The present invention relates to compounds useful as inhibitors of MK2 kinases. The invention also provides pharmaceutically acceptable compositions comprising compounds of the present invention and methods of using said compositions in the treatment of various disorders.
The search for new therapeutic agents has been greatly aided in recent years by a better understanding of the structure of enzymes and other biomolecules associated with diseases. One important class of enzymes that has been the subject of extensive study is protein kinases.
Protein kinases constitute a large family of structurally related enzymes that are responsible for the control of a variety of signal transduction processes within the cell. Protein kinases are thought to have evolved from a common ancestral gene due to the conservation of their structure and catalytic function. Almost all kinases contain a similar 250-300 amino acid catalytic domain. The kinases may be categorized into families by the substrates they phosphorylate (e.g., protein-tyrosine, protein-serine/threonine, lipids, etc.).
Mitogen-activated protein kinase-activated protein kinase 2 (MAPKAP K2 or MK2) mediates multiple p38 MAPK-dependent cellular responses. MK2 is an important intracellular regulator of the production of cytokines, such as tumor necrosis factor alpha (TNF-α), interleukin 6 (IL-6) and interferon gamma (IFNγ), that are involved in many acute and chronic inflammatory diseases, e.g. rheumatoid arthritis and inflammatory bowel disease. MK2 resides in the nucleus of non-stimulated cells and upon stimulation, it translocates to the cytoplasm and phosphorylates and activates tuberin and HSP27. MK2 is also implicated in heart failure, brain ischemic injury, the regulation of stress resistance and the production of TNF-α. (see Deak et al., EMBO. 17:4426-4441 (1998); Shi et al., Biol. Chem. 383:1519-1536 (2002); Staklatvala., Curr. Opin. Pharmacol. 4:372-377 (2004), and Shiroto et al., J. Mol. Cardiol. 38:93-97 (2005)).
Many diseases are associated with abnormal cellular responses triggered by protein kinase-mediated events as described above. These diseases include, but are not limited to, autoimmune diseases, inflammatory diseases, bone diseases, metabolic diseases, neurological and neurodegenerative diseases, cancer, cardiovascular diseases, allergies and asthma, Alzheimer's disease, and hormone-related diseases. Accordingly, there remains a need to find protein kinase inhibitors useful as therapeutic agents.

As used herein, the term “pharmaceutically acceptable salt” refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge et al., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19, incorporated herein by reference. Pharmaceutically acceptable salts of the compounds of this invention include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid or malonic acid or by using other methods used in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and the like.

Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, loweralkyl sulfonate and aryl sulfonate.
Unless otherwise stated, structures depicted herein are also meant to include all isomeric (e.g., enantiomeric, diastereomeric, and geometric (or conformational)) forms of the structure; for example, the R and S configurations for each asymmetric center, Z and E double bond isomers, and Z and E conformational isomers. Therefore, single stereochemical isomers as well as enantiomeric, diastereomeric, and geometric (or conformational) mixtures of the present compounds are within the scope of the invention. Unless otherwise stated, all tautomeric forms of the compounds of the invention are within the scope of the invention.
Combinations of substituents and variables envisioned by this invention are only those that result in the formation of stable compounds. The term “stable”, as used herein, refers to compounds which possess stability sufficient to allow manufacture and which maintains the integrity of the compound for a sufficient period of time to be useful for the purposes detailed herein (e.g., therapeutic or prophylactic administration to a subject).
The recitation of a listing of chemical groups in any definition of a variable herein includes definitions of that variable as any single group or combination of listed groups. The recitation of an embodiment for a variable herein includes that embodiment as any single embodiment or in combination with any other embodiments or portions thereof.
The term “biological sample”, as used herein, includes, without limitation, cell cultures or extracts thereof, biopsied material obtained from a mammal or extracts thereof; and blood, saliva, urine, feces, semen, tears, or other body fluids or extracts thereof. Inhibition of activity of a protein kinase, for example, MK2 or a mutant thereof, in a biological sample is useful for a variety of purposes that are known to one of skill in the art. Examples of such purposes include, but are not limited to, blood transfusion, organ transplantation, biological specimen storage, and biological assays.
As used herein, a “disease or disorder associated with MK2” or, alternatively, “an MK2-mediated disease or disorder” means any disease or other deleterious condition in which MK2, or a mutant thereof, is known or suspected to play a role.
The term “subject”, as used herein, means a mammal and includes human and animal subjects, such as domestic animals (e.g., horses, dogs, cats, etc.). The terms “subject” and “patient” are used interchangeably. In some embodiments, the “patient” or “subject” means an animal, preferably a mammal, and most preferably a human.
The term “pharmaceutically acceptable carrier, adjuvant, or vehicle” refers to a non-toxic carrier, adjuvant, or vehicle that does not destroy the pharmacological activity of the compound with which it is formulated. Pharmaceutically acceptable carriers, adjuvants or vehicles that may be used in the compositions of this invention include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-based substances, polyethylene glycol, sodium carboxymethylcellulose, polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers, polyethylene glycol and wool fat. The amount of compounds of the present invention that may be combined with the carrier materials to produce a composition in a single dosage form will vary depending upon the host treated, the particular mode of administration, etc. Preferably, provided compositions are formulated so that a dosage of between 0.01 to about 100 mg/kg, or about 0.1 mg/kg to about 50 mg/kg, and preferably from about 1 mg/kg to about 25 mg/kg, of subject body weight/day of the inhibitor can be administered to a patient receiving these compositions to obtain the desired therapeutic effect. The amount of a compound of the present invention in the composition will also depend upon the particular compound in the composition.
The expression “unit dosage form” as used herein refers to a physically discrete unit of a provided compound and/or compositions thereof appropriate for the subject to be treated. It will be understood, however, that the total daily usage of the active agent (i.e., compounds and compositions of the present invention) will be decided by the attending physician within the scope of sound medical judgment. The specific effective dose level for any particular subject (i.e., patient) or organism will depend upon a variety of factors including the disorder being treated and the severity of the disorder; activity of specific active agent employed; specific composition employed; age, body weight, general health, sex and diet of the subject; time of administration, route of administration, and rate of excretion of the specific active agent employed; duration of the treatment; and like factors well known in the medical arts.
The term “parenteral” as used herein includes subcutaneous, intravenous, intramuscular, intra-articular, intra-synovial, intrasternal, intrathecal, intrahepatic, intralesional and intracranial injection or infusion techniques.
As used herein, a “therapeutically effective amount” means an amount of a substance (e.g., a therapeutic agent, composition, and/or formulation) that elicits a desired biological response. In some embodiments, a therapeutically effective amount of a substance is an amount that is sufficient, when administered as part of a dosing regimen to a subject suffering from or susceptible to a disease, disorder, and/or condition, to treat, diagnose, prevent, and/or delay the onset of the disease, disorder, and/or condition. As will be appreciated by those of ordinary skill in this art, the effective amount of a substance may vary depending on such factors as the desired biological endpoint, the substance to be delivered, the target cell or tissue, etc. For example, the effective amount of a provided compound in a formulation to treat a disease, disorder, and/or condition is the amount that alleviates, ameliorates, relieves, inhibits, prevents, delays onset of, reduces severity of and/or reduces incidence of one or more symptoms or features of the disease, disorder, and/or condition. In some embodiments, a “therapeutically effective amount” is at least a minimal amount of a provided compound, or composition containing a provided compound, which is sufficient for treating one or more symptoms of an MK2-mediated disease or disorder.
As used herein, the terms “treatment,” “treat,” and “treating” refer to partially or completely alleviating, inhibiting, delaying onset of, preventing, ameliorating and/or relieving a disorder or condition, or one or more symptoms of the disorder or condition, as described herein. In some embodiments, treatment may be administered after one or more symptoms have developed. In some embodiments, the term “treating” includes preventing or halting the progression of a disease or disorder. In other embodiments, treatment may be administered in the absence of symptoms. For example, treatment may be administered to a susceptible individual prior to the onset of symptoms (e.g., in light of a history of symptoms and/or in light of genetic or other susceptibility factors). Treatment may also be continued after symptoms have resolved, for example to prevent or delay their recurrence. Thus, in some embodiments, the term “treating” includes preventing relapse or recurrence of a disease or disorder.
As used herein, the term “inhibitor” is defined as a compound that binds to and/or inhibits the target protein kinase, MK2, with measurable affinity. In certain embodiments, an inhibitor has an IC50 and/or binding constant of less than about 50 μM, less than about 1 μM, less than about 500 nM, less than about 100 nM, or less than about 10 nM.
The terms “measurable affinity” and “measurably inhibit,” as used herein, means a measurable change in MK2 activity between a sample comprising a compound of the present invention, or composition thereof, and MK2, and an equivalent sample comprising MK2, in the absence of said compound, or composition thereof.
As used herein, the term “irreversible” or “irreversible inhibitor” refers to an inhibitor (i.e. a compound) that is able to be covalently bonded to a kinase in a substantially non-reversible manner. That is, whereas a reversible inhibitor is able to bind to (but is generally unable to form a covalent bond with) a kinase, and therefore can become dissociated from the kinase, an irreversible inhibitor will remain substantially bound to a kinase once covalent bond formation has occurred. Irreversible inhibitors usually display time dependency, whereby the degree of inhibition increases with the time with which the inhibitor is in contact with the enzyme. In certain embodiments, an irreversible inhibitor will remain substantially bound to a kinase once covalent bond formation has occurred and will remain bound for a time period that is longer than the life of the protein.
Methods for identifying if a compound is an irreversible inhibitor are known to one of ordinary skill in the art. Such methods include, but are not limited to, enzyme kinetic analysis of the inhibition profile of the compound with a kinase, the use of mass spectrometry of the protein drug target modified in the presence of the inhibitor compound, discontinuous exposure, also known as “washout,” experiments, and the use of labeling, such as radiolabelled inhibitor, to show covalent modification of the enzyme, as well as other methods known to one of skill in the art.
As used herein, the term “drug resistance” refers to changes in the wild-type nucleic acid sequence coding a target protein, and/or the amino acid sequence of the target protein, and/or the amino acid sequence of another protein, which changes decrease or abolish the inhibitory effect of the inhibitor on the target protein. Without wishing to be bound by any particular theory, it is believed that certain compounds of the present invention, i.e., compounds that are irreversible kinase inhibitors, may be effective inhibitors of drug resistant forms of protein kinases.
According to one aspect, the present invention provides a compound of Formula I:
or a pharmaceutically acceptable salt thereof, wherein:
Deuterium (D or 2H) is a stable, non-radioactive isotope of hydrogen and has an atomic weight of 2.0144. Hydrogen naturally occurs as a mixture of the isotopes 1H (hydrogen or protium), D (2H or deuterium), and T (3H or tritium). It will be appreciated that the designation “hydrogen” in hydrogen-containing chemical compounds actually represents a mixture of hydrogen and about 0.015% deuterium.
Complete deuteration, or 100% deuteration, at any one site can be difficult to achieve in the laboratory. When a deuterium atom is indicated at a given site on any compound described herein, it is understood that a small percentage of hydrogen may still be present. Such compounds are said to be enriched with deuterium. Deuterium-enriched compounds are prepared via synthesis utilizing appropriately enriched starting materials. As used herein, the terms “deuterium-enriched” or “deuterium enrichment” refer to a compound, or a particular site of said compound, which comprises deuterium in an amount that is greater than its natural isotopic abundance (0.015%). Accordingly, in some embodiments, the present invention provides compounds comprising deuterium at a given site, wherein the percentage or level of deuterium incorporation is greater than its natural isotopic abundance.

In some embodiments, a composition of this invention is formulated for oral administration to a patient.
Compounds and compositions, according to method of the present invention, are administered using any amount and any route of administration effective for treating or lessening the severity of a disorder provided herein (i.e., an MK2-mediated disease or disorder). The exact amount required will vary from subject to subject, depending on the species, age, and general condition of the subject, the severity of the infection, the particular agent, its mode of administration, and the like. Compounds of the invention are preferably formulated in unit dosage form for ease of administration and uniformity of dosage.
Compositions of the present invention may be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally, intraperitoneally, intracisternally or via an implanted reservoir. In some embodiments, the compositions are administered orally, intraperitoneally or intravenously.
Sterile injectable forms of the compositions of this invention may be aqueous or oleaginous suspension. These suspensions may be formulated according to techniques known in the art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium.
For this purpose, any bland fixed oil may be employed including synthetic mono- or di-glycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions may also contain a long-chain alcohol diluent or dispersant, such as carboxymethyl cellulose or similar dispersing agents that are commonly used in the formulation of pharmaceutically acceptable dosage forms including emulsions and suspensions. Other commonly used surfactants, such as Tweens, Spans and other emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or other dosage forms may also be used for the purposes of formulation.
Injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.
In order to prolong the effect of a compound of the present invention, it is often desirable to slow the absorption of the compound from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the compound then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered compound form is accomplished by dissolving or suspending the compound in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the compound in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of compound to polymer and the nature of the particular polymer employed, the rate of compound release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the compound in liposomes or microemulsions that are compatible with body tissues.

MK2 Kinase
MAP kinase-activated protein kinase 2 (“MK2”) is an enzyme that in humans is encoded by the MAPKAPK2 gene. The MAPKAPK2 gene encodes a member of the Ser/Thr protein kinase family and two transcript variants encoding two different isoforms have been found. MK2 is regulated through direct phosphorylation by p38 MAP kinase.
MK2 is a multi-domain protein consisting of an N-terminal proline-rich domain, a catalytic domain, an autoinhibitory domain and at the C-terminus a nuclear export signal (NES) and nuclear localization signal (NLS). Two isoforms of human MK2 have been characterized. One isoform consists of 400 amino acids and the other isoform 370 residues which is thought to be a splice variant missing the C-terminal NLS.
MK2 is known to be involved in many cellular processes including stress and inflammatory responses, nuclear export, gene expression regulation and cell proliferation. Indeed, MK2 regulates, by a post-transcriptional mechanism, biosynthesis of tumor necrosis factor α (TNFα) that is overproduced in inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease. See Natesan et al., J. Med. Chem. 2012, 55, 2035-2047.
Inhibition of Hsp27 phosphorylation occurs by inhibiting the formation of the p38 kinase-MK2-Hsp27 signaling complex. Phosphorylation of Hsp27 is the penultimate event in a complex signaling cascade that occurs in response to extracellular stimuli. See Zheng et al., The Journal of Biological Chemistry, vol. 281, no. 48, 37215-37226, Dec. 1, 2006. Hsp27 usually exists as oligomers and plays a role in regulation of many cellular functions such as inhibition of the death receptor-mediated apoptosis, promotion of proper refolding of denatured proteins by acting as a molecular chaperone, and regulation of cytoskeleton. The presence of MK2 is a necessary condition for the formation of p38 kinase-MK2-Hsp27 signaling complex in cells. See Zheng et al., The Journal of Biological Chemistry, vol. 281, no. 48, 37215-37226, Dec. 1, 2006.
Evidence suggests that many signaling proteins form multimeric complexes. See Zheng et al., The Journal of Biological Chemistry, vol. 281, no. 48, 37215-37226, Dec. 1, 2006. One such complex is the Hsp27/Akt (a serine/threonine kinase) dimer, which forms in the cytoplasm of a cell. Another complex is formed between MK2 and p38. See Ben-Levy et al., Current Biology 1998, 8:1049-1057; Natesan et al., J. Med. Chem. 2012, 55, 2035-2047; Zheng et al., The Journal of Biological Chemistry, vol. 281, no. 48, 37215-37226, Dec. 1, 2006.
In unstimulated conditions, inactive p38 and unphosphorylated MK2 form such dimer in the nucleus of a cell. Upon activation, p38 phosphorylates MK2, thereby inducing a conformational change of the autoinhibitory domain of MK2 and exposing the active site for substrate binding. Once MK2 is phosphorylated, the p38-MK2 dimer is translocated to the cytoplasm, where it forms a quaternary complex with the Hsp27-Akt dimer. See Zheng et al., The Journal of Biological Chemistry, vol. 281, no. 48, 37215-37226, Dec. 1, 2006. Hsp27 is then phosphorylated by MK2, resulting in degradation of the quaternary complex and the release of p-Hsp27 monomers and dimers. Because inhibition of MK2 blocks phosphorylation of Hsp27, without wishing to be bound by theory, it is believed that inhibition of MK2 prevents degradation of the p38-MK2-Akt-Hsp27 quaternary complex, thereby altering downstream effects. Consequent to the inhibition of quaternary complex degradation, the amount of quaternary complex would thereby increase. Moreover, the equilibrium of p38 and MK2 between the cytoplasm and nucleus would be shifted towards the cytoplasm.
Interestingly, transport of the MK2/p38 complex out of the nucleus does not require catalytically active MK2, as the active site mutant, Asp207Ala, is still transported to the cytoplasm. Phosphorylation of human MK2 by p38 on residues T222, S272 and T334 is thought to activate the enzyme by inducing a conformational change of the autoinhibitory domain thus exposing the active site for substrate binding. Mutations of two autoinhibitory domain residues W332A and K326E in murine MK2 demonstrate an increase in basal activity and a C-terminal deletion of the autoinhibitory domain renders the enzyme constitutively active, providing additional evidence to the role of this domain in inhibition of MK2 activity.
