Description

NOVEL MACROCYCLES AS FACTOR XIA INHIBITORS

FIELD OF THE INVENTION

[0001] The present invention relates generally to novel macrocyclic compounds, and their analogues thereof, which are inhibitors of factor XIa and/or plasma kallikrein, compositions containing them, and methods of using them, for example, for the treatment or prophylaxis of thromboembolic disorders.

BACKGROUND OF THE INVENTION

[0002] Thromboembolic diseases remain the leading cause of death in developed countries despite the availability of anticoagulants such as warfarin (COUMADIN®), heparin, low molecular weight heparins (LMWH), and synthetic pentasaccharides and antiplatelet agents such as aspirin and clopidogrel (PLAVIX®). The oral anticoagulant warfarin, inhibits the post-translational maturation of coagulation factors VII, IX, X and prothrombin, and has proven effective in both venous and arterial thrombosis. However, its usage is limited due to its narrow therapeutic index, slow onset of therapeutic effect, numerous dietary and drug interactions, and a need for monitoring and dose adjustment. Thus discovering and developing safe and efficacious oral anticoagulants for the prevention and treatment of a wide range of thromboembolic disorders has become increasingly important.

[0003] One approach is to inhibit thrombin generation by targeting the inhibition of coagulation factor XIa (FXIa). Factor XIa is a plasma serine protease involved in the regulation of blood coagulation, which is initiated in vivo by the binding of tissue factor (TF) to factor VII (FVII) to generate factor Vila (FVIIa). The resulting TF:FVIIa complex activates factor IX (FIX) and factor X (FX) that leads to the production of factor Xa (FXa). The generated FXa catalyzes the transformation of prothrombin into small amounts of thrombin before this pathway is shut down by tissue factor pathway inhibitor (TFPI). The process of coagulation is then further propagated via the feedback activation of Factors V, VIII and XI by catalytic amounts of thrombin. (Gailani, D. et al.,

Arterioscler. Thromb. Vase. Biol., 27:2507-2513 (2007).) The resulting burst of thrombin converts fibrinogen to fibrin that 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:S1-S5 (2003)). Therefore, factor XIa plays a key role in propagating this amplification loop and is thus an attractive target for anti-thrombotic therapy. SUMMARY OF THE INVENTION

[0004] The present invention provides novel macrocyclic compounds, their analogues, including stereoisomers, tautomers, pharmaceutically acceptable salts, or solvates thereof, which are useful as selective inhibitors of serine protease enzymes, especially factor XIa and/or plasma kallikrein.

[0005] The present invention also provides processes and intermediates for making the compounds of the present invention.

[0006] The present invention also provides pharmaceutical compositions comprising a pharmaceutically acceptable carrier and at least one of the compounds of the present invention or stereoisomers, tautomers, pharmaceutically acceptable salts, or solvates thereof.

[0007] The compounds of the invention may be used in the treatment and/or prophylaxis of thromboembolic disorders.

[0008] The compounds of the present invention may be used in therapy.

[0009] The compounds of the present invention may be used for the manufacture of a medicament for the treatment and/or prophylaxis of a thromboembolic disorder.

[0010] The compounds of the invention can be used alone, in combination with other compounds of the present invention, or in combination with one or more, preferably one to two, other agent(s).

[0011] These and other features of the invention will be set forth in expanded form as the disclosure continues.

III. CHEMISTRY [00143] 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.

[00144] The term "stereoisomer" refers to isomers of identical constitution that differ in the arrangement of their atoms in space. Enantiomers and diastereomers are examples of stereoisomers. The term "enantiomer" refers to one of a pair of molecular species that are mirror images of each other and are not superimposable. The term "diastereomer" refers to stereoisomers that are not mirror images. The term "racemate" or "racemic mixture" refers to a composition composed of equimolar quantities of two enantiomeric species, wherein the composition is devoid of optical activity.

A bridged ring occurs when one or more carbon atoms link two non-adjacent carbon atoms. Preferred bridges are one or two carbon atoms. 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.

[00157] As used herein, the term "bicyclic carbocycle" or "bicyclic carbocyclic group" is intended to mean a stable 9- or 10-membered carbocyclic ring system that contains two fused rings and consists of carbon atoms.

The nitrogen atom may be substituted or unsubstituted (i.e., N or NR wherein R is H or another substituent, if defined). The heterocyclic ring may be attached to its pendant group at any heteroatom or carbon atom that results in a stable structure. The heterocyclic rings described herein may be substituted on carbon or on a nitrogen atom if the resulting compound is stable. A nitrogen in the heterocycle may optionally be quaternized. It is preferred that when the total number of S and O atoms in the heterocycle exceeds 1 , then these heteroatoms are not adjacent to one another. It is preferred that the total number of S and O atoms in the heterocycle is not more than 1. When the term "heterocycle" is used, it is intended to include heteroaryl.

[00165] As used herein, the term "bicyclic heterocycle" or "bicyclic heterocyclic group" is intended to mean a stable 9- or 10-membered heterocyclic ring system which contains two fused rings and consists of carbon atoms and 1, 2, 3, or 4 heteroatoms independently selected from the group consisting of N, O and S. Of the two fused rings, one ring is a 5- or 6-membered monocyclic aromatic ring comprising a 5-membered heteroaryl ring, a 6-membered heteroaryl ring or a benzo ring, each fused to a second ring. The second ring is a 5- or 6-membered monocyclic ring which is saturated, partially unsaturated, or unsaturated, and comprises a 5-membered heterocycle, a 6-membered heterocycle or a carbocycle (provided the first ring is not benzo when the second ring is a carbocycle).

[00166] The bicyclic heterocyclic group may be attached to its pendant group at any heteroatom or carbon atom which results in a stable structure. The bicyclic heterocyclic group described herein may be substituted on carbon or on a nitrogen atom if the resulting compound is stable. It is preferred that when the total number of S and O atoms in the heterocycle exceeds 1, then these heteroatoms are not adjacent to one another. It is preferred that the total number of S and O atoms in the heterocycle is not more than 1. Examples of a bicyclic heterocyclic group are, but not limited to, quinolinyl,

isoquinolinyl, phthalazinyl, quinazolinyl, indolyl, isoindolyl, indolinyl, lH-indazolyl, benzimidazolyl, 1 ,2,3,4-tetrahydroquinolinyl, 1 ,2,3,4-tetrahydroisoquinolinyl,

1 ,2,3 ,4-tetrahydro-quinoxalinyl, and 1 ,2,3 ,4-tetrahydro-quinazolinyl.

[00167] As used herein, the term "aromatic heterocyclic group" or "heteroaryl" is intended to mean stable monocyclic and polycyclic aromatic hydrocarbons that include at least one heteroatom ring member such as sulfur, oxygen, or nitrogen. Heteroaryl groups include, without limitation, pyridyl, pyrimidinyl, pyrazinyl, pyridazinyl, triazinyl, furyl, quinolyl, isoquinolyl, thienyl, imidazolyl, thiazolyl, indolyl, pyrroyl, oxazolyl, benzofuryl, benzothienyl, benzthiazolyl, isoxazolyl, pyrazolyl, triazolyl, tetrazolyl, indazolyl, 1,2,4-thiadiazolyl, isothiazolyl, purinyl, carbazolyl, benzimidazolyl, indolinyl, benzodioxolanyl, and benzodioxane.

The nitrogen and sulfur heteroatoms may optionally be oxidized (i.e., N→0 and S(0)_p, wherein p is 0, 1 or 2).

[00168] Bridged rings are also included in the definition of 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. Examples of bridged rings 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.

[00169] The term "counterion" is used to represent a negatively charged species such as chloride, bromide, hydroxide, acetate, and sulfate.

[00170] When a dotted ring is used within a ring structure, this indicates that the ring structure may be saturated, partially saturated or unsaturated.

[00171] 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).

[00172] 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.

[00173] 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. Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

[00174] 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.

[00175] 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.

[00176] 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.

[00177] 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.

[00178] 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:

[00179] 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_₆alkyl, Ci_₆alkylbenzyl,

4-methoxybenzyl, indanyl, phthalyl, methoxymethyl, Ci_₆ alkanoyloxy-Ci_₆alkyl (e.g. , acetoxymethyl, pivaloyloxymethyl or propionyloxymethyl),

Ci_₆alkoxycarbonyloxy-Ci_₆alkyl (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. [00180] Preparation of prodrugs is well known in the art and described in, for example, King, F.D., ed., Medicinal Chemistry: Principles and Practice, The Royal Society of Chemistry, Cambridge, UK (1994); Testa, B. et al, Hydrolysis in Drug and Prodrug Metabolism. Chemistry, Biochemistry and Enzymology, VCHA and Wiley-VCH, Zurich, Switzerland (2003); Wermuth, C.G., ed., The Practice of Medicinal Chemistry, Academic Press, San Diego, CA (1999).

[00181] The present invention is intended to include all isotopes of atoms occurring in the present compounds. Isotopes include those atoms having the same atomic number but different mass numbers. By way of general example and without limitation, isotopes of hydrogen include deuterium and tritium. Isotopes of carbon include ¹³C and ¹⁴C.

Isotopically-labeled compounds of the invention can generally be prepared by

conventional techniques known to those skilled in the art or by processes analogous to those described herein, using an appropriate isotopically-labeled reagent in place of the non-labeled reagent otherwise employed. Such compounds have a variety of potential uses, e.g., as standards and reagents in determining the ability of a potential

pharmaceutical compound to bind to target proteins or receptors, or for imaging compounds of this invention bound to biological receptors in vivo or in vitro.

[00182] "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(0)₂H, or S(0)H group.

[00183] 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. The solvent molecules in the solvate may be present in a regular arrangement and/or a non-ordered arrangement. The solvate may comprise either a stoichiometric or nonstoichiometric amount of the solvent molecules. "Solvate" encompasses both solution-phase and isolable solvates. Exemplary solvates include, but are not limited to, hydrates, ethanolates, methanolates, and isopropanolates. Methods of solvation are generally known in the art.

[00185] The compounds of the present invention can be prepared in a number of ways known to one skilled in the art of organic synthesis. IV. BIOLOGY [00186] 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 thromboembolic disorders and include acute coronary syndrome, unstable angina, myocardial infarction, thrombosis in the cavity of the heart, 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, stents, artificial heart valves, and hemodialysis membranes.

[00187] Some conditions contribute to the risk of developing thrombosis. For example, alterations of the vessel wall, changes in the flow of blood, and alterations in the composition of the vascular compartment. These risk factors are collectively known as Virchow's triad. (Colman, R.W. et al., eds., Hemostasis and Thrombosis, Basic Principles and Clinical Practice, 5th Edition, p. 853, Lippincott Williams & Wilkins (2006))

[00188] Antithrombotic agents are frequently given to patients at risk of developing thromboembolic disease because of the presence of one or more predisposing risk factors from Virchow's triad to prevent formation of an occlusive thrombus (primary prevention). For example, in an orthopedic surgery setting {e.g. , hip and knee replacement), an antithrombotic agent is frequently administered prior to a surgical procedure. The antithrombotic agent counterbalances the prothrombotic stimulus exerted by vascular flow alterations (stasis), potential surgical vessel wall injury, as well as changes in the composition of the blood due to the acute phase response related to surgery. Another example of the use of an antithrombotic agent for primary prevention is dosing with aspirin, a platelet activation inhibitor, in patients at risk for developing thrombotic cardiovascular disease. Well recognized risk factors in this setting include age, male gender, hypertension, diabetes mellitus, lipid alterations, and obesity.

[00189] Antithrombotic agents are also indicated for secondary prevention, following an initial thrombotic episode. For example, patients with mutations in factor V (also known as factor V Leiden) and additional risk factors {e.g., pregnancy), are dosed with anticoagulants to prevent the reoccurrence of venous thrombosis. Another example entails secondary prevention of cardiovascular events in patients with a history of acute myocardial infarction or acute coronary syndrome. In a clinical setting, a combination of aspirin and clopidogrel (or other thienopyridines) may be used to prevent a second thrombotic event.

[00190] Antithrombotic agents are also given to treat the disease state (i.e., by arresting its development) after it has already started. For example, patients presenting with deep vein thrombosis are treated with anticoagulants (i.e., heparin, warfarin, or LMWH) to prevent further growth of the venous occlusion. Over time, these agents also cause a regression of the disease state because the balance between prothrombotic factors and anticoagulant/pro fibrinolytic pathways is changed in favor of the latter. Examples on the arterial vascular bed include the treatment of patients with acute myocardial infarction or acute coronary syndrome with aspirin and clopidogrel to prevent further growth of vascular occlusions and eventually leading to a regression of thrombotic occlusions.

[00191] Thus, antithrombotic agents are used widely for primary and secondary prevention (i.e., prophylaxis or risk reduction) of thromboembolic disorders, as well as treatment of an already existing thrombotic process. 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)).

[00192] An alternative way of initiation of coagulation is operative when blood is exposed to artificial surfaces (e.g., during hemodialysis, "on-pump" cardiovascular surgery, vessel grafts, bacterial sepsis), on cell surfaces, cellular receptors, cell debris, DNA, RNA, and extracellular matrices. This process is also termed contact activation. Surface absorption of factor XII leads to a conformational change in the factor XII molecule, thereby facilitating activation to proteolytic active factor XII molecules (factor Xlla and factor Xllf). Factor Xlla (or Xllf) has a number of target proteins, including plasma prekallikrein and factor XI. Active plasma kallikrein further activates factor XII, leading to an amplification of contact activation. Alternatively, the serine protease prolylcarboxylpeptidase can activate plasma kallikrein complexed with high molecular weight kininogen in a multiprotein complex formed on the surface of cells and matrices (Shariat-Madar et al, Blood, 108 : 192- 199 (2006)). Contact activation is a surface mediated process responsible in part for the regulation of thrombosis and inflammation, and is mediated, at least in part, by fibrinolytic-, complement-, kininogen/kinin-, and other humoral and cellular pathways (for review, Coleman, R., "Contact Activation Pathway", Hemostasis and Thrombosis, pp. 103-122, Lippincott Williams & Wilkins (2001); Schmaier, A.H., "Contact Activation", Thrombosis and Hemorrhage, pp. 105-128 (1998)). The biological relevance of the contact activation system for thromboembolic diseases is supported by the phenotype of factor XII deficient mice. More specifically, factor XII deficient mice were protected from thrombotic vascular occlusion in several thrombosis models as well as stroke models and the phenotype of the XII deficient mice was identical to XI deficient mice (Renne et al, J. Exp. Med., 202:271-281 (2005);

Kleinschmitz et al., J. Exp. Med., 203:513-518 (2006)). The fact that factor XI is down- stream from factor Xlla, combined with the identical phenotype of the XII and XI deficient mice suggest that the contact activation system could play a major role in factor XI activation in vivo.

[00193] Factor XI is a zymogen of a trypsin-like serine protease and is present in plasma at a relatively low concentration. Proteolytic activation at an internal R369-1370 bond yields a heavy chain (369 amino acids) and a light chain (238 amino acids). The latter contains a typical trypsin-like catalytic triad (H413, D464, and S557). Activation of factor XI by thrombin is believed to occur on negatively charged surfaces, most likely on the surface of activated platelets. Platelets contain high affinity (0.8 nM) specific sites (130-500/platelet) for activated factor XI. After activation, factor XIa remains surface bound and recognizes factor IX as its normal macromolecular substrate. (Galiani, D., Trends Cardiovasc. Med, 10: 198-204 (2000))

[00194] In addition to the feedback activation mechanisms described above, thrombin activates thrombin activated fibrinolysis inhibitor (TAFI), a plasma carboxypeptidase that cleaves C-terminal lysine and arginine residues on fibrin, reducing the ability of fibrin to enhance tissue-type plasminogen activator (tPA) dependent plasminogen activation. In the presence of antibodies to FXIa, clot lysis can occur more rapidly independent of plasma TAFI concentration. (Bouma, B.N. et al., Thromb. Res., 101 :329-354 (2001).) Thus, inhibitors of factor XIa are expected to be anticoagulant and pro fibrinolytic.

[00195] Further evidence for the anti-thromboembolic effects of targeting factor XI is derived from mice deficient in factor XI. It has been demonstrated that complete fXI deficiency protected mice from ferric chloride (FeC^-induced carotid artery thrombosis (Rosen et al, Thromb. Haemost., 87:774-777 (2002); Wang et al, J. Thromb. Haemost., 3:695-702 (2005)). Also, factor XI deficiency rescues the perinatal lethal phenotype of complete protein C deficiency (Chan et al, Amer. J. Pathology, 158:469-479 (2001)). Furthermore, baboon cross-reactive, function blocking antibodies to human factor XI protect against baboon arterial - venous shunt thrombosis (Gruber et al, Blood, 102:953- 955 (2003)). Evidence for an antithrombotic effect of small molecule inhibitors of factor Xla is also disclosed in published U.S. Patent Application No. 2004/0180855 Al . Taken together, these studies suggest that targeting factor XI will reduce the propensity for thrombotic and thromboembolic diseases.

[00196] Genetic evidence indicates that factor XI is not required for normal homeostasis, implying a superior safety profile of the factor XI mechanism compared to competing antithrombotic mechanisms. In contrast to hemophilia A (factor VIII deficiency) or hemophilia B (factor IX deficiency), mutations of the factor XI gene causing factor XI deficiency (hemophilia C) result in only a mild to moderate bleeding diathesis characterized primarily by postoperative or posttraumatic, but rarely

spontaneous hemorrhage. Postoperative bleeding occurs mostly in tissue with high concentrations of endogenous fibrinolytic activity (e.g., oral cavity, and urogenital system). The majority of the cases are fortuitously identified by preoperative

prolongation of aPTT (intrinsic system) without any prior bleeding history.

[00197] The increased safety of inhibition of Xla as an anticoagulation therapy is further supported by the fact that Factor XI knock-out mice, which have no detectable factor XI protein, undergo normal development, and have a normal life span. No evidence for spontaneous bleeding has been noted. The aPTT (intrinsic system) is prolonged in a gene dose-dependent fashion. Interestingly, even after severe stimulation of the coagulation system (tail transection), the bleeding time is not significantly prolonged compared to wild-type and heterozygous litter mates. (Gailani, D., Frontiers in Bioscience, 6:201-207 (2001); Gailani, D. et al, Blood Coagulation and Fibrinolysis, 8: 134-144 (1997).) Taken together, these observations suggest that high levels of inhibition of factor Xla should be well tolerated. This is in contrast to gene targeting experiments with other coagulation factors, excluding factor XII.

[00198] In vivo activation of factor XI can be determined by complex formation with either CI inhibitor or alpha 1 antitrypsin. In a study of 50 patients with acute myocardial infarction (AMI), approximately 25% of the patients had values above the upper normal range of the complex ELISA. This study can be viewed as evidence that at least in a subpopulation of patients with AMI, factor XI activation contributes to thrombin formation (Minnema, M.C. et al., Arterioscler. Thromb. Vase. Biol., 20:2489-2493 (2000)). A second study establishes a positive correlation between the extent of coronary arteriosclerosis and factor XIa in complex with alpha 1 antitrypsin (Murakami, T. et al., Arterioscler. Thromb. Vase. Biol, 15: 1107-1113 (1995)). In another study, Factor XI levels above the 90th percentile in patients were associated with a 2.2-fold increased risk for venous thrombosis (Meijers, J.C.M. et al, N. Engl. J. Med., 342:696-701 (2000)).

[00199] Plasma kallikrein is a zymogen of a trypsin- like serine protease and is present in plasma at 35 to 50 μg/mL. The gene structure is similar to that of factor XI. Overall, the amino acid sequence of plasma kallikrein has 58% homology to factor XI. Proteolytic activation by factor Xlla at an internal I 389- R390 bond yields a heavy chain (371 amino acids) and a light chain (248 amino acids). The active site of plasma kallikrein is contained in the light chain. The light chain of plasma kallikrein reacts with protease inhibitors, including alpha 2 macroglobulin and CI - inhibitor. Interestingly, heparin significantly accelerates the inhibition of plasma kallikrein by antithrombin III in the presence of high molecular weight kininogen (HMWK). In blood, the majority of plasma kallikrein circulates in complex with HMWK. Plasma kallikrein cleaves HMWK to liberate bradykinin. Bradykinin release results in increase of vascular permeability and vasodilation (for review, Coleman, R., "Contact Activation Pathway", Hemostasis and Thrombosis, pp. 103-122, Lippincott Williams & Wilkins (2001); Schmaier A.H., "Contact Activation", Thrombosis and Hemorrhage, pp. 105-128 (1998)).

[00200] Also, it is preferred to find new compounds with improved activity in in vitro clotting assays, compared with known serine protease inhibitors, such as the activated partial thromboplastin time (aPTT) or prothrombin time (PT) assay, (for a description of the aPTT and PT assays see, Goodnight, S.H. et al, "Screening Tests of Hemostasis", Disorders of Thrombosis and Hemostasis: A Clinical Guide, 2nd Edition, pp. 41-51, McGraw-Hill, New York (2001)).

[00201] It is also desirable and preferable to find compounds with advantageous and improved characteristics compared with known serine protease inhibitors, 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 concentration peak-to-trough characteristics; (e) factors that increase the concentration of active drug at the enzyme; (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.

[00202] Pre-clinical studies demonstrated significant antithrombotic effects of small molecule factor XIa inhibitors in rabbit and rat model of arterial thrombosis, at doses that preserved hemostasis. (Wong P.C. et al., American Heart Association Scientific Sessions, Abstract No. 6118, November 12-15, 2006; Schumacher, W. et al, Journal of

Thrombosis and Haemostasis, 3(Suppl. 1):P1228 (2005); Schumacher, W.A. et al, European Journal of Pharmacology, pp. 167-174 (2007)). Furthermore, it was observed that in vitro prolongation of the aPTT by specific XIa inhibitors is a good predictor of efficacy in our thrombosis models. Thus, the in vitro aPTT test can be used as a surrogate for efficacy in vivo.

[00203] As used herein, the term "patient" encompasses all mammalian species.

[00204] 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.

The term "thromboembolic disorders" entails both "thrombotic" and "embolic" disorders (defined above).

[00209] The term "thromboembolic disorders" as used herein includes arterial cardiovascular thromboembolic disorders, venous cardiovascular or cerebrovascular thromboembolic disorders, and thromboembolic disorders in the chambers of the heart or in the peripheral circulation. 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 arterial thrombosis, cerebral arterial thrombosis, cerebral embolism, kidney embolism, pulmonary embolism, 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, ventricular assist devices and artificial hearts or heart chambers, and vessel grafts. The procedures include, but are not limited to:

cardiopulmonary bypass, percutaneous coronary intervention, and hemodialysis. In another embodiment, the term "thromboembolic disorders" includes acute coronary syndrome, stroke, deep vein thrombosis, and pulmonary embolism. [00210] In another embodiment, the present invention provides a method for the treatment of a thromboembolic disorder, wherein the thromboembolic disorder is selected from unstable angina, an acute coronary syndrome, atrial fibrillation, myocardial infarction, transient ischemic attack, stroke, atherosclerosis, peripheral occlusive arterial disease, venous thrombosis, deep vein thrombosis, thrombophlebitis, arterial embolism, coronary arterial thrombosis, cerebral arterial thrombosis, cerebral embolism, kidney embolism, pulmonary embolism, and thrombosis resulting from medical implants, devices, or procedures in which blood is exposed to an artificial surface that promotes thrombosis.

In another embodiment, the present invention provides a method for the primary prophylaxis of a thromboembolic disorder, wherein the thromboembolic disorder is selected from acute coronary syndrome, stroke, venous thrombosis, and thrombosis resulting from medical implants and devices.

[00212] In another embodiment, the present invention provides a method for the secondary prophylaxis of a thromboembolic disorder, wherein the thromboembolic disorder is selected from unstable angina, an acute coronary syndrome, atrial fibrillation, recurrent myocardial infarction, transient ischemic attack, stroke, atherosclerosis, peripheral occlusive arterial disease, venous thrombosis, deep vein thrombosis, thrombophlebitis, arterial embolism, coronary arterial thrombosis, cerebral arterial thrombosis, cerebral embolism, kidney embolism, pulmonary embolism, and thrombosis resulting from medical implants, devices, or procedures in which blood is exposed to an artificial surface that promotes thrombosis. In another embodiment, the present invention provides a method for the secondary prophylaxis of a thromboembolic disorder, wherein the thromboembolic disorder is selected from acute coronary syndrome, stroke, atrial fibrillation and venous thrombosis.

[00213] 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.

[00214] 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.

[00215] Thromboembolic disorders are frequently associated with patients with atherosclerosis. Risk factors for atherosclerosis include but are not limited to male gender, age, hypertension, lipid disorders, and diabetes mellitus. Risk factors for atherosclerosis are at the same time risk factors for complications of atherosclerosis, i.e., thromboembolic disorders.

[00216] Similarly, arterial fibrillation is frequently associated with thromboembolic disorders. Risk factors for arterial fibrillation and subsequent thromboembolic disorders include cardiovascular disease, rheumatic heart disease, nonrheumatic mitral valve disease, hypertensive cardiovascular disease, chronic lung disease, and a variety of miscellaneous cardiac abnormalities as well as thyrotoxicosis.

[00217] Diabetes mellitus is frequently associated with atherosclerosis and

thromboembolic disorders. Risk factors for the more common type 2 include but are not limited to are family history, obesity, physical inactivity, race / ethnicity, previously impaired fasting glucose or glucose tolerance test, history of gestational diabetes mellitus or delivery of a "big baby", hypertension, low HDL cholesterol, and polycystic ovary syndrome.

[00218] Risk factors for congenital thrombophilia include gain of function mutations in coagulation factors or loss of function mutations in the anticoagulant- or fibrinolytic pathways. [00219] Thrombosis has been associated with a variety of tumor types, e.g., pancreatic cancer, breast cancer, brain tumors, lung cancer, ovarian cancer, prostate cancer, gastrointestinal malignancies, and Hodgkins or non-Hodgkins lymphoma. Recent studies suggest that the frequency of cancer in patients with thrombosis reflects the frequency of a particular cancer type in the general population (Levitan, N. et al., Medicine

(Baltimore), 78(5):285-291 (1999); Levine M. et al, N. Engl. J. Med., 334(1 1):677-681 (1996); Blom, J.W. et al, JAMA, 293(6):715-722 (2005)). Hence, the most common cancers associated with thrombosis in men are prostate, colorectal, brain, and lung cancer, and in women are breast, ovary, and lung cancer. The observed rate of venous thromboembolism (VTE) in cancer patients is significant. The varying rates of VTE between different tumor types are most likely related to the selection of the patient population. Cancer patients at risk for thrombosis may possess any or all of the following risk factors: (i) the stage of the cancer {i.e., presence of metastases), (ii) the presence of central vein catheters, (iii) surgery and anticancer therapies including chemotherapy, and (iv) hormones and antiangiogenic drugs. Thus, it is common clinical practice to dose patients having advanced tumors with heparin or low molecular heparin to prevent thromboembolic disorders. A number of low molecular heparin preparations have been approved by the FDA for these indications.

[00220] There are three main clinical situations when considering the prevention of VTE in a medical cancer patient: (i) the patient is bedridden for prolonged periods of time; (ii) the ambulatory patient is receiving chemotherapy or radiation; and (iii) the patient is with indwelling central vein catheters. Unfractionated heparin (UFH) and low molecular weight heparin (LMWH) are effective antithrombotic agents in cancer patients undergoing surgery. (Mismetti, P. et al, British Journal of Surgery, 88:913-930 (2001).)

A. In Vitro Assays

[00221] The effectiveness of compounds of the present invention as inhibitors of the coagulation Factors XIa, Vila, IXa, Xa, Xlla, 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 or fluorogenic substrate by the relevant serine protease was measured both in the absence and presence of

compounds of the present invention. Assays were conducted at room temperature or at 37 °C. 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.

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.

[00225] 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.

[00226] Factor Xlla determinations were made in 50 mM HEPES buffer at pH 7.4 containing 145 mM NaCl, 5 mM KC1, and 0.1% PEG 8000. Determinations were made using purified human Factor Xlla at a final concentration of 4 nM (American

Diagnostica) and the synthetic substrate SPECTROZYME® #312 (H-D-CHT-Gly-L-Arg- pNA.2AcOH; American Diagnostica) at a concentration of 0.00015 M.

[00227] Plasma kallikrein determinations were made in 0.1 M sodium phosphate buffer at a pH of 7.5 containing 0.1-0.2 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.

[00228] 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. Determinations were made using purified human alpha thrombin (Haemato logic 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® or AnaSpec) at a concentration of 0.0002-0.0004 M.

[00229] The Michaelis constant, K_m, for substrate hydrolysis by each protease, was determined at 25 °C or 37 °C. Values of K; 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 K; values:

(v₀-v_s)/v_s = I/(Ki(l + S/K_m)) for a competitive inhibitor with one binding site; or v_s/v₀ = A + ((B-A)/(l + ((IC₅₀/(I))ⁿ))); and

Ki = IC₅₀/(1 + S/K_m) for a competitive inhibitor,

where:

v₀ 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. [00230] The selectivity of a compound may be evaluated by taking the ratio of the Ki value for a given protease with the Ki value for the protease of interest (i.e., selectivity for FXIa versus protease P = Ki for protease P/ Ki for FXIa). Compounds with selectivity ratios >20 are considered selective. Compounds with selectivity ratios >100 are preferred, and compounds with selectivity ratios > 500 are more preferred.

[00231] 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.

[00232] 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.

[00233] 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.

[00234] Prothrombin Time (PT) is determined using thromboplastin (Thromboplastin C Plus or INNOVIN®, 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.

[00235] The exemplified Examples disclosed below were tested in the Factor XIa assay described above and found having Factor XIa inhibitory activity. A range of Factor XIa inhibitory activity (Ki values) of≤ 10 μΜ (10000 nM) was observed. Table 1 below lists Factor XIa Ki values measured for the following examples.

B. In Vivo Assays

[00236] 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 Arteriovenous Shunt Thrombosis Models. a. In Vivo Electrically-induced Carotid Artery Thrombosis (ECAT) Model

[00237] 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 niA 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 [00238] 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 ID₅₀ 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).

[00239] The anti-inflammatory effect of these compounds can be demonstrated in an Evans Blue dye extravasation assay using CI -esterase inhibitor deficient mice. In this model, mice are dosed with a compound of the present invention, Evans Blue dye is injected via the tail vein, and extravasation of the blue dye is determined by

spectrophotometric means from tissue extracts.

[00240] The ability of the compounds of the current invention to reduce or prevent the systemic inflammatory response syndrome, for example, as observed during on-pump cardiovascular procedures, can be tested in in vitro perfusion systems, or by on-pump surgical procedures in larger mammals, including dogs and baboons. Read-outs to assess the benefit of the compounds of the present invention include for example reduced platelet loss, reduced platelet / white blood cell complexes, reduced neutrophil elastase levels in plasma, reduced activation of complement factors, and reduced activation and/or consumption of contact activation proteins (plasma kallikrein, factor XII, factor XI, high molecular weight kininogen, CI -esterase inhibitors). [00241] The compounds of the present invention may also be useful as inhibitors of additional serine proteases, notably human thrombin, human plasma kallikrein and human plasmin. Because of their inhibitory action, these compounds are indicated for use in the prevention or treatment of physiological reactions, including blood coagulation, fibrinolysis, blood pressure regulation and inflammation, and wound healing catalyzed by the aforesaid class of enzymes. Specifically, the compounds have utility as drugs for the treatment of diseases arising from elevated thrombin activity of the aforementioned serine proteases, such as myocardial infarction, and as reagents used as anticoagulants in the processing of blood to plasma for diagnostic and other commercial purposes.

V. PHARMACEUTICAL COMPOSITIONS, FORMULATIONS AND

COMBINATIONS

[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 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, 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 Edition (1990).

[00244] 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.

[00245] 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 about 1000 mg/kg of body weight, preferably between about 0.01 to about 100 mg/kg of body weight per day, and most preferably between about 0.1 to about 20 mg/kg/day. Intravenously, the most preferred doses will range from about 0.001 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.

[00246] Compounds of this invention can also be administered by parenteral administration {e.g., intra- venous, intra-arterial, intramuscularly, or subcutaneously. When administered intra-venous or intra-arterial, the dose can be given continuously or intermittent. Furthermore, formulation can be developed for intramuscularly and subcutaneous delivery that ensure a gradual release of the active pharmaceutical ingredient. [00247] 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.

[00248] 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.

[00249] 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 cellulose, 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.

[00250] 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.

[00251] 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.

[00252] 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.

[00253] 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.

[00254] Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance.

[00255] 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.

[00256] Suitable pharmaceutical carriers are described in Remington 's Pharmaceutical Sciences, Mack Publishing Company, a standard reference text in this field. [00257] Where the compounds of this invention are combined with other anticoagulant agents, for example, a daily dosage may be about 0.1 to about 100 milligrams of the compound of the present invention and about 0.1 to about 100 milligrams 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 about 100 milligrams per dosage unit, and the second anti-coagulant in an amount of about 1 to about 50 milligrams per dosage unit.

[00258] 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 about 25 milligrams of the compound of the present invention and about 50 to about 150 milligrams of the anti-platelet agent, preferably about 0.1 to about 1 milligrams of the compound of the present invention and about 1 to about 3 milligrams of anti-platelet agents, per kilogram of patient body weight.

[00259] Where the compounds of the present invention are administered in

combination with thrombolytic agent, typically a daily dosage may be about 0.1 to about 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.

[00260] 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.

[00261] 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.

[00267] In another embodiment, the present invention provides a pharmaceutical composition, wherein the additional therapeutic agent is the anti-platelet agent clopidogrel.

[00268] The compounds of the present invention can be administered alone or in combination with one or more additional therapeutic agents. 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.

[00269] Compounds that can be administered in combination with the compounds of the present invention include, but are not limited to, anticoagulants, anti-thrombin agents, anti-platelet agents, fibrinolytics, hypolipidemic agents, antihypertensive agents, and anti- ischemic agents.

[00270] Other anticoagulant agents (or coagulation inhibitory agents) that may be used in combination with the compounds of this invention include warfarin, heparin (either unfractionated heparin or any commercially available low molecular weight heparin, for example LOVENOX®), synthetic Pentasaccharide, direct acting thrombin inhibitors including hirudin and argatroban, as well as other factor Vila inhibitors, factor IXa inhibitors, factor Xa inhibitors (e.g. , ARIXTRA® , apixaban, rivaroxaban, LY-517717, DU-176b, DX-9065a, and those disclosed in WO 98/57951 , WO 03/026652, WO

01/047919, and WO 00/076970), factor XIa inhibitors, and inhibitors of activated TAFI and PAI-1 known in the art.

[00271] The term anti-platelet agents (or platelet inhibitory agents), as used herein, denotes agents that inhibit platelet function, for example, by inhibiting the aggregation, adhesion or granule-content secretion of platelets. Such agents include, but are not limited to, the various known non-steroidal anti-inflammatory drugs (NSAIDs) such as acetaminophen, aspirin, codeine, diclofenac, droxicam, fentaynl, ibuprofen,

indomethacin, ketorolac, mefenamate, morphine, naproxen, phenacetin, piroxicam, sufentanyl, sulfinpyrazone, sulindac, and pharmaceutically acceptable salts or prodrugs thereof. Of the NSAIDs, aspirin (acetylsalicylic acid or ASA) and piroxicam are preferred. Other suitable platelet inhibitory agents include glycoprotein Ilb/IIIa antagonists (e.g., tirofiban, eptifibatide, abciximab, and integrelin), thromboxane-A2- receptor antagonists (e.g., ifetroban), thromboxane- A-synthetase inhibitors,

Preferred P2Yi₂ receptor antagonists include clopidogrel, ticlopidine, prasugrel, ticagrelor, and cangrelor, and

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

[00273] A preferred example is a triple combination of a compound of the present invention, aspirin, and another anti-platelet agent. Preferably, the anti-platelet agent is clopidogrel or prasugrel, more preferably clopidogrel.

[00274] 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 serotonin) and/or fibrin formation are disrupted. A number of thrombin inhibitors are known to one of skill in the art and these inhibitors are contemplated to be used in combination with the present compounds. Such inhibitors include, but are not limited to, boroarginine derivatives, boropeptides, heparins, hirudin, argatroban, dabigatran, AZD-0837, and those disclosed in WO 98/37075 and WO 02/044145, and pharmaceutically acceptable salts and prodrugs thereof.

[00277] 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 thrombin, Factor Vila, IXa, Xa, XIa, and/or plasma kallikrein. Such compounds may be provided in a commercial kit, for example, for use in

pharmaceutical research involving thrombin, Factor Vila, IXa, Xa, XIa, and/or plasma kallikrein. 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.

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 XIa was present.

[00279] Extremely potent and selective compounds of the present invention, those having K; values less than or equal to 0.001 μΜ against the target protease and greater than or equal to 0.1 μΜ against the other proteases, may also be used in diagnostic assays involving the quantitation of thrombin, Factor Vila, IXa, Xa, XIa, and/or plasma kallikrein in serum samples. For example, the amount of Factor XIa in serum samples could be determined by careful titration of protease activity in the presence of the relevant chromogenic substrate, S2366, with a potent and selective Factor XIa inhibitor of the present invention.

[00284] Other features of the invention will become apparent in the course of the following descriptions of exemplary embodiments that are given for illustration of the invention and are not intended to be limiting thereof. The following Examples have been prepared, isolated and characterized using the methods disclosed herein. VI. GENERAL SYNTHESIS INCLUDING SCHEMES

[00285] The compounds of the present invention may be synthesized by many methods available to those skilled in the art of organic chemistry (Maffrand, J.P. et al.,

Heterocycles, 16(l):35-37 (1981)). General synthetic schemes for preparing compounds of the present invention are described below. These schemes are illustrative and are not meant to limit the possible techniques one skilled in the art may use to prepare the compounds disclosed herein. Different methods to prepare the compounds of the present invention will be evident to those skilled in the art. Additionally, the various steps in the synthesis may be performed in an alternate sequence in order to give the desired compound or compounds.

[00286] Examples of compounds of the present invention prepared by methods described in the general schemes are given in the intermediates and examples section set out hereinafter. Example compounds are typically prepared as racemic mixtures.

Preparation of homochiral examples may be carried out by techniques known to one skilled in the art. For example, homochiral compounds may be prepared by separation of racemic products by chiral phase preparative HPLC. Alternatively, the example compounds may be prepared by methods known to give enantiomerically enriched products. These include, but are not limited to, the incorporation of chiral auxiliary functionalities into racemic intermediates which serve to control the diastereoselectivity of transformations, providing enantio-enriched products upon cleavage of the chiral auxiliary.

[00287] 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.

[00288] 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, 4th Edition, Wiley- Interscience (2006)).

[00289] Certain 2-bromoacetophenone analogs (lb) that are not commercially available but used in the current invention may be synthesized from commercially available starting materials as described in Scheme 1. Acetophenone derivatives la can be treated with a brominating reagent such as bromine in a solvent such as CHCI₃ to give lb. Alternatively, acetophenone derivatives la can be treated with either copper (II) bromide in a solvent such as EtOAc at elevated temperature or

phenyltrimethylammonium tribromide in a solvent such as THF at low temperature to provide lb. Benzoic acid derivatives lc can be treated sequentially with oxalyl chloride in a suitable solvent, such as DCM, containing a few drops of DMF, and then treated with trimethylsilyldiazomethane in a suitable solvent or solvent combination, such as ACN and hexane. The intermediate diazoketone is isolated and treated with aqueous hydrobromic acid and DCM to provide lb. Alternatively the benzoic acid derivatives lc can be converted to the acetophenone derivatives la in three steps as described in Scheme 1. Alternatively, Stille coupling between a suitably substituted aryl halide or triflate and tributyl-(l-ethoxyvinyl) stannane with a palladium catalyst, such as bis- (triphenylphosphine)palladium dichloride, in a suitable solvent, such as toluene, at elevated temperature yields the enol ether le, which can then be converted to lb with N- bromosuccinimide.

[00290] Triazole acids of this invention such as 2c, 2d, 2e, 2f can be easily prepared from readily accessible anilines in a three step process outlined in Scheme 2. Formation of the arylazide (2b) intermediate via diazotization and displacement with sodium azide followed by condensation with appropriate acetylenic compounds and removal of the protecting groups known to those in the art should afford intermediates such as 2c.

Condensation of the arylazides with either malonates or ketoesters followed by hydrolysis should afford intermediates of this invention such as 2d, 2e and 2f. In cases wherein the anilines are not available, the corresponding arylcarboxylic acids can be used which are then converted to the anilines via the Curtius rearrangement. Alternatively haloaryl intermediates can be lithiated via BuLi and reacted with C0₂ to afford the corresponding carboxylic acids which can then be converted to the anilines as outlined below.

Scheme 2

[00291] Substituted hydrazine (3 a) of this invention can be obtained from commercial sources or can be made from the corresponding anilines via diazotization followed by reduction with tin chloride. These can be reacted either directly or after isolation with an appropriate malononitrile to afford aminopyrazole such as compound 3b. Treatment of 3b with isoamylnitrite in THF under elevated temperatures should provide the requisite pyrazole intermediate which is hydrolyzed to afford pyrazole acid intermediates of this invention such as 3c. Furthermore amino pyrazole intermediates of this invention can be obtained by hydrolysis of the ester will give 3d. Diazotization of the amino moiety as in 3b in fluoroboric acid followed by heating at high temperature should then provide fluoropyrazole intermediates such as 3e. Appropriately substituted hydrazines can be condensed with (E)-ethyl 2-((dimethylamino)methylene)-3-oxobutanoate to give, after hydrolysis, the methyl pyrazole derivatives 3f.

Scheme 3

[00292] Alternative approaches to pyrazoles can also be obtained via the Chan-Lam coupling as shown in Scheme 4. The requisite pyrazole (4b) and appropriately substituted boronic acids (4a) are commercially available. Alternatively these entities could be coupled via the Ullman coupling methodology with Cul, K₂CO₃ in DMSO at 130 °C. In these cases the boronic acid derivatives would be substituted with the arylbromides or iodides.

[00293] Imidazole acids of this invention such as 4af and 4ag can be prepared as outlined in Scheme 4a. Ullman coupling between an appropriately substituted imidazole 4aa and an appropriately substituted arylhalide 4ab can provide the imidazole derivatives 4ad and 4ae in one step. Hydrolysis of the ester will generate the imidazole acids 4af and 4ag. Alternatively, an appropriately substituted imidazole 4aa can be coupled to an appropriately substituted arylboronic acid 4ac using a modified procedure described by Sreedhar {Synthesis, 5:795 (2008)). Alternative approaches to the imidazole derivatives 4ad and 4ae can be achieved using a modified procedure described by Gomez-Sanchez (J. Heterocyclic Chem., 24: 1757 (1987)). Condensation of the ethyl nitroacetate, triethyl orthoformate, and an appropriately substituted aniline (4ah) can provide ethyl 3- arylamino-2-nitroacrylate 4ai. The ethyl 3-arylamino-2-nitrocrotonate derivatives 4aj can be prepared by reacting ethyl 3-ethoxy-2-nitrocrotonate with an appropriately substituted aniline 4ah. Reacting compounds 4ai and 4aj with triethyl orthoformate and platinum on carbon under a hydrogen atmosphere at elevated temperature can yield the imidazole derivatives 4ad and 4ae. Hydrolysis of the ester will generate the imidazole acids 4af and 4ag. Scheme 4a

[00294] Bicyclic pyrazole intermediates of this invention can be constructed via the methodology outline in Scheme 5. Reaction of the hydrazine (3a) with an appropriate aldehyde should afford the hydrazone 5a which on chlorination with NCS followed by condensation with an appropriate malonate should lead to pyrazole such as 5b. Coupling of the requisite acid with macrocyclic amines of this invention should lead to

carboxamide pyrazole 5 c which can be converted to the compounds of this invention via methods outlined or known to those in the art. Scheme 5 e

[00295] Intermediates for preparation of compounds of this invention wherein ring B is an imidazole ring, can be prepared from an appropriately N-protected allylglycine (6a) according to the general method outlined in Scheme 6 (Contour-Galcera et al., Bioorg. Med. Chem. Lett., 11(5):741-745 (2001)). Condensation of 6a with a suitably substituted bromoacetophenone (lb) in the presence of a suitable base such as potassium bicarbonate, K₂C0₃ or Cs₂C0₃ in a suitable solvent such as DMF provides a keto ester intermediate which can be cyclized to afford an imidazole (6c) by heating in the presence of excess ammonium acetate in a solvent such as toluene or xylene. This latter transformation can be conveniently carried out on small scale at 160 °C in a microwave reactor or on larger scale by refluxing the mixture while removing water via a Dean-Stark trap. The resulting imidazole intermediate (6c) is then protected by treatment with SEM-C1 in the presence of a base such as sodium hydride or dicyclohexylmethylamine in a solvent such as THF or DCM. The aryl bromide (6d) is then converted to the corresponding aniline (6e) by heating in a sealed vessel with excess ammonium hydroxide, in the presence of copper iodide, a base such as Cs₂C0₃ and a catalytic amount of proline in DMSO as solvent. Acylation of 6e with the appropriate alkenoic acid and a coupling agent such as T3P or

BOP reagent, or alternately, by treatment with an alkenoic acid chloride in the presence of a base such as TEA or DIEA provides diene 6f, which undergoes ring closing metathesis by heating in dilute solution in the presence of /^-toluene sulfonic acid and Grubbs II catalyst in a suitable solvent such as DCM or DCE to provide the corresponding macrocycle (6g) {Tetrahedron Letters, 44: 1379 (2003)). Alternately, the RCM can be run in a microwave at elevated temperatures without /?TsOH. Chlorination on the imidazole ring with NCS, or initial reduction of the double bond followed by chlorination, and deprotection provides intermediates 6h and 6i, respectively. Alternately, for compounds wherein R₁₀ = CN, catalytic hydrogenation of 6g followed by bromination with NBS at room temperature and subsequent palladium-catalyzed cyanation and deprotection provides intermediate 6j. Intermediates 6h-j can be converted to compounds of this invention following the steps described in Scheme 15.

Scheme 6

[00296] Representative imidazole containing amide macrocycle intermediates useful for the synthesis of compounds of this invention are described in Scheme 7. The aniline 6e can be coupled with an appropriately substituted carboxylic acid 7a using propane phosphonic acid anhydride (T3P) to give the amide 7b (n=0) and 7c (n=l). Using a modified procedure described by Lovely {Tetrahedron Letters, 44: 1379 (2003)), 7b and 7c, following pretreatment with /?-TsOH to form the imidazolinium ion, can be cyclized via ring-closing metathesis using a catalyst, such as Grubbs (II), in a suitable solvent, such as DCM, DCE, or toluene at elevated temperature, to give the imidazole-containing macrocycles 7d (n=0) and 7e (n=l). The alkene can then be reduced with hydrogen over either palladium on carbon or platinum oxide and subsequent deprotection with TFA in DCM provides amine 7f and 7g. Compounds of the formulae 7f and 7g can be converted to compounds in this invention according to Scheme 15.

Scheme 7

[00297] Representative regioisomeric imidazole containing amide macrocycle intermediates useful for the synthesis of compounds of this invention are described in Scheme 7a. An appropriately N-protected allylglycine 6a can be converted to the bromoketone 7ab in two steps. Condensation of 7ab with formamidine at elevated temperature generates the imidazole 7ac. The imidazole 7ac can be protected with SEM- Cl and then deprotonation with nBuLi and subsequent quenching with NBS provides the bromo imidazole 7ae. Suzuki-Miyaura coupling between bromo imidazole 7ae and an appropriately substituted aryl or heteroaryl boronic acid or ester 1 le in the presence of a base such as K3PO4 using a precatalyst such as Pd(dppf)Cl₂*CH₂Cl₂ complex provides, after separation of the enantiomers, aniline 7af. Aniline 7af can be converted to 7ag and 7ah according to Scheme 7. Compounds of the formulae 7ag and 7ah can be converted to compounds in this invention according to Scheme 15.

Scheme 7a

7ah: n = 1

[00298] Alternatively, imidazole containing macrocycles of this invention can be derived from intermediate 8e according to Scheme 8. Ullmann type coupling reaction of compound 6d and allyl glycine, followed by methylation of the acid would provide the extended aniline analog 8b. Ring closing metathesis of the diene 8b using Grubb II catalyst would provide the macrocyclic olefin 8c. Then, the macrocyclic olefin 8c may be converted to the key intermediate 8e via hydrogenation and selective deprotection of the amine protecting group from compound 8d. The amine 8e may be converted to the corresponding cyclic carbamate or other analogs following the procedures described in Scheme 15. The other diastereomer at the methyl ester position can also be made same way as described above.

Scheme 8

8c 8d 8e

[00299] The cyano or chloro imidazole analog of intermediate 8e may be obtained by a slightly modified sequence of Scheme 9. The aniline nitrogen in compound 8b may be protected with a trifluoroacetyl group (TFA) in order to suppress

bromination/chlorination on the phenyl group during conversion of compound 9b to 9c. Following the same sequence as outlined in Scheme 8, the resulting protected aniline 9a may be converted to macrocyclic compound 9b. Bromination or chlorination of 9b with NBS or NCS respectively provides intermediates 9c. For compounds wherein R¹⁰ is CN, bromide 9c is converted to cyanoimidazole 9d by palladium-catalyzed cyanation as described in Scheme 6 above. Selective removal of the amine protecting group from compound 9d provides amine intermediates 9e. For example a Boc protecting group can be selectively removed either under mild acidic conditions or thermally by heating in trifluoroethanol in a microwave at 150 °C. Intermediate 9e can be converted to the final compounds described in this invention according to Scheme 15.

[00300] Alternatively, imidazole compounds of this invention can be derived from trifluoromethyl substituted macrocycle intermediates, 10c which can be prepared from aniline 6e following the sequence described in Scheme 10. A condensation reaction of the aniline 6e with trifluoroacetaldehyde ethyl hemiacetal provides the aminal 10a. Treatment of 10a with allyl Grignard reagent, provides aniline 10b, which is then converted to the target compound 10c via the sequence described in Scheme 6.

)₂

[00301] Representative compounds of this invention where ring B is a six-membered heterocycle (example - pyridine) can be derived from intermediates 111, the synthesis of which is described in Scheme 11. Condensation of aldehyde 11a (X = N) prepared according to a modified procedure described by Negi {Synthesis, 991 (1996)), with (S)-2- methylpropane-2-sulfinamide in the presence of anhydrous copper sulfate in a solvent such as DCM gives the sulfmimine lib (Ellman, J., J. Org. Chem., 64:1278 (1999)). Using a modified procedure described by Kuduk {Tetrahedron Letters, 45:6641 (2004)), suitably substituted Grignard reagents, for example allylmagnesium bromide, can be added to sulfinimine lib to give a sulfinamide 11c, as a mixture of diastereomers which can be separated at various stages of the sequence. The diastereoselectivity for the addition of allymagnesium bromide to sulfinimine lib can be improved by employing indium(III) chloride according to a modified procedure of Xu (Xu, M-H, Organic Letters, 10(6): 1259 (2008)). Suzuki-Miyaura coupling between 4-chloropyridine lc and an appropriately substituted aryl or heteroaryl boronic acid or ester lie in the presence of a base such as potassium phosphate, in a solvent mixture, such as DMSO and H₂0, or DMF, using a precatalyst such as Pd(dppf)Cl₂*CH₂Cl₂ complex provides llg.

Alternatively, the Suzuki-Miyaura coupling between boronic acid lid and an

appropriately substituted aryl or heteroaryl halide llf can be used to prepared llg.

Protecting group interconversion can be accomplished in two steps to give llh.

Alternatively, the protecting group interconversion can take place initially on 11c

followed by the Suzuki-Miyaura coupling. The aniline llh can then be coupled with an appropriately substituted carboxylic acid Hi using T3P and a base, such as pyridine, to give the amide llj . Using a modified procedure described by Lovely {Tetrahedron Letters, 44: 1379 (2003)), llj, following pretreatment with / toluenesulfonic acid to form the pyridinium ion, can be cyclized via ring-closing metathesis using a catalyst, such as Grubbs (II), in a suitable solvent, such as DCM, DCE, or toluene at elevated temperature, to give the pyridine-containing macrocycle Ilk. The alkene can be reduced with hydrogen over either palladium on carbon or platinum oxide, and subsequent deprotection with TFA in DCM or 4M HC1 in dioxane provides amine 111. Compounds of the formulae 111 can be converted to compounds in this invention according to Scheme 15.

[00302] Additional pyridine containing macrocycles useful for the synthesis of compounds of this invention can also be prepared according to Scheme 1 1. In cases where the pyridine core is a 4-pyridine (Z = N) rather than the 2-pyridine (X = N), conversion of 1 lh to 1 lj can be easily accomplished by using an acid chloride of 1 li. Intermediates of formulae l lg where R⁸ = N0₂ may be modified further to give intermediates where R⁸ = NH C0₂-Ci_₄ alkyl either before coupling with acid 1 li or after coupling with acid. Reduction of the nitro group to an amino group may be accomplished with a reducing agent {e.g., Zn-NH₄C1) in an inert solvent {e.g., MeOH) to give an intermediate of formula 1 l g where R⁸ = NH₂. These anilino derivatives may be coupled with chloroalkanoates of the formula ClC0₂-Ci_₄ alkyl in the presence of a base {e.g., DIEA) in an inert solvent {e.g. , DCM) to give intermediates where R⁸ = NH C0₂-Ci_₄ alkyl. Scheme 12

[00303] The amino ester analog 13e was obtained from key intermediate 12j following the sequence described in Scheme 13. Step-wise imine formation of 12j with ethyl 2,3- dioxopropanoate followed by addition of allyltributyltin under tin (IV) chloride conditions afforded RCM precursor 13a. Following the same sequence in Scheme 12, 13a can be converted into critical intermediate 13e over several steps. Other macrocyclic intermediates such as 13e wherein the ester is replaced with a variety of substituents can also be similarly constructed and following the sequence of reactions outlined above can be converted to compounds of this invention according to Scheme 15.

Scheme 13

[00304] Methods for synthesis of a large variety of substituted pyridine compounds useful as starting materials for the preparation of compounds of the present invention are well known in the art and have been extensively reviewed. (For examples of methods useful for the preparation of pyridine starting materials see: Kroehnke, F., Synthesis, 1 (1976); Abramovitch, R.A., ed., "Pyridine and Its Derivatives", The Chemistry of

Heterocyclic Compounds, 14(Suppl. 1-4), John Wiley & Sons, New York (1974);

Boulton, A.J. et al., eds., Comprehensive Heterocyclic Chemistry, 2:165-524, Pergamon Press, New York (1984); McKillop, A., ed., Comprehensive Heterocyclic Chemistry, 5: 1- 300, Pergamon Press, New York (1996)).

[00305] In cases where suitably substituted boronic acids are not commercially available, a modification to this approach may be adopted wherein an aryl halide is subjected to a palladium mediated coupling with a diboron species such as bis(pinacolato) diboron or bis(neopentyl glycolato)diboron to provide the corresponding 4,4,5,5- tetramethyl-[l,3,2]dioxaborolane or the 5,5-dimethyl-[l,3,2]dioxaborolane intermediates using the method of Ishiyama, T. et al. (J. Org. Chem., 60(23):7508-7510 (1995)).

Alternately, this same intermediate can be prepared by reaction of the intermediate halide with the corresponding dialkoxyhydroborane as described by Murata et al. (J. Org.

Chem., 62(19):6458-6459 (1997)). The boron pinacolate intermediates can be used in place of boronic acids for coupling to the aryl/heteroaryl halides or triflates or the boron pinacolate intermediate can be converted to the boronic acids. Alternately, the corresponding boronic acids can be prepared by metal-halogen exchange of the aryl/heteroaryl halide, quenching with a trialkoxyborate reagent, and aqueous workup to provide the boronic acids (Miyaura, N. et al, Chem. Rev., 95:2457 (1995)).

[00306] It is also realized that the scope of intermediate synthesis can be further extended outside the use of Suzuki-Miyaura coupling methodology since the precursor aryl halides or triflates described above are also precursors for Stille, Negishi, Hiyama, and Kumada-type cross coupling methodologies (Tsuji, J., Transition Metal Reagents and Catalysts: Innovations in Organic Synthesis, John Wiley & Sons (2000); Tsuji, J., Palladium Reagents and Catalysts: Innovations in Organic Synthesis, John Wiley & Sons (1996)).

[00307] Additional pyridazine and pyridazinone containing macrocycles can be prepared according to Scheme 14. Condensation of the potassium salt of 14a with a suitably substituted a-ketoester 14b, which is either commercially available or prepared using a modified procedure described by Domagala {Tetrahedron Lett., 21 :4997-5000), in a solvent such as THF generates the α,β-unsaturated ketone derivative which can then be condensed with a suitably substituted hydrazine derivative to give pyridazinone 14c. The nitro group can then be reduced to the aniline 14f with zinc and NH₄C1 in methanol. The pyridazinone 14c can be converted to chloro-pyridazine 14d by deprotection of the amine protecting group, followed by treatment with POCI₃, then reprotection. The nitro group can be reduced to the aniline 14e with iron and AcOH. The anilines 14e and 14f can then be coupled with an appropriately substituted carboxylic acid 7a using T3P to give the amide 14g (R₁₀ = CI) and 14h (R₁₀ = OH), respectively. 14g and 14h can then be cyclized via ring-closing metathesis using a catalyst, such as Grubbs (II), in a suitable solvent, such as DCM, DCE, or toluene at elevated temperature, to give the macrocycle 14i (R₁₀ = CI) and 14j (R₁₀ = OH), respectively. The resulting alkenes can then be reduced with hydrogen over either palladium on carbon or platinum oxide to give 14k and 141. 14k can be reduced with ammonium acetate and palladium on carbon to reduce the chlorine to give 14m. Subsequent deprotection of 14m and 141 provides amines 14n (Rio = H) and 14o (Rio = OH). Compounds of the formulae 14n and 14o can be converted to compounds in this invention according to Scheme 15. Scheme 14

[00308] Representative regioisomeric pyridazine containing amide macrocycle intermediates useful for the synthesis of compounds of this invention are described in Scheme 14a. Using a modification of the Minisci reaction described by Cowden (Org. Lett., 5:4497-4499 (2003)), an appropriately protected glycine 14aa and 3,6- dichloropyridazine can be coupled at elevated temperature in the presence of silver nitrate, ammonium persulfate, and an acid, such as ammonium formate, in a solvent, such as water or a water/dimethylformamide mixture, to give compounds of the formulae 14ab. Compound 14ab can be further functionalized by deprotonation with nBuLi and subsequent alkylation with an appropriately substituted alkyl halide, for instance allyl bromide, to give compound 14ac. Suzuki-Miyaura coupling between chloropyridazine 14ac and an appropriately substituted aryl or heteroaryl boronic acid or ester 1 le in the presence of a base such as sodium carbonate using a precatalyst such as (Ph₃P)₄Pd provides, after separation of the enantiomers, aniline 14ad. Aniline 14ad can be converted to 14ae and 14af according to Scheme 7. Hydrogenolysis of the chloro under transfer hydrogenation conditions and Boc-deprotection will give compounds 14ag and 14ah. Compounds of the formulae 14ag and 14ah can be converted to compounds in this invention according to Scheme 15.

Scheme 14a

[00309] Representative compounds of this invention can then be made as shown in Scheme 15 using intermediates made in Schemes 2 to 13. The various substituted acids represented by formula 15b can be coupled with both 6- and 5-membered macrocycle amines represented by 15a using either coupling reagents or by converting them to acid chloride (like Vilsmeier reagent) and then treating the mixture with a base to afford the desired macrocycles of this invention. heme 15
