Description:

RENIN INHIBITORS

FIELD OF THE INVENTION

[0001] The present invention relates to compounds that may be used to inhibit renin, as well as compositions of matter and kits comprising these compounds. The invention also relates to methods for inhibiting renin and treatment methods using compounds according to the present invention.

BACKGROUND OF THE INVENTION

[0002] The renin-angiotensin-aldosterone system ("RAAS") is one of the hormonal mechanisms involved in regulating pressure/volume homeostasis and also in the development of hypertension, a condition that can progress to more serious cardiovascular diseases such as congestive heart failure. Activation of RAAS begins with secretion of the enzyme renin from juxtaglomerular cells in the kidney.

[0003] Renin, a member of the aspartyl protease family, passes from the kidneys into the blood where it cleaves angiotensinogen to generate the decapeptide angiotensin I. Angiotensin I is then cleaved in the lungs, the kidneys and other organs by the angiotensin-converting enzyme (ACE) to form the octapeptide angiotensin II. Angiotensin II, which is known to work at least on two receptor subtypes (ATi and AT 2 ), increases blood pressure both directly by arterial vasoconstriction and indirectly by liberating from the adrenal glands the sodium-ion-retaining hormone aldosterone. Angiotensin II also produces other physiological effects such as promoting sodium and fluid retention, inhibiting renin secretion, increasing sympathetic nervous system activity, stimulating vasopressin secretion, causing a positive cardiac inotropic effect and modulating other hormonal systems.

[0004] Modulation of the RAAS represents a major advance in the treatment of cardiovascular diseases. In particular, the rationale to develop renin inhibitors lies in its specificity (Kleinert H. D., Cardiovasc. Drugs, 1995, 9, 645). The only substrate known for renin is angiotensinogen, which can only be processed (under physiological conditions) by renin. Inhibitors of the enzymatic activity of renin are therefore expected to bring about a reduction in the formation of angiotensin I and angiotensin II.

[0005] In view of the foregoing, renin is an especially attractive target for the discovery of new therapeutics for cardiovascular disease, hypertension, congestive heart failure, myocardial infarction, renal protection, inflammation, neurological diseases, cancer, and other diseases. Accordingly, there is a need to find new renin inhibitors for use as therapeutic agents to treat human diseases. In particular, there is a continued need for metabolically stable, orally bioavailable renin inhibitors that can be prepared on a large scale.

[0006] Modeling of the active site of renin has now revealed that certain classes of known compounds, including those described in US 2005/072765 Al US 2006/014764 Al, WO 2005/118555 and WO 2006/020017, may also possess renin activity. Those compounds were previously reported to be DPP-IV inhibitors, but they have now proven to be useful leads in the search for renin inhibitors.

Stereoisomers that are not mirror images of one another are termed "diastereomers" and stereoisomers that are nonsuperimposable mirror images are termed "enantiomers" or sometimes "optical isomers." A carbon atom bonded to four nonidentical substituents is termed a "chiral center." A compound with one chiral center has two enantiomeric forms of opposite chirality. A mixture of the two enantiomeric forms is termed a "racemic mixture." A compound that has more than one chiral center has 2 enantiomeric pairs, where n is the number of chiral centers.

Absolute configuration refers to the arrangement in space of the substituents attached to the chiral center. Enantiomers are characterized by the absolute configuration of their chiral centers and described by the R- and ^-sequencing rules of Cahn, Ingold and Prelog. Conventions for stereochemical nomenclature, methods for the determination of stereochemistry and the separation of stereoisomers are well known in the art (e.g. , see "Advanced Organic Chemistry", 5th edition, March, Jerry, John Wiley & Sons, New York, 2001).

Salts, Hydrates, and Prodrugs of Renin Inhibitors

[0177] It should be recognized that the compounds of the present invention may be present and optionally administered in the form of salts, hydrates and prodrugs that are converted in vivo into the compounds of the present invention. For example, it is within the scope of the present invention to convert the compounds of the present invention into and use them in the form of their pharmaceutically acceptable salts derived from various organic and inorganic acids and bases in accordance with procedures well known in the art.

[0178] A "pharmaceutically acceptable salt", as used herein, is intended to encompass any compound according to the present invention that is utilized in the form of a salt thereof, especially where the salt confers on the compound improved pharmacokinetic properties as compared to the free form of compound or a different salt form of the compound. The pharmaceutically acceptable salt form may also initially confer desirable pharmacokinetic properties on the compound that it did not previously possess, and may even positively affect the pharmacodynamics of the compound with respect to its therapeutic activity in the body. An example of a pharmacokinetic property that may be favorably affected is the manner in which the compound is transported across cell membranes, which in turn may directly and positively affect the absorption, distribution, biotransformation and excretion of the compound. While the route of administration of the pharmaceutical composition is important, and various anatomical, physiological and pathological factors can critically affect bioavailability, the solubility of the compound is usually dependent upon the character of the particular salt form thereof, which it utilized. One of skill in the art will appreciate that an aqueous solution of the compound will provide the most rapid absorption of the compound into the body of a subject being

treated, while lipid solutions and suspensions, as well as solid dosage forms, will result in less rapid absorption of the compound.

[0179] When the compounds of the present invention possess a free base form, the compounds can be prepared as a pharmaceutically acceptable acid addition salt by reacting the free base form of the compound with a pharmaceutically acceptable inorganic or organic acid, e.g., hydrohalides such as hydrochloride, hydrobromide, hydroiodide; other mineral acids and their corresponding salts such as sulfate, nitrate, phosphate, etc.; and alkyl and monoarylsulfonates such as ethanesulfonate, toluenesulfonate and benzenesulfonate; and other organic acids and their corresponding salts such as acetate, tartrate, maleate, succinate, citrate, benzoate, salicylate and ascorbate. Further acid addition salts of the present invention include, but are not limited to: adipate, alginate, arginate, aspartate, bisulfate, bisulfite, bromide, butyrate, camphorate, camphorsulfonate, caprylate, chloride, chlorobenzoate, cyclopentanepropionate, digluconate, dihydrogenphosphate, dinitrobenzoate, dodecylsulfate, fumarate, galacterate (from mucic acid), galacturonate, glucoheptonate, gluconate, glutamate, glycerophosphate, hemisuccinate, hemisulfate, heptanoate, hexanoate, hippurate, hydrochloride, hydrobromide, hydroiodide, 2-hydroxyethanesulfonate, iodide, isethionate, iso-butyrate, lactate, lactobionate, malate, malonate, mandelate, metaphosphate, methanesulfonate, methylbenzoate, monohydrogenphosphate, 2-naphthalenesulfonate, nicotinate, nitrate, oxalate, oleate, pamoate, pectinate, persulfate, phenylacetate, 3-phenylpropionate, phosphate, phosphonate and phthalate. It should be recognized that the free base forms will typically differ from their respective salt forms somewhat in physical properties such as solubility in polar solvents, but otherwise the salts are equivalent to their respective free base forms for the purposes of the present invention.

[0180] When the compounds of the present invention possess a free acid form, a pharmaceutically acceptable base addition salt can be prepared by reacting the free acid form of the compound with a pharmaceutically acceptable inorganic or organic base. Examples of such bases are alkali metal hydroxides including potassium, sodium and lithium hydroxides; alkaline earth metal hydroxides such as barium and calcium hydroxides; alkali metal alkoxides, e.g., potassium ethanolate and sodium propanolate; and various organic bases such as ammonium hydroxide, piperidine, diethanolamine and JV-methylglutamine. Also included are the aluminum salts of the compounds of the

present invention. Further base salts of the present invention include, but are not limited to: copper, ferric, ferrous, lithium, magnesium, manganic, manganous, potassium, sodium and zinc salts. Organic base salts include, but are not limited to, salts of primary, secondary and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines and basic ion exchange resins, e.g., arginine, betaine, caffeine, chloroprocaine, choline, λ/.iV'-dibenzylethylenediamine (benzathine), dicyclohexylamine, diethanolamine, 2-diethylaminoethanol, 2-dimethylaminoethanol, ethanolamine, ethylenediamine, JV-ethylmorpholine, λ/-ethylpiperidine, glucamine, glucosamine, histidine, hydrabamine, iso-propylamine, lidocaine, lysine, meglumine, JV-methyl-D- glucamine, morpholine, piperazine, piperidine, polyamine resins, procaine, purines, theobromine, triethanolamine, triethylamine, trimethylamine, tripropylamine and tris- (hydroxymethyl)-methylamine (tromethamine). It should be recognized that the free acid forms will typically differ from their respective salt forms somewhat in physical properties such as solubility in polar solvents, but otherwise the salts are equivalent to their respective free acid forms for the purposes of the present invention. [0181] The present invention also encompasses quaternally ammonium salts for the compounds of the present invention comprising basic nitrogen containing groups. The quaternally ammonium salts include, but are not limited to, those that be quaternized with such agents as (C 1-4 ) alkyl halides, e.g., methyl, ethyl, iso-propyl and tert-butyl chlorides, bromides and iodides; di (C 1-4 ) alkyl sulfates, e.g., dimethyl, diethyl and diamyl sulfates; (C 10-18 ) alkyl halides, e.g., decyl, dodecyl, lauryl, myristyl and stearyl chlorides, bromides and iodides; and aryl (Ci -4 ) alkyl halides, e.g., benzyl chloride and phenethyl bromide. Such salts permit the preparation of both water-soluble and oil-soluble compounds of the present invention.

[0182] The present invention also encompasses iV-oxides of compounds according to the present invention. The iV-oxides can be prepared by methods known to those of ordinary skill in the art. For example, TV-oxides can be prepared by treating an unoxidized form of the compound with an oxidizing agent (e.g., trifluoroperacetic acid, permaleic acid, perbenzoic acid, peracetic acid, meta-chloroperoxybenzoic acid, or the like) in a suitable inert organic solvent (e.g. , a halogenated hydrocarbon such as dichloromethane) at approximately 0 0 C. Alternatively, the λ/-oxides of the compounds can be prepared from the N-oxide of an appropriate starting material.

[0183] Compounds of the invention further include prodrug derivatives of the compounds. It is noted that in many instances, the prodrugs themselves also fall within the scope of the range of compounds according to the present invention. Pharmaceutically acceptable prodrugs of the compounds of this invention include, but are not limited to, esters, carbonates, thiocarbonates, N-acyl derivatives, N-acyloxyalkyl derivatives, quaternary derivatives of tertiary amines, N-Mannich bases, Schiff bases, amino acid conjugates, phosphate esters, metal salts, sulfonate esters, and other Prodrug forms that are well known in the art. For examples of such prodrug derivatives, see, e.g., a) DESIGN OF PRODRUGS, Bundgaard, A. Ed., 1985, Elsevier; b) Bundgaard, H. Design and Application of Prodrugs in A TEXTBOOK OF DRUG DESIGN AND DEVELOPMENT, Krosgaard-Larsen and H.

[0184] The invention further includes solvates and hydrates of the compounds of the invention. The solvates and hydrates may be formed during the process of the preparation or may be conveniently prepared by recrystallization from an aqueous/organic solvent mixture, using organic solvents such as dioxin, tetrahydrofuran or methanol.

Uses of the Renin Inhibitors

[0185] Renin inhibitors of the present invention may be used to treat and/or prevent high blood pressure, cardiovascular diseases, congestive heart failure, myocardial infarction, renal protection, inflammation, neurological disease and cancer. [0186] Renin is a proteolytic enzyme synthesized and stored principally in the juxtaglomerular apparatus. When renin is released into the blood from the kidney, the renin-angiotensin-aldosterone system ("RAAS") is activated. Renin acts on the alpha-2 globulin angiotensinogen (synthesized in the liver) to generate angiotensin I. This non- pressor decapeptide is converted to angiotensin II by angiotensin-converting enzyme

(ACE). The major pharmacological effects of angiotensin II are vasoconstriction and stimulation of the adrenal cortex to release aldosterone, a hormone which causes sodium retention. Vasoconstriction and conservation of sodium both contribute to increased blood pressure. Angiotensin II also produces other physiological effects such as inhibiting renin secretion, increasing sympathetic nervous system activity, stimulating vasopressin secretion, causing a positive cardiac inotropic effect and modulating other hormonal systems. Thus, the renin-angiotensin system plays an important role in normal cardiovascular homeostasis and in some forms of elevated blood pressure (hypertension). [0187] The reduction of the activity of renin in a subject through inhibition may therefore be used to therapeutically address the diseases and conditions caused by the overactivation of RAAS.

[0188] Thus, renin inhibiting compounds of the present invention may be used as agents for control of hypertension, may also be used to treat and/or prevent congestive heart failure and hyperaldosteronism, vascular diseases related to diabetes, and renal diseases such as acute or chronic renal failure. In addition, the renin inhibiting compounds may also be used as diagnostic agents for identification of cases of hypertension due to renin excess.

[0189] It is noted that the compounds of the present invention may also possess inhibitory activity for other aspartyl proteases (e.g., pepsin, gastricsin, napsin, BACE 1 & 2 and cathepsin D and E) and thus may be used to address disease states associated with these other family members.

[0190] In addition, the compounds of the present invention may be useful as inhibitors of plasmepsins to treat malaria and as inhibitors of Candida albicans secreted aspartyl proteases to treat fungal infections.

[0191] It is further noted that additional diseases beyond those disclosed herein may also be identified as the biological roles that renin and the RAAS system play in various pathways become more fully understood.

[0192] It is further noted that the compounds of the present invention may be useful as inhibitors of dipeptidyl peptidase IV (DPP-IV) to treat diseases and conditions associate with type II diabetes.

Combination Therapy

[0193] A wide variety of therapeutic agents may have a therapeutic additive or synergistic effect when used in combination with renin inhibitors according to the present invention. Such therapeutic agents may additively or synergistically combine with the renin inhibitors to reduce or alleviate the effects and symptoms of cardiovascular disease. [0194] The compounds according to the present invention may be used in combination with other therapeutic agents, wherein the cells are treated with a compound according to the present invention before, at the same time, and/or after the cells are treated with the one or more additional cardiovascular therapeutics; these treatments are referred to herein as combination therapy. It is noted that administration of one agent before another is referred to herein as sequential therapy, even if the agents are also administered together. It is noted that combination therapy is intended to cover methods where agents are administered before or after each other (sequential therapy) as well as when the agents are administered at the same time.

[0195] Representative classes of cardiovascular agents that may be used with the renin inhibitors of the present invention include, but are not limited to, diuretics, adrenergic blocking agents, vasodilators, calcium channel blockers, angiotensin converting enzyme (ACE) inhibitors, potassium channel activators, antiserotoninergic agents, thromboxane synthetase inhibitors, angiotensin II antagonists, angiotensin II receptor blockers, and other agents useful for treating (in a human or other mammal) hypertension, congestive heart failure, or vascular diseases related to diabetes, or for treating renal diseases such as acute or chronic renal failure.

Dosage, Host and Safety

[0206] The compounds of the present invention are stable and can be used safely. In particular, the compounds of the present invention are useful as renin inhibitors for a variety of subjects (e.g., humans, non-human mammals and non-mammals). The optimal dose may vary depending upon such conditions as, for example, the type of subject, the body weight of the subject, the route of administration, and specific properties of the particular compound being used. In general, the daily dose for oral administration to an adult (body weight of about 60 kg) is about 1 to 1000 mg, about 3 to 300 mg, or about 10 to 200 mg. It will be appreciated that the daily dose can be given in a single administration or in multiple (e.g., 2 or 3) portions a day.

Compositions Comprising Renin Inhibitors

[0207] A wide variety of compositions and administration methods may be used in conjunction with the present invention. Such compositions may include, in addition to the compounds of the present invention, conventional pharmaceutical excipients, and other conventional, pharmaceutically inactive agents. Additionally, the compositions may include active agents in addition to the compounds of the present invention. These additional active agents may include additional compounds according to the invention, and/or one or more other pharmaceutically active agents.

[0208] The compositions may be in gaseous, liquid, semi-liquid or solid form, formulated in a manner suitable for the route of administration to be used. For oral administration, capsules and tablets are typically used. For parenteral administration, reconstitution of a lyophilized powder, prepared as described herein, is typically used. [0209] Compositions comprising compounds of the present invention may be administered or coadministered orally, parenterally, intraperitoneally, intravenously, intraarterially, transdermally, sublingually, intramuscularly, rectally, transbuccally, intranasally, liposomally, via inhalation, vaginally, intraoccularly, via local delivery (for example by catheter or stent), subcutaneously, intraadiposally, intraarticularly, or intrathecally. The compounds and/or compositions according to the invention may also be administered or coadministered in slow release dosage forms.

[0210] The renin inhibitors and compositions comprising them may be administered or coadministered in any conventional dosage form. Co-administration in the context of this invention is intended to mean the administration of more than one therapeutic agent, one of which includes a renin inhibitor, in the course of a coordinated treatment to achieve an improved clinical outcome. Such co-administration may also be coextensive, that is, occurring during overlapping periods of time.

[0211] Solutions or suspensions used for parenteral, intradermal, subcutaneous, or topical application may optionally include one or more of the following components: a sterile diluent, such as water for injection, saline solution, fixed oil, polyethylene glycol, glycerine, propylene glycol or other synthetic solvent; antimicrobial agents, such as benzyl alcohol and methyl parabens; antioxidants, such as ascorbic acid and sodium bisulfite; chelating agents, such as ethylenediaminetetraacetic acid (EDTA); buffers, such as acetates, citrates and phosphates; agents for the adjustment of tonicity such as sodium

chloride or dextrose, and agents for adjusting the acidity or alkalinity of the composition, such as alkaline or acidifying agents or buffers like carbonates, bicarbonates, phosphates, hydrochloric acid, and organic acids like acetic and citric acid. Parenteral preparations may optionally be enclosed in ampules, disposable syringes or single or multiple dose vials made of glass, plastic or other suitable material.

[0212] When compounds for use with the present invention exhibit insufficient solubility, methods for solubilizing the compounds may be used. Such methods are known to those of skill in this art, and include, but are not limited to, using cosolvents, such as dimethylsulfoxide (DMSO), using surfactants, such as TWEEN, or dissolution in aqueous sodium bicarbonate. Derivatives of the compounds, such as prodrugs of the compounds may also be used in formulating effective pharmaceutical compositions. [0213] Upon mixing or adding compounds for use with the present invention to a composition, a solution, suspension, emulsion or the like may be formed. The form of the resulting composition will depend upon a number of factors, including the intended mode of administration, and the solubility of the compound in the selected carrier or vehicle. The effective concentration needed to ameliorate the disease being treated may be empirically determined.

[0214] Compositions according to the present invention are optionally provided for administration to humans and animals in unit dosage forms, such as tablets, capsules, pills, powders, dry powders for inhalers, granules, sterile parenteral solutions or suspensions, and oral solutions or suspensions, and oil-water emulsions containing suitable quantities of the compounds, particularly the pharmaceutically acceptable salts, preferably the sodium salts, thereof. The pharmaceutically therapeutically active compounds and derivatives thereof are typically formulated and administered in unit-dosage forms or multiple-dosage forms. Unit-dose forms, as used herein, refers to physically discrete units suitable for human and animal subjects and packaged individually as is known in the art. Each unit- dose contains a predetermined quantity of the therapeutically active compound sufficient to produce the desired therapeutic effect, in association with the required pharmaceutical carrier, vehicle or diluent. Examples of unit-dose forms include ampoules and syringes individually packaged tablet or capsule. Unit-dose forms may be administered in fractions or multiples thereof. A multiple-dose form is a plurality of identical unit-dosage forms packaged in a single container to be administered in segregated unit-dose form. Examples

of multiple-dose forms include vials, bottles of tablets or capsules or bottles of pint or gallons. Hence, multiple dose form is a multiple of unit-doses that are not segregated in packaging.

[0215] In addition to one or more compounds according to the present invention, the composition may comprise: a diluent such as lactose, sucrose, dicalcium phosphate, or carboxymethylcellulose; a lubricant, such as magnesium stearate, calcium stearate and talc; and a binder such as starch, natural gums, such as gum acacia gelatin, glucose, molasses, polvinylpyrrolidine, celluloses and derivatives thereof, povidone, crospovidones and other such binders known to those of skill in the art. Liquid pharmaceutically administrable compositions can, for example, be prepared by dissolving, dispersing, or otherwise mixing an active compound as defined above and optional pharmaceutical adjuvants in a carrier, such as, for example, water, saline, aqueous dextrose, glycerol, glycols, ethanol, and the like, to form a solution or suspension. If desired, the pharmaceutical composition to be administered may also contain minor amounts of auxiliary substances such as wetting agents, emulsifying agents, or solubilizing agents, pH buffering agents and the like, for example, acetate, sodium citrate, cyclodextrine derivatives, sorbitan monolaurate, triethanolamine sodium acetate, triethanolamine oleate, and other such agents. Actual methods of preparing such dosage forms are known in the art, or will be apparent, to those skilled in this art; for example, see Remington's Pharmaceutical Sciences, Mack Publishing Company, Easton, Pa., 15th Edition, 1975. The composition or formulation to be administered will, in any event, contain a sufficient quantity of an inhibitor of the present invention to reduce renin activity in vivo, thereby treating the disease state of the subject.

[0216] Dosage forms or compositions may optionally comprise one or more compounds according to the present invention in the range of 0.005% to 100% (weight/weight) with the balance comprising additional substances such as those described herein. For oral administration, a pharmaceutically acceptable composition may optionally comprise any one or more commonly employed excipients, such as, for example pharmaceutical grades of mannitol, lactose, starch, magnesium stearate, talcum, cellulose derivatives, sodium crosscarmellose, glucose, sucrose, magnesium carbonate, sodium saccharin, talcum. Such compositions include solutions, suspensions, tablets, capsules, powders, dry powders for inhalers and sustained 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 others. Methods for preparing these formulations are known to those skilled in the art. The compositions may optionally contain 0.01%-100% (weight/weight) of one or more renin inhibitors, optionally 0.1-95%, and optionally 1-95%.

[0217] Salts, preferably sodium salts, of the inhibitors may be prepared with carriers that protect the compound against rapid elimination from the body, such as time release formulations or coatings. The formulations may further include other active compounds to obtain desired combinations of properties.

A. Formulations for Oral Administration

[0234] The compounds of the present invention may also be mixed with other active materials that do not impair the desired action, or with materials that supplement the desired action, such as antacids, H2 blockers, and diuretics. For example, if a compound is used for treating asthma or hypertension, it may be used with other bronchodilators and antihypertensive agents, respectively.

[0235] Examples of pharmaceutically acceptable carriers that may be included in tablets comprising compounds of the present invention include, but are not limited to binders, lubricants, diluents, disintegrating agents, coloring agents, flavoring agents, and wetting agents. Enteric-coated tablets, because of the enteric-coating, resist the action of stomach acid and dissolve or disintegrate in the neutral or alkaline intestines. Sugar- coated tablets may be compressed tablets to which different layers of pharmaceutically acceptable substances are applied. Film-coated tablets may be compressed tablets that have been coated with polymers or other suitable coating. Multiple compressed tablets may be compressed tablets made by more than one compression cycle utilizing the pharmaceutically acceptable substances previously mentioned. Coloring agents may also be used in tablets. Flavoring and sweetening agents may be used in tablets, and are especially useful in the formation of chewable tablets and lozenges. [0236] Examples of liquid oral dosage forms that may be used include, but are not limited to, aqueous solutions, emulsions, suspensions, solutions and/or suspensions reconstituted from non-effervescent granules and effervescent preparations reconstituted from effervescent granules.

[0237] Examples of aqueous solutions that may be used include, but are not limited to, elixirs and syrups. As used herein, elixirs refer to clear, sweetened, hydroalcoholic preparations. Examples of pharmaceutically acceptable carriers that may be used in elixirs include, but are not limited to solvents. Particular examples of solvents that may be used include glycerin, sorbitol, ethyl alcohol and syrup. As used herein, syrups refer to concentrated aqueous solutions of a sugar, for example, sucrose. Syrups may optionally further comprise a preservative.

[0238] Emulsions refer to two-phase systems in which one liquid is dispersed in the form of small globules throughout another liquid. Emulsions may optionally be oil-in- water or water-in-oil emulsions. Examples of pharmaceutically acceptable carriers that may be used in emulsions include, but are not limited to non-aqueous liquids, emulsifying agents and preservatives.

[0239] Examples of pharmaceutically acceptable substances that may be used in non- effervescent granules, to be reconstituted into a liquid oral dosage form, include diluents, sweeteners and wetting agents.

[0240] Examples of pharmaceutically acceptable substances that may be used in effervescent granules, to be reconstituted into a liquid oral dosage form, include organic acids and a source of carbon dioxide.

[0241] Coloring and flavoring agents may optionally be used in all of the above dosage forms.

[0249] Particular examples of flavoring agents that may be used include natural flavors extracted from plants such fruits, and synthetic blends of compounds that produce a pleasant taste sensation.

[0250] For a solid dosage form, the solution or suspension, in for example propylene carbonate, vegetable oils or triglycerides, is preferably encapsulated in a gelatin capsule. Such solutions, and the preparation and encapsulation thereof, are disclosed in U.S. Pat. Nos. 4,328,245; 4,409,239; and 4,410,545. For a liquid dosage form, the solution, e.g., for example, in a polyethylene glycol, may be diluted with a sufficient quantity of a pharmaceutically acceptable liquid carrier, e.g., water, to be easily measured for administration.

[0251] Alternatively, liquid or semi-solid oral formulations may be prepared by dissolving or dispersing the active compound or salt in vegetable oils, glycols, triglycerides, propylene glycol esters (e.g., propylene carbonate) and other such carriers, and encapsulating these solutions or suspensions in hard or soft gelatin capsule shells. Other useful formulations include those set forth in U.S. Pat. Nos. Re 28,819 and 4,358,603.

B. Injectables, Solutions, and Emulsions

[0252] The present invention is also directed to compositions designed to administer the compounds of the present invention by parenteral administration, generally characterized by subcutaneous, intramuscular or intravenous injection. Injectables may be prepared in any conventional form, for example as liquid solutions or suspensions, solid forms suitable for solution or suspension in liquid prior to injection, or as emulsions. [0253] Examples of excipients that may be used in conjunction with injectables according to the present invention include, but are not limited to water, saline, dextrose, glycerol or ethanol. The injectable compositions may also optionally comprise minor amounts of non-toxic auxiliary substances such as wetting or emulsifying agents, pH buffering agents, stabilizers, solubility enhancers, and other such agents, such as for example, sodium acetate, sorbitan monolaurate, triethanolamine oleate and cyclodextrins. Implantation of a slow-release or sustained-release system, such that a constant level of dosage is maintained (see, e.g., U.S. Pat. No. 3,710,795) is also contemplated herein. The percentage of active compound contained in such parenteral compositions is highly

dependent on the specific nature thereof, as well as the activity of the compound and the needs of the subject.

[0254] Parenteral administration of the formulations includes intravenous, subcutaneous and intramuscular administrations. Preparations for parenteral administration include sterile solutions ready for injection, sterile dry soluble products, such as the lyophilized powders described herein, ready to be combined with a solvent just prior to use, including hypodermic tablets, sterile suspensions ready for injection, sterile dry insoluble products ready to be combined with a vehicle just prior to use and sterile emulsions. The solutions may be either aqueous or nonaqueous.

[0255] When administered intravenously, examples of suitable carriers include, but are not limited to physiological saline or phosphate buffered saline (PBS), and solutions containing thickening and solubilizing agents, such as glucose, polyethylene glycol, and polypropylene glycol and mixtures thereof.

[0256] Examples of pharmaceutically acceptable carriers that may optionally be used in parenteral preparations include, but are not limited to aqueous vehicles, nonaqueous vehicles, antimicrobial agents, isotonic agents, buffers, antioxidants, local anesthetics, suspending and dispersing agents, emulsifying agents, sequestering or chelating agents and other pharmaceutically acceptable substances.

[0257] Examples of aqueous vehicles that may optionally be used include Sodium

Chloride Injection, Ringers Injection, Isotonic Dextrose Injection, Sterile Water Injection,

Dextrose and Lactated Ringers Injection.

[0258] Examples of nonaqueous parenteral vehicles that may optionally be used include fixed oils of vegetable origin, cottonseed oil, corn oil, sesame oil and peanut oil.

[0259] Antimicrobial agents in bacteriostatic or fungistatic concentrations may be added to parenteral preparations, particularly when the preparations are packaged in multiple-dose containers and thus designed to be stored and multiple aliquots to be removed. Examples of antimicrobial agents that may be used include phenols or cresols, mercurials, benzyl alcohol, chlorobutanol, methyl and propyl p-hydroxybenzoic acid esters, thimerosal, benzalkonium chloride and benzethonium chloride.

[0260] Examples of isotonic agents that may be used include sodium chloride and dextrose. Examples of buffers that may be used include phosphate and citrate. Examples of antioxidants that may be used include sodium bisulfate. Examples of local anesthetics

that may be used include procaine hydrochloride. Examples of suspending and dispersing agents that may be used include sodium carboxymethylcellulose, hydroxypropyl methylcellulose and polyvinylpyrrolidone. Examples of emulsifying agents that may be used include Polysorbate 80 (TWEEN 80). A sequestering or chelating agent of metal ions includes EDTA.

[0261] Pharmaceutical carriers may also optionally include ethyl alcohol, polyethylene glycol and propylene glycol for water miscible vehicles and sodium hydroxide, hydrochloric acid, citric acid or lactic acid for pH adjustment.

[0262] The concentration of an inhibitor in the parenteral formulation may be adjusted so that an injection administers a pharmaceutically effective amount sufficient to produce the desired pharmacological effect. The exact concentration of an inhibitor and/or dosage to be used will ultimately depend on the age, weight and condition of the patient or animal as is known in the art.

[0263] Unit-dose parenteral preparations may be packaged in an ampoule, a vial or a syringe with a needle. All preparations for parenteral administration should be sterile, as is known and practiced in the art.

[0264] Injectables may be designed for local and systemic administration. Typically a therapeutically effective dosage is formulated to contain a concentration of at least about 0.1% w/w up to about 90% w/w or more, preferably more than 1% w/w of the renin inhibitor to the treated tissue(s). The inhibitor 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 will be a function of the location of where the composition is parenterally administered, the carrier and other variables that 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 age of the individual treated. It is to be further understood that for any particular subject, specific dosage regimens may need to be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the formulations. Hence, the concentration ranges set forth herein are intended to be exemplary and are not intended to limit the scope or practice of the claimed formulations.

[0265] The renin inhibitor may optionally be suspended in micronized or other suitable form or may be derivatized to produce a more soluble active product or to produce a prodrug. 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 effective concentration is sufficient for ameliorating the symptoms of the disease state and may be empirically determined.

C. Lyophilized Powders

[0266] The compounds of the present invention may also be prepared as lyophilized powders, which can be reconstituted for administration as solutions, emulsions and other mixtures. The lyophilized powders may also be formulated as solids or gels. [0267] Sterile, lyophilized powder may be prepared by dissolving the compound in a sodium phosphate buffer solution containing dextrose or other suitable excipient. Subsequent sterile filtration of the solution followed by lyophilization under standard conditions known to those of skill in the art provides the desired formulation. Briefly, the lyophilized powder may optionally be prepared by dissolving dextrose, sorbitol, fructose, corn syrup, xylitol, glycerin, glucose, sucrose or other suitable agent, about 1-20%, preferably about 5 to 15%, in a suitable buffer, such as citrate, sodium or potassium phosphate or other such buffer known to those of skill in the art at, typically, about neutral pH. Then, a renin inhibitor is added to the resulting mixture, preferably above room temperature, more preferably at about 30-35 0 C, and stirred until it dissolves. The resulting mixture is diluted by adding more buffer to a desired concentration. The resulting mixture is sterile filtered or treated to remove particulates and to insure sterility, and apportioned into vials for lyophilization. Each vial may contain a single dosage or multiple dosages of the inhibitor.

D. Formation for Topical Administration

[0268] The compounds of the present invention may also be administered as topical mixtures. Topical mixtures may be used for local and systemic administration. The resulting mixture may be a solution, suspension, emulsions or the like and are formulated as creams, gels, ointments, emulsions, solutions, elixirs, lotions, suspensions, tinctures, pastes, foams, aerosols, irrigations, sprays, suppositories, bandages, dermal patches or any other formulations suitable for topical administration.

[0269] The renin inhibitors may be formulated as aerosols for topical application, such as by inhalation (see, U.S. Pat. Nos. 4,044,126, 4,414,209, and 4,364,923, which describe aerosols for delivery of a steroid useful for treatment of inflammatory diseases, particularly asthma). These formulations for administration to the respiratory tract can be in the form of an aerosol or solution for a nebulizer, or as a microfme powder for insufflation, alone or in combination with an inert carrier such as lactose. In such a case, the particles of the formulation will typically have diameters of less than 50 microns, preferably less than 10 microns.

[0270] The inhibitors may also be formulated for local or topical application, such as for topical application to the skin and mucous membranes, such as in the eye, in the form of gels, creams, and lotions and for application to the eye or for intracisternal or intraspinal application. Topical administration is contemplated for transdermal delivery and also for administration to the eyes or mucosa, or for inhalation therapies. Nasal solutions of the renin inhibitor alone or in combination with other pharmaceutically acceptable excipients can also be administered.

E. Formulations for Other Routes of Administrations

[0271] Depending upon the disease state being treated, other routes of administration, such as topical application, transdermal patches, and rectal administration, may also be used. For example, pharmaceutical dosage forms for rectal administration are rectal suppositories, capsules and tablets for systemic effect. Rectal suppositories are used herein mean solid bodies for insertion into the rectum that melt or soften at body temperature releasing one or more pharmacologically or therapeutically active ingredients. Pharmaceutically acceptable substances utilized in rectal suppositories are bases or vehicles and agents to raise the melting point. Examples of bases include cocoa butter (theobroma oil), glycerin-gelatin, carbowax, (polyoxyethylene glycol) and appropriate mixtures of mono-, di- and triglycerides of fatty acids. Combinations of the various bases may be used. Agents to raise the melting point of suppositories include spermaceti and wax. Rectal suppositories may be prepared either by the compressed method or by molding. The typical weight of a rectal suppository is about 2 to 3 gm. Tablets and capsules for rectal administration may be manufactured using the same pharmaceutically acceptable substance and by the same methods as for formulations for oral administration.

F. Examples of Formulations

[0272] The following are particular examples of oral, intravenous and tablet formulations that may optionally be used with compounds of the present invention.

Kits and Articles of Manufacture Comprising Renin Inhibitors

[0273] The invention is also directed to kits and other articles of manufacture for treating diseases associated with renin. It is noted that diseases are intended to cover all conditions for which the renin possess activity that contributes to the pathology and/or symptomology of the condition.

[0274] In one embodiment, a kit is provided that comprises a composition comprising at least one inhibitor of the present invention in combination with instructions. The instructions may indicate the disease state for which the composition is to be administered, storage information, dosing information and/or instructions regarding how to administer the composition. The kit may also comprise packaging materials. The packaging material may comprise a container for housing the composition. The kit may also optionally comprise additional components, such as syringes for administration of the composition. The kit may comprise the composition in single or multiple dose forms.

[0275] In another embodiment, an article of manufacture is provided that comprises a composition comprising at least one inhibitor of the present invention in combination with packaging materials. The packaging material may comprise a container for housing the composition. The container may optionally comprise a label indicating the disease state for which the composition is to be administered, storage information, dosing information and/or instructions regarding how to administer the composition. The kit may also optionally comprise additional components, such as syringes for administration of the composition. The kit may comprise the composition in single or multiple dose forms. [0276] It is noted that the packaging material used in kits and articles of manufacture according to the present invention may form a plurality of divided containers such as a divided bottle or a divided foil packet. The container can be in any conventional shape or form as known in the art which is made of a pharmaceutically acceptable material, for example a paper or cardboard box, a glass or plastic bottle or jar, a re-sealable bag (for example, to hold a "refill" of tablets for placement into a different container), or a blister pack with individual doses for pressing out of the pack according to a therapeutic schedule. The container that is employed will depend on the exact dosage form involved, for example a conventional cardboard box would not generally be used to hold a liquid suspension. It is feasible that more than one container can be used together in a single package to market a single dosage form. For example, tablets may be contained in a bottle that is in turn contained within a box. Typically the kit includes directions for the administration of the separate components. The kit form is particularly advantageous when the separate components are preferably administered in different dosage forms (e.g., oral, topical, transdermal and parenteral), are administered at different dosage intervals, or when titration of the individual components of the combination is desired by the prescribing physician.

[0277] One particular example of a kit according to the present invention is a so-called blister pack. Blister packs are well known in the packaging industry and are being widely used for the packaging of pharmaceutical unit dosage forms (tablets, capsules, and the like). Blister packs generally consist of a sheet of relatively stiff material covered with a foil of a preferably transparent plastic material. During the packaging process recesses are formed in the plastic foil. The recesses have the size and shape of individual tablets or capsules to be packed or may have the size and shape to accommodate multiple tablets

and/or capsules to be packed. Next, the tablets or capsules are placed in the recesses accordingly and the sheet of relatively stiff material is sealed against the plastic foil at the face of the foil which is opposite from the direction in which the recesses were formed. As a result, the tablets or capsules are individually sealed or collectively sealed, as desired, in the recesses between the plastic foil and the sheet. Preferably the strength of the sheet is such that the tablets or capsules can be removed from the blister pack by manually applying pressure on the recesses whereby an opening is formed in the sheet at the place of the recess. The tablet or capsule can then be removed via said opening. [0278] Another specific embodiment of a kit is a dispenser designed to dispense the daily doses one at a time in the order of their intended use. Preferably, the dispenser is equipped with a memory-aid, so as to further facilitate compliance with the regimen. An example of such a memory-aid is a mechanical counter that indicates the number of daily doses that has been dispensed. Another example of such a memory-aid is a battery- powered micro-chip memory coupled with a liquid crystal readout, or audible reminder signal which, for example, reads out the date that the last daily dose has been taken and/or reminds one when the next dose is to be taken.

General Procedures

[0288] It will be readily recognized that certain compounds for use with the present invention have atoms with linkages to other atoms that confer a particular stereochemistry

to the compound (e.g., chiral centers). It is recognized that synthesis of compounds for use with the present invention may result in the creation of mixtures of different stereoisomers (i.e., enantiomers and diastereomers). Unless a particular stereochemistry is specified, recitation of a compound is intended to encompass all of the different possible stereoisomers.

[0289] Various methods for separating mixtures of different stereoisomers are known in the art. For example, a racemic mixture of a compound may be reacted with an optically active resolving agent to form a pair of diastereoisomeric compounds. The diastereomers may then be separated in order to recover the optically pure enantiomers. Dissociable complexes may also be used to resolve enantiomers (e.g. , crystalline diastereoisomeric salts). Diastereomers typically have sufficiently distinct physical properties (e.g., melting points, boiling points, solubilities, reactivity, etc.) and can be readily separated by taking advantage of these dissimilarities. For example, diastereomers can typically be separated by chromatography or by separation/resolution techniques based upon differences in solubility. A more detailed description of techniques that can be used to resolve stereoisomers of compounds from their racemic mixture can be found in Jean Jacques Andre Collet, Samuel H. Wilen, Enantiomers, Racemates and Resolutions, John Wiley & Sons, Inc. (1981).

[0290] Compounds for use with the present invention can also be prepared as a pharmaceutically acceptable acid addition salt by reacting the free base form of the compound with a pharmaceutically acceptable inorganic or organic acid. Alternatively, a pharmaceutically acceptable base addition salt of a compound can be prepared by reacting the free acid form of the compound with a pharmaceutically acceptable inorganic or organic base. Inorganic and organic acids and bases suitable for the preparation of the pharmaceutically acceptable salts of compounds are set forth in the definitions section of this Application. Alternatively, the salt forms of the compounds can be prepared using salts of the starting materials or intermediates.

[0291] The free acid or free base forms of the compounds can be prepared from the corresponding base addition salt or acid addition salt form. For example, a compound in an acid addition salt form can be converted to the corresponding free base by treating with a suitable base (e.g., ammonium hydroxide solution, sodium hydroxide, and the like). A

compound in a base addition salt form can be converted to the corresponding free acid by treating with a suitable acid (e.g., hydrochloric acid, etc).

[0292] The iV-oxides of compounds for use with the present invention can be prepared by methods known to those of ordinary skill in the art. For example, iV-oxides can be prepared by treating an unoxidized form of the compound with an oxidizing agent (e.g., trifluoroperacetic acid, permaleic acid, perbenzoic acid, peracetic acid, meto-chloroperoxybenzoic acid, or the like) in a suitable inert organic solvent (e.g., a halogenated hydrocarbon such as dichloromethane) at approximately 0 0 C. Alternatively, the iV-oxides of the compounds can be prepared from the iV-oxide of an appropriate starting material.

[0293] Compounds in an unoxidized form can be prepared from JV-oxides of compounds by treating with a reducing agent (e.g., sulfur, sulfur dioxide, triphenyl phosphine, lithium borohydride, sodium borohydride, phosphorus trichloride, tribromide, or the like) in an suitable inert organic solvent (e.g., acetonitrile, ethanol, aqueous dioxane, or the like) at 0 to 80 0 C.

[0294] Prodrug derivatives of the compounds can be prepared by methods known to those of ordinary skill in the art (e.g., for further details see Saulnier et αl. (1994), Bioorgαnic and Medicinal Chemistry Letters, Vol. 4, p. 1985). For example, appropriate prodrugs can be prepared by reacting a non-derivatized compound with a suitable carbamylating agent (e.g., lj-acyloxyalkylcarbonochloridate^αrα-nitrophenyl carbonate, or the like).

[0301] The starting materials and reagents used in preparing these compounds are either available from commercial suppliers such as the Aldrich Chemical Company (Milwaukee, WI), Bachem (Torrance, CA), Sigma (St. Louis, MO), or may be prepared by methods well known to a person of ordinary skill in the art, following procedures described in such standard references as Fieser and Fieser's Reagents for Organic Synthesis, vols. 1-23, John Wiley and Sons, New York, NY, 2006; Rodd's Chemistry of Carbon Compounds, vols. 1-5 and supps., Elsevier Science Publishers, 1998; Organic Reactions, vols. 1-68, John Wiley and Sons, New York, NY, 2007; March J.: Advanced Organic Chemistry, 5th ed., 2001, John Wiley and Sons, New York, NY; and Larock: Comprehensive Organic Transformations, 2nd edition, John Wiley and Sons, New York, 1999. The entire disclosures of all documents cited throughout this application are incorporated herein by reference.

[0302] Various methods for separating mixtures of different stereoisomers are known in the art. For example, a racemic mixture of a compound may be reacted with an optically active resolving agent to form a pair of diastereoisomeric compounds. The diastereomers may then be separated in order to recover the optically pure enantiomers. Dissociable complexes may also be used to resolve enantiomers (e.g., crystalline diastereoisomeric salts). Diastereomers typically have sufficiently distinct physical properties (e.g., melting points, boiling points, solubilities, reactivity, etc.) and can be

readily separated by taking advantage of these dissimilarities. For example, diastereomers can typically be separated by chromatography or by separation/resolution techniques based upon differences in solubility. A more detailed description of techniques that can be used to resolve stereoisomers of compounds from their racemic mixture can be found in Jean Jacques, Andre Collet, and Samuel H. Wilen, Enantiomers, Racemates and Resolutions, John Wiley & Sons, Inc. (1981).

[0303] Diastereomers have distinct physical properties (e.g., melting points, boiling points, solubilities, reactivity, etc.) and can be readily separated by taking advantage of these dissimilarities. The diastereomers can be separated by chromatography or, preferably, by separation/resolution techniques based upon differences in solubility. The optically pure enantiomer is then recovered, along with the resolving agent, by any practical means that would not result in racemization. A more detailed description of the techniques applicable to the resolution of stereoisomers of compounds from their racemic mixture can be found in Jean Jacques, Andre Collet, and Samuel H. Wilen, Enantiomers, Racemates and Resolutions, John Wiley & Sons, Inc. (1981).

[0304] Chiral components can be separated and purified using any of a variety of techniques known to those skilled in the art. For example, chiral components can be purified using supercritical fluid chromatography (SFC). In one particular variation, chiral analytical SFC/MS analyses are conducted using a Berger analytical SFC system (AutoChem, Newark, DE) which consists of a Berger SFC dual pump fluid control module with a Berger FCM 1100/1200 supercritical fluid pump and FCM 1200 modifier fluid pump, a Berger TCM 2000 oven, and an Alcott 718 autosampler. The integrated system can be controlled by BI-SFC Chemstation software version 3.4. Detection can be accomplished with a Waters ZQ 2000 detector operated in positive mode with an ESI interface and a scan range from 200-800 Da with 0.5 second per scan. Chromatographic separations can be performed on a ChiralPak AD-H, ChiralPak AS-H, ChiralCel OD-H, or ChiralCel OJ-H column (5 D4.6 x 250 mm; Chiral Technologies, Inc. West Chester, PA) with 10 to 40% methanol as the modifier and with or without ammonium acetate (10 mM). Any of a variety of flow rates can be utilized including, for example, 1.5 or 3.5 mL/min with an inlet pressure set at 100 bar. Additionally, a variety of sample injection conditions can be used including, for example, sample injections of either 5 or 10 DL in methanol at 0.1 mg/mL in concentration.

[0305] In another variation, preparative chiral separations are performed using a Berger MultiGram II SFC purification system. For example, samples can be loaded onto a ChiralPak AD column (21 x 250 mm, 10D). In particular variations, the flow rate for separation can be 70 mL/min, the injection volume up to 2 mL, and the inlet pressure set at 130 bar. Stacked injections can be applied to increase the efficiency. [0306] Descriptions of the syntheses of particular compounds according to the present invention based on the above reaction schemes and variations thereof are set forth in the Example section.

Biological Testing

[0307] The activity of compounds as renin inhibitors may be assayed in vitro, in vivo or in a cell line. Example D below provides an in vitro enzymatic activity assay for activity against renin.

[0308] Test compounds in varying concentrations may be reacted with recombinant human renin in the presence of substrate, e.g., QXL520-γ-Abu-Ile-His-Pro-Phe-His-Leu-

Val-Ile-His-Thr-Lys (HiLyteFluo488)-Arg-OH (Anaspec, San Jose, CA). The reaction can be followed kinetically using fluorescence (excitation λ=485nm; emission λ=538nm).

Inhibition constants (IC 50 ) may be calculated by non-linear curve fitting of the compound concentrations and fluorescence intensities to the standard IC50 equation.

[0309] Similarly, the protease inhibitory activities of the compounds of the invention can be readily determined by methods known to those of ordinary skill in the art since suitable in vitro assays for measuring protease activity and the inhibition thereof by test compounds are known. Examples of assays that may be used for measuring protease inhibitory activity and selectivity are set forth in Examples E-H.

[0310] IC 50 values for selected compounds of the present invention are given in Table

1.

Example A: Expression of Preprorenin and purification of prorenin

[0433] The sequence of human wild-type renin is known in the art; see, Imai, T. et al., Proc. Natl. Acad. Sci. USA 1983, 80, 7105-7409. It is noted that the fragment of the renin protein useful for the assay comprises amino acid residues 67-406 of human renin (active renin). To prepare active renin, a fragment longer than active renin, a preprorenin (e.g., comprising residues 1-406), may be expressed and from which a prorenin (e.g., comprising residues 23-406) may be recovered. The prorenin may later be cleaved to obtain active renin.

[0434] Expression of human preprorenin (residues 1-406) can be conducted using a FreeStyle 293 Expression System (Invitrogen Corp.), wherein the plasmid DNA for human prorenin expression (pcDNA3.1(+)/hREN) is used to conduct transient expression in FreeStyle 293 -F cells. After trans fection of the plasmid DNA, the cells are subjected to shaking at 37°C, 8% CO2 and 125 rpm for 3 days.

[0435] The prorenin protein is then accumulated and purified by salting out. Powdered ammonium sulfate is added to the culture medium and dissolved to make a 40 % saturation of the salt. The resulting precipitate can be collected by centrifugation and discarded. Ammonium sulfate is added to the remaining solution and dissolved to make an 80 % saturation of salt. The resulting precipitate can be collected by, for example, centrifugation. The prorenin protein is recovered by dissolving the precipitate in buffer. [0436] The concentrated liquid is subjected to gel filtration chromatography using, for example, HiLoad 16/60 Superdex 200 pg (Amersham Biosciences, Inc.) equilibrated with

20 mM Tris-hydrochloric acid (pH 8.0) containing 0.15 M sodium chloride, at a flow rate of 1.4 ml/min, to obtain 3.6 mg of purified prorenin (residues 24 - 406).

Example B: Purification of active renin

[0437] To 3.6 mg of prorenin (residues 24 - 406, as prepared in Example A) dissolved in 5.2 ml of 0.1 M Tris-hydrochloric acid (pH 8.0), is added 12 μg of trypsin (Roche Diagnostics Corp.), and the mixture is allowed to react at 28°C for 55 minutes to carry out activation of renin. After the reaction, 0.4 ml of immobilized trypsin inhibitor (Pierce Biotechnology, Inc.) is added to remove the trypsin used in the activation, by adsorption. The reaction liquid containing the active renin is concentrated using Vivaspin 20 (molecular weight of the fraction 10,000; Vivascience, Inc.), and diluted with 20 mM Tris- hydrochloric acid (pH 8.0). The diluted liquid is fed to a TSKgel DEAE-5 PW column (7.5 mm LD. x 75 mm, Tosoh Corp.) equilibrated with 20 mM Tris-hydrochloric acid (pH 8.0) at a flow rate of 1 ml/min to adsorb the active renin (residues 67 - 406). The column is washed with the buffer solution used for the equilibration, and then elution is carried out by means of a linear concentration gradient of sodium chloride from 0 M to 0.3 M, to obtain 1.5 mg of purified active renin (residues 67 - 406).

Example C: Establishment of renin expressing vector

[0438] A plasmid DNA to express human renin in HEK293 cells can be prepared as follows. PCR is carried out using human renal cDNA (Clontech Laboratories, Inc., Marathon Ready cDNA) as the template and using two synthetic DNAs (5'-AAGCTTATGGATGGATGGAGA-S' (SEQ ID NO: 1) and

5'-GGATCCTCAGCGGGCCAAGGC-S' (SEQ ID NO: 2)), and the obtained fragment is cloned using TOPO TA Cloning Kit (Invitrogen Corp.). The obtained fragment is subcloned into pcDNA3.1(+) that has been cleaved by HindIII and BamHI, to obtain a plasmid DNA for human preprorenin expression (pcDNA3. l(+)/hREN).

[0439] Solutions of test compounds in varying concentrations (≤2 rnM final concentration) are prepared in dimethyl sulfoxide (DMSO) and then diluted into assay buffer comprising 50 rnM Hepes, 1 mM EDTA, 1 mM DTT, 0.1 mg/ml BSA, 0.01% Brij35, pH 7.4. Alternatively, the assay can be performed with a high BSA concentration, wherein the buffer contains an additional 2% BSA.

[0440] Recombinant human renin (3 nM final concentration) is added to the dilutions and pre -incubated with the compounds for 10 minutes at 37 0 C. As described in Examples A-C above, human renin can be obtained by expressing preprorenin (residue 1-406) in mammalian cells, treating the prorenin (residues 24 - 406) contained in the culture supernatant with trypsin, and isolate the active form (residues 67 - 406). After preincubation, the reaction is initiated with 1 μM of substrate QXL520-γ-Abu-Ile-His-Pro- Phe-His-Leu-Val-Ile-His-Thr-Lys (HiLyteFluo488)-Arg-OH (Anaspec, San Jose, CA). The final DMSO in the assay is 5%. The total volume of the reaction mixture is 20 μL, which can be placed on Greiner 384-well small volume plates. [0441] Renin activity may be determined via fluorescence (excitation λ=485 nm; emission λ=538 nm), e.g., on a Molecular Devices SPECTROmax GEMINI XPS. The fluorescence intensity is determined upon the addition of substrate and determined again after incubation at 37 oC for one hour. The fluorescence intensity of a blank (no inhibition) using vehicle alone is also determined. Renin activity is linearly proportional to the change in fluorescence observed (final - initial). [0442] The percent inhibition of renin at a given compound concentration is defined as:

100% x [1 - (Fcompound/Fblank)] where Fcompound is the observed fluorescence at a given concentration of test compound and Fb lank is the observed fluorescence in the presence of vehicle alone. [0443] The pIC50 value (negative log of the molar concentration of the compound that produces 50% inhibition) of a test compound is calculated by non-linear least squares curve fitting of the equation:

Percent Inhibition = 100% / (1 + (10-pIC50 / 101og[I])) to percent inhibition versus compound concentration. The 50% inhibitory concentration (IC 50 ) of a test compound is calculated by raising 10 to the negative pICso (10-pICso).

Example E: Assaying the in vitro enzymatic activity of inhibitors against DPP-IV

[0444] Solutions of test compounds in varying concentrations (≤IO mM final concentration) were prepared in dimethyl sulfoxide (DMSO) and then diluted into assay buffer comprising: 2OmM Tris, pH 7.4; 2OmM KCl; and O.lmg/mL BSA. Human DPP-IV (0.1 nM final concentration) was added to the dilutions and pre -incubated for 10 minutes at ambient temperature before the reaction was initiated with A-P-7-amido-4- trifluoromethylcoumarin (AP-AFC; 10 μM final concentration). The total volume of the reaction mixture was 10-100 μL depending on assay formats used (384 or 96 well plates). The reaction was followed kinetically (excitation λ=400 nm; emission λ=505 nm) for 5-10 minutes or an end-point was measured after 10 minutes. Inhibition constants (IC 50 ) were calculated from the enzyme progress curves using standard mathematical models.

Example F: Assaying the in vitro enzymatic activity of inhibitors against FAPα

[0445] Solutions of test compounds in varying concentrations (≤IO mM final concentration) were prepared in dimethyl sulfoxide (DMSO) and then diluted into assay buffer comprising: 2OmM Tris, pH 7.4; 2OmM KCl; and 0.1mg/mL BSA. Human FAPα (2 nM final concentration) was added to the dilutions and pre-incubated for 10 minutes at ambient temperature before the reaction was initiated with A-P-7-amido-4- trifluoromethylcoumarin (AP-AFC; 40 μM final concentration). The total volume of the reaction mixture was 10-100μL depending on assay formats used (384 or 96 well plates). The reaction was followed kinetically (excitation λ=400 nm; emission λ=505 nm) for 5-10 minutes or an end-point was measured after 10 minutes. Inhibition constants (IC 50 ) were calculated from the enzyme progress curves using standard mathematical models.

Example G: Assaying the in vitro enzymatic activity of inhibitors against PREP

[0446] Solutions of test compounds in varying concentrations (≤lOmM final concentration) were prepared in dimethyl sulfoxide (DMSO) and then diluted into assay buffer comprising: 2OmM Sodium Phosphate, pH 7.4; 0.5mM EDTA; 0.5mM DTT; and 0.1mg/mL BSA. PREP (EC3.4.21.26 from Flavobacterium meningosepticum; 0.2 nM final concentration) was added to the dilutions. The PREP and compound were pre- incubated for 10 minutes at ambient temperature before the reaction was initiated with Z- G-P-AMC (10 μM final concentration). The total volume of the reaction mixture was 10-

100 μL depending on assay formats used (384 or 96 well plates). The reaction was followed kinetically (excitation λ=375 nm; emission λ=460 nm) for 10 minutes or an end- point was measured after 10 minutes. Inhibition constants (IC 50 ) were calculated from the enzyme progress curves using standard mathematical models.

Example H: Assaying the in vitro enzymatic activity of inhibitors against Tryptase

[0447] Solutions of test compounds in varying concentrations (≤lOmM final concentration) were prepared in dimethyl sulfoxide (DMSO) and then diluted into assay buffer comprising: 10OmM Hepes, pH 7.4; 0.01% Brij35; and 10% glycerol. Tryptase (rhLung beta; 0.1 nM final concentration) was added to the dilutions and pre-incubated with compound for 10 minutes at ambient temperature. The enzymatic reaction was initiated with 25 μM Z-lys-SBzl and 400μM DTNB. The total volume of the reaction mixture was lOOμL in Costar A/2 96 well plates. The reaction was followed colorimetrically (λ=405 nm) for 10 minutes. Inhibition constants (IC 50 ) were calculated from the enzyme progress curves using standard mathematical models. [0448] Compounds of the invention were tested according to the above-described assays for protease inhibition and observed to exhibit selective DPP-IV inhibitory activity. For example, compounds of the invention were found to inhibit DPP-IV activity at concentrations that are at least 50 fold less than those concentrations required to produce an equiactive inhibition of protease activity for FAPα. The apparent inhibition constants (K 1 ) for compounds of the invention, against DPP-IV, were in the range from about 10 "9 M to about 10 "5 M.
