This invention relates to novel compounds and pharmaceutical compositions comprising the novel compounds. More specifically, the invention relates to compounds useful as modulators of Rho-associated protein kinase (ROCK), for example ROCK1 and/or ROCK2 inhibitors. This invention also relates to processes for preparing the compounds, uses of the compounds and methods of treatment employing the compounds. The compounds of the invention may therefore be used in treating ROCK mediated diseases.
Rho-Kinase (ROCK) is a coiled-coil forming serine-threonine protein kinase family and exists in two isoforms, ROCK1 and ROCK2 (Ishizaki, T. et al, EMBO J.15: 1885-1893 (1996)). ROCK has been identified as an effector molecule of RhoA, a small GTP-binding protein (G protein). Both molecules are ubiquitously expressed across tissues and play key-roles in multiple cellular signalling pathways. Upon receptor activation RhoA activates ROCK that in turn controls several cellular functions including cell migration, cell adhesion, actin reorganisation, cytokinesis and smooth muscle contraction (Riento, K. et al, Nat. Rev. Mol. Cell Biol, 4:446-456 (2003)); (Somlyo, A. P., Nature, 389:908-911 (1997)). An aim of certain embodiments of the invention is to provide a modulator of ROCK, including both ROCK1 and ROCK2, for example an inhibitor of ROCK (ROCK1 and/or ROCK2).
Despite having similar kinase domains at 92% homology, ROCK1 and ROCK2 may have different downstream targets and therefore different modes of action in cellular physiology. ROCK2 for example specifically phosphorylate STAT3 in lymphocytes leading to Th17 cell differentiation and Treg suppression (Zanin-Zhorov A. et al, PNAS 111(47): 16814-16819 (2014)) whereas Myosin light chain (MLC) is specifically phosphorylated by ROCK1 in smooth muscle cells (Sebbagh M. et al. Nat Cell Biol 3: 346-352 (2001); showing a greater role for ROCK1 in vascular contraction leading to increases in blood pressure. SiRNA experiments have demonstrated distinct roles for ROCK1 and ROCK2 in many cell types for example in rat embryonic fibroblast cells where ROCK1 was found to be important for stress fiber formation and stabilization of focal adhesion sites, while ROCK2 activity was involved in phagocytosis of matrix-coated beads (Yoneda, A., et. al, J. Cell Biol. (2005). Therefore, an aim of certain embodiments of the invention is to provide a selective ROCK inhibitor, e.g. selective to ROCK1 inhibition or ROCK2 inhibition. Preferably, an aim of certain embodiments of the present invention is to provide a selective ROCK2 inhibitor.
ROCK deficient mice and small molecule inhibitors have helped the understanding of the roles that the ROCK isoforms play in disease and provided evidence that ROCK inhibitors will be useful for the treatment of several indications where unmet need is high including diabetes, inflammation, Alzheimer's hypertension and fibrosis. After feeding wild type and ROCK2(+/−) mice with a high fat diet for 17 weeks, it was shown that insulin resistance did not develop in the ROCK2(+/−) mice with normal insulin and GLUT4 expression observed. The myocardial performance index was also increased (Soliman et al., Am J Physiol Heart Circ Physiol. 309(1):H70-81 (2015)).
ROCK2 also plays a significant role in cardiac hypertrophy. Cardiomyocyte-specific deletion of ROCK2 display normal cardiac anatomy, function and hemodynamic parameters under basal conditions but following induction of cardiac hypertrophy induced by angiotensin II infusion the mice exhibited substantially less cardiac hypertrophy, intraventricular fibrosis, cardiac apoptosis, and oxidative stress compared to control mice. (Okamoto et al., FASEB J 4:1439-49 (2013)). The role of ROCK1 was further studied in a model of ischemia/reperfusion cardiomyopathy (I/RC) by occlusions of the left anterior descending artery. ROCK1 KO mice were protected from the development of URC-mediated myocardial dysfunction and had reduced cardiac fibrosis. Fibroblast formation from human peripheral blood mononuclear cells was impaired in cells with lower ROCK1 expression (Haudek et al., Cardiovasc Res. 83(3):511-8 (2009)). ROCK activity has also been shown to be increased in patients with myocardial function (Dong et al., Int J Cardiol 167(6):2813-9 (2013)). A combination of increased Rho kinase activity and N-terminal pro-B-type natriuretic peptide predicts worse cardiovascular outcome in patients with acute coronary syndrome.
ROCK2 also plays an important role in fibrosis: two reports have shown that bleomycin induced lung fibrosis is ameliorated in both ROCK1(+/−) and ROCK2(+/−) animals and mice with a targeted deletion of ROCK2 in cardiac fibroblasts showed reduced cardiac hypertrophy and fibrosis when infused with angiotensin II. (Shimizu T JACC Apr. 5, 2016 Volume 67, Issue 13; ATS 2014 A60. LUNG FIBROSIS: ANIMAL MODELS I). Furthermore, ROCK2 expression and function has been shown to be increased in bronchial epithelial tissue and fibrotic foci in idiopathic pulmonary fibrosis patients (Shimizu Y Int J Immunopathol Pharmacol. 27(1):37-44 (2014)).
A number of ATP competitive inhibitors of ROCK kinase activity have been developed with the non-isoform-selective Y-27632 and Fasudil being the most widely known and used. These inhibitors show a relatively high degree of specificity for ROCKs, however, when used at higher concentrations they can also inhibit other kinases such as protein kinase A and C family members and citron kinase (Ishizaki et al., 2000; Ikenoya et al., 2002). Fasudil was approved in Japan and China in 1995 for prevention and treatment of cerebral vasospasm following subarachnoid haemorrhage. In clinical studies, fasudil shows beneficial effects in patients with Pulmonary arterial hypertension, systemic hypertension, vasospastic angina, stroke, and chronic heart failure (Masumoto et al., 2001, 2002; Fukumoto et al., 2005; Kishi et al., 2005; Shibuya et al., 2005). Additional investigations suggest that a ROCK inhibitor would be useful in treating cardiovascular diseases. In a rat stroke model, Fasudil was shown to reduce both the infarct size and neurologic deficit and the ROCK inhibitor Y-27632 was shown to improve ventricular hypertrophy, fibrosis and function in a model of congestive heart failure in Dahl salt-sensitive rats ((Toshima, Y., Stroke, 31:2245-2250 (2000); Kobayashi, N. et al., Cardiovasc. Res., 55:757-767 (2002)). Other studies show a link between ROCK and atherosclerosis. In a porcine model of IL-1 beta-induced coronary stenosis, long term treatment with the Fasudil was shown to progressively reduce coronary stenosis, as well as promote a regression of coronary constrictive remodelling (Shimokawa, H. et al., Cardiovasc. Res., 51:169-177 (2001)). In a similar model, ROCK inhibitor Y-27632 also inhibited neointimal formation in rats (Sawada, N. et al., Circulation, 101:2030-2033 (2000)).
Furthermore, both Y27632 and Fasudil have demonstrated efficacy in the bleomycin induced lung fibrosis (Shimizu Y et al., Am J Respir Crit Care Med. 163(1):210-7 (2001)); Jiang C et al., Int J Mol Sci. 13(7):8293-307 (2012)) and Fasudil has been shown to be efficacious in a rat unilateral ureteral obstruction kidney fibrosis model (Shin-ichi S., Eur. J. Pharm. 29:169-174 (2002)) and against hepatic fibrosis in rats with type2 diabetes induced by a high fat diet combined with streptozotocin (Zhou H et al., Chin Med J, 127(2):225-31 (2014)). In addition, Fasudil treated mice were significantly protected mice from lung and skin fibrosis after repeated subcutaneous injections of hypochlorous acid (HOCI) (Bei Y et al., Exp Lung Res, 42(1):44-45 (2016)). These results provide further evidence that ROCK signalling is instrumental to fibrotic processes across a number of tissues and fibrotic diseases and underlines the value in targeting ROCK as an anti-fibrotic in cardiovascular and metabolic diseases.
A selective ROCK2 inhibitor (KD025) has been described that has also shown efficacious effects in inflammatory disease models and cells isolated from diseased patients via suppression of Th17 and T follicular helper (TFH) cells. KD025 effectively ameliorated chronic graft-versus-host disease (cGVHD) in two models: a full major histocompatibility complex (MHC) mismatch model of multiorgan system cGVHD with bronchiolitis obliterans syndrome and a minor MHC mismatch model of sclerodermatous GVHD. Treatment with KD025 resulted in normalization of pathogenic pulmonary function via suppression of antibody and collagen deposition in the lungs (Flynn R et al., Blood 127(17):2144-54 (2016)). KD025 suppression of ROCK2 signalling in normal human T cells or peripheral blood mononuclear cells from patients with active systemic lupus erythematosus (SLE) was also shown to decrease the number and function of TFH cells induced by activation ex vivo (Weiss J M et al., Sci Signal, 9(437):ra73 (2016)). Further ex-vivo stimulation of T-cells from healthy human subjects demonstrated that oral administration of KD025 was able to reduce the ability of T cells to secrete IL-21 and IL-17 by 90% and 60%, respectively (Zanin-Zhorov A et al., Proc Natl Acad Sci, 111(47):16814-9 (2014)). Given the demonstrated effect of ROCK on smooth muscle, ROCK inhibitors may also be useful in other diseases involving smooth muscle hyper-reactivity, including asthma and glaucoma (Shimokawa, H. et al., Arterioscler. Thromb. Vase. Biol., 25:1767-1775 (2005)). Selective suppression of ROCK2 therefore presents a novel opportunity to treat a number of auto-immune and inflammatory-fibrotic conditions.
ROCK also plays a significant role in pathologies of the central nervous system (CNS). For example, ROCK-signalling has been demonstrated to be elevated in the serum, spleen, brain and spinal cord of Multiple Sclerosis (MS) patients compared to healthy individuals. In vitro neuron injury with scratch and TNF-α stimulation also induces the up-regulation of ROCK activity. When serum of MS patients was co-cultured with mouse cortical neurons in vitro, MS serum caused neurite shortening and reduction of cell viability. Co-culture with Fasudil partially restored the synaptic morphology of the neurons strongly suggesting a neuro-protective effect of ROCK inhibition (Chen C et al., Neuromolecular Med. 17(4):465-65 (2015)). Intravitreal administration of Fasudil was able to improve the retinal function in the R6/2 mouse model of Huntington disease suggesting ROCK inhibition may be able to slow or reverse neuronal dysregulation (Li M et al., PloS One. 8(2):e56026 (2013)). Oral administration of Y-27632 was also able to improve coordination and balance in a rotarod performance test in the R6/2 model; the treatment also reduced the level of soluble huntingtin (Htt) protein (Li M et al., Neurobiol Dis. 36(3):413-20 (2009)). ROCKII interference (RI) with small hairpin RNA (ShRNA) also significantly improved movement disorder and attenuated dopaminergic (DA) neuron loss induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in a mouse model of Parkinson's disease. In addition, ROCK2 ShRNA inhibited the activation of M1 microglia in the substantia nigra (SN), exhibiting reduced activity of the TLR2/NF-κB signaling pathway and decreased expression levels of iNOS and inflammatory factors, including interleukin (IL)-1β and IL-6. (Zhang Q et al., Mol Med Rep. 14(6):4947-4956 (2016)). In another study Fasudil was also shown to have protective effects on the DN in the MPTP model. (Zhao Y et al., J Neurol Sci 353(1-2):28-37 (2015)). Further experiments with RNAi knockdown demonstrated that reduced expression of both ROCK1 and ROCK2 suppressed endogenous Aβ40 production in neurons and Aβ40 levels were reduced in brains of ROCK1 heterozygous knock-out mice compared to wild-type littermate controls suggesting ROCK may also be a valid target for the treatment of Alzheimer's disease (Henderson B et al., J Neurochem, 138(4):525-31 (2016)).
Several studies also demonstrate that ROCK inhibition will have utility in cancer therapy. Y-27632 and Fasudil have been shown to down regulate surviving expression in the pancreatic cell line PANC-1 and sensitised the cells to gemcitabine induced cell death. (Takeda H., Anticancer Res 36(12):6311-6318 (2016)). Oral administration of Fasudil has also been shown to reduce the tumour size in mouse transgenic model of human gastric cancer (Hinsenkamp I et al., Neoplasia 18(8):500-11 (2016)). Fasudil has also been shown to suppress proliferation and migration and induce apoptosis in urothelial cancer cells (Abe H et al., BMC Cancer 7; 14:412 (2014)).

“Meta” substitution is a substitution pattern where two substituents are on carbons one carbon removed from each other, i.e with a single carbon atom between the substituted carbons. In other words there is a substituent on the second atom away from the atom with another substituent. For example the groups below are meta substituted.
“Para” substitution is a substitution pattern where two substituents are on carbons two carbons removed from each other, i.e with two carbon atoms between the substituted carbons. In other words there is a substituent on the third atom away from the atom with another substituent. For example the groups below are para substituted.

Throughout the description the disclosure of a compound also encompasses pharmaceutically acceptable salts, solvates and stereoisomers thereof. Where a compound has a stereocentre, both (R) and (S) stereoisomers are contemplated by the invention, equally mixtures of stereoisomers or a racemic mixture are completed by the present application. Where a compound of the invention has two or more stereocentres any combination of (R) and (S) stereoisomers is contemplated. The combination of (R) and (S) stereoisomers may result in a diastereomeric mixture or a single diastereoisomer. The compounds of the invention may be present as a single stereoisomer or may be mixtures of stereoisomers, for example racemic mixtures and other enantiomeric mixtures, and diasteroemeric mixtures. Where the mixture is a mixture of enantiomers the enantiomeric excess may be any of those disclosed above. Where the compound is a single stereoisomer the compounds may still contain other diasteroisomers or enantiomers as impurities. Hence a single stereoisomer does not necessarily have an enantiomeric excess (e.e.) or diastereomeric excess (d.e.) of 100% but could have an e.e. or d.e. of about at least 85%, at least 60% or less. For example, the e.e. or d.e. may be 90% or more, 90% or more, 80% or more, 70% or more, 60% or more, 50% or more, 40% or more, 30% or more, 20% or more, or 10% or more.

Suitable base salts are formed from bases which form non-toxic salts. Examples include the aluminium, arginine, benzathine, calcium, choline, diethylamine, diolamine, glycine, lysine, magnesium, meglumine, olamine, potassium, sodium, tromethamine and zinc salts. Hemisalts of acids and bases may also be formed, for example, hemisulfate and hemicalcium salts. For a review on suitable salts, see “Handbook of Pharmaceutical Salts: Properties, Selection, and Use” by Stahl and Wermuth (Wiley-VCH, Weinheim, Germany, 2002).
Pharmaceutically acceptable salts of compounds of formula (I) may be prepared by one or more of three methods:
(i) by reacting the compound of the invention with the desired acid or base;
(ii) by removing an acid- or base-labile protecting group from a suitable precursor of the compound of the invention or by ring-opening a suitable cyclic precursor, for example, a lactone or lactam, using the desired acid or base; or
(iii) by converting one salt of the compound of the invention to another by reaction with an appropriate acid or base or by means of a suitable ion exchange column.
All three reactions are typically carried out in solution. The resulting salt may precipitate out and be collected by filtration or may be recovered by evaporation of the solvent. The degree of ionisation in the resulting salt may vary from completely ionised to almost non-ionised.
The compounds of the invention may 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 said solvent is water.
Included within the scope of the invention are complexes such as clathrates, drug-host inclusion complexes wherein, in contrast to the aforementioned solvates, the drug and host are present in stoichiometric or non-stoichiometric amounts. Also included are complexes of the drug containing two or more organic and/or inorganic components which may be in stoichiometric or non-stoichiometric amounts. The resulting complexes may be ionised, partially ionised, or non-ionised. For a review of such complexes, see J Pharm Sci, 64 (8), 1269-1288 by Haleblian (August 1975).
Hereinafter all references to compounds of any formula include references to salts, solvates and complexes thereof and to solvates and complexes of salts thereof.
The compounds of the invention include compounds of a number of formula as herein defined, including all polymorphs and crystal habits thereof, prodrugs and isomers thereof (including optical, geometric and tautomeric isomers) as hereinafter defined and isotopically-labelled compounds of the invention.
The present invention also includes all pharmaceutically acceptable isotopically-labelled compounds of the invention wherein one or more atoms are replaced by atoms having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number most commonly found in nature.
Examples of isotopes suitable for inclusion in the compounds of the invention include isotopes of hydrogen, such as 2H and 3H, carbon, such as 11C, 13C and 14C, chlorine, such as 36Cl, fluorine, such as 18F, iodine, such as 123I and 125I, nitrogen, such as 13N and 15N, oxygen, such as 15O, 17O and 18O, phosphorus, such as 32P, and sulphur, such as 35S.
Certain isotopically-labelled compounds, for example, those incorporating a radioactive isotope, are useful in drug and/or substrate tissue distribution studies. The radioactive isotopes tritium, i.e. 3H, and carbon-14, i.e. 14C, are particularly useful for this purpose in view of their ease of incorporation and ready means of detection.
Substitution with heavier isotopes such as deuterium, i.e. 2H, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances.
Before purification, the compounds of the present invention may exist as a mixture of enantiomers depending on the synthetic procedure used. The enantiomers can be separated by conventional techniques known in the art. Thus the invention covers individual enantiomers as well as mixtures thereof.
For some of the steps of the process of preparation of the compounds of the invention, it may be necessary to protect potential reactive functions that are not wished to react, and to cleave said protecting groups in consequence. In such a case, any compatible protecting radical can be used. In particular methods of protection and deprotection such as those described by T.W. GREENE (Protective Groups in Organic Synthesis, A. Wiley-Interscience Publication, 1981) or by P. J. Kocienski (Protecting groups, Georg Thieme Verlag, 1994), can be used. All of the above reactions and the preparations of novel starting materials used in the preceding methods are conventional and appropriate reagents and reaction conditions for their performance or preparation as well as procedures for isolating the desired products will be well-known to those skilled in the art with reference to literature precedents and the examples and preparations hereto.

The reaction was stirred at 25° C. for 18 h, forming a white precipitate. The reaction was concentrated in vacuo and dissolved in water and the solution was purified directly by ion exchange chromatography (SCX, eluting with 1 M NH3 in MeOH). The solvent was removed in vacuo and the gummy residue was dissolved in DCM and a white solid immediately precipitated. The solid was triturated with diethyl ether and filtered. The solid was then dried under vacuum for 3 days to give 4-[5-[(4-chloro-1H-indazol-5-yl)amino]-1-methyl-1,2,4-triazol-3-yl]-N-ethyl-2-fluoro-benzamide (50 mg, 0.12 mmol, 60% yield) as a white solid.

Further sodium bis(trimethylsilyl)amide solution (1.0 M in THF, 28.75 mL) was added and the reaction was stirred for 20 min. The mixture was quenched with sat. aq. NH4Cl (150 mL) and extracted with EtOAc (250 mL). The layers were separated, and the aqueous layer extracted with further EtOAc (2×100 mL). The combined organics were dried over MgSO4. and concentrated in vacuo. The solid residue was triturated with diethyl ether and filtered, washed with further diethyl ether to give N-(5-bromo-2-methyl-1,2,4-triazol-3-yl)-4-chloro-1-tetrahydropyran-2-yl-indazol-5-amine (19.75 g, 47.97 mmol, 83% yield) as a white solid.

The reaction mixture was fully degassed with bubbling nitrogen. [1,1′-bis(diphenylphosphino)ferrocene]palladium(II) chloride dichloromethane complex (23 mg, 0.03 mmol) was then added followed by further degassing and then the reaction was heated to 90° C. for 4 h. The reaction was reduced in vacuo onto silica and purified on a 4 g silica column eluting with 25-100% EtOAc in Pet. Ether to give 4-[5-[(4-chloro-1-tetrahydropyran-2-yl-indazol-5-yl)amino]-1-methyl-1,2,4-triazol-3-yl]-N-ethyl-2-fluoro-benzamide (100 mg, 0.19 mmol, 67% yield) as a pale yellow oil.

tert-butyl 3,3-difluoro-4-(trifluoromethylsulfonyloxy)pyrrolidine-1-carboxylate (1500 mg, 4.22 mmol), prepared following WO2017103611 example 160, was dissolved in DMF (20 mL) and cooled in an ice bath under N2 atmosphere. tetrabutylammonium azide (1200 mg, 4.22 mmol) in DMF (20 mL) was added slowly over 15 min via an addition funnel. The reaction mixture was stirred in the cold bath and allowed to warm to ambient temperature gradually and stirred for 3 h. The reaction was diluted with ethyl acetate (50 mL), washed with sat. aq. NaHCO3(×2) and brine (×2). The organic phase was dried over a phase separator and purged with vacuum/N2 (3 times) followed by the addition of palladium, 10 wt. % on carbon powder, dry (150 mg, 1.4 mmol). 3 cycles vacuum/H2 were then performed and the reaction was left stirring at RT overnight under an atmosphere of hydrogen. The crude was filtered through a plug of Celite™ and the solvent removed in vacuo.
