PYRAZOLE DERIVATIVES AS PLASMA KALLIKREIN INHIBITORS

This invention relates to enzyme inhibitors that are inhibitors of plasma kallikrein and to pharmaceutical compositions containing and the uses of, such inhibitors. Background to the Invention

The heterocyclic derivatives of the present invention are inhibitors of plasma kallikrein and have a number of therapeutic applications, particularly in the treatment of retinal vascular permeability associated with diabetic retinopathy and diabetic macular edema. Plasma kallikrein is a trypsin-like serine protease that can liberate kinins from kininogens (see K. D.

Bhoola et al., "Kallikrein-Kinin Cascade", Encyclopeclia of Respiratory Medicine, p483-493; J. W. Bryant et al., "Human plasma kallikrein-kinin system: physiological and biochemical parameters" Cardiovascular and haematological agents in medicinal chemistry, 7, p234-250, 2009; K. D. Bhoola et al.,

Pharmacological Rev., 1992, 44, 1; and D. J. Campbell, "Towards understanding the kallikrein-kinin system: insights from the measurement of kinin peptides", Brazilian Journal of Medical and Biological Research 2000, 33, 665-677). It is an essential member of the intrinsic blood coagulation cascade although its role in this cascade does not involve the release of bradykinin or enzymatic cleavage.

Plasma prekallikrein is encoded by a single gene and synthesized in the liver. It is secreted by hepatocytes as an inactive plasma prekallikrein that circulates in plasma as a heterodimer complex bound to high molecular weight kininogen which is activated to give the active plasma kallikrein. Kinins are potent mediators of inflammation that act through G protein-coupled receptors and antagonists of kinins (such as bradykinin antagonists) have previously been investigated as potential therapeutic agents for the treatment of a number of disorders (F. Marceau and D. egoli, Nature Rev., Drug Discovery, 2004, 3, 845-852).

Plasma kallikrein is thought to play a role in a number of inflammatory disorders. The major inhibitor of plasma kallikrein is the serpin CI esterase inhibitor. Patients who present with a genetic deficiency in CI esterase inhibitor suffer from hereditary angioedema (HAE) which results in intermittent swelling of face, hands, throat, gastro-intestinal tract and genitals. Blisters formed during acute episodes contain high levels of plasma kallikrein which cleaves high molecular weight kininogen liberating bradykinin leading to increased vascular permeability. Treatment with a large protein plasma kallikrein inhibitor has been shown to effectively treat HAE by preventing the release of bradykinin which causes increased vascular permeability (A. Lehmann "Ecallantide (DX-88), a plasma kallikrein inhibitor for the treatment of hereditary angioedema and the prevention of blood loss in on-pump cardiothoracic surgery" Expert Opin. Biol. Ther. 8, pll87-99). The plasma kallikrein-kinin system is abnormally abundant in patients with advanced diabetic macular edema. It has been recently published that plasma kallikrein contributes to retinal vascular dysfunctions in diabetic rats (A. Clermont et al. "Plasma kallikrein mediates retinal vascular dysfunction and induces retinal thickening in diabetic rats" Diabetes, 2011, 60, pl590-98). Furthermore, administration of the plasma kallikrein inhibitor ASP-440 ameliorated both retinal vascular permeability and retinal blood flow abnormalities in diabetic rats. Therefore a plasma kallikrein inhibitor should have utility as a treatment to reduce retinal vascular permeability associated with diabetic retinopathy and diabetic macular edema.

Plasma kallikrein also plays a role in blood coagulation. The intrinsic coagulation cascade may be activated by factor XII (FXII). Once FXII is activated (to FXIIa), FXIIa triggers fibrin formation through the activation of factor XI (FXI) thus resulting in blood coagulation. Plasma kallikrein is a key component in the intrinsic coagulation cascade because it activates FXII to FXIIa, thus resulting in the activation of the intrinsic coagulation pathway. Furthermore, FXIIa also activates further plasma prekallikrein resulting in plasma kallikrein. This results in positive feedback amplification of the plasma kallikrein system and the intrinsic coagulation pathway (Tanaka et al. (Thrombosis Research 2004, 113, 333-339); Bird et al.

(Thrombosis and Haemostasis, 2012, 107, 1141-50). Contact of FXII in the blood with negatively charged surfaces (such as the surfaces of external pipes or the membrane of the oxygenator that the blood passes during cardiopulmonary bypass surgery) induces a conformational change in zymogen FXII resulting in a small amount of active FXII (FXIIa). The formation of FXIIa triggers the formation of plasma kallikrein resulting in blood coagulation, as described above. Activation of FXII to FXIIa can also occur in the body by contact with negatively charged surfaces on various sources (e.g. bacteria during sepsis, NA from degrading cells), thus resulting in disseminated intravascular coagulation (Tanaka et al. (Thrombosis Research 2004, 113, 333-339)).

Therefore, inhibition of plasma kallikrein would inhibit the blood coagulation cascade described above, and so would be useful in the treatment of disseminated intravascular coagulation and blood coagulation during cardiopulmonary bypass surgery where blood coagulation is not desired. For example, Katsuura et al. (Thrombosis Research, 1996, 82, 361-368) showed that administration of a plasma kallikrein inhibitor, PKSI-527, for LPS-induced disseminated intravascular coagulation significantly suppressed the decrease in platelet count and fibrinogen level as well as the increase in FDP level which usually occur in disseminated intravascular coagulation. Bird et al. (Thrombosis and

Haemostasis, 2012, 107, 1141-50) showed that clotting time increased, and thrombosis was significantly reduced in plasma kallikrein-deficient mice. evenko et al. (Blood, 2011, 118, 5302-5311) showed that the reduction of plasma prekallikrein levels in mice using antisense oligonucleotide treatment resulted in antithrombotic effects. Tanaka et al. (Thrombosis Research 2004, 113, 333-339) showed that contacting blood with DX-88 (a plasma kallikrein inhibitor) resulted in an increase in activated clotting time (ACT). Lehmann et al. (Expert Opin. Biol. Ther. 2008, 1187-99) showed that Ecallantide (a plasma kallikrein inhibitor) was found to delay contact activated induced coagulation. Lehmann et al. conclude that Ecallantide "had in vitro anticoagulant effects as it inhibited the intrinsic pathway of coagulation by inhibiting plasma kallikrein". Plasma kallikrein also plays a role in the inhibition of platelet activation, and therefore the cessation of bleeding. Platelet activation is one of the earliest steps in hemostasis, which leads to platelet plug formation and the rapid cessation of bleeding following damage to blood vessels. At the site of vascular injury, the interaction between the exposed collagen and platelets is critical for the retention and activation of platelets, and the subsequent cessation of bleeding.

Once activated, plasma kallikrein binds to collagen and thereby interferes with collagen-mediated activation of platelets mediated by GPVI receptors (Liu et al. (Nat Med., 2011, 17, 206-210)). As discussed above, plasma kallikrein inhibitors reduce plasma prekallikrein activation by inhibiting plasma kallikrein-mediated activation of factor XII and thereby reducing the positive feedback amplification of the kallikrein system by the contact activation system.

Therefore, inhibition of plasma kallikrein reduces the binding of plasma kallikrein to collagen, thus reducing the interference of plasma kallikrein in the cessation of bleeding. Therefore plasma kallikrein inhibitors would be useful in the treatment of treating cerebral haemorrhage and bleeding from post operative surgery. For example, Liu et al. (Nat Med., 2011, 17, 206-210) demonstrated that systemic administration of a small molecule PK inhibitor, ASP-440, reduced hematoma expansion in rats. Cerebral hematoma may occur following intracerebral haemorrhage and is caused by bleeding from blood vessels into the surrounding brain tissue as a result of vascular injury. Bleeding in the cerebral haemorrhage model reported by Liu et al. was induced by surgical intervention involving an incision in the brain parenchyma that damaged blood vessels. These data demonstrate that plasma kallikrein inhibition reduced bleeding and hematoma volume from post operative surgery. Bjorkqvist et al. (Thrombosis and Haemostasis, 2013, 110, 399- 407) demonstrated that aprotinin (a protein that inhibits serine proteases including plasma kallikrein) may be used to decrease postoperative bleeding. Other complications of diabetes such as cerebral haemorrhage, nephropathy, cardiomyopathy and neuropathy, all of which have associations with plasma kallikrein may also be considered as targets for a plasma kallikrein inhibitor. Synthetic and small molecule plasma kallikrein inhibitors have been described previously, for example by Garrett et al. ("Peptide aldehyde...." J. Peptide Res. 52, p62-71 (1998)), T. Griesbacher et al.

("Kininogenase inhibitors" WO92/04371), D. M. Evans et al. (Immunolpharmacology, 32, pll5-116 (1996)), Szelke et al. ("Kininogen inhibitors" WO95/07921), Antonsson et al.

Res 27, pl929-34 (1994)), Kettner et al. (US 5,187,157), N. Teno et al. (Chem. Pharm. Bull. 41, pl079-1090 (1993)), W. B. Young et al. ("Small molecule inhibitors of plasma kallikrein" Bioorg. Med. Chem. Letts. 16, p2034-2036 (2006)), Okada et al. ("Development of potent and selective plasmin and plasma kallikrein inhibitors and studies on the structure-activity relationship" Chem. Pharm. Bull. 48, pl964-72 (2000)), Steinmetzer et al. ("Trypsin-like serine protease inhibitors and their preparation and use" WO08/049595), Zhang et al. ("Discovery of highly potent small molecule kallikrein inhibitors" Medicinal Chemistry 2, p545-553 (2006)), Sinha et al. ("Inhibitors of plasma kallikrein" WO08/016883), Shigenaga et al. ("Plasma Kallikrein Inhibitors" WO2011/118672), and Kolte et al. ("Biochemical characterization of a novel high-affinity and specific kallikrein inhibitor", British Journal of Pharmacology (2011), 162(7), 1639-1649). Also, Steinmetzer et al. ("Serine protease inhibitors" WO2012/004678) describes cyclized peptide analogs which are inhibitors of human plasmin and plasma kallikrein.

To date, no small molecule synthetic plasma kallikrein inhibitor has been approved for medical use. The molecules described in the known art suffer from limitations such as poor selectivity over related enzymes such as KLKl, thrombin and other serine proteases, and poor oral availability. The large protein plasma kallikrein inhibitors present risks of anaphylactic reactions, as has been reported for Ecallantide. Thus there remains a need for compounds that selectively inhibit plasma kallikrein, that do not induce anaphylaxis and that are orally available. Furthermore, the vast majority of molecules in the known art feature a highly polar and ionisable guanidine or amidine functionality. It is well known that such functionalities may be limiting to gut permeability and therefore to oral availability. For example, it has been reported by Jamie J. Chilcote and Sukanto Sinha ("ASP-634: An Oral Drug Candidate for Diabetic MacularEdema", A VO 2012 May 6 ^th - May 9 ^th , 2012, Fort Lauderdale, Florida, Presentation 2240) that ASP-440, a benzamidine, suffers from poor oral availability. It is further reported that absorption may be improved by creating a prodrug such as ASP-634. However, it is well known that prodrugs can suffer from several drawbacks, for example, poor chemical stability and potential toxicity from the inert carrier or from unexpected metabolites. In another report, indole amides are claimed as compounds that might overcome problems associated with drugs possessing poor or inadequate ADME-tox and

physicochemical properties although no inhibition against plasma kallikrein is presented or claimed (Griffioen et al, "Indole amide derivatives and related compounds for use in the treatment of neurodegenerative diseases", WO2010, 142801). BioCryst Pharmaceuticals Inc. have reported the discovery of the orally available plasma kallikrein inhibitor BCX4161 ("BCX4161, An Oral Kallikrein Inhibitor: Safety and Pharmacokinetic Results Of a Phase 1 Study In Healthy Volunteers", Journal of Allergy and Clinical Immunology, Volume 133, Issue 2, Supplement, February 2014, page AB39 and "A Simple, Sensitive and Selective Fluorogenic Assay to Monitor Plasma Kallikrein Inhibitory Activity of BCX4161 in Activated Plasma", Journal of Allergy and Clinical Immunology, Volume 133, Issue 2, Supplement February 2014, page AB40). However, human doses are relatively large, currently being tested in proof of concept studies at doses of 400 mg three times daily.

There are only few reports of plasma kallikrein inhibitors that do not feature guanidine or amidine functionalities. One example is Brandl et al. ("N-((6-amino-pyridin-3-yl)methyl)-heteroaryl-carboxamides as inhibitors of plasma kallikrein" WO2012/017020), which describes compounds that feature an amino- pyridine functionality. Oral efficacy in a rat model is demonstrated at relatively high doses of 30 mg/kg and 100 mg/kg but the pharmacokinetic profile is not reported. Thus it is not yet known whether such compounds will provide sufficient oral availability or efficacy for progression to the clinic. Other examples are Brandl et al. ("Aminopyridine derivatives as plasma kallikrein inhibitors" WO2013/111107) and Flohr et al. ("5-membered heteroarylcarboxamide derivatives as plasma kallikrein inhibitors" WO2013/111108). However, neither of these documents report any in vivo data and therefore it is not yet known whether such compounds will provide sufficient oral availability or efficacy for progression to the clinic. Another example is Allan et al. "Benzylamine derivatives" WO2014/108679.

Therefore there remains a need to develop new plasma kallikrein inhibitors that will have utility to treat a wide range of disorders, in particular to reduce retinal vascular permeability associated with diabetic retinopathy and diabetic macular edema. Preferred compounds will possess a good pharmacokinetic profile and in particular will be suitable as drugs for oral delivery. Summary of the Invention

"Prodrug" refers to a compound which is convertible in vivo by metabolic means (e.g. by hydrolysis, reduction or oxidation) to a compound of the invention. Suitable groups for forming prodrugs are described in 'The Practice of Medicinal Chemistry, 2 ^nd Ed. pp561-585 (2003) and in F. J. Leinweber, Drug Metab. Res., 1987, 18, 379.

The compounds of the invention can exist in both unsolvated and solvated forms. The term 'solvate' is used herein to describe a molecular complex comprising the compound of the invention and a stoichiometric amount of one or more pharmaceutically acceptable solvent molecules, for example, ethanol. The term 'hydrate' is employed when the solvent is water.

Where compounds of the invention exist in one or more geometrical, optical, enantiomeric, diastereomeric and tautomeric forms, including but not limited to cis- and irons-forms, E- and Z-forms, R-, S- and meso-forms, keto-, and enol-forms, unless otherwise stated a reference to a particular compound includes all such isomeric forms, including racemic and other mixtures thereof. Where appropriate such isomers can be separated from their mixtures by the application or adaptation of known methods (e.g. chromatographic techniques and recrystallisation techniques). Where appropriate such isomers can be prepared by the application or adaptation of known methods (e.g. asymmetric synthesis).

A reference to a particular compound also includes all isotopic variants. In the context of the present invention, references herein to "treatment" include references to curative, palliative and prophylactic treatment. General Methods

The compounds of the invention should be assessed for their biopharmaceutical properties, such as solubility and solution stability (across pH), permeability, etc., in order to select the most appropriate dosage form and route of administration for treatment of the proposed indication. They may be administered alone or in combination with one or more other compounds of the invention or in combination with one or more other drugs (or as any combination thereof). Generally, they will be administered as a formulation in association with one or more pharmaceutically acceptable excipients. The term 'excipient' is used herein to describe any ingredient other than the compound(s) of the invention which may impart either a functional (i.e., drug release rate controlling) and/or a nonfunctional (i.e., processing aid or diluent) characteristic to the formulations. The choice of excipient will to a large extent depend on factors such as the particular mode of administration, the effect of the excipient on solubility and stability, and the nature of the dosage form.

Compounds of the invention intended for pharmaceutical use may be administered as a solid or liquid, such as a tablet, capsule or solution. Pharmaceutical compositions suitable for the delivery of compounds of the present invention and methods for their preparation will be readily apparent to those skilled in the art. Such compositions and methods for their preparation may be found, for example, in Remington's Pharmaceutical Sciences, 19th Edition (Mack Publishing Company, 1995).

Accordingly, the present invention provides a pharmaceutical composition comprising a compound of the invention and a pharmaceutically acceptable carrier, diluent or excipient.

For the treatment of conditions such as retinal vascular permeability associated with diabetic retinopathy and diabetic macular edema, the compounds of the invention may be administered in a form suitable for injection into the ocular region of a patient, in particular, in a form suitable for intra- vitreal injection. It is envisaged that formulations suitable for such use will take the form of sterile solutions of a compound of the invention in a suitable aqueous vehicle. The compositions may be administered to the patient under the supervision of the attending physician.

The compounds of the invention may also be administered directly into the blood stream, into subcutaneous tissue, into muscle, or into an internal organ. Suitable means for parenteral administration include intravenous, intraarterial, intraperitoneal, intrathecal, intraventricular, intraurethral, intrasternal, intracranial, intramuscular, intrasynovial and subcutaneous. Suitable devices for parenteral administration include needle (including microneedle) injectors, needle-free injectors and infusion techniques.

Parenteral formulations are typically aqueous or oily solutions. Where the solution is aqueous, excipients such as sugars (including but not restricted to glucose, manitol, sorbitol, etc.), salts, carbohydrates and buffering agents (preferably to a pH of from 3 to 9), but, for some applications, they may be more suitably formulated as a sterile non-aqueous solution or as a dried form to be used in conjunction with a suitable vehicle such as sterile, pyrogen-free water.

Parenteral formulations may include implants derived from degradable polymers such as polyesters (i.e., polylactic acid, polylactide, polylactide-co-glycolide, polycapro-lactone, polyhydroxybutyrate), polyorthoesters and polyanhydrides. These formulations may be administered via surgical incision into the subcutaneous tissue, muscular tissue or directly into specific organs.

The preparation of parenteral formulations under sterile conditions, for example, by lyophilisation, may readily be accomplished using standard pharmaceutical techniques well known to those skilled in the art.

The solubility of compounds of the invention used in the preparation of parenteral solutions may be increased by the use of appropriate formulation techniques, such as the incorporation of co-solvents and/or solubility-enhancing agents such as surfactants, micelle structures and cyclodextrins. In one embodiment, the compounds of the invention may be administered orally. Oral administration may involve swallowing, so that the compound enters the gastrointestinal tract, and/or buccal, lingual, or sublingual administration by which the compound enters the blood stream directly from the mouth.

Formulations suitable for oral administration include solid plugs, solid microparticulates, semi-solid and liquid (including multiple phases or dispersed systems) such as tablets; soft or hard capsules containing multi- or nano-particulates, liquids, emulsions or powders; lozenges (including liquid-filled); chews; gels; fast dispersing dosage forms; films; ovules; sprays; and buccal/mucoadhesive patches.

Formulations suitable for oral administration may also be designed to deliver the compounds of the invention in an immediate release manner or in a rate-sustaining manner, wherein the release profile can be delayed, pulsed, controlled, sustained, or delayed and sustained or modified in such a manner which optimises the therapeutic efficacy of the said compounds. Means to deliver compounds in a rate- sustaining manner are known in the art and include slow release polymers that can be formulated with the said compounds to control their release.

Examples of rate-sustaining polymers include degradable and non-degradable polymers that can be used to release the said compounds by diffusion or a combination of diffusion and polymer erosion. Examples of rate-sustaining polymers include hydroxypropyl methylcellulose, hydroxypropyl cellulose, methyl cellulose, ethyl cellulose, sodium carboxymethyl cellulose, polyvinyl alcohol, polyvinyl pyrrolidone, xanthum gum, polymethacrylates, polyethylene oxide and polyethylene glycol.

Liquid (including multiple phases and dispersed systems) formulations include emulsions, solutions, syrups and elixirs. Such formulations may be presented as fillers in soft or hard capsules (made, for example, from gelatin or hydroxypropylmethylcellulose) and typically comprise a carrier, for example, water, ethanol, polyethylene glycol, propylene glycol, methylcellulose, or a suitable oil, and one or more emulsifying agents and/or suspending agents. Liquid formulations may also be prepared by the reconstitution of a solid, for example, from a sachet.

The compounds of the invention may also be used in fast-dissolving, fast-disintegrating dosage forms such as those described in Liang and Chen, Expert Opinion in Therapeutic Patents, 2001, 11 (6), 981-986.

The formulation of tablets is discussed in Pharmaceutical Dosage Forms: Tablets, Vol. 1, by H. Lieberman and L. Lachman (Marcel Dekker, New York, 1980). For administration to human patients, the total daily dose of the compounds of the invention is typically in the range 0.1 mg and 10,000 mg, or between 1 mg and 5000 mg, or between 10 mg and 1000 mg depending, of course, on the mode of administration. If administered by intra-vitreal injection a lower dose of between 0.0001 mg (0.1 μg) and 0.2 mg (200 μg) per eye is envisaged, or between 0.0005 mg (0.5 μg) and 0.05 mg (50 μg) per eye.

The total dose may be administered in single or divided doses and may, at the physician's discretion, fall outside of the typical range given herein. These dosages are based on an average human subject having a weight of about 60kg to 70kg. The physician will readily be able to determine doses for subjects whose weight falls outside this range, such as infants and the elderly. Synthetic Methods

The compounds of the present invention can be prepared according to the procedures of the following schemes and examples, using appropriate materials, and are further exemplified by the specific examples provided herein below. Moreover, by utilising the procedures described herein, one of ordinary skill in the art can readily prepare additional compounds that fall within the scope of the present invention claimed herein. The compounds illustrated in the examples are not, however, to be construed as forming the only genus that is considered as the invention. The examples further illustrate details for the preparation of the compounds of the present invention. Those skilled in the art will readily understand that known variations of the conditions and processes of the following preparative procedures can be used to prepare these compounds.

The compounds of the invention may be isolated in the form of their pharmaceutically acceptable salts, such as those described previously herein above. It may be necessary to protect reactive functional groups (e.g. hydroxy, amino, thio or carboxy) in intermediates used in the preparation of compounds of the invention to avoid their unwanted participation in a reaction leading to the formation of the compounds. Conventional protecting groups, for example those described by T. W. Greene and P. G. M. Wuts in "Protective groups in organic chemistry" John Wiley and Sons, 4 ^th Edition, 2006, may be used. For example, a common amino protecting group suitable for use herein is tert-butoxy carbonyl (Boc), which is readily removed by treatment with an acid such as trifluoroacetic acid or hydrogen chloride in an organic solvent such as dichloromethane. Alternatively the amino protecting group may be a benzyloxycarbonyl (Z) group which can be removed by hydrogenation with a palladium catalyst under a hydrogen atmosphere or 9- fluorenylmethyloxycarbonyl (Fmoc) group which can be removed by solutions of secondary organic amines such as diethylamine or piperidine in an organic solvent. Carboxyl groups are typically protected as esters such as methyl, ethyl, benzyl or tert-butyl which can all be removed by hydrolysis in the presence of bases such as lithium or sodium hydroxide. Benzyl protecting groups can also be removed by hydrogenation with a palladium catalyst under a hydrogen atmosphere whilst tert-butyl groups can also be removed by trifluoroacetic acid. Alternatively a trichloroethyl ester protecting group is removed with zinc in acetic acid. A common hydroxy protecting group suitable for use herein is a methyl ether, deprotection conditions comprise refluxing in 48% aqueous HBr for 1-24 hours, or by stirring with borane tribromide in dichloromethane for 1-24 hours. Alternatively where a hydroxy group is protected as a benzyl ether, deprotection conditions comprise hydrogenation with a palladium catalyst under a hydrogen atmosphere.

In Scheme 1, the amine 2 is coupled to an acid 1 to give the compound 3. This coupling is typically carried out using standard coupling conditions such as hydroxybenzotriazole and a carbodiimide, such as water soluble carbodiimide, in the presence of an organic base. Other standard coupling methods include the reaction of acids with amines in the presence of 2-(lH-benzotriazole-l-yl)-l,l,3,3- tetramethylaminium hexafluorophosphate, 2-(3H-[l,2,3]triazolo[4,5-b]pyridin-3-yl)-l,l,3,3- tetramethylisouronium hexafluorophosphate(V), benzotriazole-l-yl-oxy-tris-pyrrolidino-phosphoium hexaffluorophosphate or bromo-trispyrolidino-phosphoium hexafluorophosphate in the presence of organic bases such as triethylamine, diisopropylethylamine or N-methylmorpholine. Alternatively the amide formation can take place via an acid chloride in the presence of an organic base. Such acid chlorides can be formed by methods well known in the literature, for example reaction of the acid with oxalyl chloride or thionyl chloride. Alternatively, the amide formation can take place via activation of the carboxylic acid using carbonyl diimidazole.

Scheme 1

Alternatively compounds of the invention can be prepared using the route outlined in Scheme 2a. The acid 4 can be coupled to an amine 2 using suitable coupling methods as previously described to give compound 5. In a typical second step the nitrogen of the heterocyclic ring is alkylated with compound 6 to give compound 7. The alkylation can be carried out in the presence of a base such as potassium carbonate, cesium carbonate, sodium carbonate or sodium hydride in which case the leaving group is a halide or sulphonate. Alternatively the alkylation may be carried out using an alcohol under Mitsunobu conditions in the presence of triphenylphosphine.

In a variation of Scheme 2a compounds according to general formula I can be prepared using the route outlined in Scheme 2b. Scheme 2b differs from Scheme 2a in that the moiety Y is equal to N therefore a protecting group strategy may be employed and the synthetic steps carried out in a different order. The pyrazole carboxylic acid, protected as an ester (PG) as described previously, compound 8, is alkylated with compound 6. The alkylation can be carried out in the presence of a base such as potassium carbonate, cesium carbonate, sodium carbonate or sodium hydride in which case the leaving group is a halide or sulphonate. Alternatively the alkylation may be carried out using an alcohol under Mitsunobu conditions in the presence of triphenylphosphine. In this case there are two possible nitrogens for the alkylation to occur at therefore there is the possibility of two regioisomers 9 and 10 being formed. Compounds 9 and 10 may be separated at this stage or at a subsequent stage in the synthesis using separation methods well known to those skilled in the art, for example by chromatography or by fractional crystallisation. The protecting group of compound 9 is removed by hydrolysis to give the corresponding acid 11 using standard methods as described previously. Compound 11 can be coupled to an amine 2 using suitable coupling methods as previously described to give compound 12.

Scheme 2b

Alternatively compounds according to the invention can be prepared using the route outlined in Scheme 3. The pyrrole 17 can be formed in two steps the first of which involves reaction of the sodium salt of an alkyl ketoacetate 13, typically protected with a protecting group (PG) as described previously, with a chloroketone 14 in the presence of a base such as potassium carbonate to give compound 15 which in a typical second step is reacted with the amine 16 in the presence of an acid such as but not limited to sulphonic acid derivatives e.g. p-toluenesulphonic acid to yield compound 17 which in a typical third step is subsequently hydrolysed to the corresponding acid 18 using standard methods as described previously. In a typical fourth step the acid 18 can be coupled to an amine 2 using suitable coupling methods as previously described to give compound 19.

Scheme 3

The amine, compound 2 can be prepared using conventional synthetic methods for example, but not limited to, the routes outlined in Scheme 4. The nitrile of compound 20 is reduced by standard reducing agents including but not limited to lithium aluminium hydride, sodium borohydride, sodium borohydride and nickel chloride, sodium borohydride and cobalt chloride, borane, and catalytic hydrogenation over a catalyst such as palladium, platinum or aney nickel. In some cases, for example when the reducing agent is sodium borohydride or catalytic hydrogenation is employed, it is possible to carry out in situ protection of the resulting amino group, for example resulting in the carbamate 21, for example tert- butoxy carbamate. This may be helpful to enable for example purification by chromatography of the intermediate compound 21. The protecting group is subsequently removed using standard conditions as described reviously to give compound 2.

Determination of enzyme selectivity

Human serine protease enzymes plasmin, thrombin and trypsin were assayed for enzymatic activity using an appropriate fluorogenic substrate. Protease activity was measured by monitoring the accumulation of liberated fluorescence from the substrate over 5 minutes. The linear rate of fluorescence increase per minute was expressed as percentage (%) activity. The Km for the cleavage of each substrate was determined by standard transformation of the Michaelis-Menten equation. The compound inhibitor assays were performed at substrate Km concentration and activities were calculated as the concentration of inhibitor giving 50% inhibition (IC ₅ o) of the uninhibited enzyme activity (100%).

Data acquired from these assays are shown in Table 12 below: Table 12 (Selectivity data)

Solubility data

Solubility was determined in water and 0.1N HCI (aq). Test compounds were incubated at 1 mg/mL for 24 hrs at 37 °C on a shaking platform (500 rpm). Samples were taken at 1, 4 and 24 hrs and centrifuged at 15,000 g for 10 min. Test compound concentration in the supernatant was determined by LCMS against a standard curve.

In vitro ADME data

In vitro permeability was determined using the Caco-2 model for oral absorption. The methodology was adapted from standard published methods (Wang Z, Hop C.E., Leung K.H. and Pang J. (2000) J Mass Spectrom 35(1); 71-76). The Caco-2 monolayers were established in a Biocoat™ HTS fibrillar collagen 24 well multiwell insert system (1.0 μιη, PET membrane, Corning 354803) in which 200,000 cells were seeded into each insert and maintained over 3 days before being utilised in the permeability assay. For the assay, 50 μΜ test compound is added to the apical side of the inserts and incubated for 1 hour at 37 °C on a shaking platform (120 rpm). Apical to basolateral transport was determined by measuring the test article in both compartments by LCMS following the 1 hour incubation. The integrity of the Caco-2 monolayers was confirmed by two methods, (i) comparison of pre- and post-experiment transepithelial electrical resistance (TEER) and, (ii) assessment of Lucifer Yellow flux.

The intrinsic clearance was determined using standard published methods (Obach RS (1999) Drug Metab Dispos 27(11); 1350-135). Rat or human liver microsomes (0.5 mg/mL; Corning) were incubated with 5 μΜ test compound at 37 °C on a shaking platform (150 rpm). Samples were taken at 0, 6, 12, 18, 24 and 60 min and test compound concentrations were determined by LCMS against a calibration curve. The intrinsic clearance (Clint) was calculated using methodology described by Obach (Obach RS et al. (1997) J Pharmacol Exp Ther 283: 46-58.) or Lau (Lau YY et al (2002). Drug Metab Dispos 30: 1446-1454).

Plasma Protein Binding (PPB) and Predicted Clearance

The fraction unbound in plasma was determined using ThermoScientific™ Pierce™ Rapid Equilibrium Dialysis Technology (Single-Use plate with inserts, 8K MWCO). 5 μΜ test compound was spiked into human or rat plasma (300 μί) and dialysed against 146.5 mM phosphate buffer (500 μί) for 5 hrs at 37°C, shaking at 1200 rpm. Reference samples from the non-dialysed plasma were taken before the incubation to enable an assessment of recovery. Test compound concentrations were determined in plasma and buffer compartments by LCMS against a calibration curve. The fraction unbound in plasma was determined using standard methodology (Waters NJ et al (2008) J Pharm Sci 97(10); 4586-95). Results are presented as percent plasma protein bound (%PPB).

The predicted plasma clearance (CIp) is calculated using the well-stirred model (Rowland M, Benet LZ, and Graham GG. Clearance concepts in pharmacokinetics. J Pharmacokinet Biopharm. (1973) 1:123- 136.), one of several models that can be used to extrapolate the in vitro data. The model assumes instantaneous and complete mixing of drug within the liver and is a function of intrinsic clearance, hepatic blood flow and free fraction of drug in the blood. The predicted plasma clearance in mL/min/kg is presented as a percentage of hepatic blood flow (LBF). Example Predicted in vivo Predicted in vivo rat

Pharmacokinetic studies of the compounds in Table 13 were performed to assess the pharmacokinetics following a single oral dose in male Sprague-Dawley rats. Two rats were given a single po dose of 5 mL/kg of a nominal 2 mg/mL (10 mg/kg) composition of test compound in vehicle. Following dosing, blood samples were collected over a period of 24 hours. Sample times were 5, 15 and 30 minutes then 1, 2, 4, 6, 8 and 12 hours. Following collection, blood samples were centrifuged and the plasma fraction analysed for concentration of test compound by LCMS. Oral exposure data acquired from these studies are shown below:
