FIELD OF THE INVENTION

[0002] The present invention relates to novel macrocyclic factor Vila inhibitors and pharmaceutical compositions thereof. 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, 81 :734-744 (1993)). 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. et al, Blood Coag. FibrinoL, 4:281-292 (1993)). 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, 17:S 1-S5 (2003)). 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. Set, 96:231 1-2315 (1999); Himber, J. et al, J. Thromb. Haemost., 1 :889-895 (2003)). 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., 1 :878-880 (2003)).

[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, 105:453-463 (2005)).

[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. et al., Curr. Opin. Pharmacol, 1 : 159-163 (2001); Lazarus, R.A. et al, Curr. Med. Chem., 11 :2275-2290 (2004); Frederick, R. et al, Curr. Med. Chem., 12:397-417 (2005).) 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 XK1, 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, 14: 113-121 (2002)). 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, 306: 11 15-1 121 (2003); Olivero, A.G. et al., J. Biol. Chem., 280:9160-9169 (2005); Young, W.B. et al, Bioorg. Med. Chem. Lett, 16:2037-2041 (2006); Zbinden, K.G. et al, Bioorg. Med. Chem., 14:5357-5369 (2006)) and venous thrombosis (Szalony, J.A. et al, Thrombosis Research, 112: 167-174 (2003); Arnold, C.S. et al, Thrombosis Research, 1 17:343-349 (2006)), 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, 104:74-78 (2001)), reduces systemic thrombin generation in patients undergoing coronary angioplasty (Moons, A.H.M., J. Am. Coll. Cardiol, 41 :2147-2153 (2003)), and reduces magnitude and duration of ischemic events in patients with acute coronary syndromes (Giugliano, R.P. et al, World Congress of Cardiology, Barcelona, Poster #3897 (2006)).

It is also understood that each individual element of the embodiments is its own independent 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. III. CHEMISTRY

[0047] Throughout the specification and the appended claims, a given chemical formula or name shall encompass all stereo and optical isomers and racemates thereof where such isomers exist. Unless otherwise indicated, all chiral (enantiomeric and diastereomeric) and racemic forms are within the scope of the invention. Many geometric isomers of C=C double bonds, C=N double bonds, ring systems, and the like can also be present in the compounds, and all such stable isomers are contemplated in the present invention. Cis- and trans- (or E- and Z-) 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. The present compounds can be isolated in optically active or racemic forms. Optically active forms may be prepared by resolution of racemic forms or by synthesis from optically active 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 may be separated by conventional methods, for example, by

chromatography or fractional crystallization. Depending on the process conditions the end products of the present invention are obtained either in free (neutral) or salt form. Both the free form and the salts of these end products are within the scope of the invention. If so desired, one form of a compound may be converted into another form. A free base or acid may be converted into a salt; a salt may be converted into the free compound or another salt; a mixture of isomeric compounds of the present invention may be separated into the individual isomers. Compounds of the present invention, free form 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.

[0048] As used herein, the term "alkyl" or "alkylene" is intended to include both branched and straight-chain saturated aliphatic hydrocarbon groups having the specified number of carbon atoms. For example, "C\ to C6 alkyl" or "Ci_6 alkyl" (or alkylene), is intended to include Ci , C2, C3, C4, C5, and C5 alkyl groups. Alkyl group can be unsubstituted or substituted with at least one hydrogen being replaced by another chemical group. Example alkyl groups include, but are not limited to, methyl (Me), ethyl (Et), propyl (e.g., n-propyl and isopropyl), butyl (e.g., n-butyl, isobutyl, ?-butyl), and pentyl (e.g., n-pentyl, isopentyl, neopentyl).

[0049] The term "alkoxy" or "alkyloxy" refers to an -O-alkyl group. "Ci to C5 alkoxy" or "Ci .5 alkoxy" (or alkyloxy), is intended to include Ci , C2, C3, C4, C5, and C5 alkoxy groups. Example alkoxy groups include, but are not limited to, methoxy, ethoxy, propoxy (e.g., n-propoxy and isopropoxy), and ?-butoxy. Similarly, "alkylthio" or "thioalkoxy" represents an alkyl group as defined above with the indicated number of carbon atoms attached through a sulphur bridge; for example methyl-S- and ethyl-S-.

[0050] "Halo" or "halogen" includes fluoro, chloro, bromo, and iodo.

[0051] The term "counter ion" is used to represent a negatively charged species such as chloride, bromide, hydroxide, acetate, and sulfate.

[0052] As referred to herein, the term "substituted" means that at least one hydrogen atom is replaced with a non-hydrogen group, provided that normal valencies are maintained 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. Keto substituents are not present on aromatic moieties. 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 carbonyl group or double bond be part (i.e., within) of 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).

[0053] 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→0) derivative.

[0054] When any variable occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-3 R groups, then said group may optionally be substituted with up to three R groups, and at each occurrence R is selected independently from the definition of R.

[0055] Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds. [0056] 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 in 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.

[0057] The phrase "pharmaceutically acceptable" is employed herein to refer to those compounds, materials, compositions, and/or dosage forms that 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, and/or other problem or complication, commensurate with a reasonable benefit/risk ratio.

[0058] 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.

[0059] The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound that 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 Edition, Mack Publishing Company, Easton, PA (1990), the disclosure of which is hereby incorporated by reference.

[0060] 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:

[0061] Compounds containing a carboxy group can form physiologically

hydrolyzable esters that 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 Ci to C alkyl, Ci to C5 alkylbenzyl, 4-methoxybenzyl, indanyl, phthalyl, methoxymethyl,

SYNTHESIS [0067] 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 or solvent mixture 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.

[0068] 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 et al. (Protective Groups In Organic Synthesis, 3rd Edition, Wiley- Interscience (1999)). [0069] Compounds having the general Formula (I) can be prepared according to the general methods shown in the Schemes below. Compounds of formula (I) can be prepared using the general method shown in Scheme 1. Using the Petasis boronic acid Mannich reaction (Petasis, N.A. et al, J. Am. Chem. Soc, 1 19:445-446 (1997); Petasis, N.A. et al, Tetrahedron, 53: 16463-16470 (1997)), amines 1 are reacted with glyoxylic acid and phenyl boronic acids 2 to afford arylglycines 3. Aryl glycines 3 in turn are coupled with amines 4 to afford amino alcohol amides 5. Treatment of amides 5 with phosgene (or a phosgene equivalent such as triphosgene) to generate the carbamic chloride intermediate in situ, followed by slow addition of this intermediate into a basic reaction mixture, such as triethylamine or Hunig's base in DCM or acetonitrile, effects macrocyclization to yield compounds 6 of formula (I) after protecting group manipulation if necessary. [0070] Petasis boronic acid Mannich reaction is typically conducted in a solvent such as, but not limited to, toluene, dichloromethane, 1,2-dichloroethane, methanol, ethanol, dimethylformamide, or acetonitrile, or appropriate mixtures thereof. In some cases, mixtures of acetonitrile and dimethylformamide are preferred. Fluorinated alcohols such as hexafluoroisopropanol are useful additives that may improve the rate and or yield of the reaction. If necessary, the reaction is heated conventionally or in a microwave reactor to achieve a practical reaction rate.

[0071] The preparation of amines 1 is described in the experimental procedures for Intermediates 1-4. Preparation of phenylboronic acids 2 is described in the synthesis of Intermediate 5 and in examples. Additionally, preparation of phenylboronic acids 2 can be achieved through methods known to one skilled in the art of organic synthesis.

The preparation of amines 4 is described in the experimental procedures for Intermediates 6, 8 and in the examples. Additionally, preparation of N-methylated benzylamines 4 can be achieved through methods known to one skilled in the art of organic synthesis.

[0072] Coupling reagents and conditions can be found in Bodanszky, Principles of Peptide Synthesis, Second Edition, Springer Verlag Ed, Berlin (1993) and in a recent review (Montalbetti, C.A.G.N. et al, Tetrahedron, 61 : 10819-11046 (2005)). Coupling reagents include, but not limited to, CDI, DIC, and EDCI. Optionally, an intermediate activated ester can be prepared by adding one equivalent of 1 -hydroxybenzotriazole or 1 - hydroxy-7-azabenzotriazole. Other coupling reagents include, but not limited to, BOP or HATU, which are usually reacted in the presence of a tertiary base such as DIEA or TEA. BOP is a preferred reagent for preparation of compounds of Formula (I). Addition of catalytic or stoichiometric DMAP may improve the reaction rate or yield. The reaction may be conducted in solvents such as, but not limited to, DCE, DCM, DMF, or mixtures thereof. Finally, it may be necessary to run the macrocyclization reaction under dilute conditions (initial concentration of 4 < 0.1 M) to favor macrocyclization over

dimerization. Depending on the particular substituent groups present in the final compounds, deprotection steps may be required before or after the macrocyclization step to afford compounds of Formula (I). cheme 1

[0073] Compounds of formula (I) can also be prepared using the general method shown in Scheme 2. Using the Petasis boronic acid Mannich reaction, amines 1 are reacted with glyoxylic acid and elaborated phenyl boronic acids 7 to afford arylglycines 8. The protecting group PG in 8, for instance, a carbamate such as Cbz, may be deprotected by catalytic hydrogenation to an N-methylated benzylamine 9. Amino acids 9 can be cyclized to macrocycles 6 by slow addition of this intermediate into a mixture of base such as triethylamine or Hunig's base and coupling reagent such as BOP in DCM or acetonitrile. After a final protecting group manipulation, compounds of formula (I) are obtained.

[0074] Preparation of the elaborated phenyl boronic acids 7 is described in Scheme 3. Treatment of amines 11 with phosgene (or a phosgene equivalent such as triphosgene) to generate the carbamic chloride intermediate in situ, followed by addition of this intermediate into a reaction mixture of aryl bromides 10 and base, such as triethylamine or Hunig's base in DCM or acetonitrile, affords carbamates 12. The bromide in carbamates 12 is converted to the boronic acids 7 by the Suzuki-Miyara coupling (Miyaura, N. et al, Chem. Rev., 95:2457 (1995)).

III. BIOLOGY

[0078] 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 cerebrovascular 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 are not limited to: cardiopulmonary bypass, percutaneous coronary intervention, and hemodialysis.

[0079] 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 coagulation factor Vila.

[0080] 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.

[0081] Compounds of the present invention may additionally be useful as diagnostic agents and adjuncts. For example, the present compounds may be useful in maintaining the reactivity of fractionated whole blood containing platelets such as required for analytical and biological testing or transfusions. In addition, the compounds of the present invention may be useful for maintaining blood vessel patency in conjunction with vascular surgery including bypass grafting, arterial reconstruction, atherectomy, vascular graft and stent patency, organ, tissue and cell implantation and transplantation. In addition, the compounds of the present invention may be useful for maintaining blood vessel patency in conjunction with interventional cardiology or vascular surgery including bypass grafting, arterial reconstruction, atherectomy, vascular graft and stent patency, organ, tissue and cell implantation and transplantation.

[0082] It is also desirable and preferable to find compounds with advantageous and improved characteristics compared with known anti-atherosclerosis agents, in one or more of the following categories that 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 that decrease blood drug 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) improved therapeutic index.

[0083] As used herein, the term "patient" encompasses all mammalian species.

[0084] As used herein, the term "subject" refers to any human or non-human organism that could potentially benefit from treatment with an anti-atherosclerosis agent, e.g., an endothelial lipase inhibitor. Exemplary subjects include human beings of any age with risk factors for atherosclerosis and its associated coronary artery disease. Common risk factors include, but are not limited to, age, sex, weight, and family history.

[0085] As used herein, "treating" or "treatment" cover the treatment of a disease-state in a mammal, particularly in a human, and include: (a) inhibiting the disease-state, i.e., arresting it development; and/or (b) relieving the disease-state, i.e., causing regression of the disease state.

[0086] As used herein, "prophylaxis" or "prevention" covers the preventive treatment of a subclinical disease-state in a mammal, particularly in a human, aimed at reducing the probability of the occurrence of a clinical disease-state. Patients are selected for preventative therapy based on factors that are known to increase risk of suffering a clinical disease state compared to the general population. "Prophylaxis" therapies can be divided into (a) primary prevention and (b) secondary prevention. Primary prevention is defined as treatment in a subject that has not yet presented with a clinical disease state, whereas secondary prevention is defined as preventing a second occurrence of the same or similar clinical disease state.

[0087] As used herein, "risk reduction" covers therapies that lower the incidence of development of a clinical disease state. As such, primary and secondary prevention therapies are examples of risk reduction.

[0088] "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 to inhibit endothelial lipase and/or to prevent or treat the disorders listed herein. When applied to a combination, the term refers to combined amounts of the active ingredients that result in the preventive or therapeutic effect, whether administered in combination, serially, or simultaneously.

A. In Vitro Assays

[0089] The effectiveness of compounds of the present invention as inhibitors of the coagulation Factors, Vila, IXa, Xa, XIa, Xlla, plasma kallikrein or thrombin, tissue kallikrein and activated protein C, can be determined using a relevant purified serine protease, respectively, and an appropriate synthetic substrate. The rate of hydrolysis of the chromogenic or fluorogenic 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 of pNA (para nitroaniline), which was monitored spectrophotometrically by measuring the increase in absorbance at 405 nm, or the release of AMC (amino methylcoumarin), 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 or fluorescence change 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 the inhibitory constant, Kj. a. FVIIa Ki (25 °C): FVIIa Peptide Substrate Assay

[0090] S2288 (range of concentrations) and FVIIa inhibitor were incubated for 15 minutes (min) at 25 °C. Reactions were initiated by addition of a solution of full-length human TF (6 nM), FVIIa (0.75 nM), and PCPS (25 μΜ). FVIIa hydrolyses S2288, which was monitored for up to 60 min at 405 nm. Steady-state reaction velocity data (vs) was globally fit to Equation 1 for competitive inhibition. vs = Vmax[S]/([S]+Km(l+[I]/Ki)) (Eq. 1) where Vmax is maximum velocity, [S] is substrate concentration, Km is the Michaelis- Menten constant, [I] is the inhibitor concentration, and Ki is the inhibitor dissociation constant (GraFit, version 5, Erithacus Software Ltd, West Sussex, UK).

[0091] FVIIa-Xase Ki (37 °C): S2765 (0.5 mM), PCPS (25 μΜ), calcium chloride (5 mM), full-length human TF (3 nM), human FVIIa (5 pM), and FVIIa inhibitor were incubated for 15 min at 37 °C. Reactions were initiated by the addition of human FX

(range of concentrations). Preliminary experiments revealed that the plasma purified FX contains a residual amount of human FVIIa which could not be removed by affinity chromatography. The residual FVIIa is sufficient, when combined with PCPS, calcium and TF to catalyze the conversion of FX to Xa, and was increased by the addition of 5 pM human FVIIa. FXa in turn hydrolyses S2765, which was monitored for 60 min at 405 nm. FXase activity was derived from the parabolic change in absorbance over time according to Equation 2:

Absorbance = ½ at 2 + bt + c (Eq. 2) where a is proportional to the rate of FX activation≡ product≡ vs; b is proportional to the hydrolysis of S2765 in the absence of FXa; c is the absorbance at t = 0. Steady-state reaction velocity data (vs) was globally fit to Equation 3 for non-competitive inhibition modified for contaminating enzyme (FVIIa) in the substrate (FX) as vs = (kcat(E+f[S]) / ((Km +[S])(1+[I]/ Ki)) (Eq. 3) where kcat is the enzyme turnover rate, E is the concentration of enzyme added, f is the molar fraction of enzyme contained in the substrate, and the rest as defined above.

[0092] Factor IXa determinations were made in 0.005 M calcium chloride, 0.1 M sodium chloride, 0.0000001 M Refludan (Berlex), 0.05 M TRIS base and 0.5% PEG 8000 at a pH of 7.4. Refludan was added to inhibit small amounts of thrombin in the commercial preparations of human Factor IXa. 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-Ph'Gly-Arg-AMC; CenterChem) at a concentration of 0.0004-0.0005 M.

[0093] Factor Xa determinations were made in 0.1 M sodium phosphate buffer at a pH of 7.5 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 0.0002-0.00035 M.

Determinations were made using purified human kallikrein (Enzyme Research

[0097] Thrombin determinations were made in 0.1 M sodium phosphate buffer at a pH of 7.5 containing 0.2 M sodium chloride and 0.5% PEG 8000.

[0098] Tissue kallikrein- 1 activity was determined in reactions containing 0.05 nM enzyme and 90 μΜ substrate (H-D-Val-Leu-Arg-AFC) in buffer (0.1M sodium phosphate pH 7.4, 0.2 M NaCl, 0.5% PEG 8000, and 1% DMSO). Assays were performed using 96- well microtiter plates (COSTAR® 3600, CORNING®, NY, USA) and a thermostatic temperature controlled plate reader (SPECTRAMAX® Gemini, Molecular Devices, Sunnyvale, CA, USA). Fluorescence was monitored using 400 nm excitation and 505 nm emission wavelengths.

[0099] APC activity was determined in reactions containing 0.05 nM enzyme and 90 μΜ substrate (pyroGlu-Pro-Arg-pNA) in buffer (0.1M sodium phosphate pH 7.4, 0.2 M NaCl, 0.5%) PEG 8000, and 1%> DMSO). Assays were performed using 96-well microtiter plates (COSTAR® 3600, CORNING®, NY, USA) and a thermostatic temperature controlled plate reader (SPECTRAMAX® Gemini, Molecular Devices, Sunnyvale, CA, USA). Fluorescence was monitored using 400 nm excitation and 505 nm emission wavelengths.

[00100] The Michaelis constant, K _m , for substrate hydrolysis by each protease, was determined at 25 °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 or fluorescence change versus time) were measured. The following relationships were used to calculate Kj values:

(v ₀ -v _s )/v _s = I/(Kj(l + S/K _m )) for a competitive inhibitor with one binding site; or v _s /v ₀ = A + ((B-A)/l + ((IC ₅₀ /(I) _n ))); and

Kj = IC5Q (1 + 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;

Kj 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. [00101] The selectivity of a compound may be evaluated by taking the ratio of the Kj value for a given protease with the Kj value for the protease of interest (i.e., selectivity for FVIIa versus protease P = Kj for protease P/ Kj 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.

[00102] The effectiveness of compounds of the present invention as inhibitors of coagulation can be determined using a standard or modified clotting assay. An increase in the plasma clotting time in the presence of inhibitor is indicative of anticoagulation. Relative clotting time is the clotting time in the presence of an inhibitor divided by the clotting time in the absence of an inhibitor. The results of this assay may be expressed as IC1.5x or IC2x, the inhibitor concentration required to increase the clotting time by 50 or 100 percent, respectively. The IC1.5x or IC2x is found by linear interpolation from relative clotting time versus inhibitor concentration plots using inhibitor concentration that spans the IC1.5x or IC2x.

[00103] Clotting times are determined using citrated normal human plasma as well as plasma obtained from a number of laboratory animal species (e.g., rat, or rabbit). A compound is diluted into plasma beginning with a 10 mM DMSO stock solution. The final concentration of DMSO is less than 2%. Plasma clotting assays are performed in an automated coagulation analyzer (Sysmex, Dade-Behring, Illinois). Similarly, clotting times can be determined from laboratory animal species or humans dosed with compounds of the invention.

[00104] Prothrombin Time (PT) is determined using thromboplastin (Thromboplastin C Plus, Dade-Behring, Illinois) following the directions in the package insert. Plasma (0.05 mL) is warmed to 37 °C for 1 minute. Thromboplastin (0.1 mL) is added to the plasma to initiate coagulation. The clotting time is the time in seconds from the moment thromboplastin is added until a clot is detected.

[00105] Deficient FVII-PT (FVII-def PT) was performed by mixing human FVII immunodepleted plasma with normal pooled plasma from different species to produce a clotting time of about 40 seconds (s). For PT and FVII-def PT, plasma (50 μΐ) was warmed to 37 °C for 3 min before adding PT reagent (100 μΐ). Determinations were performed in duplicate and expressed as a mean ratio of treated vs. baseline control. The concentrations required to prolong clotting time by two-fold (EC2x) were calculated by linear interpolation (Microsoft Excel, Redmond, WA, USA) and are expressed as total plasma concentrations, not final assay concentrations after addition of clotting assay reagents.

[00106] Activated Partial Thromboplastin Time (aPTT) is determined using

ALEXIN® (Trinity Biotech, Ireland) or ACTIN® (Dade-Behring, Illinois) following the directions in the package insert. Plasma (0.05 mL) is warmed to 37 °C for 1 minute.

ALEXIN® or ACTIN® (0.05 mL) is added to the plasma and incubated for an additional 2 to 5 minutes. Calcium chloride (25 mM, 0.05 mL) is added to the reaction to initiate coagulation. The clotting time is the time in seconds from the moment calcium chloride is added until a clot is detected. B. In Vivo Assays

[00107] 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. a. In Vivo Electrically-induced Carotid Artery Thrombosis (ECAT) Model

[00108] The rabbit ECAT model, described by Wong et al. (J. Pharmacol. Exp. Ther., 295:212-218 (2000)), 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 (i.v., i.p., s.c, or orally) prior to or after the initiation of thrombosis. Drug treatment prior to initiation of thrombosis is used to model the ability of test agents to prevent and reduce the risk of thrombus formation, whereas dosing after initiation is used to model the ability to treat existing thrombotic disease. 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 the 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). b. In Vivo Rabbit Arterio-venous (AV) Shunt Thrombosis Model

[00109] The rabbit AV shunt model, described by Wong et al. (Wong, P.C. et al, J. Pharmacol. Exp. Ther., 292:351-357 (2000)), 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 (i.v., i.p., 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 ID5Q values (dose that 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).

VI. PHARMACEUTICAL COMPOSITIONS, FORMULATIONS AND

COMBINATIONS

[00110] The compounds of this invention can be administered for any of the uses described herein by any suitable means, for example, orally, such as tablets, capsules (each of which includes sustained release or timed release formulations), pills, powders, granules, elixirs, tinctures, suspensions, syrups, and emulsions; sublingually; bucally; parenterally, such as by subcutaneous, intravenous, intramuscular, or intrasternal injection, or infusion techniques (e.g., as sterile injectable aqueous or non-aqueous solutions or suspensions); nasally, including administration to the nasal membranes, such as by inhalation spray; topically, such as in the form of a cream or ointment; or rectally such as in the form of suppositories. 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.

[00111] The term "pharmaceutical composition" means a composition comprising a compound of the invention in combination with at least one additional pharmaceutically acceptable 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, anti-fungal 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 Edition (1990).

[00112] 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.

[00113] By way of general guidance, the daily oral dosage of each active ingredient, when used for the indicated effects, will range between about 0.01 to about 5000 mg per day, preferably between about 0.1 to about 1000 mg per day, and most preferably between about 0.1 to about 250 mg per day. Intravenously, the most preferred doses will range from about 0.01 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.

[00114] 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, e.g., oral tablets, capsules, elixirs, and syrups, and consistent with conventional pharmaceutical practices.

[00115] Dosage forms (pharmaceutical compositions) suitable for administration may contain from about 1 milligram to about 2000 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.

[00116] A typical capsule for oral administration contains at least one of the compounds of the present invention (250 mg), lactose (75 mg), and magnesium stearate (15 mg). The mixture is passed through a 60 mesh sieve and packed into a No. 1 gelatin capsule.

[00117] A typical injectable preparation is produced by aseptically placing at least one of the compounds of the present invention (250 mg) into a vial, aseptically freeze-drying and sealing. For use, the contents of the vial are mixed with 2 mL of physiological saline, to produce an injectable preparation.

[00118] The present invention includes within its scope pharmaceutical compositions comprising, as an active ingredient, a therapeutically effective amount of at least one of the compounds of the present invention, alone or in combination with a pharmaceutical carrier. Optionally, compounds of the present invention can be used alone, in

combination with other compounds of the invention, or in combination with one or more, preferably one to three, other therapeutic agent(s), e.g., other anti-platelet agents or other pharmaceutically active material. Additionally, the present compounds may be used in combination with one or more of various other therapeutic agents, including: anti- arrhythmic agents; anti-hypertensive agents; anti-thrombotic and/or anti-thrombolytic agents; calcium channel blockers (L-type and T-type); cardiac glycosides; diuretics, mineralocorticoid receptor antagonists; phospodiesterase inhibitors; cholesterol/lipid lowering agents and lipid profile therapies; anti-diabetic agents; anti-depressants; antiinflammatory agents (steroidal and non-steroidal); anti-osteoporosis agents; hormone replacement therapies; oral contraceptives; anti-coagulants; anti-obesity agents; antianxiety agents; anti-proliferative agents; anti-tumor agents; anti-ulcer and

gastroesophageal reflux disease agents; growth hormone and/or growth hormone secretagogues; thyroid mimetics (including thyroid receptor antagonist); anti-infective agents; anti-viral agents; anti-bacterial agents; and anti-fungal agents.

[00119] The above other therapeutic agents, when employed in combination with the compounds of the present invention may be used, for example, in those amounts indicated in the Physicians' Desk Reference, as in the patents set out above, or as otherwise determined by one of ordinary skill in the art.

[00120] 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.

[00121] 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.

[00122] The compounds of the present invention can be administered alone or in combination with one or more, preferably one to three, additional therapeutic agents. By "administered in combination" or "combination therapy" it is meant that the compound of the present invention and one or more, preferably one to three, 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.

[00123] 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 endothelial lipase. Such compounds may be provided in a commercial kit, for example, for use in pharmaceutical research involving P2Yi or anti-platelet activity.

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.

[00124] Other features of the invention should become apparent in the course of the above descriptions of exemplary embodiments that are given for illustration of the invention and are not intended to be limiting thereof.
