ANTICOAGULANTS

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application claims priority benefit of U.S. provisional application Ser. No. 60/780,610, filed March 9, 2006, which is incorporated by reference herein.

FIELD OF THE INVENTION [0002] The present invention provides novel 2-(aryloxy)acetamides, and analogues thereof, which are selective inhibitors of the serine protease coagulation factor Vila. This invention also relates to pharmaceutical compositions comprising these compounds and methods of using the same.

BACKGROUND OF THE INVENTION

[0003] Factor VII is a plasma serine protease involved in the initiation of the coagulation cascade. It is present in human blood at a concentration of approximately 500 ng/mL, with about 1% of the total amount in the proteolytically active form factor Vila (Morrissey, J. H. et al. Blood 1993, 81, 734-744). Factor Vila binds with high affinity to its cofactor, tissue factor, in the presence of calcium ions to form a complex with enhanced proteolytic activity (Carson, S.D. and Brozna, J.P. Blood Coag. Fibrinol. 1993, 4, 281-292). Tissue factor is normally expressed in cells surrounding the vasculature, and is exposed to factor Vila in blood by vessel injury or atherosclerotic plaque rupture. Once formed, the tissue factor/factor Vila complex initiates blood coagulation by proteolytic cleavage of factor X to factor Xa, factor IX to factor IXa and autoactivation of additional factor VII to Vila. Factor Xa, generated either directly by tissue factor/factor Vila or indirectly through action of factor IXa, catalyzes the conversion of prothrombin to thrombin. Thrombin converts fibrinogen to fibrin, which polymerizes to form the structural framework of a blood clot, and activates platelets, which are a key cellular component of coagulation (Hoffman, M. Blood Reviews 2003, 17, S1-S5). In addition, there is evidence that tissue factor is present in blood, likely in an encrypted form that is de-encrypted during clot

formation. (Giesen, P. L. A. et al. Proc. Natl. Acad. ScL 1999, 96, 2311-2315; Himber, J. et al. J. Thromb. Haemost. 2003, 1, 889-895). The tissue factor/factor Vila complex derived from blood borne tissue factor may play an important role in propagation of the coagulation cascade (clot growth) and in thrombus formation in the absence of vessel wall injury (i.e., stasis induced deep vein thrombosis or sepsis). The source of blood borne tissue factor is an area of active research (Morrissey, J. H. J. Thromb. Haemost. 2003, 1, 878-880).

[0004] While blood coagulation is essential to the regulation of an organism's hemostasis, it is also involved in many pathological conditions. In thrombosis, a blood clot, or thrombus, may form and obstruct circulation locally, causing ischemia and organ damage. Alternatively, in a process known as embolism, the clot may dislodge and subsequently become trapped in a distal vessel, where it again causes ischemia and organ damage. Diseases arising from pathological thrombus formation are collectively referred to as thrombotic or thromboembolic disorders and include acute coronary syndrome, unstable angina, myocardial infarction, ischemic stroke, deep vein thrombosis, peripheral occlusive arterial disease, transient ischemic attack, and pulmonary embolism. In addition, thrombosis occurs on artificial surfaces in contact with blood, including catheters and artificial heart valves. Therefore, drugs that inhibit blood coagulation, or anticoagulants, are "pivotal agents for prevention and treatment of thromboembolic disorders" (Hirsh, J. et al. Blood 2005, 105, 453- 463).

[0005] Because of its key role in the coagulation cascade, researchers have postulated that inhibition of factor Vila could be used to treat or prevent thrombotic or thromboembolic disease. (Girard, T. J.; Nicholson, N. S. Curr. Opin. Pharmacol. 2001, 1, 159-163; Lazarus, R. A., et al. Curr. Med. Chem. 2004, 11, 2275-2290; Frederick, R. et al. Curr. Med. Chem. 2005, 12, 397-417.) Several studies have confirmed that various biological and small molecule inhibitors of factor Vila have in vivo antithrombotic efficacy with a low bleeding liability. For instance, it has been demonstrated that a biological factor Vila inhibitor XKl, comprising a hybrid of Factor X light chain and tissue factor pathway inhibitor first kunitz domain, prevents thrombus formation in a rat model of arterial thrombosis, with no change in bleeding time or total blood loss (Szalony, J. A. et al. J. Thrombosis and Thrombolysis 2002,

14, 113-121). In addition, small molecule active site directed factor Vila inhibitors have demonstrated antithrombotic efficacy in animal models of arterial thrombosis (Suleymanov, O., et al. J Pharmacology and Experimental Therapeutics 2003, 306, 1115-1121; Olivero, A. G. et al. J. Biol. Chem. 2005, 280, 9160-9169; Young, W. B., et al. Bioorg. Med. Chem. Lett. 2006, 16, 2037-2041; Zbinden, K. G. et al. Bioorg. Med. Chem. 2006, 14, 5357-5369) and venous thrombosis (Szalony, J. A., et al. Thrombosis Research 2003, 112, 167-174; Arnold, C. S., et al. Thrombosis Research 2006, 117, 343-349), with little impact on bleeding time or blood loss. Moreover, the biological factor Vila inhibitor recombinant nematode anticoagulant protein c2 (rNAPc2) is currently under clinical investigation for treatment of acute coronary syndromes. Results of initial clinical trials demonstrate that rNAPc2 prevents deep vein thrombosis in patients undergoing total knee replacement (Lee, A., et al. Circulation 2001, 104, 74-78), reduces systemic thrombin generation in patients undergoing coronary angioplasty (Moons, A. H. M. J. Am. Coll. Cardiol. 2003, 41, 2147-2153), and reduces magnitude and duration of ischemic events in patients with acute coronary syndromes (Giugliano, R. P. et al. World Congress of Cardiology 2006, Barcelona, Poster #3897).

[0006] Work has accordingly been performed to identify and optimize factor

Vila inhibitors. For example, US 5,866,542 describes recombinant nematode anticoagulant proteins which inhibit factor Vila. US 5,843,442 discloses monoclonal antibodies or antibody fragments possessing factor Vila inhibitory activity, and US 5,023,236 presents tripeptides and tripeptide derivatives that inhibit factor Vila. [0007] While a number of factor Vila inhibitors have been discussed in the art, improved inhibitors, especially non-peptide inhibitors, of serine proteases for the treatment of thromboembolic disorders are always desirable. The present invention discloses 2-(aryloxy)acetamides and analogues thereof as inhibitors of coagulation factor Vila and, as such, their utility in the treatment of thromboembolic disorders. [0008] In addition, it is also desirable to find new compounds with improved pharmacological characteristics compared with known serine protease inhibitors. For example, it is preferred to find new compounds with improved factor Vila inhibitory activity and improved selectivity for factor Vila versus other serine proteases. Also, it is preferred to find new compounds with improved activity in in vitro clotting

assays, such as the prothrombin time (PT) assay, (for a description of the PT assay see, Goodnight, S. H.; Hathaway, W. E. Screening Tests of Hemostasis. Disorders of Thrombosis and Hemostasis: a clinical guide, 2 ^nd edition, McGraw-Hill: New York, 2001 pp. 41-51). It is also desirable and preferable to find compounds with advantageous and improved characteristics in one or more of the following categories, which are given as examples and are not intended to be limiting: (a) pharmacokinetic properties, including oral bioavailability, half life, and clearance; (b) pharmaceutical properties; (c) dosage requirements; (d) factors which decrease blood concentration peak-to-trough characteristics; (e) factors that increase the concentration of active drug at the receptor; (f) factors that decrease the liability for clinical drug-drug interactions; (g) factors that decrease the potential for adverse side-effects, including selectivity versus other biological targets; and (h) factors that improve manufacturing costs or feasibility.

[0056] The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. This invention

encompasses all combinations of preferred aspects of the invention noted herein. It is understood that any and all embodiments of the present invention may be taken in conjunction with any other embodiment or embodiments to describe additional more preferred embodiments. It is also to be understood that each individual element of the preferred embodiments is its own independent preferred embodiment. Furthermore, any element of an embodiment is meant to be combined with any and all other elements from any embodiment to describe an additional embodiment.

DEFINITIONS [0057] The compounds herein described may have asymmetric centers.

Compounds of the present invention containing an asymmetrically substituted atom may be isolated in optically active or racemic forms. It is well known in the art how to prepare optically active forms, such as by resolution of racemic forms or by synthesis using optically active starting materials or optically active catalysts. Geometric isomers of double bonds such as olefins and C=N double bonds can also be present in the compounds described herein, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present invention are described and may be isolated as a mixture of isomers or as separated isomeric forms. All chiral, diastereomeric, racemic forms and all geometric isomeric forms of a structure are intended, unless the specific stereochemistry or isomeric form is specifically indicated. When no specific mention is made of the configuration (cis, trans or R or S) of a compound (or of an asymmetric carbon), then any one of the isomers or a mixture of more than one isomer is intended. The processes for preparation can use racemates, enantiomers, or diastereomers as starting materials. All processes used to prepare compounds of the present invention and intermediates made therein are considered to be part of the present invention. When enantiomeric or diastereomeric products are prepared, they can be separated by conventional methods, for example, by chromatography or fractional crystallization. Compounds of the present invention, and salts thereof, may exist in multiple tautomeric forms, in which hydrogen atoms are transposed to other parts of the molecules and the chemical bonds between the atoms of the molecules are consequently rearranged. It should be understood that all tautomeric forms, insofar as

they may exist, are included within the invention. The inventive compounds may be in the free or hydrate form.

[0058] Preferably, the molecular weight of compounds of the present invention is less than about 500, 550, 600, 650, 700, 750, or 800 grams per mole. Preferably, the molecular weight is less than about 800 grams per mole. More preferably, the molecular weight is less than about 700 grams per mole. Even more preferably, the molecular weight is less than about 600 grams per mole. [0059] The term "substituted," as used herein, means that any one or more hydrogens on the designated atom is replaced with a selection from the indicated group, provided that the designated atom's normal valency is not exceeded, and that the substitution results in a stable compound. When a substituent is keto (i.e., =0), then 2 hydrogens on the atom are replaced. When a ring system (e.g., carbocyclic or heterocyclic) is said to be substituted with a carbonyl group or a double bond, it is intended that the carbon atom of the carbonyl group or one carbon atom of the double bond be part of (i.e., within) the ring. Ring double bonds, as used herein, are double bonds that are formed between two adjacent ring atoms (e.g., C=C, C=N, or N=N). [0060] In cases wherein there are nitrogen atoms (e.g., amines) on compounds of the present invention, these may be converted to N-oxides by treatment with an oxidizing agent (e.g., mCPBA and/or hydrogen peroxides) to afford other compounds of this invention. Thus, shown and claimed nitrogen atoms are considered to cover both the shown nitrogen and its N-oxide (N- >O) derivative. In cases wherein there are quarternary carbon atoms on compounds of the present invention, these may be replaced by silicon atoms, provided they do not form Si-N or Si-O bond. [0061] When any variable occurs more than one time in any constituent or formula for a compound, its definition at each is independent of its definition at every other . Thus, for example, if a group is shown to be substituted with 0-3 R ^f , then said group may optionally be substituted with up to three R ^f groups and R ^f at each is selected independently from the definition of R ^f . [0062] When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded

via any atom in such substituent. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

Heteroaryl groups include, without limitation, pyridyl, pyrimidinyl, pyrazinyl, pyridazinyl, triazinyl, furyl, quinolyl, isoquinolyl, thienyl, imidazolyl, thiazolyl, indolyl, pyrryl, oxazolyl, oxadiazolyl, benzofuryl, benzothienyl, benzthiazolyl, isoxazolyl, pyrazolyl, triazolyl, tetrazolyl indazolyl, 1,2,4-thiadiazolyl, isothiazolyl, benzothienyl, purinyl, carbazolyl, benzimidazolyl, 2,3-dihydrobenzofuranyl, 2,3-dihydrobenzothienyl, 2,3-dihydrobenzothienyl-S-oxide, 2,3-dihydrobenzothienyl-S-dioxide, benzoxazolin-2-on-yl, indolinyl, benzodioxolanyl, benzodioxane, and the like. Heteroaryl groups can be substituted or unsubstituted. [0082] Also included are fused ring and spiro compounds containing, for example, the above carbocycles or heterocycles.

[0083] Bridged rings are also included in the definition of carbocycle or heterocycle. A bridged ring occurs when one or more atoms (i.e., C, O, N, or S) link two non-adjacent carbon or nitrogen atoms. Preferred bridges include, but are not limited to, one carbon atom, two carbon atoms, one nitrogen atom, two nitrogen atoms, and a carbon-nitrogen group. It is noted that a bridge always converts a monocyclic ring into a tricyclic ring. When a ring is bridged, the substituents recited for the ring may also be present on the bridge.

[0084] When a dotted ring is used within a ring structure, this indicates that the ring structure may be saturated, partially saturated or unsaturated. [0085] The term "counterion" is used to represent a small, negatively charged species such as chloride, bromide, hydroxide, acetate, and sulfate. [0086] The phrase "pharmaceutically acceptable" is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio. [0087] As used herein, "pharmaceutically acceptable salts" refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic groups such as amines; and alkali or organic salts of acidic groups such as carboxylic acids. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, and nitric; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2- acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, and isethionic, and the like. [0088] The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found in Remington's

Pharmaceutical Sciences , 18th ed., Mack Publishing Company, Easton, PA, 1990, the disclosure of which is hereby incorporated by reference.

[0089] Isotopically labeled compounds of the present invention, i.e., wherein one or more of the atoms described are replaced by an isotope of that atom (e.g., C replaced by ¹³ C or by ¹⁴ C; and isotopes of hydrogen include tritium and deuterium), are also provided herein. Such compounds have a variety of potential uses, e.g., as standards and reagents in determining the ability of a potential pharmaceutical to bind to target proteins or receptors, or for imaging compounds of this invention bound to biological receptors in vivo or in vitro.

[0090] Compounds of the present invention are, subsequent to their preparation, preferably isolated and purified to obtain a composition containing an amount by weight equal to or greater than 98%, preferably 99%, compound of the present invention ("substantially pure"), which is then used or formulated as described herein. Such "substantially pure" compounds are also contemplated herein as part of the present invention.

[0091] "Stable compound" and "stable structure" are meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent. It is preferred that compounds of the present invention do not contain a N-halo, S(O^H, or S(O)H group.

[0092] In addition, compounds of formula I may have prodrug forms. Any compound that will be converted in vivo to provide the bioactive agent (i.e., a compound of formula I) is a prodrug within the scope and spirit of the invention. Various forms of prodrugs are well known in the art. For examples of such prodrug derivatives, see: a) Design of Prodrugs, edited by H. Bundgaard, (Elsevier, 1985), and Methods in Enzymology, Vol. 42, at pp. 309-396, edited by K. Widder, et. al. (Academic Press, 1985); b) A Textbook of Drug Design and Development, edited by Krosgaard-Larsen and H. Bundgaard, Chapter 5, "Design and Application of Prodrugs," by H. Bundgaard, at pp. 113-191 (1991); c) H. Bundgaard, Advanced Drug Delivery Reviews, Vol. 8, p. 1-38 (1992); d) H. Bundgaard, et al, Journal of Pharmaceutical Sciences, Vol. 77, p. 285 (1988); and

e) N. Kakeya, et. al, Chem Phar Bull, Vol. 32, p. 692 (1984). [0093] Preparation of prodrugs is well known in the art and described in, for example, Medicinal Chemistry: Principles and Practice, ed. F. D. King, The Royal Society of Chemistry, Cambridge, UK, 1994, which is incorporated herein by reference in its entirety.

[0094] Compounds containing a carboxy group can form physiologically hydrolyzable esters which serve as prodrugs by being hydrolyzed in the body to yield formula I compounds per se. Such prodrugs are preferably administered orally since hydrolysis in many instances occurs principally under the influence of the digestive enzymes. Parenteral administration may be used where the ester per se is active, or in those instances where hydrolysis occurs in the blood. Examples of physiologically hydrolyzable esters of compounds of formula I include Cγ ^alkylbenzyl, 4- methoxybenzyl, indanyl, phthalyl, methoxymethyl, Ci_6 alkanoyloxy-C^alkyl, e.g. acetoxymethyl, pivaloyloxymethyl or propionyloxymethyl, C^alkoxycarbonyloxy- C^alkyl, e.g. methoxycarbonyl-oxymethyl or ethoxycarbonyloxymethyl, glycyloxymethyl, phenylglycyloxymethyl, (5-methyl-2-oxo- 1 ,3 -dioxolen-4-yl)- methyl and other well known physiologically hydrolyzable esters used, for example, in the penicillin and cephalosporin arts. Such esters may be prepared by conventional techniques known in the art.

[0095] The term "solvate" means a physical association of a compound of this invention with one or more solvent molecules, whether organic or inorganic. This physical association includes hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in the crystal lattice of the crystalline solid. "Solvate" encompasses both solution-phase and isolable solvates. Exemplary solvates include hydrates, ethanolates, methanolates, isopropanolates and the like. Methods of solvation are generally known in the art. [0096] As used herein, the term "patient" or "host" encompasses all mammalian species.

[0097] As used herein, "treating" or "treatment" cover the treatment of a disease-state in a mammal, particularly in a human, and include: (a) preventing the disease-state from occurring in a mammal, in particular, when such mammal is

predisposed to the disease-state but has not yet been diagnosed as having it; (b) inhibiting the disease-state, i.e., arresting it development; and/or (c) relieving the disease-state, i.e., causing regression of the disease state.

[0098] "Therapeutically effective amount" is intended to include an amount of a compound of the present invention that is effective when administered alone or in combination with other active ingredients to inhibit factor Vila or to treat the disorders listed herein. When applied to a combination, the term refers to combined amounts of the active ingredients that result in the therapeutic effect, whether administered in combination, serially or simultaneously. The combination of compounds is preferably a synergistic combination. Synergy, as described, for example, by Chou and Talalay, Adv. Enzyme Regul. 1984, 22:27-55, occurs when the effect (in this case, anticoagulant effect) of the compounds when administered in combination is greater than the additive effect of the compounds when administered alone as a single agent. In general, a synergistic effect is most clearly demonstrated at sub-optimal concentrations of the compounds. Synergy can be in terms of lower cytotoxicity, increased antithrombotic effect, or some other beneficial effect of the combination compared with the individual components. [0099] The term "pharmaceutical composition" means a composition comprising a compound of the invention in combination with at least one additional pharmaceutical carrier. A "pharmaceutically acceptable carrier" refers to media generally accepted in the art for the delivery of biologically active agents to animals, in particular, mammals, including, i.e., adjuvant, excipient or vehicle, such as diluents, preserving agents, fillers, flow regulating agents, disintegrating agents, wetting agents, emulsifying agents, suspending agents, sweetening agents, flavoring agents, perfuming agents, antibacterial agents, antifungal agents, lubricating agents and dispensing agents, depending on the nature of the mode of administration and dosage forms. Pharmaceutically acceptable carriers are formulated according to a number of factors well within the purview of those of ordinary skill in the art. These include, without limitation: the type and nature of the active agent being formulated; the subject to which the agent-containing composition is to be administered; the intended route of administration of the composition; and, the therapeutic indication being targeted. Pharmaceutically acceptable carriers include both aqueous and non-

aqueous liquid media, as well as a variety of solid and semi-solid dosage forms. Such carriers can include a number of different ingredients and additives in addition to the active agent, such additional ingredients being included in the formulation for a variety of reasons, e.g., stabilization of the active agent, binders, etc., well known to those of ordinary skill in the art. Descriptions of suitable pharmaceutically acceptable carriers, and factors involved in their selection, are found in a variety of readily available sources such as, for example, Remington 's Pharmaceutical Sciences, 18th ed., 1990, which is incorporated herein by reference in its entirety.

SYNTHESIS [00102] The compounds of the present invention can be prepared in a number of ways known to one skilled in the art of organic synthesis. The compounds of the present invention can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or by variations thereon as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. The reactions are performed in a solvent appropriate to the reagents and materials employed and suitable for the transformations being effected. It will be understood by those skilled in the art of organic synthesis that the functionality present on the molecule should be consistent with the transformations proposed. This will sometimes require a judgment to modify the order of the synthetic steps or to select one particular process scheme over another in order to obtain a desired compound of the invention.

[00103] A particularly useful compendium of synthetic methods which may be applicable to the preparation of compounds of the present invention may be found in Larock, R. C. Comprehensive Organic Transformations, VCH: New York, 1989. Preferred methods include, but are not limited to, those described below. All references cited herein are hereby incorporated in their entirety herein by reference.

[00104] It will also be recognized that another major consideration in the planning of any synthetic route in this field is the judicious choice of the protecting group used for protection of the reactive functional groups present in the compounds described in this invention. An authoritative account describing the many alternatives to the trained practitioner is Greene and Wuts (Protective Groups In Organic

Synthesis, Wiley-Interscience, 3nd Edition, 1999). All references cited herein are hereby incorporated in their entirety herein by reference. [00105] Compounds having the general Formula (I):

wherein R ⁷ , R ⁸ , R^, W, Y and Z are each as defined above, can be prepared by coupling an acid of Formula (Ia):

(Ia) with an amine of Formula (Ib):

(Ib) under conditions suitable for forming an amide bond between the acid and the amine. Coupling conditions can be found in Bodanszky, "Principles of Peptide Synthesis, Second Edition" Springer Verlag Ed, Berlin (1993). Coupling reagents include CDI, DIC, and EDCI. Optionally, an intermediate activated ester can be prepared by adding one equivalent of 1-hydroxybenzotriazole or l-hydroxy-7-azabenzotriazole. Other coupling reagents include HATU, HBTU, and Py-Brop which are usually reacted in the presence of one equivalent of a tertiary base such as DIEA or TEA. Protection and deprotection of functional groups may be required before or after the amide formation step to afford a compound of Formula (I).

[00106] The intermediate acid of Formula (Ia) can be prepared according to the steps described in Scheme 1. Thus, when X is a leaving group such as Cl, Br or OSC^Me, alcohols 1 (prepared following the methods shown in later Schemes and in the Examples) react with acetate derivatives 2 under basic conditions to give 3. When X = OH, alcohols 1 react with acetate derivatives 2 under Mitsonobu conditions (Bull. Chem. Soc. Jpn. 1967, 40, 2380), for example, in the presence of triphenylphosphine and DEAD. PG is a protecting group such as methyl or benzyl. Deprotection of PG in 3 by hydrolysis or hydrogenation gives acid intermediates Ia.

[00107] For W-OH = l-aminoisoquinolin-6-ol and its derivatives, these alcohols can be prepared following the reactions shown in Scheme 2. Acids 5 can be accessed from bromides 4 via lithium halogen exchange using, for example, M-BuLi, followed by treatment with carbon dioxide. Acids 5 can then be advanced to benzamides 6 via formation of the primary amide using, for example, oxalyl chloride and DMF then ammonium hydroxide, followed by treatment with N, N- dimethylformamide in a solvent such as N,N-dimethylacetamide. Heating benzamides 6 in the presence of a base such as potassium tert-butoxide provides cyclized products 7. These can then be advanced by methods known to those skilled in the art (an example is shown in Scheme 2 and is exemplified later in the Examples) to l-aminoisoquinolin-6-ol and its derivatives (9).

Scheme 2

[00108] Amines of Formula (Ib) are either commercially available or prepared according to the procedures given in the Schemes below and Examples. In general, functionalized benzylamines 11 can be prepared as exemplified in Scheme 3 via reduction of commercially available or prepared benzonitriles 10 (as shown in the Schemes and Examples that follow) via, for example, hydrogenation in the presence of a catalyst such as Pd/C or Raney Nickel, or using a hydride source, such as BH ₃ or

LAH in THF. Alternatively, as shown in Scheme 4, benzylamines 11 can be prepared from esters 12 or aldehydes 13 via reduction to benzyl alcohols 14 using, for example, LAH, followed by conversion to azides 15 with an appropriate reagent such as diphenylphosphoryl azide in a solvent such as THF or toluene. Reduction of azides 15 with, for example, LAH or triphenylphosphine, provides benzylamines 11. Finally, as shown in Scheme 5, benzylamines 11 can also be prepared from esters 12 via hydrolysis, then formation of the primary amide via, for example, treatment with ammonium hydroxide in the presence of appropriate coupling reagents, such as EDC and HOBT or HOAT, followed by reduction of the derived primary amide with a hydride source, such as BH ₃ .

[00109] Amines of Formula (Ib), in which R ⁷ = alkyl can be prepared in several ways. For example, they can be prepared from benzylamines 11 as exemplified in Scheme 6 via protection with, for example, trifluoroacetic anhydride to give 16, followed by alkylation with an alkyl halide, for example, methyl iodide to provide trifluoroacetates 17. Deprotection with a base such as potassium carbonate yields the desired N-methyl benzylamines 18. Amines of Formula (Ib), in which R ⁷ = alkyl can also be prepared from benzamides 20 (see Scheme 7) which can be accessed

from acids 19 via, for example, acid chloride formation and reaction with amine NH ₂ R ⁷ or via coupling with amine NH ₂ R ⁷ in the presence of coupling agents, for example, EDC and HOAT and a base such as DIPEA. Reduction of benzamides 20 via methods known to those skilled in the art provides benzylamines 18. Finally, amines of Formula (Ib), in which R ⁷ = alkyl can also be prepared from aldehydes 13 via reductive amination (Scheme 8) under conditions known to those skilled in the art.

[00110] Benzylamines 23 containing an ortho-sulfone substituent can be prepared, as shown in Scheme 9, from sulfides 21, via oxidation to benzonitrile sulfones 22 with an appropriate oxidizing agent, such as MCPBA. Benzonitriles 22 can then be converted to the corresponding benzylamines 23 as was previously shown in Scheme 3.

Scheme 9

[00111] Sulfides 21 can be prepared in several different ways. As shown in

Scheme 10, one method involves advancing commercially available o- bromobenzonitriles 24 via lithium-halogen exchange using, for example w-butyl lithium at cold temperatures in a solvent such as THF followed by reaction with disulfides R ¹ SSR ¹ . Sulfides 21 can then be converted to the corresponding benzylamines 23 by oxidation to the sulfones then reduction to the benzylamines as was previously shown in Schemes 3 and 9.

Scheme 10

[00112] In addition, as shown in Scheme 11, sulfides 21 can also be prepared from o-cyanophenyldisulfides 25 by reaction with organometallic nucleophiles R ¹ M, for example, Grignard reagents. Sulfides 21 can then be converted to the corresponding benzylamines 23 by oxidation to the sulfones then reduction to the benzylamines as was previously shown in Schemes 3 and 9.

Scheme 11

[00113] As shown in Scheme 12, sulfides 21 can also be prepared from o- fluorobenzonitriles 26 via reaction with R ¹ SH in a solvent such as DMF in the presence of a base such as sodium carbonate. Sulfides 21 can then be converted to the corresponding benzylamines 23 by oxidation to the sulfones then reduction to the benzylamines as was previously shown in Schemes 3 and 9. Also, sulfides 21 can be converted to benzylamines 27 by treatment with a reducing agent, such as BH ₃ .

[00114] Finally, as shown in Scheme 13, sulfides 29 can be prepared from thiosalicylates 28 via alkylation with alkyl halides R ¹ X, followed by oxidation to the sulfones 30 as was previously shown in Scheme 9. The esters 30 can be converted to benzylamines 23 as was previously shown in Scheme 4 or Scheme 5.

Scheme 13

[00115] Benzylamines 33 containing a heterocyclic substituent can be prepared as shown in Scheme 14. Fluorobenzonitriles 26 are treated with amines 31 in a solvent such as acetonitrile. The resulting benzonitriles 32 are then converted to the benzylamines 33 as was previously shown in Scheme 3.

Scheme 14

[00116] As shown in Scheme 15, benzylamines 37 containing an ortho- sulfonamide substituent can be prepared from o-cyano sulfonyl chlorides 34 via reaction with amines 35 (or amine hydrochloride salts) in the presence of a base, for example, TEA, in a solvent such as THF or water. Benzonitriles 36 can then be converted to the corresponding benzylamines 37 as was previously shown in Scheme 3.

Scheme 15

[00117] Benzylamines 40 containing an amide substituent can be derived from cyanobenzoic acids 38 as shown in Scheme 16, by treatment of acids 38 with amines 35 (or amine hydrochloride salts) in the presence of appropriate coupling reagents such as EDC, HOAT and a base such as DIEA. The derived benzonitriles 39 can then be converted to the benzylamines 40 as was previously shown in Scheme 3. Alternatively, amides 40 can be prepared as shown in Scheme 17 from isobenzofuran- l(3H)-ones 41 by treatment with amines 35 in the presence of trimethylaluminum. The derived benzyl alcohols 42 can then be converted to the corresponding benzylamines as was previously shown in Scheme 4.

Scheme 17

[00118] Benzylamines 44 containing an ortho-ether substituent can be prepared, as shown in Scheme 18, from phenols 41, via alkylation with alkyl halides 42. The derived benzonitriles 43 can then be converted to the corresponding benzylamines 44 as was previously shown in Scheme 3.

Scheme 18

[00119] As exemplified in Scheme 19, functionalized benzylamines 48, 51 and

54 containing acetamide, urea or carbamate substituents can be prepared from nitro compounds 45 via reduction to the anilines 46 with, for example, iron in acetic acid. As exemplified in Scheme 20, anilines 46 can be treated with phosgene followed by amine 35 to provide ureas 47, or with anhydrides 49 to provide acetamides 50, or with alkyl chloroformates 52 to give carbamates 53. The benzonitrile products 47, 50 and 53 can then be converted to the desired benzylamines 48, 51 and 54 using methods previously shown in Scheme 3.

[00120] The compound of the instant invention herein described may have asymmetric centers. For example, the chiral carbon atom in Formula (I) as indicated below, exist in either as S or R configuration.

[00121] Thus, the stereoisomeric configurations of each compound of Formula

They are collectively, as well as individually, considered part of the invention. In a preferred stereoisomeric embodiment the present invention provides for a stereoisomeric configuration of isomer- 1 for all embodiments of Formula (I), (II) or (III), or tautomer, pharmaceutically acceptable salt, solvate, or prodrug form thereof.

[00124] To 2,2'-dithio-bis(benzonitrile) (obtained from Sumitomo Seika) (2.00 g, 7.46 mmol) in THF (37 mL) at -78 ⁰ C, a 0.5 M THF solution of cyclopropyl magnesium bromide (149 mL, 74.6 mmol) was added via addition funnel. After 10 min, the reaction was quenched with saturated aqueous ammonium chloride (200 mL). After warming to rt, the reaction product was diluted with water and ethyl

acetate and the layers were separated. The organic layer was washed with water and brine, dried (MgSO ₄ ), filtered and concentrated. The resulting residue was purified via silica gel chromatography eluting with 15% ethyl acetate/hexane to provide 2- (cyclopropylthio)benzonitrile as a yellow oil (1.36 g). The oil was dissolved in CH ₂ Cl ₂ , -75% MCPBA (6.0Og, 26.1 mmol) was added and the reaction was stirred at rt for 2h. IN NaOH was added and the layers were separated.

IF: 4-Methoxy-2-methylbenzoic acid

[00129] A flask equipped with a mechanical stirrer, reflux condenser and addition funnel was charged with magnesium (61.4 g) and THF (1 L) and put under a nitrogen atmosphere. The magnesium was treated with 4-bromo-3-methylanisole (500 g) and the reaction flask was warmed to 40 ⁰ C until reaction was well initiated. The remaining 4-bromo-3-methylanisole (9.5 kg) was added continuously over the next 1.5 h. The reaction temperature was maintained between 50-60 ⁰ C with an ice/ water bath. The ice bath was removed during the last 10% of the addition. Once the last of the bromide was added, the reaction was allowed to stir for 1.5 h, during which time the temperature droped to 35 ⁰ C. At this point, there was very little unconsumed magnesuim remaining, however the reaction solution was heated to 60 ⁰ C for 30 min to ensure completion. The reaction was cooled to -10 ⁰ C and excess carbon dioxide was added into the reaction mixture through the condenser. The reaction became quite thick, and the temperature rose to ~30 ⁰ C. At this point an additional 1 L of THF was added. The carbon dioxide was added until the reaction was complete and the temperature began to drop. A total of 350 mL THF was removed under reduced pressure. The resulting thick slurry was quenched with a mixture of 4.4 L ice cold water and 320 mL concentrated HCl. To the resulting thick white slurry an additional 4 L water was added. The resulting precipitate was filtered and washed with 1.5 L water, dried on the funnel overnight, and dried at 60 ⁰ C under high vacuum to provide 386.05 g of IF as a white powder.

The slurry slowly dissolved during the addition to provide a red solution of acid chloride. CH2CI2 (1.3 L) was removed at 30 ⁰ C with slight vacuum, and the resulting concentrated solution of acid chloride was polish filtered through a course sintered glass funnel to remove some insoluble matter. This filtered solution was concentrated to a crystalline residue and pumped down under high vacuum for 30 min to remove any excess oxalyl chloride. The crystalline residue was dissolved in THF (550 mL) and titrated into a large flask containing ice cold concentrated ammonium hydroxide (1 L) over -15 min. The temperature quickly rose to -30 ⁰ C with the formation of a thick slurry of product. To this oily slurry of product, water (3 L) was added over -15 min to provide a thick white slurry of product. This product was filtered over course sintered glass and washed with water (1.5 L) and dried under nitrogen/vacuum for 36 h. 367.8g of IG was isolated as an off-white solid.

The reaction was maintained at reflux for 1.5 h, and checked by HPLC and TLC (10: 1 CH2CI2 / MeOH). At atmospheric pressure, 1150 mL THF was distilled out and replaced with 1500 mL heptane (Note that if the solution is not quite saturated, remaining THF should be removed by distillation). The remaining solution was cooled slowly to rt overnight with stirring, seeded at 68 ⁰ C. Rapid crystallization was observed. The resulting slurry was cooled to 0 ⁰ C, filtered and washed with heptanes (500 mL) and dried under vacuum at rt for 48 h. 384.6 g (97.4%) of IH was isolated

The resulting thick paste was heated on the rotovap to 90 ⁰ C for -30 min. The reaction thinned to a thick black solution with gas evolution then became pasty again, and was heated continuously at 90 ⁰ C for an additional 30 min and checked by TLC. An additional quantity of phosphorous oxychloride (100 mL, 1.07 mol) was added and the reaction was heated continuously for another 2 h. The reaction was complete (checked by

TLC; complete consumption of starting material with some production of a polar impurity) so the excess POCI3 was removed under high vacuum to leave a solid mass of crude product. This solid mass was triturated with ethyl acetate (500 mL) at 0 ⁰ C for 3.5 h. The solid product was filtered and washed with cold ethyl acetate (250 mL).

The ethyl acetate was removed under reduced pressure to yield 110.8 g crude residue. In order to remove the polar impurity, this residue was dissolved in a mixture of ethyl acetate 200 mL and heptanes 100 mL and passed through a silica gel plug (500 g) and eluted with a mixture of ethyl acetate/heptanes 1 : 1. The product containing fractions was concentrated to a residue to provide pinkish -yellow solids. These solids were recrystallized from hot (~75°C) heptanes (1000 mL) and cooled to rt then to 0 ⁰ C.

UTILITY

[00199] The compounds of the present invention are inhibitors of factor Vila and are useful as anticoagulants for the prevention or treatment of thromboembolic disorders in mammals. In general, a thromboembolic disorder is a circulatory disease

caused by blood clots (i.e., diseases involving fibrin formation, platelet activation, and/or platelet aggregation). The term "thromboembolic disorders (or conditions)" as used herein includes arterial or venous cardiovascular or cerebovascular thromboembolic disorders, and thromboembolic disorders in the chambers of the heart. The term "thromboembolic disorders" as used herein also includes specific disorders selected from, but not limited to, unstable angina or other acute coronary syndromes, atrial fibrillation, first or recurrent myocardial infarction, ischemic sudden death, transient ischemic attack, stroke, atherosclerosis, peripheral occlusive arterial disease, venous thrombosis, deep vein thrombosis, thrombophlebitis, arterial embolism, coronary and cerebral arterial thrombosis, cerebral embolism, kidney embolisms, pulmonary embolisms, and thrombosis resulting from medical implants, devices, or procedures in which blood is exposed to an artificial surface that promotes thrombosis. The medical implants or devices include, but are not limited to: prosthetic valves, artificial valves, indwelling catheters, stents, blood oxygenators, shunts, vascular access ports, and vessel grafts. The procedures include, but not limited to: cardiopulmonary bypass, percutaneous coronary intervention, and hemodialysis.

[00200] It is noted that thrombosis includes vessel occlusion (e.g. after a bypass) and reocclusion (e.g., during or after percutaneous transluminal coronary angioplasty). The thromboembolic disorders may result from conditions including but not limited to atherosclerosis, surgery or surgical complications, prolonged immobilization, arterial fibrillation, congenital thrombophilia, cancer, diabetes, effects of medications or hormones, and complications of pregnancy. The anticoagulant or antithrombotic effect of compounds of the present invention is believed to be due to inhibition of serine proteases involved in the coagulation cascade, more specifically, inhibition of the coagulation factor Vila.

[00201] The term "thrombosis", as used herein, refers to formation or presence of a thrombus (pi. thrombi); clotting within a blood vessel which may cause ischemia or infarction of tissues supplied by the vessel. The term "embolism", as used herein, refers to sudden blocking of an artery by a clot or foreign material which has been brought to its site of lodgment by the blood current. The term "thromboembolism", as used herein, refers to obstruction of a blood vessel with thrombotic material carried by

the blood stream from the site of origin to plug another vessel. The term "stroke", as used herein, refers to embolic stroke or atherothrombotic stroke arising from occlusive thrombosis in the carotid communis, carotid interna, or intracerebral arteries. [00202] The effectiveness of compounds of the present invention as inhibitors of the coagulation factors Vila, IXa, Xa, XIa, plasma kallikrein or thrombin, can be determined using a relevant purified serine protease, respectively, and an appropriate synthetic substrate. The rate of hydrolysis of the chromogenic substrate by the relevant serine protease was measured both in the absence and presence of compounds of the present invention. Hydrolysis of the substrate resulted in the release ofpαrα-nitroaniline (pNA), which was monitored spectrophotometrically by measuring the increase in absorbance at 405 nM, or the release of aminomethylcoumarin (AMC), which was monitored spectrofluorometrically by measuring the increase in emission at 460 nM with excitation at 380 nM. A decrease in the rate of absorbance change at 405 nM in the presence of inhibitor is indicative of enzyme inhibition. Such methods are known to one skilled in the art. The results of this assay are expressed as inhibitory constant, Kj.

[00203] Factor Vila determinations were made in 0.005 M calcium chloride,

0.15 M sodium chloride, 0.05 M HEPES buffer containing 0.5% PEG 8000 at a pH of 7.4. Determinations were made using purified human Factor Vila (Haematologic Technologies) or recombinant human Factor Vila (Novo Nordisk) at a final assay concentration of 2-5 nM, recombinant soluble tissue factor at a concentration of 18-35 nM and the synthetic substrate H-D-Ile-Pro-Arg-pNA (S-2288; Chromogenix or BMPM-2; AnaSpec) at a concentration of 0.001 M. In general, preferred compounds of the present invention, such as the particular compounds disclosed in the above examples, have been identified to be active and exhibit Kj's of equal to or less than 15 μM in the Factor Vila assay, thereby demonstrating the utility of the compounds of the present invention as especially effective inhibitors of coagulation Factor Vila, and thus, as inhibitors of the coagulation cascade and as anticoagulants for the prevention or treatment of thromboembolic disorders in mammals. More preferred compounds have Kj's of equal to or less than 5 μM, preferably equal to or less than 1 μM, more

preferably equal to or less than 0.5 μM, even more preferably equal to or less than 0.1 μM.

[00204] Factor IXa determinations were made in 0.005 M calcium chloride, 0.1

M sodium chloride, 0.05 M TRIS base and 0.5% PEG 8000 at a pH of 7.4. Determinations were made using purified human Factor IXa (Haematologic

Technologies) at a final assay concentration of 20-100 nM and the synthetic substrate PCIXA2100-B (CenterChem) or Pefafluor IXa 3688 (H-D-Leu-Phe-Gly-Arg-AMC; CenterChem) at a concentration of 0.0004-0.0005 M. In general, compounds tested in the Factor IXa assay are considered to be active if they exhibit a K ₁ of equal to or less than 15 μM.

[00205] Factor Xa determinations were made in 0.1 M sodium phosphate buffer at a pH of 7.4 containing 0.2 M sodium chloride and 0.5% PEG 8000. Determinations were made using purified human Factor Xa (Haematologic Technologies) at a final assay concentration of 150-1000 pM and the synthetic substrate S-2222 (Bz-Ile-Glu(gamma-OMe, 50%)-Gly-Arg-pNA; Chromogenix) at a concentration of 0.0002-0.0003 M. In general, compounds tested in the Factor Xa assay are considered to be active if they exhibit a K ₁ of equal to or less than 15 μM. [00206] Factor XIa determinations were made in 50 mM HEPES buffer at pH

7.4 containing 145 mM NaCl, 5 mM KCl, and 0.1% PEG 8000 (polyethylene glycol; JT Baker or Fisher Scientific). Determinations were made using purified human

Factor XIa at a final concentration of 75-200 pM (Haematologic Technologies) and the synthetic substrate S-2366 (pyroGlu-Pro-Arg-pNA; Chromogenix) at a concentration of 0.0002-0.00025 M. In general, compounds tested in the Factor XIa assay are considered to be active if they exhibit a K ₁ of equal to or less than 15 μM. [00207] Plasma kallikrein determinations were made in 0.1 M sodium phosphate buffer at a pH of 7.4 containing 0.2 M sodium chloride and 0.5% PEG 8000. Determinations were made using purified human kallikrein (Enzyme Research Laboratories) at a final assay concentration of 200 pM and the synthetic substrate S- 2302 (H-(D)-Pro-Phe-Arg-pNA; Chromogenix) at a concentration of 0.00008-0.0004 M. The Km value used for calculation of Ki was 0.00005 to 0.00007 M. In general, compounds tested in the plasma kallikrein assay are considered to be active if they exhibit a Kj of equal to or less than 15 μM.

[00208] Thrombin determinations were made in 0.1 M sodium phosphate buffer at a pH of 7.4 containing 0.2 M sodium chloride and 0.5% PEG 8000. Determinations were made using purified human alpha thrombin (Haematologic Technologies or Enzyme Research Laboratories) at a final assay concentration of 200- 250 pM and the synthetic substrate S-2366 (pyroGlu-Pro-Arg-pNA; Chromogenix) at a concentration of 0.0002 M. In general, compounds tested in the thrombin assay are considered to be active if they exhibit a K ₁ of equal to or less than 15 μM. [00209] The selectivity of a compound may be evaluated by taking the ratio of the K ₁ value for a given protease with the K ₁ value for the protease of interest (i.e., selectivity for FVIIa versus protease P = K ₁ for protease P/ K ₁ for FVIIa).

Compounds with selectivity ratios >20 are considered selective. Compounds with selectivity ratios >100 are preferred, and compounds with selectivity ratios > 500 are more preferred. [00210] The Michaelis constant, K _m , for substrate hydrolysis by each protease was determined at 25 ⁰ C using the method of Lineweaver and Burk. Values of Kj were determined by allowing the protease to react with the substrate in the presence of the inhibitor. Reactions were allowed to go for periods of 20-180 minutes (depending on the protease) and the velocities (rate of absorbance change vs time) were measured. The following relationship was used to calculate Kj values: (v _o -v _s )/v _s = 1/(Ki (1 + S/K _m )) for a competitive inhibitor with one binding site; or v _s /v ₀ = A + ((B-A)A + ((IC ₅₀ /(I) ⁿ ))) and

Ki = IC5o/(l + S/K _m ) for a competitive inhibitor where:

V ₀ is the velocity of the control in the absence of inhibitor; v _s is the velocity in the presence of inhibitor;

I is the concentration of inhibitor;

A is the minimum activity remaining (usually locked at zero);

B is the maximum activity remaining (usually locked at 1.0); n is the Hill coefficient, a measure of the number and cooperativity of potential inhibitor binding sites;

IC50 is the concentration of inhibitor that produces 50% inhibition under the assay conditions;

Ki is the dissociation constant of the enzyme: inhibitor complex; S is the concentration of substrate; and K _m is the Michaelis constant for the substrate.

[00211] The effectiveness of compounds of the present invention as antithrombotic agents can be determined using relevant in vivo thrombosis models, including In Vivo Electrically-induced Carotid Artery Thrombosis Models and In Vivo Rabbit Arterio-venous Shunt Thrombosis Models.

In Vivo Electrically-induced Carotid Artery Thrombosis (ECAT) Model:

[00212] The rabbit ECAT model, described by Wong et al. (J Pharmacol Exp

Ther 2000, 295, 212-218), can be used in this study. Male New Zealand White rabbits are anesthetized with ketamine (50 mg/kg + 50 mg/kg/h IM) and xylazine (10 mg/kg + 10 mg/kg/h IM). These anesthetics are supplemented as needed. An electromagnetic flow probe is placed on a segment of an isolated carotid artery to monitor blood flow. Test agents or vehicle will be given (Lv., Lp., s.c, or orally) prior to the initiation of thrombosis. Thrombus formation is induced by electrical stimulation of the carotid artery for 3 min at 4 mA using an external stainless-steel bipolar electrode. Carotid blood flow is measured continuously over a 90-min period to monitor thrombus-induced occlusion. Total carotid blood flow over 90 min is calculated by trapezoidal rule. Average carotid flow over 90 min is then determined by converting total carotid blood flow over 90 min to percent of total control carotid blood flow, which would result if control blood flow had been maintained continuously for 90 min. The ED50 (dose that increased average carotid blood flow over 90 min to 50% of the control) of compounds are estimated by a nonlinear least square regression program using the Hill sigmoid E _max equation (DeltaGraph; SPSS Inc., Chicago, IL).

In Vivo Rabbit Arterio-venous (AV) Shunt Thrombosis Model: [00213] The rabbit AV shunt model, described by Wong et al. (Wong, P. C. et al. J Pharmacol Exp Ther 2000, 292, 351-357), can be used in this study. Male New Zealand White rabbits are anesthetized with ketamine (50 mg/kg + 50 mg/kg/h IM) and xylazine (10 mg/kg + 10 mg/kg/h IM). These anesthetics are supplemented as needed. The femoral artery, jugular vein and femoral vein are isolated and catheterized. A saline-filled AV shunt device is connected between the femoral arterial and the femoral venous cannulae. The AV shunt device consists of an outer piece of tygon tubing (length = 8 cm; internal diameter = 7.9 mm) and an inner piece of tubing (length = 2.5 cm; internal diameter = 4.8 mm). The AV shunt also contains an 8-cm-long 2-0 silk thread (Ethicon, Somerville, NJ). Blood flows from the femoral artery via the AV-shunt into the femoral vein. The exposure of flowing blood to a silk thread induces the formation of a significant thrombus. Forty minutes later, the shunt is disconnected and the silk thread covered with thrombus is weighed. Test agents or vehicle will be given (Lv., Lp., s.c, or orally) prior to the opening of the AV shunt. The percentage inhibition of thrombus formation is determined for each treatment group. The ID50 values (dose which produces 50% inhibition of thrombus formation) are estimated by a nonlinear least square regression program using the Hill sigmoid E _max equation (DeltaGraph; SPSS Inc., Chicago, IL). [00214] The compounds of the present invention can be administered alone or in combination with one or more additional therapeutic agents. These other agents include, but are not limited to, other anti-coagulant or coagulation inhibitory agents, anti-platelet or platelet inhibitory agents, or thrombolytic or fibrinolytic agents. [00215] By "administered in combination" or "combination therapy" it is meant that the compound of the present invention and one or more additional therapeutic agents are administered concurrently to the mammal being treated. When administered in combination each component may be administered at the same time or sequentially in any order at different points in time. Thus, each component may be administered separately but sufficiently closely in time so as to provide the desired therapeutic effect.

Clopidogrel is an even more preferred agent. Ticlopidine and clopidogrel are also preferred compounds since they are known to be more gentle than aspirin on the gastro-intestinal tract in use.

[00219] The term thrombin inhibitors (or anti-thrombin agents), as used herein, denotes inhibitors of the serine protease thrombin. By inhibiting thrombin, various

thrombin-mediated processes, such as thrombin-mediated platelet activation (that is, for example, the aggregation of platelets, and/or the secretion of platelet granule contents including and/or serotonin) and/or fibrin formation are disrupted.

[00235] Administration of the compounds of the present invention (i.e., a first therapeutic agent) in combination with at least one additional therapeutic agent (i.e., a second therapeutic agent), preferably affords an efficacy advantage over the compounds and agents alone, preferably while permitting the use of lower doses of each. A lower dosage minimizes the potential of side effects, thereby providing an increased margin of safety. It is preferred that at least one of the therapeutic agents is administered in a sub-therapeutic dose. It is even more preferred that all of the therapeutic agents be administered in sub-therapeutic doses. Sub-therapeutic is intended to mean an amount of a therapeutic agent that by itself does not give the desired therapeutic effect for the condition or disease being treated. Synergistic combination is intended to mean that the observed effect of the combination is greater than the sum of the individual agents administered alone.

[00236] The compounds of the present invention are also useful as standard or reference compounds, for example as a quality standard or control, in tests or assays involving the inhibition of plasma kallikrein, thrombin, factor Vila, IXa, Xa and/or XIa. Such compounds may be provided in a commercial kit, for example, for use in pharmaceutical research involving plasma kallikrein, thrombin, factor Vila, IXa, Xa and/or XIa. For example, a compound of the present invention could be used as a reference in an assay to compare its known activity to a compound with an unknown activity. This would ensure the experimenter that the assay was being performed properly and provide a basis for comparison, especially if the test compound was a derivative of the reference compound. When developing new assays or protocols, compounds according to the present invention could be used to test their effectiveness. [00237] The compounds of the present invention may also be used in diagnostic assays involving plasma kallikrein, thrombin, factor Vila, IXa, Xa, and/or XIa. For example, the presence of plasma kallikrein, thrombin, factor Vila, IXa, Xa and/or XIa in an unknown sample could be determined by addition of the relevant chromogenic substrate, for example, S2288 for factor Vila, to a series of solutions containing test sample and optionally one of the compounds of the present invention. If production of pNA is observed in the solutions containing test sample, but not in

the presence of a compound of the present invention, then one would conclude factor Vila was present.

[00238] The present invention also encompasses an article of manufacture. As used herein, article of manufacture is intended to include, but not be limited to, kits and packages. The article of manufacture of the present invention, comprises: (a) a first container; (b) a pharmaceutical composition located within the first container, wherein the composition, comprises: a first therapeutic agent, comprising: a compound of the present invention or a pharmaceutically acceptable salt form thereof; and, (c) a package insert stating that the pharmaceutical composition can be used for the treatment of a thromboembolic disorder (as defined previously). In another embodiment, the package insert states that the pharmaceutical composition can be used in combination (as defined previously) with a second therapeutic agent to treat a thromboembolic disorder. The article of manufacture can further comprise: (d) a second container, wherein components (a) and (b) are located within the second container and component (c) is located within or outside of the second container. Located within the first and second containers means that the respective container holds the item within its boundaries.

[00239] The first container is a receptacle used to hold a pharmaceutical composition. This container can be for manufacturing, storing, shipping, and/or individual/bulk selling. First container is intended to cover a bottle, jar, vial, flask, syringe, tube (e.g., for a cream preparation), or any other container used to manufacture, hold, store, or distribute a pharmaceutical product. [00240] The second container is one used to hold the first container and, optionally, the package insert. Examples of the second container include, but are not limited to, boxes (e.g., cardboard or plastic), crates, cartons, bags (e.g., paper or plastic bags), pouches, and sacks. The package insert can be physically attached to the outside of the first container via tape, glue, staple, or another method of attachment, or it can rest inside the second container without any physical means of attachment to the first container. Alternatively, the package insert is located on the outside of the second container. When located on the outside of the second container, it is preferable that the package insert is physically attached via tape, glue, staple, or

another method of attachment. Alternatively, it can be adjacent to or touching the outside of the second container without being physically attached. [00241] The package insert is a label, tag, marker, etc. that recites information relating to the pharmaceutical composition located within the first container. The information recited will usually be determined by the regulatory agency governing the area in which the article of manufacture is to be sold (e.g., the United States Food and Drug Administration). Preferably, the package insert specifically recites the indications for which the pharmaceutical composition has been approved. The package insert may be made of any material on which a person can read information contained therein or thereon. Preferably, the package insert is a printable material (e.g., paper, plastic, cardboard, foil, adhesive-backed paper or plastic, etc.) on which the desired information has been formed (e.g., printed or applied).

DOSAGE AND FORMULATION [00242] The compounds of this invention can be administered in such oral dosage forms as tablets, capsules (each of which includes sustained release or timed release formulations), pills, powders, granules, elixirs, tinctures, suspensions, syrups, and emulsions. They may also be administered in intravenous (bolus or infusion), intraperitoneal, subcutaneous, or intramuscular form, all using dosage forms well known to those of ordinary skill in the pharmaceutical arts. They can be administered alone, but generally will be administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice. [00243] The dosage regimen for the compounds of the present invention will, of course, vary depending upon known factors, such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration; the species, age, sex, health, medical condition, and weight of the recipient; the nature and extent of the symptoms; the kind of concurrent treatment; the frequency of treatment; the route of administration, the renal and hepatic function of the patient, and the effect desired. A physician or veterinarian can determine and prescribe the effective amount of the drug required to prevent, counter, or arrest the progress of the thromboembolic disorder.

[00244] By way of general guidance, the daily oral dosage of each active ingredient, when used for the indicated effects, will range between about 0.001 to 1000 mg/kg of body weight, preferably between about 0.001 to 100 mg/kg of body weight per day, and most preferably between about 0.001 to 20 mg/kg/day. Intravenously, the most preferred doses will range from about 0.1 to about 10 mg/kg/minute during a constant rate infusion. Compounds of this invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three, or four times daily.

[00245] Compounds of this invention can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermal routes, using transdermal skin patches. When administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen.

[00246] The compounds are typically administered in admixture with suitable pharmaceutical diluents, excipients, or carriers (collectively referred to herein as pharmaceutical carriers) suitably selected with respect to the intended form of administration, that is, oral tablets, capsules, elixirs, syrups and the like, and consistent with conventional pharmaceutical practices.

[00247] For instance, for oral administration in the form of a tablet or capsule, the active drug component can be combined with an oral, non-toxic, pharmaceutically acceptable, inert carrier such as lactose, starch, sucrose, glucose, methyl callulose, magnesium stearate, dicalcium phosphate, calcium sulfate, mannitol, sorbitol and the like; for oral administration in liquid form, the oral drug components can be combined with any oral, non-toxic, pharmaceutically acceptable inert carrier such as ethanol, glycerol, water, and the like. Moreover, when desired or necessary, suitable binders, lubricants, disintegrating agents, and coloring agents can also be incorporated into the mixture. Suitable binders include starch, gelatin, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth, or sodium alginate, carboxymethylcellulose, polyethylene glycol, waxes, and the like. Lubricants used in these dosage forms include sodium oleate, sodium stearate, magnesium stearate, sodium benzoate,

sodium acetate, sodium chloride, and the like. Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum, and the like. [00248] The compounds of the present invention can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles, and multilamellar vesicles. Liposomes can be formed from a variety of phospholipids, such as cholesterol, stearylamine, or phosphatidylcholines. [00249] Compounds of the present invention may also be coupled with soluble polymers as targetable drug carriers. Such polymers can include polyvinylpyrrolidone, pyran copolymer, polyhydroxypropylmethacrylamide-phenol, polyhydroxyethylaspartamidephenol, or polyethyleneoxide-polylysine substituted with palmitoyl residues. Furthermore, the compounds of the present invention may be coupled to a class of biodegradable polymers useful in achieving controlled release of a drug, for example, polylactic acid, polyglycolic acid, copolymers of polylactic and polyglycolic acid, polyepsilon caprolactone, polyhydroxy butyric acid, polyorthoesters, polyacetals, polydihydropyrans, polycyanoacylates, and crosslinked or amphipathic block copolymers of hydrogels.

[00250] Dosage forms (pharmaceutical compositions) suitable for administration may contain from about 1 milligram to about 1000 milligrams of active ingredient per dosage unit. In these pharmaceutical compositions the active ingredient will ordinarily be present in an amount of about 0.1 -95% by weight based on the total weight of the composition.

[00251] Gelatin capsules may contain the active ingredient and powdered carriers, such as lactose, starch, cellulose derivatives, magnesium stearate, stearic acid, and the like. Similar diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Compressed tablets can be sugar coated or film coated to mask any unpleasant taste and protect the tablet from the atmosphere, or enteric coated for selective disintegration in the gastrointestinal tract. [00252] Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance.

[00253] In general, water, a suitable oil, saline, aqueous dextrose (glucose), and related sugar solutions and glycols such as propylene glycol or polyethylene glycols are suitable carriers for parenteral solutions. Solutions for parenteral administration preferably contain a water soluble salt of the active ingredient, suitable stabilizing agents, and if necessary, buffer substances. Antioxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid, either alone or combined, are suitable stabilizing agents. Also used are citric acid and its salts and sodium EDTA. In addition, parenteral solutions can contain preservatives, such as benzalkonium chloride, methyl-or propyl-paraben, and chlorobutanol. [00254] Suitable pharmaceutical carriers are described in Remington's

Pharmaceutical Sciences, Mack Publishing Company, a standard reference text in this field.

[00255] Where the compounds of this invention are combined with other anticoagulant agents, for example, a daily dosage may be about 0.1 to 100 milligrams of the compound of the present invention and about 0.1 to 7.5 milligrams of the second anticoagulant, per kilogram of patient body weight. For a tablet dosage form, the compounds of this invention generally may be present in an amount of about 5 to 100 milligrams per dosage unit, and the second anti-coagulant in an amount of about 1 to 50 milligrams per dosage unit. [00256] Where the compounds of the present invention are administered in combination with an anti -platelet agent, by way of general guidance, typically a daily dosage may be about 0.01 to 25 milligrams of the compound of the present invention and about 50 to 150 milligrams of the anti-platelet agent, preferably about 0.1 to 1 milligrams of the compound of the present invention and about 1 to 3 milligrams of antiplatelet agents, per kilogram of patient body weight.

[00257] Where the compounds of the present invention are administered in combination with thrombolytic agent, typically a daily dosage may be about 0.1 to 1 milligrams of the compound of the present invention, per kilogram of patient body weight and, in the case of the thrombolytic agents, the usual dosage of the thrombolyic agent when administered alone may be reduced by about 50-80% when administered with a compound of the present invention.

[00258] Where two or more of the foregoing second therapeutic agents are administered with the compound of the present invention, generally the amount of each component in a typical daily dosage and typical dosage form may be reduced relative to the usual dosage of the agent when administered alone, in view of the additive or synergistic effect of the therapeutic agents when administered in combination.

[00259] Particularly when provided as a single dosage unit, the potential exists for a chemical interaction between the combined active ingredients. For this reason, when the compound of the present invention and a second therapeutic agent are combined in a single dosage unit they are formulated such that although the active ingredients are combined in a single dosage unit, the physical contact between the active ingredients is minimized (that is, reduced). For example, one active ingredient may be enteric coated. By enteric coating one of the active ingredients, it is possible not only to minimize the contact between the combined active ingredients, but also, it is possible to control the release of one of these components in the gastrointestinal tract such that one of these components is not released in the stomach but rather is released in the intestines. One of the active ingredients may also be coated with a material that affects a sustained-release throughout the gastrointestinal tract and also serves to minimize physical contact between the combined active ingredients. Furthermore, the sustained-released component can be additionally enteric coated such that the release of this component occurs only in the intestine. Still another approach would involve the formulation of a combination product in which the one component is coated with a sustained and/or enteric release polymer, and the other component is also coated with a polymer such as a low viscosity grade of hydroxypropyl methylcellulose (HPMC) or other appropriate materials as known in the art, in order to further separate the active components. The polymer coating serves to form an additional barrier to interaction with the other component. [00260] These as well as other ways of minimizing contact between the components of combination products of the present invention, whether administered in a single dosage form or administered in separate forms but at the same time by the same manner, will be readily apparent to those skilled in the art, once armed with the present disclosure.
