) via the well known reductive amination procedure gives the (S, R)- substituted amine (X).

Carbocylic amide forming agents (IX) are also provided for by the invention. For example, the carbocyclic amide forming agents of the formula |---------------------| R'-CH-C(R'')(R''')-CH-XN-OH (IX) are readily prepared from known starting materials by methods disclosed in the literature and known to those skilled in the art, for example, J. Med.

Chem. 1998, 41, 1581, J. Org. Chem. 2000, 65, 1305. It is also understood that instead of the carboxylic acid, one may readily employ an acyl halide, where the halide is preferably choride, or a suitable group to produce a mixed anhydride; these methods are taught by CHART A. For additional guidance on the formation of carbocyles and preferably cyclopropanes, one may consult M. P. Doyle; M. A. McKervery; T. Ye in Modern Catalytic Methods for Organic Synthesis with Diazo Compounds From Cyclopropanes to Ylides, Wiley-Interscience, 1998, pp. 163-279.

CHARTs E, F, G, and H disclose various methods to produce the RN portion of the substituted amine (X) where the phenyl ring of the RN 1,3-disubstituted moiety, - CO-phenyl-CO-, is further substituted in the 5-position with various groups such as amides, nitriles, halides, and amines.

These compounds are prepared by methods known to those skilled in the art. The process chemistry of each reaction is known to those skilled in the art. The novelty here is represented by the order of each process step and/or the specific reactants used. One skilled in the art knowing the desired product would know at least one method to prepare the desired product by using known starting materials. Hence, the following

discussion is not necessary but is set forth to further aid those interested in preparing the compounds of the invention.

CHART E discloses alternate processes for the transformation of the aniline (XVII) or acid ester (XVIII) to the corresponding acid (IX-XXIII). One process begins with the commercially available aniline (XVII). The aniline (XVII) is treated with a diazotizing reagent such as sodium or potassium nitrite in mineral acid, followed by a halogen source such as copper (II) halide or alkali metal halide, or by an organic diazotizing reagent such as an alkyl nitrite in a strong acid such as acetic acid or trifluoroacetic acid, followed by a halide source such as copper (II) halide or alkali metal halide to give the halo acid ester (XIX).

Alternatively, the acid ester (XVIII) is treated with N- halosuccinimide and trifluoromethanesulfonic acid to give the halo acid ester (XIX). The halo acid ester (XIX) is then converted to the ester amide (XXI) using a primary or secondary amine of the formula H-NG1G2 where G1 and G2 are the same or different or can be cyclized. G1 and G2 become part of the substituted amine (X) and are included in the definition of RN.

RN includes RN1-XN-where the linker,-XN-, includes-CO-and RN-1 includes RN_aryl. RN-aryl is defined to include phenyl (- phenyl) optionally substituted with one or two amides: -CO-NRN2RN_3 and -CO-RN-4.

Alternatively, the halo acid ester (XIX) is converted to the acid chloride halo ester (XX) by methods known to those skilled in the art. One of skill in the art will appreciate that other acid halides may also be used. The dihalo ester (XX) is treated with a primary or secondary amine of the formula H-NG1G2 to give the ester amide (XXI). The ester amide (XXI) is then reacted with an AMINE in a carbon monoxide atmosphere in the presence of a palladium catalyst using methods such as those reviewed by Heck, (Palladium Reagents in

Organic Synthesis, 1985 pp. 342-365). to give the diamide (XXII). Hydrolysis of the ester portion of the diamide (XXII) using methods well known to those skilled in the art gives the diamide acid (XXIII).

In CHART F, an alternate route to intermediate diamide (XXII) is shown starting from commercially available phenol (XXIV). The phenol (XXIV) is treated with a trifluoromethanesulfonating reagent such as trifluoromethanesulfonic anhydride to give triflate (XXV). The triflate (XXV) is reacted under the conditions of palladium catalysis in the presence of carbon monoxide and an amine of the formula H-NRNalphaRNbeta (AMINE) as for the conversion of the ester amide (XXI) to the corresponding diamide (XXII) in CHART E to give the diester (XXVI). The diester (XXVI) is hydrolyzed using methods known to those skilled in the art to give the monoacid (XXVII). The monoacid (XXVII) is then converted to the diamide (XXII) using conditions such as for the conversion of the halo acid ester (XIX) to the ester amide (XXI) in CHART E.

CHART G discloses another route to prepare the ester amide (XXI). The reaction starts with commercially available nitro compound (XXVIII) which is condensed with an (AMINE) using coupling methods known to those skilled in the art to give the nitro amide (XXX). The nitro amide (XXX) can also be prepared by first treating the nitro compound (XXVIII) with reagents such as thionyl chloride, or DMF and oxalyl chloride, or other methods known to those skilled in the art to give the acyl chloride (XXIX), which upon treatment with the (AMINE) gives the nitro amide (XXX). Reduction of the nitro amide (XXX) using methods known to those skilled in the art (see, for example, Smith and March, Advanced Organic Chemistry, 5th ed. ) gives amide aniline (XXXI). The amide aniline (XXXI) is then treated with diazotizing reagents such as sodium or potassium nitrite in mineral acid, followed by a halogen source such as

copper (II) halide or alkali metal halide, or by an organic diazotizing reagent such as an alkyl nitrite in a strong acid such as acetic acid or trifluoroacetic acid, followed by a halide source such as copper (II) halide or alkali metal halide to give the ester amide (XXI).

CHART H discloses a process to prepare the diamide acid (IX-XXIII) from the ester amide (XXI), where one of the amides is unsubstituted and is-CO-NH2. This process starts from either the ester or the acid, for example the ester amide (XXI) is treated with copper (I) cyanide (CuCN) in N- methylpyrrolidinone or DMF, preferably N-methylpyrrolidinone, to give the nitrile (XXXII). The nitrile (XXXII) is converted to the primary amide (XXXIII) using urea-hydrogen peroxide complex (see Synth. Commun. (1993) 3149) or the methods of Synth. Commun. (1990) 1445, Synth. Commun. (1997) 3119, J. Org.

Chem. (1992) 2521, Tet. Lett. (1996) 6555, Ind. J. Chem. , Sect.

B, (1999) 974, Tet. Lett. (1995) 3469, Tet. Lett. (1998) 3005, or others. When the ester amide (XXI) is in the form of an ester, an additional hydrolysis step using lithium hydroxide, sodium hydroxide, potassium hydroxide, barium hydroxide, or other hydrolysis methods known to those skilled in the art is used to convert the diamide ester (XXXIII) to the diamide acid (IX-XXIII).

CHART I discloses an alternate synthetic route from the protected alcohol (VII) to the substituted amine (X) which uses a diprotected intermediate (XXXIV) wherein the nitrogen atom attached to the RC substitutent is protected. Using the process of CHART I, the mono protected alcohol (VII) is reacted with a new protecting group to form the orthogonally protected (XXXIV). This is a common strategy employed in traditional peptide chemistry by those skilled in the art, see M. Bodansky, Principles of Peptide Chemistry. When the mono protected alcohol (VII) is protected with CBZ one skilled in the art could react it with either (BOC) in methylene chloride or

similar organic solvent or FMOC-Cl in methylene chloride or similar organic solvent to prepare orthogonally protected (XXXIV). Then the CBZ group is removed by hydrogenation in the presence of a catalytic amount of palladium on carbon in an alcoholic solvent, such as methanol, or ethyl acetate, or with catalytic palladium on carbon in alcoholic solvents in the presence of ammonium formate as is known to those skilled in the art. This gives the RC-N protected (XXXV). Similarly, when the mono protected alcohol (VII) is protected as a BOC it can be reacted with CBZ-Cl under Schotten-Bauman conditions or CBZ-OSu in THF to prepare the reversed (XXXIV). Then the BOC group can be cleaved with hydrochloric acid (4 N) in methanol, ethanol or dioxane or with trifluoroacetic acid in methylene chloride or by other methods such as those described in The Peptides, Analysis, Synthesis, Biology, Vol. 3, Ed. E. Gross and J. Meienhofer (1981) to liberate the CBZ Rc-N protected (XXXV). This functional group manipulation gives various permutations in the sequence (VII) to (XXXIV) to (XXXV) as is apparent to one skilled in the art. When the appropriately Rc- N protected compound (XXXV) is reacted with the amide forming agent (IX), in acid form, under standard peptide coupling conditions, for example, EDC/HOBt in methylene chloride or DMF or a previously activated acid, (RN_) 2O gives the corresponding RN-substituted RC-N protected (XXXVI). Simple de-protection of the RN-substituted RC-N protected (XXXVI) then gives the desired substituted amine (X). Thus when the RN-substituted RC-N protected (XXXVI) is protected with BOC, treatment with hydrochloric acid (4N) in dioxane or the other reagents discussed above gives the substituted amine (X). When the RN- substituted RC-N protected (XXXVI) is protected with CBZ, treatment with hydrogen from 10-50 psi in alcoholic solvents, such as methanol with a catalytic amount of palladium on carbon will give, after work-up, the desired substituted amine (X).

Similarly when the RN-substituted RC-N protected (XXXVI) is

protected with FMOC, treatment with a secondary amine, preferably either piperidine (10 %) or diethylamine (10 %) in an inert solvent such as, for example, methylene chloride will give after work up the desired substituted amine (X).

CHART J discloses a process to prepare compounds where the phenyl ring of the RN substituent of-CO-phenyl-CO-is substituted with a sulfonamide group in the 5-position. The process starts with the halo amide ester (XXI, CHART E) which is reacted with sodium nitrite, sulfur dioxide, copper chloride (II) and acetic acid by the method disclosed in J. Med. Chem. , 42,3797 (1999) to prepare the sulfonyl chloride (XXXVII). The sulfonyl chloride (XXXVII) is then reacted with AMINE, as defined above, by methods known to those skilled in the art to produce the corresponding sulfonamide (XXXVIII). Last the sulfonamide (XXXVIII) is transformed to the corresponding sulfonamide acid (XXXIX) by methods known to those skilled in the art such as using lithium hydroxide, sodium hydroxide, potassium hydroxide, barium hydroxide, or other hydrolysis methods known to those skilled in the art.

CHART K discloses how to prepare the RN substituents where RN is RN_1-XN-, where XN is-CO-and RN-1 is RNaryl where RN-aryl is phenyl substituted with one alkyl group and one-CO-NRN-2RN-3 or - CO-RN_4. See the discussion above for CHART E regarding the amine, H-NRNalphaRNbeta (AMINE), used to form the amide RN substituents. The process starts with the halo amide ester (XXI) which is then reacted with an alkyl boronic acid having the desired alkyl group in the presence of a palladium catalyst such as Pd (PPh3) Cl2 using the general method described in J.

Med. Chem., 4288 (2000). The alkyl boronic acids are commercially available or can be prepared by the process described in J. Am. Chem. Soc., 60,105 (1938). It is preferred that RN-b is bromo. This step produces the alkyl ester (XL) which is then hydrolyzed by means known to those skilled in the art to produce the desired alkyl acid (XLI).

CHART L discloses a process to prepare the amide forming agent (IX-XLVII) where the RN substituent is RN 1-XN-, where the linker,-XN-is-CO-, where RN-1 is RN_aryl and where RN-aryl is phenyl (-phenyl) substituted with groups: Ci-Ce alkyl, optionally substituted with one, two or three substituents selected from the group consisting of C1-C3 alkyl, <BR> <BR> <BR> <BR> -F,-Cl,-Br,-I,-OH,-SH,-C=N,-CF3, C1-C3 alkoxy,-NR1_aR1b where Ra and Ri-b are as defined above, and-N (-H and C1-C3 alkyl)-CO-RN5. This specific amide forming agent, (IX-XLVII) is prepared by starting with the phenyl nitro compoud (XLII) which is reduced to the corresponding phenyl nitro hydroxy compound (XLIII) using borane-methyl sulfide or borane in THF.

The phenyl nitro hydroxy compound (XLIII) is reduced to the corresponding phenyl amino hydroxy compound (XLIV) using hydrogen and palladium catalyst as is known to those skilled in the art. The phenyl amino hydroxy compound (XLIV) is reacted with an aldehyde in the presence of a reducing agent such as sodium cyanoborohydride or sodium triacetoxyborohydride to give the phenyl substituted amino hydroxy compound (XLV). The phenyl substituted amino hydroxy compound (XLV) is acylated with an acid chloride or acid anhydride by methods known to those skilled in the art to give the phenyl disubstituted amino hydroxy compound (XLVI). The phenyl disubstituted amino hydroxy compound (XLVI) is hydrolyzed using an alkali hydroxide, followed by acidification, to give the amide forming agent (IX-XLVII). The amide forming agent (XLVII) is then coupled with amine (VIII) using methods known to those skilled in the art and methods previously discussed, such as with diethyl cyanophosphonate, to give the substituted amine (X).

Further treatment of the substituted amine (X) with diethyl cyanophosphonate gives the substituted amine where the hydroxyalkyl substitutent on the phenyl ring has a phosphate substitutent.

CHART M discloses a process to prepare amide forming agents (IX-L) where the RN substituent is RN_1-XN-, where the linker,-XN-is-CO-, where RN-1 is RN_aryl and where RN_aryl is phenyl (-phenyl) substituted with two groups. The first substituent at what is usually identified as position"5-"can be either: -RN-aryl or - RN-heteroaryl. The second substituent at what is usually identified as postion"3-"can be either: -CO-NRN-2RN-3 or -CO-RN4. RNalpha and RNbeta include both the non-cyclic amides,-CO-NRN-2RN-3 and the cyclic amides-CO-RN-4 where RN-2, RN-3 and RN-4 are as defined in the claims. The process starts with the trisubstituted phenyl compound (XLVIII) where RN-d is-Cl, -Br,-I or-0-triflate. Treatment with an aryl or heteroaryl boronic acid or heteroaryl or aryl boronic acid ester such as (aryl or heteroaryl) -B (OH) 2 or (aryl or heteroaryl)-B (ORa) (ORb) (where Ra and Rb are lower alkyl, ie. C1-C6, or taken together, Ra and Rb are lower alkylene, ie. C2-C12) in the presence of a metal catalyst with or without a base in an inert solvent yields (XLIX). Metal catalysts in these transformations include, but are not limited to, salts or phosphine complexes of Cu, Pd, or Ni (eg. Cu (OAc) 2, PdCl2 (PPh3) 2, NiCl2 (PPh3) 2).

Bases may include, but are not limited to, alkaline earth metal carbonates, alkaline earth metal bicarbonates, alkaline earth metal hydroxides, alkali metal carbonates, alkali metal bicarbonates, alkali metal hydroxides, alkali metal hydrides (preferably sodium hydride), alkali metal alkoxides (preferably sodium methoxide or sodium ethoxide), alkaline earth metal hydrides, alkali metal dialkylamides (preferably lithium diisopropylamide), alkali metal bis (trialkylsilyl) amides (preferably sodium

bis (trimethylsilyl) amide), trialkyl amines (preferably diisopropylethylamine or triethylamine) or aromatic amines (preferably pyridine). Inert solvents may include, but are not limited to, acetonitrile, dialkyl ethers (preferably diethyl ether), cyclic ethers (preferably tetrahydrofuran or 1,4-dioxane), N, N-dialkylacetamides (preferably dimethylacetamide), N, N-dialkylformamides (preferably dimethylformamide), dialkylsulfoxides (preferably dimethylsulfoxide), aromatic hydrocarbons (preferably benzene or toluene) or haloalkanes (preferably methylene chloride). Preferred reaction temperatures range from room temperature up to the boiling point of the solvent employed. The reactions may be run in conventional glassware or in one of many commercially available parallel synthesizer units. Non-commercially available boronic acids or boronic acid esters may be obtained from the corresponding optionally substituted aryl halide as described in Tetrahedron, 50,979-988 (1994). Intermediate (XLIX) is then hydrolyzed using alkali metal hydroxide, for example lithium, sodium or potassium hydroxide, followed by acidification, to give aryl or heteroaryl coupled acids (IX-L). Alternatively, as described in Tetrahedron, 50, 979-988 (1994), one may convert the RN_d to the corresponding boronic acid or boronic acid ester (OH) 2B- or (ORa) (ORb) B- and obtain the same products set forth above by treating with a suitable aryl or heteroaryl halide or triflate.

CHART N discloses a process to prepare amide forming agents (IX-LII) where the RN substituent is RN_1-XN-where the linker,-XN-is-CO-, where RN-1 is RN_aryl and where RN-aryl is phenyl (-phenyl) substituted with two groups. The first substitutent at what is usually identified as postion"5-"is- C-C-R. The second substituent at what is usually identified as

postion"3-"can be either-CO-NRN-2RN-3 or-CO-RN4. The halo ester (XXI) is treated with a mixture of PdCl2 (Pphenyl3) 2 and trimethylsilyl acetylene, using methods known to those skilled in the art, to give acetylene ester (LI). Acetylene ester (LI) is then hydrolyzed using alkali metal hydroxide, followed by acidification, to give acetylene acid (IX-LII).

CHARTs O and 0'disclose processes to prepare amide forming agents (IX-LX) and (IX-LXIII) with an extended methylene group where the RN substituent is RN_1-XN-where the linker, -XN-is-CO-, where RN-1 is RN-aryl and where RN-aryl is phenyl (-phenyl) substituted with two groups. The substituent at what is usually identified as postion"3-"can be either- CO-NRN-2RN-3 or-CO-RN-4. In the process of CHART 0, the substituent at the 5-position is-CH2CO-NH2 and in the process of CHART O', the substituent at the 5-position is-CH2C=N.

The starting diester acid (LIII) is reduced with borane in solvents such as THF to give the corresponding diester alcohol (LIV). The diester alcohol (LIV) is converted to the corresponding diester bromo compound (LV) using a brominating agent such as PBr3, CBr4, or other halogenating agent such as are known to those skilled in the art. The bromine of the diester bromo compound (LV) is then displaced with cyanide to give the corresponding nitrile (LVI). In CHART O', the nitrile (LVI) is then hydrolyzed to the corresponding cyano ester (LXI). The cyano ester (LXI) is then coupled with H-NRNaRNp (AMINE), as previously described using methods known to those skilled in the art to give the corresponding cyano amide (LXII). The cyano amide (LXII) is then hydrolyzed to the corresponding cyano acid (IX-LXIII) which is in turn coupled with amine (VIII) to give the substituted amine (X). When the substitutent on the extended methyl group is-CO-NH2, the process of CHART O is used. There the nitrile (LVI) is converted to the corresponding diester amine (LVII) by methods known to those skilled in the art. The next steps are the same

as for CHART O'where the diester amide (LVII) is hydrolyzed to the corresponding ester amine (LVIII) which is then converted to the corresponding diamide ester (LIX) which is hydrolyzed to the corresponding diamide acid (IX-LX). The diamide acid (IX - XL) is then coupled with the appropriate amine (VIII) to produce the desired substituted amide (X).

CHART P discloses a process to prepare amide forming agents (IX-LXVII) with an extended hydroxymethylene group where the RN substituent is RN_1-XN-where the linker,-XN-is- CO-, where the RN-1 is RN-aryl, where RN-aryl is phenyl (-phenyl) substituted with two groups. The substituent at what is usually identified as position"3-"can be either-CO-NRN-2RN-3 or-CO-RN 4. The process begins with a halo amide (LXIV), preferably iodo, which is converted to the corresponding aldehyde (LXV) and then to the corresponding alcohol (LXVI) by the method described in Synth. Commun. 28,4270 (1998), optionally with variations known to those skilled in the art. Hydrolysis of the alcohol (LXVI) using alkali hydroxides, followed by acidification, gives the desired hydroxy acid (IX-LXVII).

The hydroxy acid (IX-LXVII) is then coupled with the appropriate amine (VIII) to give the desired substituted amine (X).

CHART Q discloses a process to prepare amide forming agents (IX-LXXII) with an alkyl group or a halogen atom or an amino group at the 5-position where the RN substituent is R. N-i- XN-where the linker,-XN-is-CO-, where the RN-1 is -aryl/ where RNaryl is phenyl (-phenyl) substituted with two groups.

The substituent at what is usually identified as position"3-" can be either-CO-NRN-2RN-3 or-CO-RN_4. The process begins with an appropriately 5-substituted diacid (LXVIII) which is esterified by methods known to those skilled in the art to give the corresponding diester (LXIX). The diester (LXIX) is then hydrolyzed using alkali hydroxides, followed by acidification, to give the corresponding monoacid (LXX). Alternatively, the

monoacid (LXX) can be produced directly from the diacid (LXVIII) by known methods. The monoacid (LXX) is then coupled with H-NRNalphaRNbeta (AMINE) to give the corresponding amide ester (LXXI). The amide ester (LXXI) is then hydrolyzed using alkali hydroxides, followed by acidification, to give the corresponding acid amide (IX- LXXII).

CHART R discloses a general process to prepare the amide forming agents (IX-LXXVII) which, for example, have an alkyl group at what is known as the 5-position and a ketone at the 3- position. These acids (IX-LXXVII) are formed by starting with the acid (LXXIII) which is converted to the corresponding acid halide (LXXIV) using methods known to those skilled in the art. The acid halide (LXXIV) is preferrably the acid chloride.

The acid halide (LXXIV) in the presence of copper (I) bromide and tetrahydrofuran and at temperatures ranging from-78 degrees C to 0 degrees is treated with a Grignard reagent (aryl-Mg-X, or alkyl-Mg-X, where X is-Cl or-Br) to give the ketone esters (LXXVI and LXXVI'). Many Grignard reagents are available for purchase; others are prepared by methods known to those skilled in the art. An alternative method for preparing the ketone esters (LXXVI, LXXVI') is to prepare the Weinreb amide (LXXV), either from the acid (LXXIII) directly or by way of acid halide (LXXIV) followed by treatment with N, 0- dimethylhydroxylamine to give Weinreb amide (LXXV) and then treating the Weinreb amide (LXXV) with a Grignard reagent, by methods known to those skilled in the art. The ketone esters (LXXVI, LXXVI') are then hydrolyzed using alkali hydroxides, followed by acidification, to give the ketone acids (LXXVII, LXXVII').

CHART S discloses various methods to modify the RN portion of the substituted amine (X) where the phenyl ring of the RN moiety is further substituted in the 3-position with various groups such as aryl and heteroaryl. These compounds are

prepared by methods known to those skilled in the art. The process chemistry of each reaction is known to those skilled in the art. What is novel here is the order of each process step and/or the specific reactants used. One skilled in the art knowing the desired product would know at least one method to prepare the desired product by using known starting materials.

Hence, the following discussion is not necessary but is set forth to further aid those interested in preparing the compounds of the invention.

CHART S sets forth a general method used in the invention to prepare the substitued amines (X) where RN = RN-aryl-RN- aryl-XN or RN-heteroaryl-RN-aryl-XN Treatment of the (S, R)- amine (VIII) with amide forming agents (IX) according to the methods set forth above where for CHART S, RN_1is Br-RN_aryl generates the corresponding (S, R) -substituted amine (X) where RN is Br-NR-aryl-XN Further treatment with an aryl boronic acid or aryl boronic acid ester such as (aryl or heteroaryl)- B (OH) 2 or (aryl or heteroaryl)-B (ORa) (ORb) (where Ra and Rb are lower alkyl, ie. C1-C6, or taken together, Ra and Rb are lower alkylene, ie. C2-C12) in the presence of a metal catalyst with or without a base in an inert solvent yields the (S, R)- substituted amine (X) where RN is NR-aryl-NR-aryl-XN or RN_ heteroaryl-RN-aryl-XN-Metal catalysts in these transformations include, but are not limited to, salts or phosphine complexes of Cu, Pd, or Ni (eg. Cu (OAc) 2, PdCl2 (PPh3) 2, NiCl2 (PPh3) 2). Bases may include, but are not limited to, alkaline earth metal carbonates, alkaline earth metal bicarbonates, alkaline earth metal hydroxides, alkali metal carbonates, alkali metal bicarbonates, alkali metal hydroxides, alkali metal hydrides (preferably sodium hydride), alkali metal alkoxides (preferably sodium methoxide or sodium ethoxide), alkaline earth metal hydrides, alkali metal

dialkylamides (preferably lithium diisopropylamide), alkali metal bis (trialkylsilyl) amides (preferably sodium bis (trimethylsilyl) amide), trialkyl amines (preferably diisopropylethylamine or triethylamine) or aromatic amines (preferably pyridine). Inert solvents may include, but are not limited to, acetonitrile, dialkyl ethers (preferably diethyl ether), cyclic ethers (preferably tetrahydrofuran or 1,4- dioxane), N, N-dialkylacetamides (preferably dimethylacetamide), N, N-dialkylformamides (preferably dimethylformamide), dialkylsulfoxides (preferably dimethylsulfoxide), aromatic hydrocarbons (preferably benzene or toluene) or haloaalkanes (preferably methylene chloride). Preferred reaction temperatures range from room temperature up to the boiling point of the solvent employed. The reactions may be run in conventional glassware or in one of many commercially available parallel synthesizer units. Non-commercially available boronic acids or boronic acid esters may be obtained from the corresponding optionally substituted aryl halide as described in Tetrahedron, 50, 979-988 (1994).

Where the above chemistry is incompatible with other functionality in the (S, R) -substituted amine (X) where RN is Br-NR-aryl-XN, then one skilled in the art will readily understand that an alternative sequence of coupling steps is required. For example, treatment of an appropriately substituted amide forming agent (IX) RN_1-XN-OH where RN_1 is Br-RN_aryl with a boronic acid or boronic acid ester under the conditions described above will afford the appropriately substituted amide forming agent (IX) where RN-1 is NR-aryl-NR- aryl or RN-heteroaryl-RN-aryl-When the amide forming agent (IX) where RN_1 is NR_aryl-NR-aryl or RN-heteroaryl-RN-aryl is treated with the (S, R) -amine (VIII), one then obtains the same substituted amines (X) set forth in CHART S.

The above examples for CHART S are not meant to limit the scope of the chemistry. In addition to bromine, a suitable group may include iodine or triflate. Alternatively, as described in Tetrahedron, 50,979-988 (1994), one may convert the Br-RN_aryl to the corresponding boronic acid or boronic acid ester (OH) 2B-RN_aryl or (ORa) (ORb) B-RN_aryl and obtain the same products set forth above by treating with a suitable aryl or heteroaryl halide or triflate. Additionally, each-RN_aryl and-RN-heteroaryl are interchangeable at each occurrence in the chemistry described above.

CHART T discloses a process to prepare amide forming agents (IX-LXXIX) where the RN substituent is RN1-XN-, where the linker, -XN-is-CO-, where RN-1 is RN_aryl and where RN_aryl is phenyl substituted with-CO-NRNalphaRNbeta (AMINE) and with an amide of the formulas: - (CH2) 0-4-N (-H and RN-5)-CO-RN-2 -(CH2) 04-N (-H or RN-5)-S02-RN-2.

The process begins with the amide aniline (XXXI) which is reacted with the corresponding acid halide or sulfonyl halide, or acid anhydride or sulfonyl anhydride to produce the corresponding amide ester (LXXVIII). Suitable solvents include THF or dichloromethane at temperatures ranging from-78 degrees to 100 degrees C. The amide ester (LXXVIII) is then hydrolyzed to the corresponding amide acid (IX-LXXIX) by methods known to those skilled in the art. When the amide forming agent (IX - LXXIX) is reacted with the appropriate amine (VIII), the desired compound (X) is obtained.

CHART U discloses a general method for preparing various C-terminal amines (VI) as reed by the preparation of C-terminal amine (LXXXIV). Methods to prepare amines of this type are well understood using methods known to those skilled in the art, or one may consult the references: 1) JACS, 1970, 92, 3700, and 2) US patent 4,351, 842.

CHART V further discloses general methods for preparing various C-terminal amines (VI) as reed by the preparation of C-terminal amines (LXXXIX). Multiple examples of the heterocyclic carboxylic acids or acid chlorides are commercially available. Optionally, the carboxylic acid (LXXXV) may be converted to the acid chloride (LXXXVI) with reagents such as, but not limited to, thionyl chloride.

Displacement with ammonia generates the common intermediate amides (LXXXVII) which are readily reduced to amines (VI- LXXXIX) using a variety of methods detailed previously.

Alternatively, other heteroaryls are commecially available as the methyl halide (LXXXVIII) which are treated with ammonia to yield the title C-terminal amines (VI- LXXXVIII).

CHART W discloses general methods for preparing thiazolyl containing C-terminal amines as reed by the preparation of C-terminal amines (LXXXXI). The synthesis of the thiazoles is outlined in CHART W; these procedures are amply taught in the literature and are modified from the procedures outlined in: Mashraqui, SH; Keehn, PM. J. Am.

Chem. Soc. 1982, 104, 4461-4465. The synthesis of substituted 5-aminomethylthiazoles (XCI) was achieved from 5-hydroxymethylthiazole (XC) by the procedure described in: Alterman et al. J. Med. Chem. 1998, 41, 3782-3792. All other thiazole analogs were transformed to the hydroxymethyl derivative using CHART W, and converted to the aminomethyl derivative by the Alterman procedure without notable changes.

CHART X discloses general methods for preparing isoxazolyl containing C-terminal amines as reed by the preparation of C- terminal amines (XCII). The synthesis of isoxazole derivatives was modified from the procedure in: Felman, SW et al. J. Med.

Chem. 1992, 35, 1183-1190 and is readily understood by those skilled in the art making non-notable changes to achieve the

title compounds. The substituted, hydroxylamine precursors were synthesized using the procedure taught by Bousquet, EW. Org.

Synth. Coll. Vol II, 313-315. Commercially available propargylamine may be protected using any number of methods known in the art (see: Greene, TW; Wuts, PGM. Protective Groups in Organic Synthesis, 3rd Ed. New York: John Wiley, 1999.

Chapter 7. ), prefered is a BOC protecting group. Substituted propargyl amines may be obtained by a number of methods commonly known in the art.

CHART Y discloses a general route to prepare hydroxyethylamines where one carbon atom of the peptide backbone, along with R2 and R3 form a ring. It is understood that the invention also allows for a heteroatom to be incorporated into the ring. In summary, the synthesis of compounds where R2 and R3 may form a ring proceeds from a suitably protected amino acid aldehyde and cycloalkyllithium species, both of which are commercially available or where known procedures for making such compounds are known in the art. The general procedure involved is also precedent in the literature, for example, see Klumpp, et al., J. Am. Chem. Soc., 1979, 101, 7065, and it is intended that making non-critical variations, one may obtain the title compounds provided for by CHART Y. Treatment of a suitably protected amino acid aldehyde and cycloalkyllithium species affords alcohol (XCIII). These reactions are carried out in an inert solvent such as, for example, tetrahydrofuran or diethyl ether. Optimally the reactions are conducted at low temperatures, for example below 0 degrees C. Carbonylation via the Klumpp procedure yields the acid (XCIV) which when exposed to Curtius, or related procedures well known to those skilled in the art, generates the primary amine (XCV). The primary amines (XCV) may be capped C-terminally via the conditions set forth in CHART C & D followed by nitrogen deprotection and capping N-terminally via the conditions set forth in CHART A.

The compounds of the invention may contain geometric or optical isomers as well as tautomers. Thus, the invention includes all tautomers and pure geometric isomers, such as the E and Z geometric isomers, as well as mixtures thereof.

Futhermore, the invention includes pure enantiomers and diasteriomers as well as mixtures thereof, including racemic mixtures. The individual geometric isomers, enantiomers, or diasteriomers may be prepared or isolated by methods known in the art.

Compounds of the invention with the stereochemistry designated in formula X may be included in mixtures, including racemic mixtures, with other enantiomers, diasteriomers, geometric isomers or tautomers. Compounds of the invention with the stereochemistry designated in formula X are typically in these mixtures in excess of 50 percent. Preferably, compounds of the invention with the stereochemistry designated in formula X are in these mixtures in excess of 80 percent.

Most preferably, compounds of the invention with the stereochemistry designated in formula X are in these mixtures in excess of 90 percent.

The compounds of the invention are typically amines and as such form salts when reacted with acids. Pharmaceutically acceptable salts are preferred over the corresponding (S, R)- substituted amines (X) and and the substituted amines with RN cyclized (X') since they produce compounds which are more water soluble, stable and/or more crystalline. Pharmaceutically acceptable salts are any salt which retains the activity of the parent compound and does not impart any deleterious or undesirable effect on the subject to whom it is administered and in the context in which it is administered. Pharm- aceutically acceptable salts include salts of both inorganic and organic acids. The preferred pharmaceutically acceptable salts include salts of the following acids acetic, aspartic, benzenesulfonic, benzoic, bicarbonic, bisulfuric, bitartaric,

butyric, calcium edetate, camsylic, carbonic, chlorobenzoic, citric, edetic, edisylic, estolic, esyl, esylic, formic, fumaric, gluceptic, gluconic, glutamic, glycollylarsanilic, hexamic, hexylresorcinoic, hydrabamic, hydrobromic, hydrochloric, hydroiodic, hydroxynaphthoic, isethionic, lactic, lactobionic, maleic, malic, malonic, mandelic, methanesulfonic, methylnitric, methylsulfuric, mucic, muconic, napsylic, nitric, oxalic, p-nitromethanesulfonic, pamoic, pantothenic, phosphoric, monohydrogen phosphoric, dihydrogen phosphoric, phthalic, polygalactouronic, propionic, salicylic, stearic, succinic, succinic, sulfamic, sulfanilic, sulfonic, sulfuric, tannic, tartaric, teoclic and toluenesulfonic. For other acceptable salts, see Int. J. Pharm., 33,201-217 (1986) and J. Pharm. Sci., 66 (1), 1, (1977).

The invention provides compounds, compositions, kits, and methods for inhibiting beta-secretase enzyme activity and A beta peptide production. Inhibition of beta-secretase enzyme activity halts or reduces the production of A beta from APP and reduces or eliminates the formation of beta-amyloid deposits in the brain.

Methods of the Invention The compounds of the invention, and pharmaceutically acceptable salts thereof, are useful for treating humans or animals suffering from a condition characterized by a pathological form of beta-amyloid peptide, such as beta-amyloid plaques, and for helping to prevent or delay the onset of such a condition. The compounds and compositions of the invention are particularly useful for treating or preventing Alzheimer's disease. The compounds of the invention can either be used individually or in combination, as is best for the patient.

As used herein, the term"treating"means that the compounds of the invention can be used in humans with at least a tentative diagnosis of disease. The compounds of the

invention will delay or slow the progression of the disease thereby giving the individual a more useful life span.

The term"preventing"means that the compounds of the invention are useful when administered to a patient who has not been diagnosed as possibly having the disease at the time of administration, but who would normally be expected to develop the disease or be at increased risk for the disease. The compounds of the invention will slow the development of disease symptoms, delay the onset of the disease, or prevent the individual from developing the disease at all. Preventing also includes administration of the compounds of the invention to those individuals thought to be predisposed to the disease due to age, familial history, genetic or chromosomal abnormalities, and/or due to the presence of one or more biological markers for the disease, such as a known genetic mutation of APP or APP cleavage products in brain tissues or fluids.

In treating or preventing the above diseases, the compounds of the invention are administered in a therapeutically effective amount. The therapeutically effective amount will vary depending on the particular compound used and the route of administration, as is known to those skilled in the art.

In addition, the compounds of the invention can also be used with inhibitors of P-glycoproten (P-gp). The use of P-gp inhibitors is known to those skilled in the art. See for example, Cancer Research, 53,4595-4602 (1993), Clin. Cancer Res., 2,7-12 (1996), Cancer Research, 56,4171-4179 (1996), International Publications W099/64001 and WO01/10387. The important thing is that the blood level of the P-gp inhibitor be such that it exerts its effect in inhibiting P-gp from decreasing brain blood levels of the compounds of the invention. To that end the P-gp inhibitor and the compounds of the invention can be administered at the same time, by the same or different route of administration, or at different times.

The important thing is not the time of administration but having an effective blood level of the P-gp inhibitor.

Suitable P-gp inhibitors include cyclosporin A, verapamil, tamoxifen, quinidine, Vitamin E-TGPS, ritonavir, megestrol acetate, progesterone, rapamycin, 10,11-methanodibenzosuberane, phenothiazines, acridine derivatives such as GF120918, FK506, VX-710, LY335979, PSC-833, GF-102,918 and other steroids. It is to be understood that additional agents will be found that do the same function and are also considered to be useful.

The P-gp inhibitors can be administered orally, parenterally, (IV, IM, IM-depo, SQ, SQ-depo), topically, sublingually, rectally, intranasally, intrathecally and by implant.

The therapeutically effective amount of the P-gp inhibitors is from about 0.1 to about 300 mg/kg/day, preferably about 0.1 to about 150 mg/kg daily. It is understood that while a patient may be started on one dose, that dose may have to be varied over time as the patient's condition changes.

When administered orally, the P-gp inhibitors can be administered in usual dosage forms for oral administration as is known to those skilled in the art. These dosage forms include the usual solid unit dosage forms of tablets and capsules as well as liquid dosage forms such as solutions, suspensions and elixirs. When the solid dosage forms are used, it is preferred that they be of the sustained release type so that the P-gp inhibitors need to be administered only once or twice daily. The oral dosage forms are administered to the patient one thru four times daily. It is preferred that the P- gp inhibitors be administered either three or fewer times a day, more preferably once or twice daily. Hence, it is preferred that the P-gp inhibitors be administered in solid dosage form and further it is preferred that the solid dosage form be a sustained release form which permits once or twice daily dosing. It is preferred that what ever dosage form is

used, that it be designed so as to protect the P-gp inhibitors from the acidic environment of the stomach. Enteric coated tablets are well known to those skilled in the art. In addition, capsules filled with small spheres each coated to protect from the acidic stomach, are also well known to those skilled in the art.

In addition, the P-gp inhibitors can be administered parenterally. When administered parenterally they can be administered IV, IM, depo-IM, SQ or depo-SQ.

The P-gp inhibitors can be given sublingually. When given sublingually, the P-gp inhibitors should be given one thru four times daily in the same amount as for IM administration.

The P-gp inhibitors can be given intranasally. When given by this route of administration, the appropriate dosage forms are a nasal spray or dry powder as is known to those skilled in the art. The dosage of the P-gp inhibitors for intranasal administration is the same as for IM administration.

The P-gp inhibitors can be given intrathecally. When given by this route of administration the appropriate dosage form can be a parenteral dosage form as is known to those skilled in the art.

The P-gp inhibitors can be given topically. When given by this route of administration, the appropriate dosage form is a cream, ointment or patch. Because of the amount of the P-gp inhibitors needed to be administered the patch is preferred.

However, the amount that can be delivered by a patch is limited. Therefore, two or more patches may be required. The number and size of the patch is not important, what is important is that a therapeutically effective amount of the P- gp inhibitors be delivered as is known to those skilled in the art.

The P-gp inhibitors can be administered rectally by suppository as is known to those skilled in the art.

The P-gp inhibitors can be administered by implants as is known to those skilled in the art.

There is nothing novel about the route of administration nor the dosage forms for administering the P-gp inhibitors.

Given a particular P-gp inhibitor, and a desired dosage form, one skilled in the art would know how to prepare the appropriate dosage form for the P-gp inhibitor.

It should be apparent to one skilled in the art that the exact dosage and frequency of administration will depend on the particular compounds of the invention administered, the particular condition being treated, the severity of the condition being treated, the age, weight, general physical condition of the particular patient, other medication the individual may be taking as is well known to those skilled in the art.

Dosage forms and amounts The compounds of the invention can be administered orally, parenternally, (IV, IM, depo-IM, SQ, and depo SQ), sublingually, intranasally (inhalation), intrathecally, topically, or rectally.

About 1 to 500 mg of a compound or mixture of compounds of the invention or a physiologically acceptable salt or ester is

compounded with a physiologically acceptable vehicle, carrier, excipient, binder, preservative, stabilizer, flavor, etc. , in a unit dosage form as called for by accepted pharmaceutical practice. The amount of active substance in those compositions or preparations is such that a suitable dosage in the range indicated is obtained. The compositions are preferably formulated in a unit dosage form, each dosage containing from about 2 to about 100 mg, more preferably about 10 to about 30 mg of the active ingredient. The term"unit dosage from" refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient.

To prepare compositions, one or more compounds of the invention are mixed with a suitable pharmaceutically acceptable carrier. Upon mixing or addition of the compound (s), the resulting mixture may be a solution, suspension, emulsion, or the like. Liposomal suspensions may also be suitable as pharmaceutically acceptable carriers. These may be prepared according to methods known to those skilled in the art. The form of the resulting mixture depends upon a number of factors, including the intended mode of administration and the solubility of the compound in the selected carrier or vehicle.

The concentration of active compound in the drug composition will depend on absorption, inactivation, and excretion rates of the active compound, the dosage schedule, and amount administered as well as other factors known to those of skill in the art.

The active ingredient may be administered at once, or may be divided into a number of smaller doses to be administered at intervals of time. It is understood that the precise dosage and duration of treatment is a function of the disease being treated and may be determined empirically using known testing protocols or by extrapolation from in vivo or in vitro test data. It is to be noted that concentrations and dosage values may also vary with the severity of the condition to be alleviated. It is to be further understood that for any particular subject, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the compositions, and that the concentration ranges set forth herein are exemplary only and are not intended to limit the scope or practice of the claimed compositions.

If oral administration is desired, the compound should be provided in a composition that protects it from the acidic environment of the stomach. For example, the composition can be formulated in an enteric coating that maintains its

integrity in the stomach and releases the active compound in the intestine. The composition may also be formulated in combination with an antacid or other such ingredient.

Parenternal preparations can be enclosed in ampoules, disposable syringes, or multiple dose vials made of glass, plastic, or other suitable material.

Buffers, preservatives, antioxidants, and the like can be incorporated as required.

Where administered intravenously, suitable carriers include physiological saline, phosphate buffered saline (PBS), and solutions containing thickening and solubilizing agents such as glucose, polyethylene glycol, polypropyleneglycol, and mixtures thereof. Liposomal suspensions including tissue- targeted liposomes may also be suitable as pharmaceutically acceptable carriers. These may be prepared according to methods known for example, as described in U. S. Patent No.

4,522, 811.

The active compounds may be prepared with carriers that protect the compound against rapid elimination from the body, such as time-release formulations or coatings. Such carriers include controlled release formulations, such as, but not

limited to, implants and microencapsulated delivery systems, and biodegradable, biocompatible polymers such as collagen, ethylene vinyl acetate, polyanhydrides, polyglycolic acid, polyorthoesters, polylactic acid, and the like. Methods for preparation of such formulations are known to those skilled in the art.

Compounds of the invention may be administered enterally or parenterally. When administered orally, compounds of the invention can be administered in usual dosage forms for oral administration as is well known to those skilled in the art.

These dosage forms include the usual solid unit dosage forms of tablets and capsules as well as liquid dosage forms such as solutions, suspensions, and elixirs. When the solid dosage forms are used, it is preferred that they be of the sustained release type so that the compounds of the invention need to be administered only once or twice daily.

The oral dosage forms are administered to the patient 1, 2,3, or 4 times daily. It is preferred that the compounds of the invention be administered either three or fewer times, more preferably once or twice daily. Hence, it is preferred that the compounds of the invention be administered in oral dosage form. It is preferred that whatever oral dosage form is used, that it be designed so as to protect the compounds of the invention from the acidic environment of the stomach. Enteric coated tablets are well known to those skilled in the art. In addition, capsules filled with small spheres each coated to protect from the acidic stomach, are also well known to those skilled in the art.

When administered orally, an administered amount therapeutically effective to inhibit beta-secretase activity, to inhibit A beta production, to inhibit A beta deposition, or to treat or prevent AD is from about 0.1 mg/day to about 1,000 mg/day. It is preferred that the oral dosage is from about 1 mg/day to about 100 mg/day. It is more preferred that the oral dosage is from about 5 mg/day to about 50 mg/day. It is understood that while a patient may be started at one dose, that dose may be varied over time as the patient's condition changes.

Compounds of the invention may also be advantageously delivered in a nano crystal dispersion formulation.

Preparation of such formulations is described, for example, in U. S. Patent 5,145, 684. Nano crystalline dispersions of HIV protease inhibitors and their method of use are described in US 6,045, 829. The nano crystalline formulations typically afford greater bioavailability of drug compounds.

The compounds of the invention can be administered parenterally, for example, by IV, IM, depo-IM, SC, or depo-SC.

When administered parenterally, a therapeutically effective amount of about 0.5 to about 100 mg/day, preferably from about 5 to about 50 mg daily should be delivered. When a depot formulation is used for injection once a month or once every two weeks, the dose should be about 0.5 mg/day to about 50 mg/day, or a monthly dose of from about 15 mg to about 1,500 mg. In part because of the forgetfulness of the patients with Alzheimer's disease, it is preferred that the parenteral dosage form be a depo formulation.

The compounds of the invention can be administered sublingually. When given sublingually, the compounds of the invention should be given one to four times daily in the amounts described above for IM administration.

The compounds of the invention can be administered intranasally. When given by this route, the appropriate dosage

The compounds of the invention can be administered intrathecally. When given by this route the appropriate dosage form can be a parenternal dosage form as is known to those skilled in the art. The dosage of the compounds of the invention for intrathecal administration is the amount described above for IM administration.

The compounds of the invention can be administered topically. When given by this route, the appropriate dosage form is a cream, ointment, or'patch. Because of the amount of the compounds of the invention to be administered, the patch is preferred. When administered topically, the dosage is from about 0.5 mg/day to about 200 mg/day. Because the amount that can be delivered by a patch is limited, two or more patches may be used. The number and size of the patch is not important, what is important is that a therapeutically effective amount of the compounds of the invention be delivered as is known to those skilled in the art. The compounds of the invention can be administered rectally by suppository as is known to those skilled in the art. When administered by suppository, the therapeutically effective amount is from about 0.5 mg to about 500 mg.

The invention here is the new compounds of the invention and new methods of using the compounds of the invention. Given a particular compound of the invention and a desired dosage

Neurol. 57: 454), and other neurotropic agents of the future.

It should be apparent to one skilled in the art that the exact dosage and frequency of administration will depend on the particular compounds of the invention administered, the particular condition being treated, the severity of the condition being treated, the age, weight, general physical condition of the particular patient, and other medication the individual may be taking as is well known to administering physicians who are skilled in this art.

Inhibition of APP Cleavage The compounds of the invention inhibit cleavage of APP between Met595 and Asp596 numbered for the APP695 isoform, or a mutant thereof, or at a corresponding site of a different isoform, such as APP751 or APP770, or a mutant thereof (sometimes referred to as the"beta secretase site").

Inhibitory activity is demonstrated in one of a variety of inhibition assays, whereby cleavage of an APP substrate in the presence of a beta-secretase enzyme is analyzed in the presence of the inhibitory compound, under conditions normally sufficient to result in cleavage at the beta-secretase cleavage site. Reduction of APP cleavage at the beta-secretase cleavage site compared with an untreated or inactive control is correlated with inhibitory activity. Assay systems that can be used to demonstrate efficacy of the compound inhibitors of the invention are known. Reative assay systems are described, for example, in U. S. Patents No. 5,942, 400,5, 744,346, as well as in the Examples below.

The enzymatic activity of beta-secretase and the production of A beta can be analyzed in vitro or in vivo, using natural, mutated, and/or synthetic APP substrates, natural, mutated, and/or synthetic enzyme, and the test compound. The analysis may involve primary or secondary cells expressing native, mutant, and/or synthetic APP and enzyme, animal models expressing native APP and enzyme, or may utilize transgenic

animal models expressing the substrate and enzyme. Detection of enzymatic activity can be by analysis of one or more of the cleavage products, for example, by immunoassay, flurometric or chromogenic assay, HPLC, or other means of detection.

Inhibitory compounds are determined as those having the ability to decrease the amount of beta-secretase cleavage product produced in comparison to a control, where beta-secretase mediated cleavage in the reaction system is observed and measured in the absence of inhibitory compounds.

Beta-secretase Various forms of beta-secretase enzyme are known, and are available and useful for assay of enzyme activity and inhibition of enzyme activity. These include native, recombinant, and synthetic forms of the enzyme. Human beta- secretase is known as Beta Site APP Cleaving Enzyme (BACE), Asp2, and memapsin 2, and has been characterized, for example, in U. S. Patent No. 5,744, 346 and published PCT patent applications W098/22597, WO00/03819, WO01/23533, and WO00/17369, as well as in literature publications (Hussain et. al. , 1999, Mol. Cell. Neurosci. 14: 419-427; Vassar et. al., 1999, Science 286: 735-741; Yan et. al. , 1999, Nature 402: 533- 537 ; Sinha et. al. , 1999, Nature 40: 537-540; and Lin et. al., 2000, PNAS USA 97: 1456-1460). Synthetic forms of the enzyme have also been described (W098/22597 and WO00/17369). Beta- secretase can be extracted and purified from human brain tissue and can be produced in cells, for example mammalian cells expressing recombinant enzyme.

Useful inhibitory compounds are effective to inhibit 50% of beta-secretase enzymatic activity at a concentration of less than 50 micromolar, preferably at a concentration of 10 micromolar or less, more preferably 1 micromolar or less, and most preferably 10 nanomolar or less.

APP substrate Assays that demonstrate inhibition of beta-secretase- mediated cleavage of APP can utilize any of the known forms of APP, including the 695 amino acid"normal"isotype described by Kang et. al. , 1987, Nature 325: 733-6, the 770 amino acid isotype described by Kitaguchi et. al. , 1981, Nature 331: 530-532, and variants such as the Swedish Mutation (KM670-1NL) (APP-SW), the London Mutation (V7176F), and others. See, for example, U. S.

Patent No. 5,766, 846 and also Hardy, 1992, Nature Genet. 1: 233- 234, for a review of known variant mutations. Additional useful substrates include the dibasic amino acid modification, APP-KK disclosed, for example, in WO 00/17369, fragments of APP, and synthetic peptides containing the beta-secretase cleavage site, wild type (WT) or mutated form, e. g. , SW, as described, for example, in U. S. Patent No 5,942, 400 and WO00/03819.

The APP substrate contains the beta-secretase cleavage site of APP (KM-DA or NL-DA) for example, a complete APP peptide or variant, an APP fragment, a recombinant or synthetic APP, or a fusion peptide. Preferably, the fusion peptide includes the beta-secretase cleavage site fused to a peptide having a moiety useful for enzymatic assay, for example, having isolation and/or detection properties. A useful moiety may be an antigenic epitope for antibody binding, a label or other detection moiety, a binding substrate, and the like.

Antibodies Products characteristic of APP cleavage can be measured by immunoassay using various antibodies, as described, for example, in Pirttila et. al. , 1999, Neuro. Lett. 249: 21-4, and in U. S. Patent No. 5,612, 486. Useful antibodies to detect A beta include, for example, the monoclonal antibody 6E10 (Senetek, St. Louis, MO) that specifically recognizes an epitope on amino acids 1-16 of the A beta peptide; antibodies 162 and 164 (New

York State Institute for Basic Research, Staten Island, NY) that are specific for human A beta 1-40 and 1-42, respectively; and antibodies that recognize the junction region of beta- amyloid peptide, the site between residues 16 and 17, as described in U. S. Patent No. 5,593, 846. Antibodies raised against a synthetic peptide of residues 591 to 596 of APP and SW192 antibody raised against 590-596 of the Swedish mutation are also useful in immunoassay of APP and its cleavage products, as described in U. S. Patent Nos. 5,604, 102 and 5,721, 130.

Assay Systems Assays for determining APP cleavage at the beta-secretase cleavage site are well known in the art. Exemplary assays, are described, for example, in U. S. Patent Nos. 5,744, 346 and 5,942, 400, and described in the Examples below.

Cell free assays Exemplary assays that can be used to demonstrate the inhibitory activity of the compounds of the invention are described, for example, in WO00/17369, WO 00/03819, and U. S.

Patents No. 5,942, 400 and 5,744, 346. Such assays can be performed in cell-free incubations or in cellular incubations using cells expressing a beta-secretase and an APP substrate having a beta-secretase cleavage site.

An APP substrate containing the beat-secretase cleavage site of APP, for example, a complete APP or variant, an APP fragment, or a recombinant or synthetic APP substrate containing the amino acid sequence: KM-DA or NL-DA, is incubated in the presence of beta-secretase enzyme, a fragment thereof, or a synthetic or recombinant polypeptide variant having beta-secretase activity and effective to cleave the beta-secretase cleavage site of APP, under incubation conditions suitable for the cleavage activity of the enzyme.

Suitable substrates optionally include derivatives that may be fusion proteins or peptides that contain the substrate peptide and a modification useful to facilitate the purification or detection of the peptide or its beta-secretase cleavage products. Useful modifications include the insertion of a known antigenic epitope for antibody binding; the linking of a label or detectable moiety, the linking of a binding substrate, and the like.

Suitable incubation conditions for a cell-free in vitro assay include, for example: approximately 200 nanomolar to 10 micromolar substrate, approximately 10 to 200 picomolar enzyme, and approximately 0.1 nanomolar to 10 micromolar inhibitor compound, in aqueous solution, at an approximate pH of 4-7, at approximately 37 degrees C, for a time period of approximately 10 minutes to 3 hours. These incubation conditions are exemplary only, and can be varied as required for the particular assay components and/or desired measurement system. Optimization of the incubation conditions for the particular assay components should account for the specific beta-secretase enzyme used and its pH optimum, any additional enzymes and/or markers that might be used in the assay, and the like. Such optimization is routine and will not require undue experimentation.

One useful assay utilizes a fusion peptide having maltose binding protein (MBP) fused to the C-terminal 125 amino acids of APP-SW. The MBP portion is captured on an assay substrate by anti-MBP capture antibody. Incubation of the captured fusion protein in the presence of beta-secretase results in cleavage of the substrate at the beta-secretase cleavage site.

Analysis of the cleavage activity can be, for example, by immunoassay of cleavage products. One such immunoassay detects a unique epitope exposed at the carboxy terminus of the cleaved fusion protein, for example, using the antibody SW192. This assay is described, for example, in U. S. Patent No 5,942, 400.

Cellular assay Numerous cell-based assays can be used to analyze beta- secretase activity and/or processing of APP to release A beta.

Contact of an APP substrate with a beta-secretase enzyme within the cell and in the presence or absence of a compound inhibitor of the invention can be used to demonstrate beta-secretase inhibitory activity of the compound. Preferably, assay in the presence of a useful inhibitory compound provides at least about 30%, most preferably at least about 50% inhibition of the enzymatic activity, as compared with a non-inhibited control.

In one embodiment, cells that naturally express beta- secretase are used. Alternatively, cells are modified to express a recombinant beta-secretase or synthetic variant enzyme as discussed above. The APP substrate may be added to the culture medium and is preferably expressed in the cells.

Cells that naturally express APP, variant or mutant forms of APP, or cells transformed to express an isoform of APP, mutant or variant APP, recombinant or synthetic APP, APP fragment, or synthetic APP peptide or fusion protein containing the beta- secretase APP cleavage site can be used, provided that the expressed APP is permitted to contact the enzyme and enzymatic cleavage activity can be analyzed.

Human cell lines that normally process A beta from APP provide a useful means to assay inhibitory activities of the compounds of the invention. Production and release of A beta and/or other cleavage products into the culture medium can be measured, for example by immunoassay, such as Western blot or enzyme-linked immunoassay (EIA) such as by ELISA.

Cells expressing an APP substrate and an active beta- secretase can be incubated in the presence of a compound inhibitor to demonstrate inhibition of enzymatic activity as compared with a control. Activity of beta-secretase can be measured by analysis of one or more cleavage products of the

APP substrate. For example, inhibition of beta-secretase activity against the substrate APP would be expected to decrease release of specific beta-secretase induced APP cleavage products such as A beta.

Although both neural and non-neural cells process and release A beta, levels of endogenous beta-secretase activity are low and often difficult to detect by EIA. The use of cell types known to have enhanced beta-secretase activity, enhanced processing of APP to A beta, and/or enhanced production of A beta are therefore preferred. For example, transfection of cells with the Swedish Mutant form of APP (APP-SW); with APP- KK; or with APP-SW-KK provides cells having enhanced beta- secretase activity and producing amounts of A beta that can be readily measured.

In such assays, for example, the cells expressing APP and beta-secretase are incubated in a culture medium under conditions suitable for beta-secretase enzymatic activity at its cleavage site on the APP substrate. On exposure of the cells to the compound inhibitor, the amount of A beta released into the medium and/or the amount of CTF99 fragments of APP in the cell lysates is reduced as compared with the control. The cleavage products of APP can be analyzed, for example, by immune reactions with specific antibodies, as discussed above.

Preferred cells for analysis of beta-secretase activity include primary human neuronal cells, primary transgenic animal neuronal cells where the transgene is APP, and other cells such as those of a stable 293 cell line expressing APP, for example, APP-SW.

In vivo assays: animal models Various animal models can be used to analyze beta- secretase activity and/or processing of APP to release A beta, as described above. For example, transgenic animals expressing APP substrate and beta-secretase enzyme can be used

to demonstrate inhibitory activity of the compounds of the invention. Certain transgenic animal models have been described, for example, in U. S. Patent Nos: 5,877, 399; 5,612, 486 ; 5,387, 742; 5,720, 936; 5,850, 003; 5,877, 015,, and 5,811, 633, and in Ganes et. al. , 1995, Nature 373: 523.

Preferred are animals that exhibit characteristics associated with the pathophysiology of AD. Administration of the compound inhibitors of the invention to the transgenic mice described herein provides an alternative method for demonstrating the inhibitory activity of the compounds. Administration of the compounds in a pharmaceutically effective carrier and via an administrative route that reaches the target tissue in an appropriate therapeutic amount is also preferred.

Inhibition of beta-secretase mediated cleavage of APP at the beta-secretase cleavage site and of A beta release can be analyzed in these animals by measure of cleavage fragments in the animal's body fluids such as cerebral fluid or tissues.

Analysis of brain tissues for A beta deposits or plaques is preferred.

On contacting an APP substrate with a beta-secretase enzyme in the presence of an inhibitory compound of the invention and under conditions sufficient to permit enzymatic mediated cleavage of APP and/or release of A beta from the substrate, the compounds of the invention are effective to reduce beta-secretase-mediated cleavage of APP at the beta- secretase cleavage site and/or effective to reduce released amounts of A beta. Where such contacting is the administration of the inhibitory compounds of the invention to an animal model, for example, as described above, the compounds are effective to reduce A beta deposition in brain tissues of the animal, and to reduce the number and/or size of beta amyloid plaques. Where such administration is to a human subject, the compounds are effective to inhibit or slow the progression of disease characterized by enhanced amounts of A beta, to slow

the progression of AD in the, and/or to prevent onset or development of AD in a patient at risk for the disease.

EXAMPLE SP-135

Compound 14b (1 equiv, 0. 064 mmol, 37.6 mg) was dissolved in EtOAc before the addition of PtO (catalytic) and an H2 balloon.

The reaction was stirred for 4 hours at ambient temperature before LC-MS determined the two products: 15 and 16. The crude mixture was filtered through celite and the solvent was removed in vacuo before isolation by HPLC of each of the products: 15 (13 mg, 34 %, M+H+ = 592. 3) and 16 (16 mg, 42 %, M+H+ = 594. 3)'.

EXAMPLE SP-136

Compound 17 (1 equiv, 0.46 mmol, 0.31 g) was dissolved in CH2C12 and cooled to 0 °C before the addition of Boc20 (1 equiv, 0.46 mmol, 0.1 g) and catalytic DMAP. After the reaction was judged to be done by TLC (4 h), the solvent was simply removed in vacuo and the product was used crude in the next step.

The iodo compound (1 equiv, 0.13 mmol, 100 mg), Pd2dba3 (0.02 equiv, 0.002 mmol, 2.4 mg), dppf (0.08 equiv, 0.01 mmol, 5.8 mg), Et3N (2 equiv, 0. 26 mmol, 0.04 mL), and NMP (0.3 M, 0.4 mL) were added to a sealed tube and flushed/bubbled with N2 (g) for 15 minutes. Ethanethiol was then added and the tube was sealed and stirred for 3h at 60 °C. At this point the reaction was cooled to ambient temperature, diluted with brine, and extracted 3x with EtOAc. The combined organic extracts were then washed with brine (2x), dried over Na2SO4, filtered, and rotovapped to give the crude brown desired thioether. Column chromatography through Si02 with 25 % EtOAc

in hexanes gave the purified product (71.5 mg, 0.1 mmol, 77 %). the thioether 1) equiv, 0.08 mmol, 56.3 mg) was dissolved in ACOH (0.4 mL) and treated with 30 % H202 (0.2 mL). The reaction was stirred 2 h. At this point, the crude mixture was partitioned between EtOAc and H20, and the products were extracted 3x with EtOAc. The organic extracts were dried over Na2S04, filtered, and rotovapped before column chromatography purification through Si02 with 50 % EtOAc in hexanes gave the separated Boc protected sulfone and sulfoxide. After TFA deprotection and HPLC purification, the final products 18 (17 mg, 33%, M+H+ = 644. 2) and 19 (18 mg, 35 %, M+H+ = 628. 3) were achieved.

The aniline (1 equiv, 8.46 mmol, 1 g) was dissolved in pyridine (1 M, 8. 5 mL) and cooled to 0 °C before the addition of methyl chloroformate (1.2 equiv, 10.2 mmol, 0.96 g, 0.78 mL). The reaction was allowed to warm to room temperature overnight with stirring. The reaction mixture was then rotovapped, and H20 was added to the residual oil, at which point a white solid precipitated. The white precipitate was

filtered and washed with H20, and then dried on the vacuum pump overnight to give the clean crude carbamate (1. 4 g, 93%) The carbamate (1 equiv, 3.98 mmol, 0. 70 g) was dissolved in THF (8 mL) and cooled to 0 °C before the addition of a 1M THF solution of KOtBu (1.1 equiv, 4.37 mmol, 4.37 mL). Upon addition of KOtBu, the starting material crashed out of solution, and so more THF was added (5 mL) along with dioxane (2 mL). At this point, despite the continued lack of solubility, MeI (1.1 equiv, 4.37 mmol, 0.62 g, 0.27 mL) was added and the reaction was allowed to warm to room temperature overnight with stirring. After 12 hours, the reaction was still not in solution, and TLC showed incomplete consumption of starting material. Thus, DMF (5 mL) was added and the reaction finally went into solution. After stirring for 5 additional hours at ambient temperature, the reaction was complete. The crude reaction mixture was filtered through celite, rotovapped, partitioned between H20 and EtOAc, extracted 3x with EtOAc, and washed with brine. The organic extracts were dried over Na2SO4, filtered, and rotovapped.

Purification through a short plug of Si02 with 30% EtOAc in hexanes gave the desired methylated carbamate which still contained a colored impurity which was undetected by TLC and NMR. (0.76 g, Quantitative) The nitrile (1 equiv, 3.98 mmol, 0.76 g) was dissolved in ethanol, and N2 (g) was bubbled through the solution for 5 minutes before the addition of AcOH (1 equiv, 3. 98 mmol, 2.27 mL) and 5% DeGussa Pd/C (1 scoop). N2 (g) was bubbled again for 5 minutes before shaking on Parr Shaker at 55 psi H2 overnight. The reaction was filtered through celite and rotovapped to give the acetic acid salt of the desired product. The product was then partitioned between 10% NaOH

(aq) and 20% isopropanol/chloroform, and extracted 3x with 20% isopropanol/chloroform to give the desired free-base.

The crude free-base was used to open the epoxide. The M+H+ mass of the final product is 639.3.

The combined organic extracts were then washed with NaHC03 (aq) and KHS04 (aq), dried over Na2SO4, filtered and rotovapped to give the crude methylated sulfonamide. By TLC the Rf values of the starting sulfonamide and the final product were identical, however the spots were different colors. Quick purification through a plug of Si02 with 30%-40% EtOAc in hexanes gave the desired product. (1. 88 g, 93 %) The nitrile (1 equiv, 8.94 mmol, 1.88 g) was dissolved in methanol, and N2 (g) was bubbled through the solution for 5 minutes before the addition of AcOH (1 equiv, 8.94 mmol, 0. 51 mL) and 5% DeGussa Pd/C (one scoop).

CHART U details a method for the preparation of ketones used in the invention. The preferred halogen is bromine or

iodine. A commercially available halogenated benzoate is coupled with (ot-ethoxyvinyl)-tributyl in the presence of a catalyst, for example a palladium catalyst like dichlorobis (triphenylphosphine) palladium, yielding a methylketone- substituted benzoate ester after hydrolytic workup. In a preferred embodiment of the invention, this reaction is conducted in an anhydrous organic solvent. In a further more preferred embodiment of the invention, this reaction is conducted in anhydrous toluene. (Kosugi and Migita, Bull. Chem.

Soc., Jpn. , 1987, 60, 767-768). Base-catalyzed nucleophilic addition to a stoichiometric excess of alkyl'-LG (or alkyl"- LG) yields a symmetric dialkylated productthat, depending on the strength of the base, may be directly converted to the equivalent benzoate. Alternatively, the methylketone- substituted benzoate ester may be reacted with a lower excess of alkyl'-LG, yielding a mono-substituted derivative. Said derivative may be further alkylated by base-catalyzed reaction with alkyl"-LG. It is understood that LG is Leaving Group as defined above. It is understood by one skilled in the art how to perform alkylations. In a preferred embodiment of the invention, said alkylations are catalyzed by sodium hydroxide or potassium hydroxide. In an additional preferred embodiment of the invention, the alkylations are conducted in a dipolar aprotic solvent, g.-dimethyl-sulfoxide.

Charts HH and II. Chart HH discloses the synthesis of a set of racemic a-amino sulfones while Chart II discloses the synthesis of the active enantiomer. The Michael addition of a thiol to a protected dehydroalanine methyl ester yields a sulfanyl intermediate. The sulfanyl derivative is peroxidated to the corresponding sulfone according to one of the above- mentioned methods. Hydrolysis of the ester and protecting group may be carried out with a strong aqueous acid, for example 6N HC1, or acetic acid, optionally at high temperature to yield the free amino acid salt. A protecting group for

example Cbz or Boc, may be added to the amine group. Standard peptide coupling to the unprotected diamine preferentially affords the product with an unreacted N-Rc moiety which is then orthogonally protected to yield the diprotected diamine.

Selective removal of the Rn protecting group affords a free amine. This amine can be converted according one of the above-mentioned methods into amides, carbamates,.

Alternatively, it may be reacted with an isocyanate to yield a urea, or with a sulfonyl chloride to yield a sulfonamide. The removal of the Rc protecting yields the targetcompounds. Chart II is identical to chart HH with an additional isomer separation step which may be carried out chemically, enzymatically, or by chiral chromatography, yielding the single isomer acid which is transformed into the target product as described above.

BIOLOGICAL EXAMPLES Example A Enzyme Inhibition Assay The compounds of the invention are analyzed for inhibitory activity by use of the MBP-C125 assay. This assay determines the relative inhibition of beta-secretase cleavage of a model APP substrate, MBP-C125SW, by the compounds assayed as compared with an untreated control. A detailed description of the assay parameters can be found, for example, in U. S.

Patent No. 5,942, 400. Briefly, the substrate is a fusion peptide formed of maltose binding protein (MBP) and the carboxy terminal 125 amino acids of APP-SW, the Swedish mutation. The beta-secretase enzyme is derived from human

brain tissue as described in Sinha et. al, 1999, Nature 40: 537- 540) or recombinantly produced as the full-length enzyme (amino acids 1-501), and can be prepared, for example, from 293 cells expressing the recombinant cDNA, as described in WOOO/47618.

Inhibition of the enzyme is analyzed, for example, by immunoassay of the enzyme's cleavage products. One exemplary ELISA uses an anti-MBP capture antibody that is deposited on precoated and blocked 96-well high binding plates, followed by incubation with diluted enzyme reaction supernatant, incubation with a specific reporter antibody, for example, biotinylated anti-SW192 reporter antibody, and further incubation with streptavidin/alkaline phosphatase. In the assay, cleavage of the intact MBP-C125SW fusion protein results in the generation of a truncated amino-terminal fragment, exposing a new SW-192 antibody-positive epitope at the carboxy terminus. Detection is effected by a fluorescent substrate signal on cleavage by the phosphatase. ELISA only detects cleavage following Leu 596 at the substrate's APP-SW 751 mutation site.

Specific Assay Procedure: Compounds are diluted in a 1: 1 dilution series to a six- point concentration curve (two wells per concentration) in one 96-plate row per compound tested. Each of the test compounds is prepared in DMSO to make up a 10 millimolar stock solution.

The stock solution is serially diluted in DMSO to obtain a final compound concentration of 200 micromolar at the high point of a 6-point dilution curve. Ten (10) microliters of each dilution is added to each of two wells on row C of a corresponding V-bottom plate to which 190 microliters of 52 millimolar NaOAc, 7. 9% DMSO, pH 4.5 are pre-added. The NaOAc diluted compound plate is spun down to pellet precipitant and 20 microliters/well is transferred to a corresponding flat- bottom plate to which 30 microliters of ice-cold enzyme-

substrate mixture (2.5 microliters MBP-C125SW substrate, 0. 03 microliters enzyme and 24.5 microliters ice cold 0. 09% TX100 per 30 microliters) is added. The final reaction mixture of 200 micromolar compound at the highest curve point is in 5% DMSO, 20 millimolar NaAc, 0.06% TX100, at pH 4.5.

Warming the plates to 37 degrees C starts the enzyme reaction. After 90 minutes at 37 degrees C, 200 microliters/well cold specimen diluent is added to stop the reaction and 20 microliters/well is transferred to a corresponding anti-MBP antibody coated ELISA plate for capture, containing 80 microliters/well specimen diluent.

This reaction is incubated overnight at 4 degrees C and the ELISA is developed the next day after a 2 hours incubation with anti-192SW antibody, followed by Streptavidin-AP conjugate and fluorescent substrate. The signal is read on a fluorescent plate reader.

Relative compound inhibition potency is determined by calculating the concentration of compound that showed a fifty percent reduction in detected signal (ICso) compared to the enzyme reaction signal in the control wells with no added compound. In this assay, the compounds of the invention exhibited an IC5o of less than or equal to 20 micromolar.

Example B Cell Free Inhibition Assay Utilizing a Synthetic APP Substrate A synthetic APP substrate that can be cleaved by beta- secretase and having N-terminal biotin and made fluorescent by the covalent attachment of oregon green at the Cys residue is used to assay beta-secretase activity in the presence or absence of the inhibitory compounds of the invention. Useful substrates include the following: Biotin-SEVNL-DAEFR [oregon green] KK [SEQ ID NO: 1]

Biotin-SEVKM-DAEFR [oregon green] KK [SEQ ID NO: 2] Biotin-GLNIKTEEISEISY-EVEFRC [oregon green] KK [SEQ ID NO: 3] Biotin-ADRGLTTRPGSGLTNIKTEEISEVNL-DAEF [oregon green] KK [SEQ ID NO : 4] Biotin-FVNQHLCoxGSHLVEALY-LVCoxGERGFFYTPKA [oregon green] KK [SEQ ID NO: 5] The enzyme (0. 1 nanomolar) and test compounds (0. 001- 100 micromolar) are incubated in pre-blocked, low affinity, black plates (384 well) at 37 degrees C for 30 minutes. The reaction is initiated by addition of 150 millimolar substrate to a final volume of 30 microliter per well. The final assay conditions are: 0. 001-100 micromolar compound inhibitor; 0. 1 molar sodium acetate (pH 4.5) ; 150 nanomolar substrate; 0. 1 nanomolar soluble beta-secretase ; 0. 001% Tween 20, and 2% DMSO. The assay mixture is incubated for 3 hours at 37 degrees C, and the reaction is terminated by the addition of a saturating concentration of immunopure streptavidin. After incubation with streptavidin at room temperature for 15 minutes, fluorescence polarization is measured, for example, using a LJL Acqurest (Ex485 nm/Em530 nm). The activity of the beta-secretase enzyme is detected by changes in the fluorescence polarization that occur when the substrate is cleaved by the enzyme. Incubation in the presence or absence of compound, inhibi. tor, demonstrates specific inhibition of beta-secretase enzymatic cleavage of its synthetic APP substrate. In this assay, compounds of the invention exhibited an IC50 of less than 20 micromolar.

Example C Beta-secretase inhibition : P26-P4'SW assay Synthetic substrates containing the beta-secretase cleavage site of APP are used to assay beta-secretase activity, using the methods described, for example, in

published PCT application WOOO/47618. The P26-P4'SW substrate is a peptide of the sequence: (biotin) CGGADRGLTTRPGSGLTNIKTEEISEVNLDAEF [SEQ ID NO : 6] The P26-P1 standard has the sequence: (biotin) CGGADRGLTTRPGSGLTNIKTEEISEVNL [SEQ ID NO : 7] Briefly, the biotin-coupled synthetic substrates are incubated at a concentration of from about 0 to about 200 micromolar in this assay. When testing inhibitory compounds, a substrate concentration of about 1.0 micromolar is preferred. Test compounds diluted in DMSO are added to the reaction mixture, with a final DMSO concentration of 5%.

Controls also contain a final DMSO concentration of 5%. The concentration of beta secretase enzyme in the reaction is varied, to give product concentrations with the linear range of the ELISA assay, about 125 to 2000 picomolar, after dilution.

The reaction mixture also includes 20 millimolar sodium acetate, pH 4.5, 0. 06% Triton X100, and is incubated at 37 degrees C for about 1 to 3 hours. Samples are then diluted in assay buffer (for example, 145.4 nanomolar sodium chloride, 9.51 millimolar sodium phosphate, 7.7 millimolar sodium azide, 0. 05% Triton X405,6g/liter bovine serum albumin, pH 7.4) to quench the reaction, then diluted further for immunoassay of the cleavage-products.

Cleavage products can be assayed by ELISA. Diluted samples and standards are incubated in assay plates coated with capture antibody, for example, SW192, for about 24 hours at 4 degrees C. After washing in TTBS buffer (150 millimolar sodium chloride, 25 millimolar Tris, 0.05% Tween 20, pH 7.5), the samples are incubated with strepavidin-AP according to the manufacturer's instructions. After a one hour incubation at room temperature, the samples are washed in TTBS and incubated with fluorescent substrate solution A (31.2 g/liter 2-amino-2- methyl-l-propanol, 30 mg/liter, pH 9.5). Reaction with

streptavidin-alkaline phosphate permits detection by fluorescence. Compounds that are effective inhibitors of beta-secretase activity demonstrate reduced cleavage of the substrate as compared to a control.

Example D Assays using Synthetic Oligopeptide-Substrates Synthetic oligopeptides are prepared that incorporate the known cleavage site of beta-secretase, and optionally detectable tags, such as fluorescent or chouromogenic moieties. Examples of such peptides, as well as their production and detection methods are described in U. S. Patent No: 5,942, 400, herein incorporated by reference. Cleavage products can be detected using high performance liquid chromatography, or fluorescent or chromogenic detection methods appropriate to the peptide to be detected, according to methods well known in the art.

By way of example, one such peptide has the sequence SEVNL- DAEF [SEQ ID NO : 8], and the cleavage site is between residues 5 and 6. Another preferred substrate has the sequence ADRGLTTRPGSGLTNIKTEEISEVNL-DAEF [SEQ ID NO : 9], and the cleavage site is between residues 26 and 27.

These synthetic APP substrates are incubated in the presence of beta-secretase under conditions sufficient to result in beta-secretase mediated cleavage of the substrate.

Comparison of the cleavage results in the presence of the compound inhibitor to control results provides a measure of the compound's inhibitory activity.

Example E Inhibition of beta-secretase activity-cellular assay

An exemplary assay for the analysis of inhibition of beta-secretase activity utilizes the human embryonic kidney cell line HEKp293 (ATCC Accession No. CRL-1573) transfected with APP751 containing the naturally occurring double mutation Lys651Met52 to Asn65lLeu652 (numbered for APP751), commonly called the Swedish mutation and shown to overproduce A beta (Citron et. al. , 1992, Nature 360: 672-674), as described in USPN 5,604, 102.

The cells are incubated in the presence/absence of the inhibitory compound (diluted in DMSO) at the desired concentration, generally up to 10 micrograms/ml. At the end of the treatment period, conditioned media is analyzed for beta-secretase activity, for example, by analysis of cleavage fragments. A beta can be analyzed by immunoassay, using specific detection antibodies. The enzymatic activity is measured in the presence and absence of the compound inhibitors to demonstrate specific inhibition of beta- secretase mediated cleavage of APP substrate.

Example F Inhibition of Beta-Secretase in Animal Models of AD Various animal models can be used to screen for inhibition of beta-secretase activity. Examples of animal models useful in the invention include, but are not limited to, mouse, guinea pig, dog, and the like. The animals used can be wild type, transgenic, or knockout models. In addition, mammalian models can express mutations in APP, such as APP695- SW and the like described herein. Examples of transgenic non-human mammalian models are described in U. S. Patent Nos.

5,604, 102,5, 912,410 and 5,811, 633.

PDAPP mice, prepared as described in Games et. al. , 1995, Nature 373: 523-527 are useful to analyze in vivo suppression of A beta release in the presence of putative inhibitory

compounds. As described in USPN 6,191, 166,4 month old PDAPP mice are administered compound formulated in vehicle, such as corn oil. The mice are dosed with compound (1-30 mg/ml ; preferably 1-10 mg/ml). After time, e. g. , 3-10 hours, the animals are sacrificed, and brains removed for analysis.

Transgenic animals are administered an amount of the compound inhibitor preferably formulated in a carrier suitable for the chosen mode of administration. Control animals are untreated, treated with vehicle, or treated with an inactive compound. Administration can be acute, i. e. , single dose or multiple doses in one day, or can be chronic, i. e. , dosing is repeated daily for a period of days. Beginning at time 0, brain tissue or cerebral fluid is obtained from selected animals and analyzed for the presence of APP cleavage peptides, including A beta, for example, by immunoassay using specific antibodies for A beta detection. At the end of the test period, animals are sacrificed and brain tissue or cerebral fluid is analyzed for the presence of A beta and/or beta-amyloid plaques. The tissue is also analyzed for necrosis.

Animals administered the compound inhibitors of the invention are expected to demonstrate reduced A beta in brain tissues or cerebral fluids and reduced beta amyloid plaques in braintissue, ascomparedwith non-treated controls.

Example G Inhibition of A beta production in human patients Patients suffering from Alzheimer's Disease (AD) demonstrate an increased amount of A beta in the brain. AD patients are administered an amount of the compound inhibitor formulated in a carrier suitable for the chosen mode of administration. Administration is repeated daily for the duration of the test period. Beginning on day 0, cognitive and memory tests are performed, for example, once per month.

Patients administered the compound inhibitors are expected to demonstrate slowing or stabilization of disease progression as analyzed by changes in one or more of the following disease parameters: A beta present in CSF or plasma ; brain or hippocampal volume ; A beta deposits in the brain; amyloid plaque in the brain; and scores for cognitive and memory function, as compared with control, non-treated patients.

Example H Prevention of A beta production in patients at risk for AD Patients predisposed or at risk for developing AD are identified either by recognition of a familial inheritance pattern, for example, presence of the Swedish Mutation, and/or by monitoring diagnostic parameters. Patients identified as predisposed or at risk for developing AD are administered an amount of the compound inhibitor preferably formulated in a carrier suitable for the chosen mode of administration.

Administration is repeated daily for the duration of the test period. Beginning on day 0, cognitive and memory tests are performed, for example, once per month.

Patients administered the compound inhibitors are expected to demonstrate slowing or stabilization of disease progression as analyzed by changes in one or more of the following disease parameters: A beta present in CSF or plasma; brain or hippocampal volume; amyloid plaque in the brain; and scores for cognitive and memory function, as compared with control, non-treated patients.
