Patent Application
20230002404
The present disclosure relates to heterobicyclic cyclopropanecarboxamide compounds that affect the function of kinases and other proteins in a cell and that are useful as therapeutic agents or with therapeutic agents. In particular, these compounds are useful in the treatment of eye diseases such as glaucoma and retinal diseases, as anti-inflammatory agents, for the treatment of cardiovascular diseases, and for diseases characterized by abnormal growth, such as cancers.
A variety of hormones, neurotransmitters and biologically active substances control, regulate or adjust the functions of living bodies via specific receptors located in cell membranes. Many of these receptors mediate the transmission of intracellular signals by activating guanine nucleotide-binding proteins (G proteins) to which the receptor is coupled. Such receptors are generically referred to as G-protein coupled receptors (GPCRs) and include, among others, α-adrenergic receptors, β-adrenergic receptors, opioid receptors, cannabinoid receptors and prostaglandin receptors. The biological effects of activating or inhibiting these receptors is not direct but is mediated by a host of intracellular proteins. The importance of these secondary proteins has been recognized and modulation of this class is now being investigated as intervention points in disease states. One of the most important classes of these downstream effectors is the “kinase” class.
The various kinases play important roles in the regulation of various physiological functions. For example, kinases have been implicated in a number of disease states, including, but not limited to: cardiac indications such as angina pectoris, essential hypertension, myocardial infarction, supraventricular and ventricular arrhythmias, congestive heart failure, atherosclerosis, renal failure, diabetes, respiratory indications such as asthma, chronic bronchitis, bronchospasm, emphysema, airway obstruction, upper respiratory indications such as rhinitis, seasonal allergies, inflammatory disease, inflammation in response to injury, rheumatoid arthritis. The importance of p38 MAPK inhibitors in particular as new drugs for rheumatoid arthritis is reflected by the large number of compounds that has been developed over the last years (J. Westra and P. C. Limburg Mini-Reviews in Medicinal Chemistry Volume 6, Number 8, August 2006). Other conditions include chronic inflammatory bowel disease, glaucoma, hypergastrinemia, gastrointestinal indications such as acid/peptic disorder, erosive esophagitis, gastrointestinal hypersecretion, mastocytosis, gastrointestinal reflux, peptic ulcer, Zollinger-Ellison syndrome, pain, obesity, bulimia nervosa, depression, obsessive-compulsive disorder, organ malformations (e.g., cardiac malformations), neurodegenerative diseases such as Parkinson's Disease and Alzheimer's Disease, multiple sclerosis, Epstein-Barr infection and cancer (Nature Reviews Drug Discovery 2002, 1: 493-502). In other disease states, the role of kinases is only now becoming clear. The retina is a complex tissue composed of multiple interconnected cell layers, highly specialized for transforming light and color into electrical signals that are perceived by the brain. Damage or death of the primary light-sensing cells, the photoreceptors, results in devastating effects on vision. Despite the identification of numerous mutations that cause inherited retinal degenerations, the cellular and molecular mechanisms leading from the primary mutations to photoreceptor apoptosis are not well understood but may involve the wnt pathway (A S Hackam “The Wnt Signaling Pathway in Retinal Degeneration” IUBMB Life Volume 57, Number 6/June 2005).
The success of the tyrosine-kinase inhibitor ST1571 (Gleevec) in the treatment of chronic myelogenous leukemia (Nature Reviews Drug Discovery 2003, 2: 296-313) has spurred considerable efforts to develop other kinase inhibitors for the treatment of a wide range of other cancers (Nature Reviews Cancer 2003, 3: 650-665). The balance between the initiation and the inactivation of intracellular signals determines the intensity and duration of the response of the receptors to stimuli such as agonists. When desensitization occurs, the mediation or regulation of the physiological function mediated or regulated by the G proteins to which the receptors are coupled is reduced or prevented. For example, when agonists are administered to treat a disease or condition by activation of certain receptors, the receptors relatively quickly become desensitized from the action of the GRKs such that agonist administration may no longer result in therapeutic activation of the appropriate receptors. At that point, administration of the agonist no longer enables sufficient or effective control of or influence on the disease or condition intended to be treated.
Janus Kinases (or JAK) are a family of cytoplasmic protein tyrosine kinases. The JAK family plays a role in the cytokine-dependent regulation of proliferation and function of cells involved in immune response. Currently, there are four JAK family members are known JAK1, JAK2, JAK3, and TYK2. The JAKs usually associate with cytokine receptors in pairs as homodimers or heterodimers. Specific cytokines are associated with specific JAK pairings. Each of the four members of the JAK family is implicated in the signaling of at least one of the cytokines associated with inflammation. Binding of cytokine to a JAK-dependent cytokine receptor induces receptor dimerization which results in phosphorylation of tyrosine residues on the JAK kinase, effecting JAK activation. Phosphorylated JAKs, in turn, bind and phosphorylate various STAT proteins which dimerize, internalize in the cell nucleus and directly modulate gene transcription, leading, among other effects, to the downstream effects associated with inflammatory disease. There is recent evidence that the kinases ROCK1 and ROCK2 may also participate in similar interactions with the STAT enzymes. Inhibition of ROCK kinases has been noted to have an anti-inflammatory effect as well.
In view of the role that kinases play in many disease states, there is an urgent and continuing need for small molecule ligands which inhibit or modulate the activity of kinases. Without wishing to be bound by theory, it is thought that modulation of the activity of kinases, in particular ROCK and JAK kinases, by the compounds of the present disclosure is, at least in part, responsible for their beneficial effects.

Compounds described herein may exist in one or more particular geometric, optical, enantiomeric, diastereomeric, epimeric, atropic, stereoisomer, tautomeric, conformational, or anomeric forms, including but not limited to, cis- and trans-forms; E- and Z-forms; c-, t-, and r-forms; endo- and exo-forms; R-, S-, and meso-forms; D- and L-forms; d- and 1-forms; (+) and (−) forms; keto-, enol-, and enolate-forms; syn- and anti-forms; synclinal- and anticlinal-forms; α- and β-forms; axial and equatorial forms; boat-, chair-, twist-, envelope-, and half chair-forms; and combinations thereof, hereinafter collectively referred to as “isomers” (or “isomeric forms”).
In one embodiment, a compound described herein may be an enantiomerically enriched isomer of a stereoisomer described herein. For example, the compound may have an enantiomeric excess of at least about 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99%. Enantiomer, when used herein, refers to either of a pair of chemical compounds whose molecular structures have a mirror-image relationship to each other.
In one embodiment, a preparation of a compound disclosed herein is enriched for an isomer of the compound having a selected stereochemistry, e.g., R or S, corresponding to a selected stereocenter. For example, the compound has a purity corresponding to a compound having a selected stereochemistry of a selected stereocenter of at least about 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99%.
In one embodiment, a composition described herein includes a preparation of a compound disclosed herein that is enriched for a structure or structures having a selected stereochemistry, e.g., R or S, at a selected stereocenter. Exemplary R/S configurations can be those provided in an example described herein.
An “enriched preparation,” as used herein, is enriched for a selected stereoconfiguration of one, two, three or more selected stereocenters within the subject compound. Exemplary selected stereocenters and exemplary stereoconfigurations thereof can be selected from those provided herein, e.g., in an example described herein. By enriched is meant at least 60%, e.g., of the molecules of compound in the preparation have a selected stereochemistry of a selected stereocenter. In an embodiment it is at least 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99%. Enriched refers to the level of a subject molecule(s) and does not connote a process limitation unless specified.
Compounds may be prepared in racemic form or as individual enantiomers or diastereomers by either stereospecific synthesis or by resolution. The compounds may, for example, be resolved into their component enantiomers or diastereomers by standard techniques, such as the formation of stereoisomeric pairs by salt formation with an optically active base, followed by fractional crystallization and regeneration of the free acid. The compounds may also be resolved by formation of stereoisomeric esters or amides, followed by chromatographic separation and removal of the chiral auxiliary. Alternatively, the compounds may be resolved using a chiral chromatography column. The enantiomers also may be obtained from kinetic resolution of the racemate of corresponding esters using lipase enzymes.
Except as discussed below for tautomeric forms, specifically excluded from the term “isomers,” as used herein, are structural (or constitutional) isomers (i.e., isomers which differ in the connections between atoms rather than merely by the position of atoms in space). For example, a reference to a methoxy group, —OCH3, is not to be construed as a reference to its structural isomer, a hydroxymethyl group, —CH2OH. Similarly, a reference to ortho-chlorophenyl is not to be construed as a reference to its structural isomer, meta-chlorophenyl. However, a reference to a class of structures may well include structurally isomeric forms falling within that class (e.g., C3-alkyl or propyl includes n-propyl and iso-propyl; C4-alkyl or butyl includes n-, iso-, sec-, and tert-butyl; methoxyphenyl includes ortho-, meta-, and para-methoxyphenyl).
The above exclusion does not pertain to tautomeric forms, for example, keto-, enol-, and enolate-forms, as in, for example, the following tautomeric pairs: keto/enol, imine/enamine, amide/imino alcohol, amidine/amidine, nitroso/oxime, thioketone/enethiol, N-nitroso/hydroxyazo, and nitro/aci-nitro.
Note that specifically included in the term “isomer” are compounds with one or more isotopic substitutions. For example, H may be in any isotopic form, including 1H, 2H (D), and 3H (T); C may be in any isotopic form, including 12C, 13C, and 14C; O may be in any isotopic form, including 16O and 18O; and the like.
A compound described herein can be in the form of a salt, e.g., a pharmaceutically acceptable salt. The term “pharmaceutically acceptable salt” includes salts of the active compounds that are prepared with relatively nontoxic acids or bases, depending on the particular substituents found on the compounds described herein. Neutral forms of the compounds may be regenerated by contacting the salt with a base or acid and isolating the parent compound in a conventional manner. The parent form of the compound differs from the various salt forms in certain physical properties, such as solubility in polar solvents, but otherwise the salts are equivalent to the parent form of the compound for the purposes of this disclosure. Examples of pharmaceutically acceptable salts are discussed in Berge et al, 1977, “Pharmaceutically Acceptable Salts.” J. Pharm. Sci. Vol. 66, pp. 1-19. In an embodiment, the compound is present in mono-salt form. In embodiments, the compound is present in di-salt form.
For example, if the compound is anionic, or has a functional group which may be anionic (e.g., —COOH may be —COO−), then a salt may be formed with a suitable cation. Examples of suitable inorganic cations include, but are not limited to, alkali metal ions such as Na+ and K+, alkaline earth cations such as Ca2+ and Mg2+, and other cations. Examples of suitable organic cations include, but are not limited to, ammonium ion (i.e., NH4+) and substituted ammonium ions (e.g., NH3R1+, NH2R2+, NHR3+, NR4+). Examples of some suitable substituted ammonium ions are those derived from: ethylamine, diethylamine, triethylamine, butylamine, ethylenediamine, ethanolamine, diethanolamine, piperazine, benzylamine, phenylbenzylamine, choline, meglumine, and tromethamine, as well as dibasic amino acids, such as lysine and arginine.
If the compound is cationic, or has a functional group that may be cationic (e.g., —NH2 may be —NH3+), then a salt may be formed with a suitable anion. Examples of suitable inorganic anions include, but are not limited to, those derived from the following inorganic acids: hydrochloric, hydrobromic, hydroiodic, sulfuric, sulfurous, nitric, nitrous, phosphoric, and phosphorous.
Examples of suitable organic anions include, but are not limited to, those derived from the following organic acids: 2-acetyoxybenzoic, acetic, ascorbic, aspartic, benzoic, camphorsulfonic, cinnamic, citric, edetic, ethanedisulfonic, ethanesulfonic, fumaric, glucoheptonic, gluconic, glutamic, glycolic, hydroxymaleic, hydroxynaphthalene carboxylic, isethionic, lactic, lactobionic, lauric, maleic, malic, methanesulfonic, mucic, oleic, oxalic, palmitic, pamoic, pantothenic, phenylacetic, phenylsulfonic, propionic, pyruvic, salicylic, stearic, succinic, sulfanilic, tartaric, p-toluenesulfonic, and valeric. Examples of suitable polymeric organic anions include, but are not limited to, those derived from the following polymeric acids: tannic acid, carboxymethyl cellulose.
Unless otherwise specified, a reference to a particular compound also includes salt forms thereof.
It may be convenient or desirable to prepare, purify, and/or handle an active compound in a chemically protected form. The term “chemically protected form” is used herein in the conventional chemical sense and pertains to a compound in which one or more reactive functional groups are protected from undesirable chemical reactions under specified conditions (e.g., pH, temperature, radiation, solvent, and the like). In practice, well known chemical methods are employed to reversibly render unreactive a functional group, which otherwise would be reactive, under specified conditions. In a chemically protected form, one or more reactive functional groups are in the form of a protected or protecting group (also known as a masked or masking group or a blocked or blocking group). By protecting a reactive functional group, reactions involving other unprotected reactive functional groups can be performed, without affecting the protected group; the protecting group may be removed, usually in a subsequent step, without substantially affecting the remainder of the molecule. See, for example, Protective Groups in Organic Synthesis (T. Green and P. Wuts; 3rd Edition; John Wiley and Sons, 1999). Unless otherwise specified, a reference to a particular compound also includes chemically protected forms thereof.
A wide variety of such “protecting,” “blocking,” or “masking” methods are widely used and well known in organic synthesis. For example, a compound which has two nonequivalent reactive functional groups, both of which would be reactive under specified conditions, may be derivatized to render one of the functional groups “protected,” and therefore unreactive, under the specified conditions; so protected, the compound may be used as a reactant which has effectively only one reactive functional group. After the desired reaction (involving the other functional group) is complete, the protected group may be “deprotected” to return it to its original functionality.
A hydroxyl group may be protected as an ether (—OR) or an ester (—OC(O)R), for example, as: a t-butyl ether; a benzyl, benzhydryl (diphenylmethyl), or trityl (triphenylmethyl) ether; a trimethylsilyl or t-butyldimethylsilyl ether; or an acetyl ester (—OC(O)CH3, —OAc).
An aldehyde or ketone group may be protected as an acetal (RCH(OR)2) or ketal (R2C(OR)2), respectively, in which the carbonyl group (R2C═O) is converted to a diether (R2C(OR)2), by reaction with, for example, a primary alcohol. The aldehyde or ketone group is readily regenerated by hydrolysis using a large excess of water in the presence of acid.
An amine group may be protected, for example, as an amide (—NRC(O)R) or a urethane (—NRC(O)OR), for example, as: a methyl amide (—NHC(O)CH3); a benzyloxy amide (—NHC(O)OCH2C6H5, —NH-Cbz); as a tert-butoxy amide (—NHC(O)OC(CH3)3, —NH-Boc); a 2-biphenyl-2-propoxy amide (—NHCO(O)C(CH3)2C6H4C6H5, —NH-Bpoc), as a 9-fluorenylmethoxy amide (—NH-Fmoc), as a 6-nitroveratryloxy amide (—NH-Nvoc), as a 2-trimethylsilylethyloxy amide (—NH-Teoc), as a 2,2,2-trichloroethyloxy amide (—NH-Troc), as an allyloxy amide (—NH-Alloc), as a 2(-phenylsulphonyl)ethyloxy amide (—NH-Psec); or, in suitable cases (e.g., cyclic amines), as a nitroxide radical (>N—O«).
A carboxylic acid group may be protected as an ester, for example, as: an alkyl ester (e.g., a methyl ester; a t-butyl ester); a haloalkyl ester (e.g., a haloalkyl ester); a trialkylsilylalkyl ester; or an arylalkyl ester (e.g., a benzyl ester; a nitrobenzyl ester); or as an amide, for example, as a methyl amide.
A thiol group may be protected as a thioether (—SR), for example, as: a benzyl thioether; an acetamidomethyl ether (—S—CH2NHC(O)CH3)
In addition to salt forms, the present disclosure may also provide compounds that are in a prodrug form. Prodrugs of the compounds described herein are those compounds that readily undergo chemical changes under physiological conditions to provide the compounds described herein. Prodrugs can be converted to the compounds of the present disclosure by chemical or biochemical methods in an ex vivo environment. For example, prodrugs can be slowly converted to the compounds of the present disclosure when placed in a transdermal patch reservoir with or without a suitable enzyme or chemical reagent.
A compound described herein can also be modified by appending appropriate functionalities to enhance selective biological properties. Such modifications are known in the art and include those that increase biological penetration into a given biological system (e.g., blood, lymphatic system, central nervous system), increase oral availability, increase solubility to allow administration by injection, alter metabolism, and/or alter rate of excretion. Examples of these modifications include, but are not limited to, esterification with polyethylene glycols, derivatization with pivolates or fatty acid substituents, conversion to carbamates, hydroxylation of aromatic rings, and heteroatom substitution in aromatic rings.
Methods of synthesizing the herein described compounds will be evident to those of ordinary skill in the art. Synthetic chemistry transformations and protecting group methodologies (protection and deprotection) useful in synthesizing the compounds are known in the art and include, for example, those such as described in R. Larock, Comprehensive Organic Transformations, VCH Publishers (1989); T. W. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, 2d. Ed., John Wiley and Sons (1991); L. Fieser and M. Fieser, Fieser and Fieser's Reagents for Organic Synthesis, John Wiley and Sons (1994); and L. Paquette, ed., Encyclopedia of Reagents for Organic Synthesis, John Wiley and Sons (1995), and subsequent editions thereof.

An effective amount of a compound according to the present disclosure will vary with the particular condition being treated, the age and physical condition of the patient being treated, the severity of the condition, the duration of treatment, the nature of concurrent therapy, the route of administration, the particular pharmaceutically-acceptable carrier utilized, and like factors within the knowledge and expertise of the attending physician. For example, an effective amount of the compounds of the present disclosure for systemic administration is from about 0.01 to about 1000 μg/kg body weight, preferably from about 0.1 to about 100 μg/kg per body weight, most preferably form about 1 to about 50 μg/kg body weight per day. The transdermal dosages will be designed to attain similar serum or plasma levels, based upon techniques known to those skilled in the art of pharmacokinetics and transdermal formulations. Plasma levels for systemic administration are expected to be in the range of 0.01 to 100 ng/mL, more preferably from 0.05 to 50 ng/mL and most preferably from 0.1 to 10 ng/mL. While these dosages are based upon a daily administration rate, the compounds of the present disclosure may also be administered at other intervals, such as twice per day, twice weekly, once weekly, or once a month. One of ordinary skill in the art would be able to calculate suitable effective amounts for other intervals of administration.
The compounds of the present disclosure are useful in a method of reducing or decreasing intraocular pressure. The compounds of the present disclosure may be administered to a subject in need of treatment in an amount effective to reduce intraocular pressure. Thus, these compounds are useful in the treatment of glaucoma. The preferred route of administration for treating glaucoma is topically.
The exact amounts of each component in the topical composition depend on various factors. The amount of component A added to the topical composition is dependent on the IC50 of component A, typically expressed in nanomolar (nM) units. For example, if the IC50 of the medicament is 1 nM, the amount of component A will be from about 0.001 to about 0.3%. If the IC50 of the medicament is 10 nM, the amount of component A) will be from about 0.01 to about 1%. If the IC50 of the medicament is 100 nM, the amount of component A will be from about 0.1 to about 10%. If the amount of component A is outside the ranges specified above (i.e., lower), efficacy of the treatment may be reduced. One skilled in the art understands how to calculate and understand an IC50. The remainder of the composition, up to 100%, is component B.
The amount of the carrier employed in conjunction with component A is sufficient to provide a practical quantity of composition for administration per unit dose of the medicament.

The disclosure will be further explained by the following illustrative Examples that are to be considered to be non-limiting.
All compounds were initially prepared as 10 mM stocks in anhydrous dimethylsulfoxide (DMSO). A 20 μL aliquot of the 10 mM solutions was transferred to individual wells in column 1 of a 96-well polypropylene microtiter plate (Corning #3363) and diluted with DMSO to give a final compound concentration of 4 mM. Test compounds were then serially diluted 1:5 in DMSO for an 11-point concentration response and further diluted in the assay buffer bringing all compound concentrations to a final range of 100 μM to 10 μM in 2.5% DMSO. The assay was performed in white 96-well, flat-bottom, half-area, non-binding assay plate (Corning #3642) in assay buffer consisting of 20 mM HEPES (pH 7.5), 10 mM MgCl2*6H2O, 100 μM sodium orthovanadate, 0.05% CHAPS and 0.1% bovine serum albumin. A 10 μL aliquot of compound from each well of the intermediate dilution plate and 20 μL of a 2X substrate/enzyme solution containing acceptor substrate (800 nM RSK2 peptide KRRRLSSLRA (SEQ ID NO: 1)), ROCK2 enzyme (10 nM), or ROCK1 enzyme, and 1,4-Dithiothreitol (DTT, 2 uM) were added to all wells. The reaction was initiated by the addition of 10 μL of 4x stock solution ATP (2 μM). Reactions were thoroughly mixed manually, covered and allowed to incubate at room temperature for 75 min. Protein kinase activity was quantitated using Promega's KINASE-GLO™ luminescent Kinase Assay Kit according to the manufacturer's directions. ATP concentrations remaining in Test wells following the termination of the enzymatic reaction were compared against control wells containing equivalent amounts of DMSO containing no inhibitor (CTRL). ATP concentrations in both Test wells and CTRL wells were normalized against background (BKG) ATP concentrations in wells containing concentrations of inhibitor that completely inhibited the protein kinase under investigation (i.e. a concentration that prevented any consumption of ATP over the course of the incubation). Percent of Control (POC) values were determined for each concentration of compound tested according to the equation:
POC=((Test well value−BKG)/(CTRL−BKG))*100
IC50 values were calculated using the following 4-parameter logistic curve-fitting algorithm:
f(x)=(A+((B−A)/(1+((x/C){circumflex over ( )}D))))
IC50 values were converted to Ki values using the following Cheng-Prusoff Equation:
K
i
=IC
50/(1+([ATP]/Km ATP])).
Compounds were prepared in the exact same manner as described in the ROCK Kinase Assay with the exception to the substrate and enzyme. The JAK 2X substrate/enzyme solution consisted of acceptor substrate (800 nM Abl peptide EAIYAAPFAKKK (SEQ ID NO:2)), JAK2 or JAK3 enzyme (10 nM) and DTT (2 uM). All other steps and solutions remain identical to the ROCK Kinase Assay above. Results are shown above in Table 1.
Porcine Trabecular Meshwork cells (PTM) were isolated from freshly obtained enucleated porcine eyes. Immortalized Human Trabecular Meshwork cells (TM-1) were obtained through a kind gift from Donna Peters in the Department of Ophthalmology and Visual Sciences at the University of Wisconsin. Cells were plated onto fibronectin coated glass-bottom 96-well plates and allowed to attach overnight. Media was removed and replaced with test compound in media with 1% fetal bovine serum and incubated for various times. After incubation, cells were formaldehyde fixed, triton solubilized, and stained. PTM cells were stained with Alexa Fluor® 488 phalloidin (F-actin) and Hoechst 33342 (nuclei). TM-1 cells were stained with anti-paxillin followed by Alexa Fluor® 488 goat-anti-mouse IgG (focal adhesions) and Hoechst 33342 (nuclei). All staining reagents were obtained through Invitrogen. Images were collected on an INCell 2200 imager with a 20X objective. The actin fiber length and total area of focal adhesions were analyzed using custom algorithms developed in the INCell Developer Toolbox, v1.9.3. Data collected were converted to percent of control (untreated cells). Curves were fit to data in GraphPad Prizm using sigmoidal dose-response and constraining top and bottom to 100% and 0%, respectively.
