The present invention relates to compounds useful as inhibitors of ERK kinases, for example one or both of ERK1 and ERK2 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.).
The processes involved in tumor growth, progression, and metastasis are mediated by signaling pathways that are activated in cancer cells. The ERK pathway plays a central role in regulating mammalian cell growth by relaying extracellular signals from ligand-bound cell surface tyrosine kinase receptors such as erbB family, PDGF, FGF, and VEGF receptor tyrosine kinase. Activation of the ERK pathway is via a cascade of phosphorylation events that begins with activation of Ras. Activation of Ras leads to the recruitment and activation of Raf, a serine-threonine kinase. Activated Raf then phosphorylates and activates MEK1/2, which then phosphorylates and activates one or both of ERK1 and ERK2. When activated, one or both of ERK1 and ERK2 phosphorylates several downstream targets involved in a multitude of cellular events including cytoskeletal changes and transcriptional activation. The ERK/MAPK pathway is one of the most important for cell proliferation, and it is believed that the ERK/MAPK pathway is frequently activated in many tumors. Ras genes, which are upstream of one or both of ERK1 and ERK2, are mutated in several cancers including colorectal, melanoma, breast and pancreatic tumors. The high Ras activity is accompanied by elevated ERK activity in many human tumors. In addition, mutations of BRAF, a serine-threonine kinase of the Raf family, are associated with increased kinase activity. Mutations in BRAF have been identified in melanomas (60%), thyroid cancers (greater than 40%) and colorectal cancers.
Many diseases are associated with abnormal cellular responses triggered by protein kinase-mediated events as described above. 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.
Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and —N+(C1-4alkyl)4 salts.

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, lower alkyl 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. Additionally, unless otherwise stated, structures depicted herein are also meant to include compounds that differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures including the replacement of hydrogen by deuterium or tritium, or the replacement of a carbon by a 13C- or 14C-enriched carbon are within the scope of this invention. Such compounds are useful, for example, as analytical tools, as probes in biological assays, or as therapeutic agents in accordance with the present invention. In certain embodiments, a warhead moiety, R1, of a provided compound comprises one or more deuterium atoms.
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 a 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 acting as 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.
One of ordinary skill in the art will recognize that certain reactive functional groups can act as “warheads.” As used herein, the term “warhead” or “warhead group” refers to a functional group present on a compound of the present invention wherein that functional group is capable of covalently binding to an amino acid residue (such as cysteine, lysine, histidine, or other residues capable of being covalently modified) present in the binding pocket of the target protein, thereby irreversibly inhibiting the protein. It will be appreciated that the -L-Y group, as defined and described herein, provides such warhead groups for covalently, and irreversibly, inhibiting the protein. In certain instances, a “pro-warhead group” is used in place of a warhead group. Such a pro-warhead group converts to a warhead group in vivo or in vitro.
As used herein, the term “inhibitor” is defined as a compound that binds to and/or inhibits a kinase with measurable affinity. In certain embodiments, an inhibitor has an IC50 and/or binding constant of less about 50 μM, less than about 1 μM, less than about 500 nM, less than about 100 nM, less than about 10 nM, or less than about 1 nM.
The terms “measurable affinity” and “measurably inhibit,” as used herein, means a measurable change in a kinase activity between a sample comprising a compound of the present invention, or composition thereof, and a kinase, and an equivalent sample comprising a kinase, in the absence of said compound, or composition thereof.
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.
As described herein, the present invention provides irreversible inhibitors of one or both of ERK1 and ERK2 kinase. The compounds of the invention comprise a warhead group, designated as R1, as described herein. Without wishing to be bound by any particular theory, it is believed that such R1 groups, i.e. warhead groups, are particularly suitable for covalently binding to a key cysteine residue in the binding domain of one or both of ERK1 and ERK2 kinase. One of ordinary skill in the art will appreciate that one or both of ERK1 and ERK2 kinase, and mutants thereof, have a cysteine residue in the binding domain. Without wishing to be bound by any particular theory, it is believed that proximity of a warhead group to the cysteine of interest facilitates covalent modification of that cysteine by the warhead group.
The cysteine residues of interest can also be described by an identifying portion of the Target's amino acid sequence which includes the cysteine of interest. Thus, in certain embodiments, Cys183 of ERK1 is characterized in that Cys183 is the cysteine embedded in the amino acid sequence of ERK1.
Cys166 of ERK2 is characterized in that Cys166 is the cysteine embedded in the amino acid sequence of ERK2.
In some embodiments, compounds of the present invention include a warhead group characterized in that provided compounds covalently modify one or more of Cys 183 of ERK1 or Cys166 of ERK2.
In certain embodiments, compounds of the present invention include a warhead group characterized in that provided compounds bind to a target of Cys183 of ERK1 or Cys166 of ERK2, thereby irreversibly inhibiting the kinase.
Thus, in some embodiments, the R1 warhead group is characterized in that the -L-Y moiety, as defined and described below, is capable of covalently binding to a cysteine residue thereby irreversibly inhibiting the enzyme. In some embodiments, the cysteine residue is Cys183 of ERK1. In some embodiments, the cysteine residue is Cys166 of ERK2. In some embodiments, it is both Cys183 of ERK1 and Cys166 of ERK2. One of ordinary skill in the art will recognize that a variety of warhead groups, as defined herein, are suitable for such covalent bonding. Such R1 groups include, but are not limited to, those described herein and depicted infra.

or a pharmaceutically acceptable salt thereof, wherein:
R1 is a warhead group, wherein when Ring A is a monocyclic ring, then R1 is attached to an atom adjacent to where W is attached;

Uses of Compounds and Pharmaceutically Acceptable Compositions
Compounds and compositions described herein are generally useful for the inhibition of kinase activity of one or more enzymes.
Examples of kinases that are inhibited by the compounds and compositions described herein and against which the methods described herein are useful include one or both of ERK1 and ERK2, or a mutant thereof.
The activity of a compound utilized in this invention as an inhibitor of one or both of an ERK1 and ERK2 kinase, or a mutant thereof, may be assayed in vitro, in vivo or in a cell line. In vitro assays include assays that determine inhibition of either the phosphorylation activity and/or the subsequent functional consequences, or ATPase activity of one or both of activated ERK1 and ERK2 kinase, or a mutant thereof. Alternate in vitro assays quantitate the ability of the test compound to bind to one or both of ERK1 and ERK2. Test compound binding may be measured by radiolabeling the test compound prior to binding, isolating one or both of the compound/ERK1 complex and the compound/ERK2 complex, and determining the amount of radiolabel bound. Alternatively, test compound binding may be determined by running a competition experiment where test compounds are incubated with one or both of ERK1 and ERK2 kinase bound to known radioligands. Detailed conditions for assaying a compound utilized in this invention as an inhibitor of one or both of ERK1 and ERK2, or a mutant thereof, are also set forth in the Examples below.
Without wishing to be bound by any particular theory, it is believed that a provided compound comprising a warhead moiety is more effective at inhibiting one or both of ERK1 and ERK2, or a mutant thereof, as compared to a corresponding compound wherein the R1 moiety of any of the formulae herein is instead a non-warhead group or is completely absent (i.e., is hydrogen). For example, a compound of any of the formulae herein is more effective at inhibition of one or both of ERK1 and ERK2, or a mutant thereof, as compared to a corresponding compound wherein the R1 moiety of any of the formulae herein is instead a non-warhead moiety or is absent.
A provided compound comprising a warhead moiety, as disclosed above, is more potent with respect to an IC50 against one or both of ERK1 and ERK2, or a mutant thereof, than a corresponding compound wherein the R1 moiety of any of the formulae herein is instead a non-warhead moiety or is absent. Such comparative potency can be determined by standard time-dependent assay methods, such as those described in detail in the Examples section, infra. In certain embodiments, a compound of any of the formulae herein is measurably more potent than a corresponding compound of any of the formulae herein wherein the R1 moiety is a non-warhead moiety or is absent. In some embodiments, a compound of any of the formulae herein is measurably more potent, wherein such potency is observed after about 1 minute, about 2 minutes, about 5 minutes, about 10 minutes, about 20 minutes, about 30 minutes, about 1 hour, about 2 hours, about 3 hours, about 4 hours, about 8 hours, about 12 hours, about 16 hours, about 24 hours, or about 48 hours, than a corresponding compound of any of the formulae herein wherein the R1 moiety of formula is a non-warhead moiety or is absent. In some embodiments, a compound of any of the formulae herein is any of about 1.5 times, about 2 times, about 5 times, about 10 times, about 20 times, about 25 times, about 50 times, about 100 times, or even about 1000 times more potent than a corresponding compound of any of the formulae herein wherein the R1 moiety is a non-warhead moiety or is absent.
ERK1 and ERK2 Kinase
As described generally above, the compounds of the invention are useful as inhibitors of ERK protein kinases. ERK is one of the key components in the RAS-RAF-MEK-ERK MAPK pathway. As a downstream target, ERK inhibitors are believed to be able to overcome drug resistance from K-RAS and B-RAF mutations, as well as toxicity from RAF and MEK inhibitors. Kinase selectivity was achieved through silencing the selective Cys in a combination of the interactions between the covalent inhibitors of the invention and unique amino acids in the ATP binding pocket. Targeting the selective Cys provides for prolonged pharmacodynamics in silencing ERK activity, as well as potential lower doses in cancer treatment, compared to reversible inhibitors.
In one embodiment, the compounds and compositions of the invention are inhibitors of one or both of ERK1 and ERK2 protein kinases and thus, without wishing to be bound by any particular theory, the compounds and compositions are particularly useful for treating or lessening the severity of a disease, condition, or disorder where activation of one or both of ERK1 and ERK2 protein kinases is implicated in the disease, condition, or disorder. When activation of one or both of ERK1 and ERK2 protein kinases is implicated in a particular disease, condition, or disorder, the disease, condition, or disorder may also be referred to as “a disease, disorder, or condition mediated by one or both of ERK1 and ERK2”, or alternatively as an “ERK1- or ERK2-mediated disease”, condition, or disease symptom. Accordingly, in another aspect, the present invention provides a method for treating or lessening the severity of a disease, condition, or disorder where activation of one or both of ERK1 and ERK2 protein kinases is implicated in said disease, condition, or disorder.
The activity of a compound utilized in this invention as an inhibitor of one or both of ERK1 and ERK2 protein kinases may be assayed in vitro, in vivo or in a cell line. In vitro assays include assays that determine inhibition of either the phosphorylation activity or ATPase activity of one or both of activated ERK1 and ERK2 protein kinases. Alternate in vitro assays quantitate the ability of the test compound to bind to one or both of ERK1 and ERK2 protein kinases. Test compound binding may be measured by radiolabelling the test compound prior to binding, isolating one or both of the test compound/ERK1 complex and test compound/ERK2 complex, and determining the amount of radiolabel bound. Alternatively, test compound binding may be determined by running a competition experiment where new test compounds are incubated with one or both of ERK1 and ERK2 protein kinases bound to known radioligands. Detailed conditions for assaying a compound utilized in this invention as an inhibitor of one or both of ERK1 and ERK2, or a mutant thereof, are also set forth in the Examples below.
The term “measurably inhibit”, as used herein means a measurable change in one or both of ERK1 and ERK2 protein kinase activity between a sample comprising said composition, and one or both of an ERK1 and ERK2 protein kinase and an equivalent sample comprising one or both of ERK1 and ERK2 protein kinase in the absence of said composition. Such measurements of protein kinase activity are known to one of ordinary skill in the art and include those methods set forth herein below.

In certain embodiments, the invention provides a method for overcoming drug resistance to Raf and Mek inhibitors, comprising the step of administering to said patient an inhibitor compound of one or both of ERK1 and ERK2.
As used herein, the term “clinical drug resistance” refers to the loss of susceptibility of a drug target to drug treatment as a consequence of mutations in the drug target.
As used herein, the term “resistance” refers to changes in the wild-type nucleic acid sequence coding a target protein, and/or the protein sequence of the target, which changes decrease or abolish the inhibitory effect of the inhibitor on the target protein.
As used herein, the terms “treatment,” “treat,” and “treating” refer to reversing, alleviating, delaying the onset of, or inhibiting the progress of a disease or disorder, or one or more symptoms thereof, as described herein. In some embodiments, treatment is administered after one or more symptoms have developed. In other embodiments, treatment is administered in the absence of symptoms. For example, treatment is 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 is also continued after symptoms have resolved, for example to prevent or delay their recurrence.
The compounds and compositions, according to the 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 above. 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 dosage unit form for ease of administration and uniformity of dosage. The expression “dosage unit form” as used herein refers to a physically discrete unit of agent appropriate for the patient to be treated. It will be understood, however, that the total daily usage of the 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 patient or organism will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed, and like factors well known in the medical arts.
Pharmaceutically acceptable compositions of this invention can be administered to humans and other animals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), bucally, as an oral or nasal spray, or the like, depending on the severity of the infection being treated. In certain embodiments, the compounds of the invention are administered orally or parenterally at dosage levels of about 0.01 mg/kg to about 50 mg/kg and preferably from about 1 mg/kg to about 25 mg/kg, of subject body weight per day, one or more times a day, to obtain the desired therapeutic effect.
Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.
Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic 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, U.S.P. 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 can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.
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.
Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound.
Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.
Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polethylene glycols and the like.
The active compounds can also be in micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art. In such solid dosage forms the active compound may be admixed with at least one inert diluent such as sucrose, lactose or starch. Such dosage forms may also comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes.
Dosage forms for topical or transdermal administration of a compound of this invention include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. The active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required. Ophthalmic formulation, ear drops, and eye drops are also contemplated as being within the scope of this invention. Additionally, the present invention contemplates the use of transdermal patches, which have the added advantage of providing controlled delivery of a compound to the body. Such dosage forms can be made by dissolving or dispensing the compound in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate can be controlled by either providing a rate controlling membrane or by dispersing the compound in a polymer matrix or gel.

In certain aspects, a compound of the present invention is tethered to a detectable moiety to form a probe compound. In one aspect, a probe compound of the invention comprises an irreversible protein kinase inhibitor of any formulae as described herein, a detectable moiety, and a tethering moiety that attaches the inhibitor to the detectable moiety.
In some embodiments, such probe compounds of the present invention comprise a provided compound of any formulae as described herein, tethered to a detectable moiety, RP, by a bivalent tethering moiety, -TP-. In certain embodiments, a provided probe compound is selected from any of following formulae:
wherein each of Ring A, Ring B, R1, R2, R3, Ry, W, m and p, with respect to the formulae above, is as defined and described in embodiments herein, TP is a bivalent tethering moiety; and RP is a detectable moiety. In some embodiments, when Ring A is a five or six member ring, then R1 is attached to an atom adjacent to where W, N, or O is attached.
In some embodiments, RP is a detectable moiety selected from a primary label or a secondary label. In certain embodiments, RP is a detectable moiety selected from a fluorescent label (e.g., a fluorescent dye or a fluorophore), a mass-tag, a chemiluminescent group, a chromophore, an electron dense group, or an energy transfer agent.
As used herein, the term “detectable moiety” is used interchangeably with the term “label” and “reporter” and relates to any moiety capable of being detected, e.g., primary labels and secondary labels. A presence of a detectable moiety can be measured using methods for quantifying (in absolute, approximate or relative terms) the detectable moiety in a system under study. In some embodiments, such methods are well known to one of ordinary skill in the art and include any methods that quantify a reporter moiety (e.g., a label, a dye, a photocrosslinker, a cytotoxic compound, a drug, an affinity label, a photoaffinity label, a reactive compound, an antibody or antibody fragment, a biomaterial, a nanoparticle, a spin label, a fluorophore, a metal-containing moiety, a radioactive moiety, quantum dot(s), a novel functional group, a group that covalently or noncovalently interacts with other molecules, a photocaged moiety, an actinic radiation excitable moiety, a ligand, a photoisomerizable moiety, biotin, a biotin analog (e.g., biotin sulfoxide), a moiety incorporating a heavy atom, a chemically cleavable group, a photocleavable group, a redox-active agent, an isotopically labeled moiety, a biophysical probe, a phosphorescent group, a chemiluminescent group, an electron dense group, a magnetic group, an intercalating group, a chromophore, an energy transfer agent, a biologically active agent, a detectable label, and any combination of the above).

Detectable moities are analyzed by methods. Exemplary methods are fluorescence, positron emission tomography, SPECT medical imaging, chemiluminescence, electron-spin resonance, ultraviolet/visible absorbance spectroscopy, mass spectrometry, nuclear magnetic resonance, magnetic resonance, flow cytometry, autoradiography, scintillation counting, phosphoimaging, and electrochemical methods.
The term “secondary label” as used herein refers to moieties such as biotin and various protein antigens that require the presence of a second intermediate for production of a detectable signal. For biotin, the secondary intermediate includes streptavidin-enzyme conjugates. For antigen labels, secondary intermediates include antibody-enzyme conjugates. Some fluorescent groups act as secondary labels because they transfer energy to another group in the process of nonradiative fluorescent resonance energy transfer (FRET), and the second group produces the detected signal.

Described below are in vitro assays used to measure the biological activity of provided compounds as selective inhibitors of one or both of ERK 1 and ERK 2.
Intact protein: Erk1 from Millipore (Cat. No. 14-439) was incubated for 60 min. at room temperature with a 10-fold excess of test compound to protein. 4 μL aliquots of the resulting mixture were diluted with 15 μL of 0.2% TFA prior to micro C4 ZipTipping directly onto the MALDI target using sinapinic acid as the desorption matrix (10 mg/ml in 0.1% TFA:Acetonitrile 50:50, v/v). The centroid mass of the target protein in the control sample was compared with the centroid mass of the target protein incubated with compound. A shift in the centroid mass of the treated protein compared to the untreated protein was divided by the molecular weight of the compound. This number corresponds to the percentage of modified protein after one hour incubation. Results from this assay are reported in Table A under the column “ERK1 Mass Mod (%).”
The protocol below describes continuous-read kinase assays to measure potency of compounds against activated ERK1 enzyme. The mechanics of the assay platform are best described by the vendor (Invitrogen, Carlsbad, Calif.) on their website at the following URL: invitrogen.com/site/us/en/home.html.
Briefly, a 1.25× stock of ERK1 enzyme (14-439-K) from Millipore (Billerica, Mass.), 5×ATP (AS001A) and ST17-Sox conjugated peptide substrate (KNZ1171C) were prepared in 1× kinase reaction buffer consisting of 20 mM Tris, pH 7.5, 5 mM MgCl2, 1 mM EGTA, 5 mM β-glycerophosphate, 5% glycerol (10× stock, KB002A) and 0.2 mM DTT. 10 μL of ATP/ST17-sox peptide substrate mix was combined with 0.5 μL volume of 100% DMSO and serially diluted compounds were prepared in 100% DMSO in a Corning (#3574) 384-well, white, non-binding surface microtiter plate (Corning, N.Y.). Kinase reactions were started with the addition of 40 μL of ERK1 solution and monitored every 71 seconds for 30-240 minutes at λex360/λem485 in a Synergy plate reader from BioTek (Winooski, Vt.). At the conclusion of each assay, progress curves from each well were examined for linear reaction kinetics and fit statistics (R2, 95% confidence interval, absolute sum of squares). Initial velocity (0 minutes to ˜30+ minutes) from each reaction was determined from the slope of a plot of relative fluorescence units vs time (minutes or seconds) and then plotted against inhibitor concentration to estimate AppIC50 from log [Inhibitor] vs Response, Variable Slope model in GraphPad Prism from GraphPad Software (San Diego, Calif.).
[Reagent] used in optimized protocol:
[ERK1]=4 nM, [ATP]=50 μM, [ST17-Sox]=10 μM (ATP appKM 48 μM)
The results of this assay show the degree of inhibition of ERK activity, which is a direct measurement of inhibition of ERK activity. Results from this assay are reported in Table A under the column “ERK1 Omnia WT ATP KM IC50 (nM).”
pRSK MSD Assay
The protocol below describes an assay to measure the kinase activity of ERK1/2 to phosphorylate a substrate, p90RSK, in the presence or absence of a test compound. This experiment was conducted using a Mesoscale Discovery plate. The day before the assay, HT29 cells were split and plated at 50,000 cells/well in complete growth media. After allowing cells to adhere, the media was removed and replaced with media containing 0.1% FBS and incubated overnight. Blank MSD plates (Mesoscale Discovery, Cat # L15XA3) were coated with 25 μl/well RSK capture antibody (BD Biosciences, Cat. #610226) and incubated at 4° C. overnight, then blocked with 150 μl of 3% BSA solution. The next day, the media from the cell culture plate was removed and replaced with 100 μl of media containing a test compound and incubated for 120 minutes at 37° C. The media was removed and replaced with 55 μl per well of lysis buffer with protease inhibitors (Roche Biosciences, Cat. #11836170001) and phosphatase inhibitors (Sigma-Aldrich, Cat. # P-0044 and P-5726), followed by incubation at 4° C. for 30 minutes. 50 μl of lysate was transferred to a blocked MSD plate, followed by incubation at room temperature for 2 hours under constant shaking. The plate was washed 3 times with MSD wash buffer (Mesoscale Discovery, Cat. # R617TX), and 25 μl/well phospho-RSK (pRSK) detection antibody (Cell Signaling Technology, Cat. #9335) was added with Sulfo-tagged detection antibody (Mesoscale Discovery, Cat. # R32AB-1) diluted in 1% BSA in MSD wash buffer. This mixture was incubated for 1 hour at room temperature under constant shaking. The plate was washed 3 times, and 150 μl 1×MSD read buffer was added, followed by signal detection in an MSD plate reader. Curve fitting analysis was done with variable slope in GraphPad software to generate EC50 based on DMSO control (untreated) being 100% pRSK signal and maximum inhibition with a reference compound provided by the manufacturer as a positive control. Results from this assay, showing EC50 (i.e., the concentration at which a test compound inhibits phosphorylation of RSK by 50%) are reported in Table A under the column “ERK1/ERK2 PRSK MSD HT29 EC50 (nM).”
Measurment of Erk Occupancy with Biotinylated Covalent Probe
This experiment measured occupancy of the ERK1/ERK2 target by compounds according to the invention. This experiment was conducted using the Mesoscale Discovery test kit (Cat. # N45107B). One day before the assay, cells were split and added at 50,000 cells per well to a flat-bottom 96 well plate in 200 μl of growth medium. The next day, the medium was discarded, 100 μl medium containing test compound was added, and the plate was incubated at 37° C. for 120 minutes. The plate was rinsed once with PBS, and 50 μl lysis buffer with test compound was added. The plate was incubated at 4° C. for 30 min, and 30 μl of lysate was transferred to a plate to capture total and phosphor-Erk. Biotinylated probe 1-299 was diluted in lysis buffer and added to each well to a final concentration of 0.2 μM. The plate was incubated for 2 hr under constant shaking at room temperature. The plate was washed 3 times with MSD wash buffer. To detect the biotinylated probe bonding, tagged streptavidin was added (Mesoscale Discovery, Cat. # R32AD-1) at 1 μg/ml, 25 μl/well, followed by a 60 min incubation under shaking. The plate was washed 3 times, 150 μl MSD Read Buffer (Mesoscale Discovery, Cat. R61TX) was added and the plate was read in a plate reader manufactured by MSD. Percent occupancy by test compound at Erk was calculated by comparing the chemiluminescence readings from treated cells as compared to the chemiluminescence readings in untreated controls (which are defined as 100% probe bonding or 0% test compound occupancy). The amount of covalent probe signal divided by the amount of ERK signal for samples with no test compound treatment represents the maximum probe signal (MPS). In samples treated with test compound prior to covalent probe, the ratio of probe signal to ERK signal (the test probe signal, TPS) was reduced by the degree of target occupancy by the test compound which blocks covalent probe binding. The difference between the MPS and the TPS, divided by the MPS gave the target occupancy by the test compound. This ratio was then expressed as a percent occupancy. Results from this assay are provided in Table A below under the column “Occupancy EC50 (nM) HT-29.”
This example shows the extended activity of compounds according to the invention. One day before the assay, the cells were split and added at 50,000 cells per well in flat-bottom 96 well plate in 200 μl of growth media. The next day, the medium was discarded, 100 μl medium containing test compounds was added, and the plate was incubated at 37° C. for 120 minutes. The medium was discarded, and the cells were rinsed 3 times with PBS followed by addition of 200 μl of fresh grow medium. The plate was returned to a 37° C. incubator, and separate cell lysates were made using MSD lysis buffer after 0.25, 0.5, 1, 2, 4, 6, 8 and 18 or 24 hours. Thereafter, pRSK was measured as described above in the section entitled pRSK MSD Assay. The data is presented in Table A under the column titled “p-RSK inhibition at 6 hr (%).”
The following protocol used an HT-29 cell line, which cell line is a model for colorectal adenocarcinoma. HT-29 cells were split and 3000 cells in 100 μl of growth medium were added per well of a flat-bottom 96-well plate. A two-fold test compound solution in serum-free RPM1640 was made, starting at 5,000 nM. Then, 3-fold serial dilutions were made across the plate from well 1 to well 11. Well 12, the last well in a row on the plate, was left as untreated control. 100 μl compound solutions were then transferred to the wells, so the total volume of media was 200 μl per well. Plates were returned to a 37° C. incubator, and the cells were cultured for 72 hours. To measure cell proliferation after 72 hours, media was discarded from the plates, 50 μl/well of fresh medium was added, and 50 μl CellTiterGlo solution was added (Promega Cat#G7573). The plate was covered with a dark lid and incubated for 10 min. A white sealing tape was applied to the bottom of the plate, and the plate was read in a luminescence plate reader. In order to calculate GI50 (the proliferation of HT29 was inhibited by 50%) a standard curve was established to measure luminescence readings at certain cell densities by the following method. A 2-fold serial dilution was used to generate 8 cell densities from 50,000-390 cells per well in 50 μl media. 50 μl CellTiterGlo was added per well, and the plate was read in a luminescence plate reader after 10 min. The reading was plotted vs. cell number to generate a standard curve and the equation of the curve fit. The compound-treated sample luminescence readings were converted to cell numbers using the curve-fit equation. The percent of inhibition, using untreated control as 100% growth, was then calculated. GI50 was then calculated by GraphPad Prism. Accordingly, this assay provides the dose at which 50% inhibition of cell growth was achieved and this data is shown in Table A, in the column entitled “HT-29 GI50 (nM).”
The following protocol used a HCT116 cell line, which cell line is a model for colorectal carcinoma. HCT116 cells were split and 3000 cells in 100 μl of growth medium were added per well of a flat-bottom 96-well plate. A two-fold test compound solution in serum-free RPM1640 was made, starting at 5,000 nM. Then, 3-fold serial dilutions were made across the plate from well 1 to well 11. Well 12, the last well in a row on the plate, was left as untreated control. 100 μl compound solutions were then transferred to the wells, so the total volume of media was 200 μl per well. Plates were returned to a 37° C. incubator, and the cells were cultured for 72 hours. To measure cell proliferation after 72 hours, media was discarded from the plates, 50 μl/well of fresh medium was added, and 50 μl CellTiterGlo solution was added (Promega Cat#G7573). The plate was covered with a dark lid and incubated for 10 min. A white sealing tape was applied to the bottom of the plate, and the plate was read in a luminescence plate reader. In order to calculate GI50 (the concentration at which 50% of growth is inhibited) a standard curve was established to measure luminescence readings at specific cell densities by the following method: a 2-fold serial dilution was used to generate 8 cell densities from 50,000-390 cells per well in 50 n1 media. 50 μl CellTiterGlo was added per well, and the plate was read in a luminescence plate reader after 10 min. The reading was plotted vs. cell number to generate a standard curve and the equation of the curve fit. The compound-treated sample luminescence readings were converted to cell numbers using the curve-fit equation. The percent of inhibition, using untreated control as 100% growth, was then calculated. GI50 was then calculated by GraphPad Prism. Accordingly, this assay provides the dose at which 50% inhibition of cell growth was achieved and this data is shown in Table A, in the column entitled “HCT116 GI50 (nM).”
The following protocol used an A375 cell line, which cell line is a model for malignant melanoma. A375 cells were split and 3000 cells in 100 n1 of growth medium were added per well of a flat-bottom 96-well plate. A two-fold test compound solution in serum-free DMEM was made, starting at 5,000 nM. Then, 3-fold serial dilutions were made across the plate from well 1 to well 11. Well 12, the last well in a row on the plate, was left as untreated control. 100 μl compound solutions were then transferred to the wells, so the total volume of media was 200 μl per well. Plates were returned to a 37° C. incubator, and the cells were cultured for 72 hours. To measure cell proliferation after 72 hours, media was discarded from the plates, 50 μl/well of fresh medium was added, and 50 μl CellTiterGlo solution was added (Promega Cat#G7573). The plate was covered with a dark lid and incubated for 10 min. A white sealing tape was applied to the bottom of the plate, and the plate was read in a luminescence plate reader.

The reading was plotted vs. cell number to generate a standard curve and the equation of the curve fit. The compound-treated sample luminescence readings were converted to cell numbers using the curve-fit equation. The percent of inhibition, using untreated control as 100% growth, was then calculated. GI50 was then calculated by GraphPad Prism. Accordingly, this assay provides the dose at which 50% inhibition of cell growth was achieved and this data is shown in Table A, in the column entitled “A375 GI50 (nM).”

Compound stock solutions of 10 mM in DMSO were prepared. 1000× dilutions were then prepared in DMSO. 1 uL of DMSO solution was then transferred to 1 ml DMEM/0.1% FBS in a deep well plate. Cell plate media was discarded, followed by addition of 100 uL of the compound-containing media. The preparation was incubated at 37° C. for 2 hrs.
Cell lysates were prepared as described below.
pRSK or Total RSK MSD Assay
MSD plates: Blank MSD plates were coated with 30 uL capture antibody (BD 610226) at a final concentration of 1 ug/mL in PBS. Both pRSK and total RSK MSD assays used the same capture antibody at the same concentration. Antibody stock concentration was 250 ug/mL. Once antibody solution was added to the MSD plate, the sides were tapped to be certain it was coated completely (visual inspection). It was then covered and placed at 4° C. overnight on a level surface.
Block MSD Plate: The coating antibody was removed and the plate was washed on a plate washer in MSD wash buffer. The last bit of wash solution was tapped out and 150 uL/well of 3% BSA in MSD wash buffer was added in. The preparation was placed on a shaker at room temperature for at least an hour.
Add samples: Media was removed from compound-treated cells and replaced with 55 uL/well MSD cell lysis buffer containing protease and phosphotase I & II inhibitors. The preparation was incubated on a shaker in a cold room for 30-45 min. The blocked MSD plate was washed a on plate washer, tapping out the last bit of wash solution, followed by addition of 50 uL (of the 55 ul) cell lysate in a well-well transfer. The preparation was covered and incubated on a shaker at room temp for 2 hours. The lysate was removed, washed on a plate washer 3 times, and the last bit of wash buffer was tapped out and replace with 25 uL/well detection antibody (described below).

For total RSK detection, a total RSK antibody stock of 200 ug/mL was prepared as follows: 1 ug/mL total RSK (Santa Cruz sc-231G) antibody+1:750 anti-goat SulfoTag (from MSD, R32AG-1) in 1% BSA in MSD wash buffer.
The plate was incubated for 1 hr at room temperature on a shaker, followed by three washings. The last bit of wash buffer was tapped out. 150 uL/well 1×MSD Read buffer was added and the plate was then analyzed. Curve fitting analysis was done with variable slope in Graph Pad software to generate EC50 based on DMSO control (untreated) being 100% pRSK signal and maximum inhibition with a reference compound provided by the manufacturer as a positive control. Results from this assay, showing EC50 (i.e., the concentration at which a test compound inhibits phosphorylation of RSK by 50%) are reported in Table A under the column “ERK1/ERK2 PRSK MSD A375 EC50 (nM).”
