CROSS REFERENCE TO RELATED APPLICATIONS

This application is entitled to priority pursuant to 35 U.S.C. § 119(e) to U.S. provisional patent application No. 62/531,563, filed July 12, 2017, which is incorporated herein in its entirety.

FIELD OF THE INVENTION

The present invention relates generally to novel 5-memmbered and bicyclic heterocyclic amindes and their analogues thereof, which are inhibitors of Rho kinases, compositions containing them, and methods of using them, for example, for the treatment or prophylaxis of disorders associated with aberrant Rho kinase activity. BACKGROUND OF THE INVENTION

Rho-Kinase (ROCK) is a member of the serine-threonine protein kinase family. ROCK exists in two isofo ms, ROCK1 and ROCK2 (Ishizald, 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) that plays a key role in multiple cellular signaling pathways. ROCK and RhoA are ubiquitously expressed across tissues. The RhoA ROCK signaling pathway is involved in a number of cellular functions, such as ACTIN® organization, cell adhesion, cell migration, and cytokinesis (Riento, K. et al., Nat. Rev. Mol. Cell Biol., 4:446-456 (2003)). It is also directly involved in regulating smooth muscle contraction (Somlyo, A.P., Nature, 389:908-911 (1997)). Upon activation of its receptor, RhoA is activated, and, in turn, it activates ROCK. Activated ROCK

phosphorylates the myosin-binding subunit of myosin light chain phosphatase, which inhibits activity of the phosphatase and leads to contraction. Contraction of the smooth muscle in the vasculature increases blood pressure, leading to hypertension.

There is considerable evidence in the literature that the Rho A/ROCK signaling pathway plays an important role in signal transduction initiated by several vasoactive factors, for example angiotensin II (Yamakawa, T. et ai., Hypertension, 35:313-318 (2000)), urotension II (Sauzeau, V. et al., Circ. Res., 88: 1 102-1 104 (2001)), endothelin-1 (Tangkijvanich, P. et al., Hepatology, 33:74-80 (2001)), serotonin (Shimokawa, H., Jpn. Circ. J., 64: 1-12 (2000)), norepinephrine (Martinez, M.C. et al., A . J. Physiol, 279:H1228-H1238 (2000)) and platelet-derived growth factor (PDGF) (Kishi, H. et al., J. Biochem., 128:719-722 (2000)). Many of these factors are implicated in the pathogenesis of cardiovascular disease.

Additional studies in the literature, some using the known ROCK inhibitors fasudil (Asano, T. et ai., J. Pharmacol. Exp. Ther. , 241 :1033-1040 (1987)) or Ύ-27632 (Uehata, M. et al„ Nature, 389:990-994 (1997)) further illustrate the link between ROCK and cardiovascular disease. For example, ROCK expression and activity have been shown to be elevated in spontaneously hypertensive rats, suggesting a link to the development of hypertension in these animals (Mukai, Y. et al., FASEB J., 15:1062-1064 (2001)). The ROCK inhibitor Y-27632 (Uehata, M. et al., Nature, ibid.) was shown to significantly decrease blood pressure in three rat models of hypertension, including the spontaneously hypertensive rat, renal hypertensive rat and deoxycortone acetate salt hypertensive rat models, while having only a minor effect on blood pressure in control rats. This reiiiforces the link between ROCK and hypertension.

Other studies suggest a link between ROCK and atherosclerosis. For example, gene transfer of a dominant negative form of ROCK suppressed neointimal formation following balloon injury in porcine femoral arteries (Eto, Y. et al., Am. J. Physiol Heart Circ. Physiol, 278:H1744-H1750 (2000)). In a similar model, ROCK inhibitor Y-27632 also inhibited neointimal formation in rats (Sawada, N. et al., Circulation, 101 :2030-2033 (2000)). In a porcine model of IL-1 beta-induced coronary stenosis, long term treatment with the ROCK inhibitor fasudil was shown to progressively reduce coronary stenosis, as well as promote a regression of coronary constrictive remodeling (Shimokawa, H. et al., Cardiovasc. Res. , 51 : 169-177 (2001)).

Additional investigations suggest that a ROCK inhibitor would be useful in treating other cardiovascular diseases. For example, in a rat stroke model, fasudil was shown to reduce both the infarct size and neurologic deficit (Toshima, Y., Stroke, 31:2245-2250 (2000)). 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 (Kobayashi, N. et al., Cardiovasc. Res. , 55:757-767 (2002)). Other animal or clinical studies have implicated ROCK in additional diseases including coronary vasospasm (Shimokawa, H, et al., Cardiovasc. Res. , 43:1029-1039 (1999)), cerebral vasospasm (Sato, M. et al, Circ. Res. , 87:195-200 (2000)),

ischemia/reperfusion injury (Yada, T. et al., J. Am. Coll. Cardiol , 45:599-607 (2005)), pulmonary hypertension (Fukumoto, Y. et al., Heart, 91 :391-392 (2005)), angina (Shimokawa, H. et al, J. Cardiovasc. Pharmacol, 39:319-327 (2002)), renal disease (Satoh, S. et al, Eur. J. Pharmacol , 455:169-174 (2002)) and erectile dysfunction (Gonzalez-Cadavid, N.F. et al., Endocrine, 23:167-176 (2004)),

In another study, it has been demonstrated that inhibition of the RhoA/ROCK signaling pathway allows formation of multiple competing lamellipodia that disrupt the productive migration of monocytes (Wortliylake, R.A. et al., J. Biol. Chem., 278:13578- 13584 (2003)). It has also been reported that small molecule inhibitors of Rho Kinase are capable of inhibiting MCP-1 mediated chemotaxis in vitro (lijima, H., Bioorg. Med. Chem., 15:1022-1033 (2007)). Due to the dependence of immune cell migration upon the RhoA/ROCK signaling pathway one would anticipate inhibition of Rho Kinase should also provide benefit for diseases such as rheumatoid arthritis, psoriasis, and inflammatory bowel disease.

The above studies provide evidence for a link between ROCK and cardiovascular diseases including hypertension, atherosclerosis, restenosis, stroke, heart failure, coronary vasospasm, cerebral vasospasm, ischemia/reperfusion injury, pulmonary hypertension and angina, as well as renal disease and erectile dysfunction. 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)). Furthermore, Rho- kinase has been indicated as a drug target for the treatment of various other diseases, including airway inflammation and hyperresponsiveness (Henry, P. J. et al., Pulm.

Pharmacol Ther., 18:67-74 (2005)), cancer (Rattan, R. et al., J. Ne rosci. Res. , 83:243- 255 (2006); Lepley, D. et al, Cancer Res., 65:3788-3795 (2005)), fibrotic diseases (Jiang, C. et al, Int. J. Mol. Set, 13:8293-8307 (2012); Zhou, L. et al., Am. J. Nephrol, 34:468- 475 (2011)), as well as neurological disorders, such as spinal-cord injury, Alzheimer's disease, multiple sclerosis, stroke and neuropathic pain (Mueller, B.K. et al., Nat. Rev. Drug Disc, 4:387-398 (2005); Sun, X. et al, J. Neuroimmunol , 180: 126-134 (2006)). There remains an unmet medical need for new drugs to treat cardiovascular disease. In the 2012 update of Heart Disease and Stroke Statistics from the American Heart Association {Circulation, 125:e2-e220 (2012)), it was reported that cardiovascular disease accounted for 32.8% of all deaths in the U.S., with coronary heart disease accounting for ~1 in 6 deaths overall in the U.S.. Contributing to these numbers, it was found that -33.5% of the adult U.S. population was hypertensive, and it was estimated that in 2010 -6.6 million U.S. adults would have heart failure. Therefore, despite the number of medications available to treat cardiovascular diseases (CVD), including diuretics, beta blockers, angiotensin converting enzyme inhibitors, angiotensin blockers and calcium channel blockers, CVD remains poorly controlled or resistant to current medication for many patients.

Although there are many reports of ROCK inhibitors under investigation (see, for example, US 2012/0122842 Al, US 2010/0041645 Al, US 2008/0161297 Al, and Hu, E. et al., Exp. Opin, Ther. Targets, 9:715-736 (2005), and WO2014/113620, WO

2014/134388, WO 2014/134391, WO2015/002915, WO2015/002926, WO2016/010950, WO2016/028971, WO2016/112236, and WO2016/144936, of which the later nine references are assigned to the present applicant), fasudil is the only marketed ROCK inhibitor at this time. An i.v. formulation was approved in Japan for treatment of cerebral vasospasm. There remains a need for new therapeutics, including ROCK inhibitors, for the treatment of cardiovascular diseases, cancer, neurological diseases, renal diseases, fibrotic diseases, bronchial asthma, erectile dysfunction, and glaucoma.

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 witliin 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 diastereome ic 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.

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 0 atoms in the heterocycle exceeds 1, then these heteroatoms are not adjacent to one another.

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

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.

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

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

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., -O), 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).

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.

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.

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.

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.

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, toliienesulfo ic,

methanesulfonic, ethane disulfonic, oxalic, and isethionic.

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.

In addition, compounds of formula I may have prodrug forms. Any compound that will be converted in vivo to provide the bioactive agent (i.e., a compound of formula I) is a prodrug within the scope and spirit of the invention. Various forms of prodrugs are well known in the art. For examples of such prodrug derivatives, see:

a) Bundgaard, H., ed., Design of Prodrugs, Elsevier (1985), and Widder, K. et al., eds., Methods in Emymology, 112:309-396, Academic Press (1985);

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-ealkyl, Ci-ealkylbenzyl, 4-methoxybenzyl, indanyl, phthalyl, methoxymethyl, Ci-e alkanoyloxy-Ci-ealkyl (e.g. , acetoxy methyl, pivaloyloxymethyl or propionyloxymethyl), Ci-6alkoxycarbonyloxy-Ci-6alkyl (e.g., · methoxycarbonyl-oxymethyi or ethoxycarbonyloxymethyl, glycyloxymethyl, phenylglycyloxymethyl, (5-methyl-2-oxo-l ,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 Icnown in the art.

Preparation of prodrugs is well known in the ait 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. E ymology, VCHA and Wiley-VCH, Zurich, Switzerland (2003); Wermuth, C.G., ed., The Practice of Medicinal Chemistry, Academic Press, San Diego, CA (1999).

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 tiitium. Deuterium has one proton and one neutron in its nucleus and that has twice the mass of ordinary hydrogen. Deuterium can be represented by symbols such as " ² H" or "D". The term "deuterated" herein, by itself or used to modify a compound or group, refers to replacement of one or more hydrogen atom(s), which is attached to carbon(s), with a deuterium atom. Isotopes of carbon include ^l C and ¹⁴ C.

I sotopically -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.

"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 an N-halo, S(0) ₂ H, or S(0)H group, The term "solvate" means a physical association of a compound of this invention with one or more solvent, molecules, whether organic or inorganic.

In Vitro Assays

The effectiveness of compounds of the present invention as ROCK inhibitors can be determined in a 30 μΐ, assay containing 20 mM HEPES, pH 7.5, 20 mM MgCb, 0.015% Brij-35, 4 mM DTT, 5 μΜ ATP and 1.5 μΜ peptide substrate (FITC-AHA- AICRRRLSSLRA-OH) (SEQ ID NO. 1). Compounds were dissolved in DMSO so that the final concentration of DMSO was < 2%, and the reaction was initiated with Rho ldnase variants. After incubation, the reaction was terminated by the addition of EDTA and the phosphorylated and non-phosphorylated peptides separated using a LABCHIP® 3000 Reader (Caliper Life Sciences). Controls consisted of assays that did not contain compound, and backgrounds consisted of assays that contained enzyme and substrate but had EDTA from the beginning of the reaction to inhibit kinase activity. Compounds were tested in dose-response format, and the inhibition of ldnase activity was calculated at each concentration of compound. The inhibition data were fit using a curve-fitting program to determine the IC50; i.e., the concentration of compound required to inhibit 50%> of kinase activity.

Representative Examples were tested in the ROCK2 assay described above and found having ROCK2 inhibitory activity. Their ROCK2 inhibitory activity (IC50 values) of < 3 μΜ (3000 nM) was observed and shown in Table A below.

V. PHARMACEUTICAL COMPOSITIONS, FORMULATIONS AND

COMBINATIONS

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.

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 patient 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

-56- 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).

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 disorder.

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.

Compounds of this invention can also be administered by parenteral

administration (e.g. , intra- venous, intra-arterial, intramuscularly, or subcutaneously. When administered intra- enous 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.

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.

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.

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.

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, steaiylamine, or phosphatidylcholines.

Compounds of the present invention may also be coupled with soluble polymers as targetable drug earners. Such polymers can include polyvinylpyrrolidone, pyran copolymer, polyhydroxypropylmethacrylamide-phenol,

polyhydroxyethylaspartamidephenol, or polyethyleneoxide-poly lysine 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 amphipatbic block copolymers of hydrogels.

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.

Gelatin capsules may contain the active ingredient and powdered earners, 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.

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

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 benzalkonmm chloride, methyl-or propyl-paraben, and

chlorobutanol.

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.

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 ROCK. Such compounds may be provided in a commercial kit, for example, for use in pharmaceutical research involving ROCK, For example, a compound of the present invention could be used as a reference in an assay to compare its known activity to a compound with an unknown activity. This would ensure the experimenter that the assay was being performed properly and provide a basis for comparison, especially if the test compound was a derivative of the reference compound. When developing new assays or protocols, compounds according to the present invention could be used to test then- effectiveness.

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

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

The package insert is a label, tag, marker, etc. that recites information relating to the pharmaceutical composition located within the first container. The information recited will usually be determined by the regulatory agency governing the area in which the article of manufacture is to be sold (e.g., the United States Food and Drug

Administration). Preferably, the package insert specifically recites the indications for which the pharmaceutical composition has been approved. The package insert may be made of any material on which a person can read information contained therein or thereon. Preferably, the package insert is a printable material (e.g., paper, plastic, cardboard, foil, adhesive-backed paper or plastic, etc.) on which the desired information has been formed (e.g., printed or applied).

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

The compounds of the present invention may be synthesized by 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 ait 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.

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. Preparation of homochiral examples may be carried out by teclmiques 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.

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 ait 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.

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)). Scheme 1

Scheme 1 shows the synthesis of compound lg from spiroheptane alcohol la and heteroaryl nitrile lb. Spiroheptane alcohol la and heteroaiyl nitrile lb are either commercially available or can be prepared by known methods. Treatment of alcohol la with a base such as NaH, followed by addition to heteroaryl nitrile lb, where X is a leaving group such as F, CI, Br or mesylate. Alternatively, coupling between la and lb (when X = OH) can be accomplished via a Mitsunobu reaction, using reagents such as triphenylphosphine and DIAD. When Re = H, reaction with an electrophilic reagent in the presence of base affords product lc, where R ₆ is an alkyl or substituted alkyl group. R ₆ may be further derivatized after installation into lc or in subsequent compounds. Nitrile intermediate lc can be converted to the primary amide Id via treatment with KiCCb/MgO and H2O2. Removal of a protecting group (PG) on Id, via appropriate means based upon the particular protecting group, affords amine le. When R.6 = H, reductive animation with an appropriate ketone or aldehyde using a reagent such as NaBEbCN or Na(OAc) ₃ BH affords product le, where R¾ is an alkyl or substituted alkyl group. Re may be further derivatized after installation into le or in subsequent compounds. Amine le is converted directly to lg (amide, carbamate, or urea) by treatment with appropriate reagents. Amides can be formed via coupling of carboxylic acids, using a coupling reagent such as BOP, T3P or HATU, or via reaction with an acid chloride. Carbamates can be prepared via reaction with a chloroformate reagent and a base such as TEA or DIEA. Ureas may be formed via treatment with an isocyanate. Alternatively, reaction of amine le with 4- nitrophenyl chloroformate affords carb mate If. Treatment of 1 f with an alcohol in the presence of base affords the carbamate product lg. Treatment of If with an amine in the presence of base affords the urea product 1 g.

Scheme 2

Scheme 2 shows the synthesis of compound lg from spiroheptane alcohol la and heteroaryi ester 2a. Spiroheptane alcohol la and heteroaryl ester 2a are either

commercially available or can be prepared by known methods. Treatment of alcohol 1 a with a base such as NaH, followed by addition to heteroaryl ester 2a, where X is a leaving group such as F, CI, Br or mesylate. Alternatively, coupling between la and 2a (when X = OH) can be accomplished via a Mitsunobu reaction, using reagents such as

triphenyiphosphine and DIAD, Ester 2b can then be converted to amide Id, either directly by treatment with ammonia, or stepwise via saponification with LiOH and subsequent amide formation with ammonia and a coupling reagent such as BOP. Id is converted to lg, as shown in Scheme 1. Alternatively, Removal of a protecting group (PG) on Id, via appropriate means based upon the particular protecting group, affords an amine, which is converted to 2c (amide, carbamate, or urea) by treatment with appropriate reagents, as in Scheme 1. Ester 2c can be converted to amide lg as described above for the conversion of 2b to Id. Sche e 3

Scheme 1 shows the synthesis of hydantoiti 3b from carbamate If. Carbamate If can be treated with amino acid esters (where R = Me, Et and R3 = H, alkyl, aryl: either commercially available or prepared by known methods) to afford urea 3a. Urea 3a can then be cyclized to hydantoin 3b by treatment with NaOMe.
