Protein kinase C (“PKC”) is a key enzyme in signal transduction involved in a variety of cellular functions, including cell growth, regulation of gene expression, and ion channel activity. The PKC family of isozymes includes at least 11 different protein kinases that can be divided into at least three subfamilies based on their homology and sensitivity to activators. Each isozyme includes a number of homologous (“conserved” or “C”) domains interspersed with isozyme-unique (“variable” or “V”) domains. Members of the “classical” or “cPKC” subfamily, PKC α, βi, βii and γ, contain four homologous domains (C1, C2, C3 and C4) and require calcium, phosphatidylserine, and diacylglycerol or phorbol esters for activation. Members of the “novel” or “nPKC” subfamily, PKC δ, ε, η and θ, lack the C2 homologous domain and do not require calcium for activation. Finally, members of the “atypical” or “αPKC” subfamily, PKC ζ and lack both the C2 and one-half of the C1 homologous domains and are insensitive to diacylglycerol, phorbol esters and calcium.

In such cases, the maximum number of such substitutions is three. For example, serial substitutions of substituted aryl groups specifically contemplated herein are limited to substituted aryl-(substituted aryl)-substituted aryl.
Unless indicated otherwise, the nomenclature of substituents that are not explicitly defined herein are arrived at by naming the terminal portion of the functionality followed by the adjacent functionality toward the point of attachment. For example, the substituent “arylalkyloxycarbonyl” refers to the group (aryl)-(alkyl)-O—C(O)—.
As to any of the groups disclosed herein which contain one or more substituents, it is understood, of course, that such groups do not contain any substitution or substitution patterns which are sterically impractical and/or synthetically non-feasible. In addition, the subject compounds include all stereochemical isomers arising from the substitution of these compounds.
The term “pharmaceutically acceptable salt” means a salt which is acceptable for administration to a patient, such as a mammal (salts with counterions having acceptable mammalian safety for a given dosage regime). Such salts can be derived from pharmaceutically acceptable inorganic or organic bases and from pharmaceutically acceptable inorganic or organic acids. “Pharmaceutically acceptable salt” refers to pharmaceutically acceptable salts of a compound, which salts are derived from a variety of organic and inorganic counter ions well known in the art and include, by way of example only, sodium, potassium, calcium, magnesium, ammonium, tetraalkylammonium, and the like; and when the molecule contains a basic functionality, salts of organic or inorganic acids, such as hydrochloride, hydrobromide, formate, tartrate, besylate, mesylate, acetate, maleate, oxalate, and the like.
The term “salt thereof” means a compound formed when a proton of an acid is replaced by a cation, such as a metal cation or an organic cation and the like. Where applicable, the salt is a pharmaceutically acceptable salt, although this is not required for salts of intermediate compounds that are not intended for administration to a patient. By way of example, salts of the present compounds include those wherein the compound is protonated by an inorganic or organic acid to form a cation, with the conjugate base of the inorganic or organic acid as the anionic component of the salt.
“Solvate” refers to a complex formed by combination of solvent molecules with molecules or ions of the solute. The solvent can be an organic compound, an inorganic compound, or a mixture of both. Some examples of solvents include, but are not limited to, methanol, N,N-dimethylformamide, tetrahydrofuran, dimethylsulfoxide, and water. When the solvent is water, the solvate formed is a hydrate.
“Stereoisomer” and “stereoisomers” refer to compounds that have same atomic connectivity but different atomic arrangement in space. Stereoisomers include cis-trans isomers, E and Z isomers, enantiomers, and diastereomers.
“Tautomer” refers to alternate forms of a molecule that differ only in electronic bonding of atoms and/or in the position of a proton, such as enol-keto and imine-enamine tautomers, or the tautomeric forms of heteroaryl groups containing a —N═C(H)—NH— ring atom arrangement, such as pyrazoles, imidazoles, benzimidazoles, triazoles, and tetrazoles. A person of ordinary skill in the art would recognize that other tautomeric ring atom arrangements are possible.
It will be appreciated that the term “or a salt or solvate or stereoisomer thereof” is intended to include all permutations of salts, solvates and stereoisomers, such as a solvate of a pharmaceutically acceptable salt of a stereoisomer of subject compound.
“Pharmaceutically effective amount” and “therapeutically effective amount” refer to an amount of a compound sufficient to treat a specified disorder or disease or one or more of its symptoms and/or to prevent the occurrence of the disease or disorder. In reference to tumorigenic proliferative disorders, a pharmaceutically or therapeutically effective amount comprises an amount sufficient to, among other things, cause the tumor to shrink or decrease the growth rate of the tumor.
“Patient” refers to human and non-human subjects, especially mammalian subjects.
The term “treating” or “treatment” as used herein means the treating or treatment of a disease or medical condition in a patient, such as a mammal (particularly a human) that includes: (a) preventing the disease or medical condition from occurring, such as, prophylactic treatment of a subject; (b) ameliorating the disease or medical condition, such as, eliminating or causing regression of the disease or medical condition in a patient; (c) suppressing the disease or medical condition, for example by, slowing or arresting the development of the disease or medical condition in a patient; or (d) alleviating a symptom of the disease or medical condition in a patient.
The following substituents and values are intended to provide representative examples of various aspects and embodiments. These representative values are intended to further define and illustrate such aspects and embodiments and are not intended to exclude other embodiments or to limit the scope of the present disclosure. In this regard, the representation that a particular value or substituent is preferred is not intended in any way to exclude other values or substituents from the present disclosure unless specifically indicated.
These compounds may contain one or more chiral centers and therefore, the embodiments are directed to racemic mixtures; pure stereoisomers (i.e., enantiomers or diastereomers); stereoisomer-enriched mixtures and the like unless otherwise indicated. When a particular stereoisomer is shown or named herein, it will be understood by those skilled in the art that minor amounts of other stereoisomers may be present in the compositions unless otherwise indicated, provided that the desired utility of the composition as a whole is not eliminated by the presence of such other isomers.

A variety of examples of synthetic routes that can be used to synthesize the 2,4-pyrimidinediamine compounds disclosed herein are described in the schemes below. These methods can be adapted to synthesize the 2,4-pyrimidinediamine compounds and prodrugs described herein.
Synthesis of Compounds
In certain embodiments, the compounds can be synthesized from substituted or unsubstituted uracils as illustrated in Scheme 1, below:
In Scheme 1, R11, R12, R13, R14, R15, R16, Y1, Y2, and Q are as set forth hereinbefore.
According to Scheme 1, uracil A-1 is dihalogenated at the 2- and 4-positions using a standard dehydrating-halogenating agent such as POCl3 (phosphorus oxychloride) (or other standard halogenating agent) to yield 2,4 dichloropyrimidine A-2. Depending upon the substituents in pyrimidinediamine A-2, the chloride at the C4 position is more reactive towards nucleophiles than the chloride at the C2 position. This differential reactivity can be exploited by first reacting 2,4 dichloropyrimidine A-2 with one equivalent of amine A-3, yielding 4N-substituted-2-chloro-4-pyrimidineamine A-4, followed by one or more equivalents of amine A-5 to yield a 2,4-pyrimidinediamine derivative A-6.
Typically, the C4 halide is more reactive towards nucleophiles, as illustrated in the scheme. However, as will be recognized by skilled artisans, the identity of the substituent may alter this reactivity. For example, when the substituent is trifluoromethyl, a 50:50 mixture of 4N-substituted-4-pyrimidineamine A-4 and the corresponding 2N-substituted-2-pyrimidineamine is obtained. The regioselectivity of the reaction can also be controlled by adjusting the solvent and other synthetic conditions (such as temperature), as is well-known in the art.
In certain embodiments, to couple compounds with an electrophilic leaving group, such as halides or pseudohalides, and compounds with an amino group, nucleophilic aromatic substitution can be used. For example, a halogen substituent on Compound A-2 and the amino group on Compound A-3 can react. Also for example, a halogen substituent on Compound A-4 and the amino group on Compound A-5 can react. Conditions for nucleophilic aromatic substitution include the compounds reacting in a polar aprotic solvent or polar protic solvent. Suitable solvents include alcohols (such as isopropanol, methanol, ethanol), formic acid, dimethylsulfoxide, dimethylformamide, dioxane, and tetrahydrofuran. The reaction can be run at room temperature or can be heated.
In certain embodiments, to couple compounds with an electrophilic leaving group, such as halides or pseudohalides, and aryl compounds with an amino group, a coupling reaction, such as a Buchwald coupling reaction, can be used. The Buchwald coupling reaction involves palladium-catalyzed synthesis of aryl amines. Starting materials are aryl halides or pseudohalides (for example, triflates) and primary or secondary amines. Such reaction can be performed using a variety of methods well known in the art and specific examples can be had by reference to the Examples hereunder described.
A specific embodiment of Scheme 1 utilizing 5-fluorouracil (Aldrich #32, 937-1) as a starting material is illustrated in Scheme 2, below.
In Scheme 2, R11, R12, R13, R14, R15, R16, Y1, Y2, and Q are as set forth hereinbefore.
Asymmetric 2N,4N-disubstituted-5-fluoro-2,4-pyrimidinediamine A-10 can be obtained by reacting 2,4-dichloro-5-fluoropyrimidine A-8 with one equivalent of amine A-3 (to yield 2-chloro-N4-substituted-5-fluoro-4-pyrimidineamine A-9) followed by one or more equivalents of amine A-5.
In certain embodiments, chloro derivatives of the compounds can be synthesized as illustrated in Scheme 3, below:
In Scheme 3, R12, R13, R14, R15, R16, Y1, Y2, and Q are as set forth hereinbefore.
Asymmetric 2N,4N-disubstituted-5-chloro-2,4-pyrimidinediamine A-15 can be obtained by reacting 2,5-dichloropyrimidin-4-ol A-12 with one equivalent of amine A-5 (to yield N2-substituted-5-chloro-pyrimidin-4-ol A-13). The hydroxy group of Compound A-13 is converted to a chloro group to yield Compound A-14, followed by reaction with one or more equivalents of amine A-3. Conversion of the hydroxy group to the chloro group can be accomplished with a dehydrating-halogenating agent such as POCl3 (phosphorus oxychloride) (or other standard halogenating agent).

Pyrimidines, such as A-11 can be purchased from commercial sources or, alternatively, can be synthesized utilizing standard techniques. Commercially available pyrimidines that can be used as starting materials in the schemes disclosed herein include, but are not limited to, 2,4,5-trichloropyrimidine (Aldrich #652032; CAS Registry 5750-76-5).
Amino Starting Materials and Intermediates
Amines, such as A-3 and A-5 can be purchased from commercial sources or, alternatively, can be synthesized utilizing standard techniques. For example, suitable amines can be synthesized from nitro precursors using standard chemistry. See also Vogel, 1989, Practical Organic Chemistry, Addison Wesley Longman, Ltd. and John Wiley & Sons, Inc. For example, amines A-5 can be prepared as described in WO 2010/090875, WO 2010/083207, WO 2011/068898 and WO 2012/012619, the disclosures of each of which are incorporated herein by reference.
In certain embodiments, Compound A-3 can be synthesized as illustrated in Schemes 4 and 5, below.
Referring to Scheme 4, thiolactam B-2 can be prepared by conjugate addition of piperidine-2-thione B-1 to ethyl acrylate. Compound B-3 can be prepared as a single geometric isomer by reacting Compound B-2 with bromoacetonitrile in the presence of triphenylphosphine and triethylamine. Selective reduction of the ester group of Compound B-3 affords the alcohol (Compound B-4). Suitable conditions for reduction of the ester group include reaction with lithium aluminum hydride, and the like. Tosylate B-5 can be prepared under standard conditions (e.g., NaH, p-TsCl). Subsequent intramolecular mucleophilic displacement of Compound B-5 affords Compound B-6.
Compound B-6 may serve as an intermediate precursor for the diastereomeric amines (which includes Compound A-3), as shown in Scheme 5 below.
Referring to Scheme 5, intermediate Compound B-6 can be preferentially converted to the cis-hydrogenated cyanoquinolizidine B-7 by catalytic hydrogenation. Alternatively, reduction of Compound B-6 with sodium cyanoborohydride affords an excess of the trans-cyanoquinolizidine B-8. The nitrile group on Compounds B-7 and B-8 can be reduced to afford (±)-lupinamine B-9 and (±)-epilupinamine B-10, respectively. Suitable conditions for reduction of the nitrile group in Compounds B-7 and B-8 include reaction with a catalyst, such as, but not limited to, nickel-aluminum alloy, or reaction with a reducing agent, such as, but not limited to, lithium aluminum hydride, and the like. Additional details of the reactions described in Schemes 4 and 5 may be found in Michael, J. P., and Jungmann, C. M., Tetrahedron, vol. 48, no. 46, pp. 10211-20220 (1992).
The stereoisomers of Compound A-3 can be isolated by procedures known to those skilled in the art. The individual stereoisomers may be obtained, for instance, by a resolution technique or by chromatography techniques (e.g., silica gel chromatography, chiral chromatography, etc.).
Although many of the synthetic schemes discussed above do not illustrate the use of protecting groups, skilled artisans will recognize that in some instances certain substituents may include functional groups requiring protection. The exact identity of the protecting group used will depend upon, among other things, the identity of the functional group being protected and the reaction conditions used in the particular synthetic scheme, and will be apparent to those of skill in the art. Guidance for selecting protecting groups, their attachment and removal suitable for a particular application can be found, for example, in Greene & Wuts, supra.
Prodrugs as described herein can be prepared by routine modification of the above-described methods. Alternatively, such prodrugs can be prepared by reacting a suitably protected 2,4-pyrimidinediamine with a suitable progroup. Conditions for carrying out such reactions and for deprotecting the product to yield prodrugs as described herein are well-known.

In certain embodiments, the disclosed compounds are useful for the inhibition of PKC activity and the treatment of a disease or disorder that is mediated through the activity of a PKC activity. Accordingly, pharmaceutical compositions comprising at least one disclosed compound are also described herein.
A pharmaceutical composition that includes a subject compound may be administered to a patient alone, or in combination with other supplementary active agents. The pharmaceutical compositions may be manufactured using any of a variety of processes, including, but not limited to, conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping, lyophilizing, and the like. The pharmaceutical composition can take any of a variety of forms including, but not limited to, a sterile solution, suspension, emulsion, lyophilisate, tablet, pill, pellet, capsule, powder, syrup, elixir or any other dosage form suitable for administration.
A subject compound may be administered to a subject using any convenient means capable of resulting in the desired reduction in disease condition or symptom. Thus, a subject compound can be incorporated into a variety of formulations for therapeutic administration. More particularly, a subject compound can be formulated into pharmaceutical compositions by combination with appropriate pharmaceutically acceptable carriers or diluents, and may be formulated into preparations in solid, semi-solid, liquid or gaseous forms, such as tablets, capsules, powders, granules, ointments, solutions, suppositories, injections, inhalants, aerosols, and the like
Formulations for pharmaceutical compositions are described in, for example, Remington's Pharmaceutical Sciences, by E. W. Martin, Mack Publishing Co., Easton, Pa., 19th Edition, 1995, which describes examples of formulations (and components thereof) suitable for pharmaceutical delivery of disclosed compounds. Pharmaceutical compositions that include at least one of the subject compounds can be formulated for use in human or veterinary medicine. Particular formulations of a disclosed pharmaceutical composition may depend, for example, on the mode of administration and/or on the location of the subject to be treated. In some embodiments, formulations include a pharmaceutically acceptable carrier in addition to at least one active ingredient, such as a subject compound. In other embodiments, other medicinal or pharmaceutical agents, for example, with similar, related or complementary effects on the disease or condition being treated can also be included as active ingredients in a pharmaceutical composition.
Pharmaceutically acceptable carriers useful for the disclosed methods and compositions may depend on the particular mode of administration being employed. For example, parenteral formulations may include injectable fluids, such as, but not limited to, pharmaceutically and physiologically acceptable fluids such as water, physiological saline, balanced salt solutions, aqueous dextrose, glycerol or the like as a vehicle. For solid compositions (e.g., powder, pill, tablet, or capsule forms), non-toxic solid carriers can include, for example, pharmaceutical grades of mannitol, lactose, starch, or magnesium stearate. In addition to biologically neutral carriers, pharmaceutical compositions to be administered can optionally contain minor amounts of non-toxic auxiliary substances (e.g., excipients), such as wetting or emulsifying agents, preservatives, and pH buffering agents and the like; for example, sodium acetate or sorbitan monolaurate. Other examples of excipients include, nonionic solubilizers, such as cremophor, or proteins, such as human serum albumin or plasma preparations.
Some examples of materials which can serve as pharmaceutically-acceptable carriers include: (1) sugars, such as lactose, glucose and sucrose; (2) starches, such as corn starch and potato starch; (3) cellulose, and its derivatives, such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; (4) powdered tragacanth; (5) malt; (6) gelatin; (7) talc; (8) excipients, such as cocoa butter and suppository waxes; (9) oils, such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; (10) glycols, such as propylene glycol; (11) polyols, such as glycerin, sorbitol, mannitol, and polyethylene glycol; (12) esters, such as ethyl oleate and ethyl laurate; (13) agar; (14) buffering agents, such as magnesium hydroxide and aluminum hydroxide; (15) alginic acid; (16) water (e.g., pyrogen-free water); (17) isotonic saline; (18) Ringer's solution; (19) ethyl alcohol; (20) pH buffered solutions; (21) polyesters, polycarbonates and/or polyanhydrides; and (22) other non-toxic compatible substances employed in pharmaceutical formulations.
The disclosed pharmaceutical compositions may be formulated as a pharmaceutically acceptable salt of a disclosed compound. Pharmaceutically acceptable salts are non-toxic salts of a free base form of a compound that possesses the desired pharmacological activity of the free base. These salts may be derived from inorganic or organic acids. Non-limiting examples of suitable inorganic acids are hydrochloric acid, nitric acid, hydrobromic acid, sulfuric acid, hydroiodic acid, and phosphoric acid. Non-limiting examples of suitable organic acids are acetic acid, propionic acid, glycolic acid, lactic acid, pyruvic acid, malonic acid, succinic acid, malic acid, maleic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, methyl sulfonic acid, salicylic acid, formic acid, trichloroacetic acid, trifluoroacetic acid, gluconic acid, asparagic acid, aspartic acid, benzenesulfonic acid, para-toluenesulfonic acid, naphthalenesulfonic acid, and the like. In certain embodiments, the pharmaceutically acceptable salt includes formic acid. In certain embodiments, the pharmaceutically acceptable salt includes trifluoroacetic acid. Other suitable pharmaceutically acceptable salts are found in Remington's Pharmaceutical Sciences, 17th Edition, Mack Publishing Company, Easton, Pa., 1985. A pharmaceutically acceptable salt may also serve to adjust the osmotic pressure of the composition.
A subject compound can be used alone or in combination with appropriate additives to make tablets, powders, granules or capsules, for example, with conventional additives, such as lactose, mannitol, corn starch or potato starch; with binders, such as crystalline cellulose, cellulose derivatives, acacia, corn starch or gelatins; with disintegrators, such as corn starch, potato starch or sodium carboxymethylcellulose; with lubricants, such as talc or magnesium stearate; and if desired, with diluents, buffering agents, moistening agents, preservatives and flavoring agents. Such preparations can be used for oral administration.
A subject compound can be formulated into preparations for injection by dissolving, suspending or emulsifying the compound in an aqueous or nonaqueous solvent, such as vegetable or other similar oils, synthetic aliphatic acid glycerides, esters of higher aliphatic acids or propylene glycol; and if desired, with conventional additives such as solubilizers, isotonic agents, suspending agents, emulsifying agents, stabilizers and preservatives. The preparation may also be emulsified or the active ingredient encapsulated in liposome vehicles. Formulations suitable for injection can be administered by an intravitreal, intraocular, intramuscular, subcutaneous, sublingual, or other route of administration, e.g., injection into the gum tissue or other oral tissue. Such formulations are also suitable for topical administration.
In some embodiments, a subject compound can be delivered by a continuous delivery system. The term “continuous delivery system” is used interchangeably herein with “controlled delivery system” and encompasses continuous (e.g., controlled) delivery devices (e.g., pumps) in combination with catheters, injection devices, and the like, a wide variety of which are known in the art.
A subject compound can be utilized in aerosol formulation to be administered via inhalation. A subject compound can be formulated into pressurized acceptable propellants such as dichlorodifluoromethane, propane, nitrogen and the like.
Furthermore, a subject compound can be made into suppositories by mixing with a variety of bases such as emulsifying bases or water-soluble bases. A subject compound can be administered rectally via a suppository. The suppository can include vehicles such as cocoa butter, carbowaxes and polyethylene glycols, which melt at body temperature, yet are substantially solid at room temperature.
The term “unit dosage form,” as used herein, refers to physically discrete units suitable as unitary dosages for human and animal subjects, each unit containing a predetermined quantity of a subject compound calculated in an amount sufficient to produce the desired effect in association with a pharmaceutically acceptable diluent, carrier or vehicle. The specifications for a subject compound depend on the particular compound employed and the effect to be achieved, and the pharmacodynamics associated with each compound in the host.
The dosage form of a disclosed pharmaceutical composition may be determined by the mode of administration chosen. For example, in addition to injectable fluids, topical or oral dosage forms may be employed. Topical preparations may include eye drops, ointments, sprays and the like. Oral formulations may be liquid (e.g., syrups, solutions or suspensions), or solid (e.g., powders, pills, tablets, or capsules). Methods of preparing such dosage forms are known, or will be apparent, to those skilled in the art.
Certain embodiments of the pharmaceutical compositions that include a subject compound may be formulated in unit dosage form suitable for individual administration of precise dosages. The amount of active ingredient administered may depend on the subject being treated, the severity of the affliction, and the manner of administration, and is known to those skilled in the art. In certain instances, the formulation to be administered contains a quantity of the compounds disclosed herein in an amount effective to achieve the desired effect in the subject being treated.
Each therapeutic compound can independently be in any dosage form, such as those described herein, and can also be administered in various ways, as described herein. For example, the compounds may be formulated together, in a single dosage unit (that is, combined together in one form such as capsule, tablet, powder, or liquid, etc.) as a combination product. Alternatively, when not formulated together in a single dosage unit, an individual subject compound may be administered at the same time as another therapeutic compound or sequentially, in any order thereof.
The subject compounds can inhibit a protein kinase C (PKC) activity. Accordingly, the subject compounds are useful for treating a disease or disorder that is mediated through the activity of a PKC activity in a subject. In certain embodiments, the subject compounds are useful for treating a disease or disorder that is associated with the activation of T-cells in a subject.
The route of administration may be selected according to a variety of factors including, but not limited to, the condition to be treated, the formulation and/or device used, the patient to be treated, and the like. Routes of administration useful in the disclosed methods include but are not limited to oral and parenteral routes, such as intravenous (iv), intraperitoneal (ip), rectal, topical, ophthalmic, nasal, and transdermal. Formulations for these dosage forms are described herein.
An effective amount of a subject compound may depend, at least, on the particular method of use, the subject being treated, the severity of the affliction, and the manner of administration of the therapeutic composition. A “therapeutically effective amount” of a composition is a quantity of a specified compound sufficient to achieve a desired effect in a subject (e.g., patient) being treated. For example, this may be the amount of a subject compound necessary to prevent, inhibit, reduce or relieve a disease or disorder that is mediated through the activity of a PKC activity in a subject. Ideally, a therapeutically effective amount of a compound is an amount sufficient to prevent, inhibit, reduce or relieve a disease or disorder that is mediated through the activity of a PKC activity in a subject without causing a substantial cytotoxic effect on host cells.
Therapeutically effective doses of a subject compound or pharmaceutical composition can be determined by one of skill in the art, with a goal of achieving local (e.g., tissue) concentrations that are at least as high as the IC50 of an applicable compound disclosed herein.
An example of a dosage range is from 0.1 to 200 mg/kg body weight orally in single or divided doses. In some embodiments, a dosage range is from 1.0 to 100 mg/kg body weight orally in single or divided doses, including from 1.0 to 50 mg/kg body weight, from 1.0 to 25 mg/kg body weight, from 1.0 to 10 mg/kg body weight (assuming an average body weight of approximately 70 kg; values may be adjusted accordingly for persons weighing more or less than average). For oral administration, the compositions are, for example, provided in the form of a tablet containing from about 10 to about 1000 mg of the active ingredient, such as 25 to 750 mg, or 50 to 500 mg, for example 75 mg, 100 mg, 200 mg, 250 mg, 400 mg, 500 mg, 600 mg, 750 mg, or 1000 mg of the active ingredient for the symptomatic adjustment of the dosage to the subject being treated. In certain embodiments of an oral dosage regimen, a tablet containing from 500 mg to 1000 mg active ingredient is administered once (e.g., a loading dose) followed by administration of ½ (i.e., half) dosage tablets (e.g., from 250 to 500 mg) each 6 to 24 hours for 3 days or more.
The specific dose level and frequency of dosage for any particular subject may be varied and may depend upon a variety of factors, including the activity of the subject compound, the metabolic stability and length of action of that compound, the age, body weight, general health, sex and diet of the subject, mode and time of administration, rate of excretion, drug combination, and severity of the condition of the host undergoing therapy.
Embodiments of the present disclosure also include combinations of one or more disclosed compounds with one or more other agents or therapies useful in the treatment of a disease or disorder. In certain instances, the disease or disorder is mediated through the activity of a PKC activity in a subject. In certain instances, the disease or disorder is cell proliferative disorder. For example, one or more disclosed compounds may be administered in combination with therapeutically effective doses of other medicinal and pharmaceutical agents, or in combination other non-medicinal therapies, such as hormone or radiation therapy. The term “administration in combination with” refers to both concurrent and sequential administration of the active agents.
Protein Kinase C (PKC)
PKC is a family of enzymes that function as serine/threonine kinases. The isoenzymes of PKC differ in their tissue distribution, enzymatic selectivity, requirement for Ca2+, and regulation. PKCs play an important role in cell-cell signaling, gene expression and in the control of cell differentiation and growth.
The subject compound can be a selective inhibitor of PKC, e.g. an inhibitor selective for PKC over one or more other protein kinases, e.g. over one or more tyrosine kinases, for instance, over one or more non-receptor or receptor tyrosine kinases, e.g. over one or more of PKA, PKB, Abl Met, Src, Ins-R, Flt-3, JAK-2, KDR and/or Ret proteins. The selective PKC inhibitors may optionally be selective over one or more serine/threonine kinases, e.g. one or more serine/threonine kinases which do not belong to the CDK family. The subject compounds can exhibit a selectivity of at least 10 fold, or 20 fold, or 100 fold for the PKC over one or more other protein kinases, e.g. over one or more tyrosine kinases, e.g. over Flt-3, JAK-2, KDR and/or Ret proteins, or over one or more serine/threonine kinases which do not belong to the CDK family.
The selectivity of a selective inhibitor of PKC over other protein kinases may be calculated as the ratio of the IC50 measured for PKC in an assay described herein over the IC50 determined for another kinase. In a certain instance, there is provided a PKC inhibitor for which the ratio of the IC50 value as determined in an Allogeneic Mixed Lymphocyte Reaction (MLR) assay to the IC50 value as determined in a Bone Marrow Proliferation (BM) assay is higher than 5, 10, 20, or 30. MLR and BM assays can be done according to known methods, e.g. mouse or human MLR and BM assays, such as disclosed herein.
The disclosure provides an inhibitor of PKC, which can be an isozyme-selective PKC inhibitor, wherein the subject compound possesses selectivity for the isoforms θ and a of PKC over one or more of the other PKC isoforms. In a certain instance, the subject compound possesses selectivity for the isoform θ of PKC over one or more of the other PKC isoforms. In a certain instance, the subject compound possesses selectivity for the isoform α of PKC over one or more of the other PKC isoforms. In one embodiment, the disclosed compounds exhibit selectivity for PKC θ and PKC α over at least one PKC isoform.
A subject compound can show a selectivity of at least 10 fold, or 20 fold, or 100 fold for the isoforms θ or a of PKC over one or more of the other PKC isoforms. Selectivity for the isoforms θ or a of PKC over one or more of the other PKC isoforms can be measured by comparing the IC50 of the subject compound for the isoforms θ or a of PKC to the IC50 of the subject compound for the other PKC isoforms. In certain instances, the selectivity can be determined by calculating the ratio of IC50 of the subject compound for the other isoforms of PKC to the IC50 of the subject compound for θ or α isoforms of PKC. In certain examples subject compounds exhibit a selectivity for PKC θ, α or both over another PKC isoform of at least about 2-fold, such as from about 3-fold to about 300-fold, from about 10-fold to about 100-fold or from about 5-fold to 50-fold. IC50 values are obtained, for example, according to PKC assays described herein. The subject compounds can show an IC50 value for the isoforms θ or α of PKC of 1 μM or less, such as less than about 300 nM, such as from about 1 nM to about 250 nM, less than 100 nM or even less than 10 nM in the assays disclosed herein.
The subject compounds can show a selectivity of the isoforms θ or μ of PKC over other isoforms of PKC, as well as a selectivity over one or more of the other protein kinases, e.g. over one or more tyrosine kinases, or over one or more serine/threonine kinases which do not belong to the CDK-family, e.g. over one or more of PKA, PKB, Abl, Met, Src, Ins-it, Flt-3, JAK-2, KDR and Ret proteins, e.g. over one or more of Flt-3, JAK-2, KDR and Ret proteins.
Certain isozymes of PKC have been implicated in the mechanisms of various disease states, including, but not necessarily limited to, the following: cancer (PKC α, βI, βII, and δ); cardiac hypertrophy and heart failure (PKC βI and PKC βII) nociception (PKC γ and ε); ischemia including myocardial infarction (PKC ε and δ); immune response, particularly T-cell mediated (PKC θ and α); and fibroblast growth and memory (PKC δ and ζ). The role of PKC ε is also implicated in pain perception. PKC inhibitors can also be used for treating an ocular disease or disorder involving inflammatory and/or neovascular events.
The subject compounds can be used in the treatment of mammalian (especially human) disease states characterized by aberrant, elevated activity of a PKC isozyme in a tissue as compared to non-disease tissue of the same origin. PKC isozymes and disease states and/or biological functions amenable to therapy by inhibition of activity of the PKC isozyme include, but are not necessarily limited to: PKC α (hyperproliferative cellular diseases, such as cancer); PKC βI and PKC βII (cardiac hypertrophy and heart failure); PKC γ (pain management); PKC δ (ischemia, hypoxia (e.g., such as in myocardial infarction and in stroke); apoptosis induced by UV irradiation; and aberrant fibroblast growth (e.g., as may occur in wound healing)); PKC ε (pain management, myocardial dysfunction); PKC θ (immune system diseases, particularly those involving T-cell mediated responses); and PKC ζ (memory and fibroblast growth).
PKC Theta
PKC θ is expressed predominantly in lymphoid tissue and skeletal muscle. PKC θ is selectively expressed in T-cells and plays a role in mature T-cell activation. It has been shown that PKC θ is involved in T-cell receptor (TCR)-mediated T-cell activation but inessential during TCR-dependent thymocyte development. PKC θ, but not other PKC isoforms, translocates to the site of cell contact between antigen-specific T-cells and antigen presenting cells (APC), where it localizes with the TCR in the central core of the T-cell activation. PKC θ, but not the α, ε, or ζ isoenzymes, can selectively activate a FasL promoter-reporter gene and upregulate the mRNA or cell surface expression of endogenous FasL. On the other hand, PKC θ and c can promote T-cell survival by protecting the cells from Fas-induced apoptosis, and this protective effect was mediated by promoting p90Rsk-dependent phosphorylation of BCL-2 family member BAD. Thus, PKC θ appears to play a dual regulatory role in T-cell apoptosis.
PKC θ inhibitors can find use in the treatment or prevention of disorders or diseases mediated by T lymphocytes, for example, autoimmune disease such as rheumatoid arthritis, psoriasis and lupus erythematosus, and inflammatory disease such as asthma and inflammatory bowel diseases.
PKC θ is a drug target for immunosuppression in transplantation and autoimmune diseases (Isakov et al. (2002) Annual Review of Immunology, 20, 761-794). PCT Publication WO2004/043386 identifies PKC θ as a target for treatment of transplant rejection and multiple sclerosis. PKC θ also plays a role in inflammatory bowel disease (The Journal of Pharmacology and Experimental Therapeutics (2005), 313 (3), 962-982), asthma (WO 2005062918), and lupus (Current Drug Targets: Inflammation & Allergy (2005), 4 (3), 295-298).
In addition, PKC θ is highly expressed in gastrointestinal stromal tumors (Blay, P. et al. (2004) Clinical Cancer Research, 10, 12, Pt. 1), it has been suggested that PKC θ is a molecular target for treatment of gastrointestinal cancer (Wiedmann, M. et al. (2005) Current Cancer Drug Targets 5(3), 171).
Experiments induced in PKC θ knock-out mice led to the conclusion that PKC θ inactivation prevented fat-induced defects in insulin signalling and glucose transport in skeletal muscle (Kim J. et al, 2004, The J. of Clinical Investigation 114 (6), 823). This data indicates PKC θ is a therapeutic target for the treatment of type 2 diabetes, and hence PKC θ inhibitors can be useful for treating such disease.
The subject compounds are useful for treating a disease or disorder that is mediated through, or exacerbated by, the activity of a PKC in a subject in need of treatment. Also, the compounds are useful for treating a disease or disorder that is associated with aberrant or otherwise undesirable T cell activation in a subject.
Accordingly, the present disclosure provides methods of treating an inflammatory disease in a subject by administering an effective amount of a subject compound, including a salt or solvate or stereoisomer thereof, so as to treat inflammation. Inflammatory diseases contemplated for therapy include acute and chronic inflammation mediated or exacerbated by PKC activity.
The present disclosure also provides methods of treating an autoimmune disease in a subject by administering to the subject an effective amount of a subject compound, including a salt or solvate or stereoisomer thereof, so as to treat the autoimmune disease.
The present disclosure also provides methods of treating an ocular disease or disorder involving inflammatory and/or neovascular events by administration of a subject compound, including a salt or solvate or stereoisomer thereof, in an effective amount.
Diseases or conditions of interest for treatment according to the present disclosure include, but are not limited to, atherosclerosis, vascular occlusion due to vascular injury such as angioplasty, restenosis, obesity, syndrome X, impaired glucose tolerance, polycystic ovary syndrome, hypertension, heart failure, chronic obstructive pulmonary disease, CNS diseases such as Alzheimer disease or amyotrophic lateral sclerosis, cancer, infectious diseases such as: AIDS, septic shock or adult respiratory distress syndrome, ischemia/reperfusion injury, e.g., myocardial infarction, stroke, gut ischemia, renal failure or hemorrhage shock, and traumatic shock, e.g., traumatic brain injury.

Generally, cell proliferative disorders treatable with the subject compound disclosed herein relate to any disorder characterized by aberrant cell proliferation. These include various tumors and cancers, benign or malignant, metastatic or non-metastatic. Specific properties of cancers, such as tissue invasiveness or metastasis, can be targeted using the methods described herein. Cell proliferative disorders include a variety of cancers, including, among others, breast cancer, ovarian cancer, renal cancer, gastrointestinal cancer, kidney cancer, bladder cancer, pancreatic cancer, lung squamous carcinoma, and adenocarcinoma.
In some embodiments, the cell proliferative disorder treated is a hematopoietic neoplasm, which is aberrant growth of cells of the hematopoietic system. Hematopoietic malignancies can have its origins in pluripotent stem cells, multipotent progenitor cells, oligopotent committed progenitor cells, precursor cells, and terminally differentiated cells involved in hematopoiesis. Some hematological malignancies are believed to arise from hematopoietic stem cells, which have the ability for self renewal. For instance, cells capable of developing specific subtypes of acute myeloid leukemia (AML) upon transplantation display the cell surface markers of hematopoietic stem cells, implicating hematopoietic stem cells as the source of leukemic cells. Blast cells that do not have a cell marker characteristic of hematopoietic stem cells appear to be incapable of establishing tumors upon transplantation (Blaire et al., 1997, Blood 89:3104-3112). The stem cell origin of certain hematological malignancies also finds support in the observation that specific chromosomal abnormalities associated with particular types of leukemia can be found in normal cells of hematopoietic lineage as well as leukemic blast cells. For instance, the reciprocal translocation t(9q34;22q11) associated with approximately 95% of chronic myelogenous leukemia appears to be present in cells of the myeloid, erythroid, and lymphoid lineage, suggesting that the chromosomal aberration originates in hematopoietic stem cells. A subgroup of cells in certain types of CML displays the cell marker phenotype of hematopoietic stem cells.
Although hematopoietic neoplasms often originate from stem cells, committed progenitor cells or more terminally differentiated cells of a developmental lineage can also be the source of some leukemias. For example, forced expression of the fusion protein Bcr/Abl (associated with chronic myelogenous leukemia) in common myeloid progenitor or granulocyte/macrophage progenitor cells produces a leukemic-like condition. Moreover, some chromosomal aberrations associated with subtypes of leukemia are not found in the cell population with a marker phenotype of hematopoietic stem cells, but are found in a cell population displaying markers of a more differentiated state of the hematopoietic pathway (Turhan et al., 1995, Blood 85:2154-2161). Thus, while committed progenitor cells and other differentiated cells may have only a limited potential for cell division, leukemic cells may have acquired the ability to grow unregulated, in some instances mimicking the self-renewal characteristics of hematopoietic stem cells (Passegue et al., Proc. Natl. Acad. Sci. USA, 2003, 100:11842-9).
In some embodiments, the hematopoietic neoplasm treated is a lymphoid neoplasm, where the abnormal cells are derived from and/or display the characteristic phenotype of cells of the lymphoid lineage. Lymphoid neoplasms can be subdivided into B-cell neoplasms, T and NK-cell neoplasms, and Hodgkin's lymphoma. B-cell neoplasms can be further subdivided into precursor B-cell neoplasm and mature/peripheral B-cell neoplasm. Exemplary B-cell neoplasms are precursor B-lymphoblastic leukemia/lymphoma (precursor B-cell acute lymphoblastic leukemia) while exemplary mature/peripheral B-cell neoplasms are B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma, B-cell prolymphocytic leukemia, lymphoplasmacytic lymphoma, splenic marginal zone B-cell lymphoma, hairy cell leukemia, plasma cell myeloma/plasmacytoma, extranodal marginal zone B-cell lymphoma of MALT type, nodal marginal zone B-cell lymphoma, follicular lymphoma, mantle-cell lymphoma, diffuse large B-cell lymphoma, mediastinal large B-cell lymphoma, primary effusion lymphoma, and Burkitt's lymphoma/Burkitt cell leukemia. T-cell and Nk-cell neoplasms are further subdivided into precursor T-cell neoplasm and mature (peripheral) T-cell neoplasms. Exemplary precursor T-cell neoplasm is precursor T-lymphoblastic lymphoma/leukemia (precursor T-cell acute lymphoblastic leukemia) while exemplary mature (peripheral) T-cell neoplasms are T-cell prolymphocytic leukemia T-cell granular lymphocytic leukemia, aggressive NK-cell leukemia, adult T-cell lymphoma/leukemia (HTLV-1), extranodal NK/T-cell lymphoma, nasal type, enteropathy-type T-cell lymphoma, hepatosplenic gamma-delta T-cell lymphoma, subcutaneous panniculitis-like T-cell lymphoma, Mycosis fungoides/Sezary syndrome, Anaplastic large-cell lymphoma, T/null cell, primary cutaneous type, Peripheral T-cell lymphoma, not otherwise characterized, Angioimmunoblastic T-cell lymphoma, Anaplastic large-cell lymphoma, T/null cell, primary systemic type. The third member of lymphoid neoplasms is Hodgkin's lymphoma, also referred to as Hodgkin's disease. Exemplary diagnosis of this class that can be treated with the compounds include, among others, nodular lymphocyte-predominant Hodgkin's lymphoma, and various classical forms of Hodgkin's disease, exemplary members of which are Nodular sclerosis Hodgkin's lymphoma (grades 1 and 2), Lymphocyte-rich classical Hodgkin's lymphoma, Mixed cellularity Hodgkin's lymphoma, and Lymphocyte depletion Hodgkin's lymphoma.
In some embodiments, the hematopoietic neoplasm treated is a myeloid neoplasm. This group comprises a large class of cell proliferative disorders involving or displaying the characteristic phenotype of the cells of the myeloid lineage. Myeloid neoplasms can be subdivided into myeloproliferative diseases, myelodysplastic/myeloproliferative diseases, myelodysplastic syndromes, and acute myeloid leukemias. Exemplary myeloproliferative diseases are chronic myelogenous leukemia (e.g., Philadelphia chromosome positive (t(9;22)(qq34;q11)), chronic neutrophilic leukemia, chronic eosinophilic leukemialhypereosinophilic syndrome, chronic idiopathic myelofibrosis, polycythemia vera, and essential thrombocythemia. Exemplary myelodysplastic/myeloproliferative diseases are chronic myelomonocytic leukemia, atypical chronic myelogenous leukemia, and juvenile myelomonocytic leukemia. Exemplary myelodysplastic syndromes are refractory anemia, with ringed sideroblasts and without ringed sideroblasts, refractory cytopenia (myelodysplastic syndrome) with multilineage dysplasia, refractory anemia (myelodysplastic syndrome) with excess blasts, 5q-syndrome, and myelodysplastic syndrome with t(9;12)(q22;p12) (TEL-Syk fusion; see, e.g., Kuno et al., 2001, Blood 97:1050).
In some embodiments, the composition can be used to treat acute myeloid leukemias (AML), which represent a large class of myeloid neoplasms having its own subdivision of disorders. These subdivisions include, among others, AMLs with recurrent cytogenetic translocations, AML with multilineage dysplasia, and other AML not otherwise categorized. Exemplary AMLs with recurrent cytogenetic translocations include, among others, AML with t(8;21)(q22;q22), AML1(CBF-alpha)/ETO, Acute promyelocytic leukemia (AML with t(15;17)(q22;q11-12) and variants, PML/RAR-alpha), AML with abnormal bone marrow eosinophils (inv(16)(p13q22) or t(16;16)(p13;q11), CBFb/MYH11X), and AML with 11q23 (MLL) abnormalities. Exemplary AML with multilineage dysplasia are those that are associated with or without prior myelodysplastic syndrome. Other acute myeloid leukemias not classified within any definable group include, AML minimally differentiated, AML without maturation, AML with maturation, Acute myelomonocytic leukemia, Acute monocytic leukemia, Acute erythroid leukemia, Acute megakaryocytic leukemia, Acute basophilic leukemia, and Acute panmyelosis with myelofibrosis.
In other aspects, cell proliferative disorders comprise virally mediated tumors. These can arise from infection of cells by an oncogenic virus that has the capability of transforming a normal cell into a tumor cell. Because rates of viral infection far exceed the number of actual incidence of cell transformation, viral mediated transformation generally act together with other cellular factors to generate a transformed tumor cell. Thus, a virally mediated tumor does not require the virus to be the sole causative agent of the cell proliferative disorder, but rather that the viral infection or persistent presence of virus is associated with the generation of the tumor. Generally, tumors where the causative agent is a virus typically has continual expression of a limited number of viral genes and that viral these oncogenes, expressed as part of the viral infection or through persistence of the virus, disrupts the normal cellular gene expression and signal transduction pathways. Without being bound by theory, viral oncogenes involved in cell transformation appear to disrupt four main cellular processes: cell surface receptors that interact with growth factors and extracellular matrix, transmembrane signaling networks, cytosolic elements such as soluble proteins and second messengers, and nuclear proteins including DNA binding proteins and factors which function directly and indirectly in gene regulation and replication.
The following are examples of assays useful in characterizing activities of a compound of the present disclosure.
1. Protein Kinase C Assay
The inhibition of PKC activity is measured by monitoring the production of phosphorylated peptide by fluorescence polarization at different concentrations of the inhibitor. Reactions are carried out in 96-well plate format with a total volume of 20 μL containing 20 mM HEPES, pH 7.4, 5 mM MgCl2, 0.2 mM CaCl2, 1 mM DTT, 0.02% Brij-35, 0.1 mg/ml phosphatidylserine, 0.02 mg/ml dioleoyl-sn-glycerol and 5 μM each of ATP and the peptide substrate. Compounds are first diluted serially in DMSO and then transferred to a solution containing the above concentrations of HEPES, MgCl2, CaCl2, DTT, and Brij-35 to yield 5× compound solutions in 2% DMSO, which is then added to the reaction solution. Reactions are initiated by the addition of PKC at a typical concentration as described in the table below, and then allowed to incubate at room temperature for 20 minutes. At the end of this time, a combination of quench (EDTA) and detection (peptide tracer and antibody) reagents is added using the protocol of Invitrogen P2748 (Carlsbad, Calif.), a Protein Kinase C Fluorescence polarization Assay Kit. After a 30 minute period of incubation, the amount of phosphorylated peptide generated is measured by fluorescence polarization (Ex=485 nm, Em=535 nm) using a Tecan Polarian instrument (Switzerland).
2. IL-2 ELISA, Human Primary T Cell, Anti-CD3+CD28+ Assays
Human Primary T Cell Isolation and Culture:
Human primary T cells were prepared as follows. Fresh PBMC's from All Cells (Cat #PB002) were re-suspended in RPMI (RPMI-1640 with L-Glutamine; Mediatech, Inc., Herndon Va., cat. #10-040-CM) with 10% FBS and seeded into flasks and incubated at 37° C. for 2 hours to allow the monocytes to adhere. The non-adherent cells were then centrifuged and re-suspended in RPMI medium containing 40 U/ml IL2 and seeded into a flask pre-coated with 1 μg/ml aCD3 and 5 ug/ml aCD28 (Anti-Human CD3, BD Pharmingen Catalog #555336, Anti-Human CD28, Beckman Coulter Catalog #1M1376). The cells were stimulated for 3-4 days, then transferred to a fresh flask and maintained in RPMI (RPMI-1640 with L-Glutamine; Mediatech, Inc., Herndon Va., cat. #10-040-CM) with 10% FBS and 40 U/ml IL-2.
Primary T Cell Stimulation and IL2 ELISA:
Human primary T cells (100,000 cells per well) were pre-incubated with or without test compound in RPMI-1640 with L-Glutamine and 10% FBS for 1 hour at 37° C. Cells were then stimulated by transferring them to round-bottom 96-well plates pre-coated with 1 μg/ml aCD3 and 5 μg/ml aCD28. For counter assay, cells were instead stimulated by adding 8× stock solutions of PMA and ionomycin in RPMI-1640 with L-Glutamine and 10% FBS (for final concentrations of 0.5 ng/ml PMA and 0.1 μM ionomycin, both from Calbiochem). Cells were incubated at 37° C. for 24 hours before 100 μL supernatants were harvested for quantification of IL-2 by ELISA using Human IL-2 Duoset ELISA Kit from R and D Systems, Cat. #DY202E.

Incubation is performed for 60 minutes at room temperature. Reaction is stopped by adding 50 μl of stop mix (100 mM EDTA, 200 μM ATP, 0.1% Triton X-100, 0.375 mg/well streptavidin-coated SPA beads in phosphate buffered saline w/o Ca, Mg. After 10 minutes incubation at room temperature, the suspension is spun down for 10 minutes at 300 g. Incorporated radioactivity is measured in a Trilux counter for 1 minute. IC50 measurement is performed on a routine basis by incubating a serial dilution of inhibitor at concentrations ranging between 1-1000 μM.

10. CD28 Costimulation Assay
The assay is performed with Jurkat cells transfected with a human interleukin-2 promoter/reporter gene construct as described by Baumann G et al. in Transplant. Proc. 1992; 24:43-8, the β-galactosidase reporter gene being replaced by the luciferase gene (de Wet J., et al., Mol. Cell. Biol. 1987, 7(2), 725-737). Cells are stimulated by solid phase-coupled antibodies or phorbol myristate acetate (PMA) and the Ca++ ionophore ionomycin as follows. For antibody-mediated stimulation Microlite TM1 microtiter plates (Dynatech) are coated with 3 μg/ml goat anti-mouse IgG Fc antibodies (Jackson) in 55 μl phosphate-buffered saline (PBS) per well for three hours at room temperature. Plates are blocked after removing the antibodies by incubation with 2% bovine serum albumin (BSA) in PBS (300 μl per well) for 2 hours at room temperature. After washing three times with 300 μl PBS per well, 10 ng/ml anti-T cell receptor antibodies (WT31, Becton & Dickinson) and 300 ng/ml anti-CD28 antibodies (15E8) in 50 μl 2% BSA/PBS are added as stimulating antibodies and incubated overnight at 4° C. Finally the plates are washed three times with 300 μl PBS per well. Seven three-fold serial dilutions of test compounds in duplicates in assay medium (RPMI 1640/10% fetal calf serum (FCS) containing 50 μM 2-mercaptoethanol, 100 units/ml penicillin and 100 μg/ml streptomycin) are prepared in separate plates, mixed with transfected Jurkat cells (clone K22 290_H23) and incubated for 30 minutes at 37° C. in 5% CO2 100 μl of this mixture containing 1×105 cells are then transferred to the antibody-coated assay plates. In parallel 100 μl are incubated with 40 ng/ml PMA and 2 μM ionomycin. After incubation for 5.5 hours at 37° C. in 5% CO2, the level of luciferase is determined by bioluminescence measurement. The plates are centrifuged for 10 minutes at 500 g and the supernatant is removed by flicking. Lysis buffer containing 25 mM Tris-phosphate, pH 7.8, 2 mM DTT, 2 mM 1,2-diaminocyclohexane-N,N,N′,N-tetraacetic acid, 10% (v/v) glycerol and 1% (v/v) Triton X-100 is added (20 μl per well). The plates are incubated at room temperature for 10 minutes under constant shaking. Luciferase activity is assessed with a bioluminescence reader (Labsystem, Helsinki, Finland) after automatic addition of 50 μl per well luciferase reaction buffer containing 20 mM Tricine, 1.07 mM (MgCO3)4Mg(OH)2×5H2O, 2.67 mM MgSO4, 0.1 mM EDTA, 33.3 mM DTT, 270 μM coenzyme A, 470 μM luciferin (Chemie Brunschwig AG), 530 μM ATP, pH 7.8. Lag time is 0.5 seconds, total measuring time is 1 or 2 seconds. Low control values are light units from anti-T cell receptor- or PMA-stimulated cells, high controls are from anti-T cell receptor/anti-CD28- or PMA/ionomycin-stimulated cells without any test sample. Low controls are subtracted from all values. The inhibition obtained in the presence of a test compound is calculated as percent inhibition of the high control. The concentration of test compounds resulting in 50% inhibition (IC50) is determined from the dose-response curves.
11. Bone Marrow Proliferation (BM) Assay
Bone marrow cells from CBA mice (2.5×104 cells per well in flat bottom tissue culture microtiter plates) are incubated in 100 μl RPMI medium containing 10% FCS, 100 U/ml penicillin, 100 μg/ml streptomycin (Gibco BRL, Basel, Switzerland), 50 UM 2-mercaptoethanol (Fluke, Buchs, Switzerland), WEHI-3 conditioned medium (7.5% v/v) and L929 conditioned medium (3% v/v) as a source of growth factors and serially diluted compounds. Seven three-fold dilution steps in duplicates per test compound are performed. After four days of incubation 1 μCi3H-thymidine is added. Cells are harvested after an additional five-hour incubation period, and incorporated 3H-thymidine is determined according to standard procedures. Conditioned media are prepared as follows. WEHI-3 cells 1 (ATCC TIB68) and L929 cells (ATCC CCL 1) are grown in RPMI medium until confluence for 4 days and one week, respectively. Cells are harvested, resuspended in the same culture flasks in medium C containing 1% FCS (Schreier and Tees 1981) for WEHI-3 cells and RPMI medium for L929 cells and incubated for 2 days (WEHI-3) or one week (L929). The supernatant is collected, filtered through 0.2 μm and stored in aliquots at −80° C. Cultures without test compounds and without WEHI-3 and L929 supernatants are used as low control values. Low control values are subtracted from all values. High controls without any sample are taken as 100% proliferation. Percent inhibition by the samples is calculated and the concentrations required for 50% inhibition (IC50 values) are determined.
12. Allogeneic Mixed Lymphocyte Reaction (MLR)
The two-way MLR is performed according to standard procedures (J. Immunol. Methods, 1973, 2, 279 and Meo T. et al., Immunological Methods, New York, Academic Press, 1979, 227-39). Briefly, spleen cells from CBA and BALB/c mice (1.6×105 cells from each strain per well in flat bottom tissue culture microtiter plates, 3.2×105 in total) are incubated in RPMI medium containing 10% FCS, 100 U/ml penicillin, 100 μg/ml streptomycin (Gibco BRL, Basel, Switzerland), 50 μM 2-mercaptoethanol (Fluka, Buchs, Switzerland) and serially diluted compounds. Seven three-fold dilution steps in duplicates per test compound are performed. After four days of incubation 1 μCi3H-thymidine is added. Cells are harvested after an additional five-hour incubation period, and incorporated 3H-thymidine is determined according to standard procedures. Background values (low control) of the MLR are the proliferation of BALB/c cells alone. Low controls are subtracted from all values. High controls without any sample are taken as 100% proliferation. Percent inhibition by the samples is calculated, and the concentrations required for 50% inhibition (IC50 values) are determined.
1. Heart Transplantation Model
The strain combination used: Male Lewis (RT1 haplotype) and BN (RT1 haplotype). The animals are anaesthetised using inhalational isofluorane. Following heparinisation of the donor rat through the abdominal inferior vena cava with simultaneous exsanguination via the aorta, the chest is opened and the heart rapidly cooled. The aorta is ligated and divided distal to the first branch and the brachiocephalic trunk is divided at the first bifurcation. The left pulmonary artery is ligated and divided and the right side divided but left open. All other vessels are dissected free, ligated and divided and the donor heart is removed into iced saline.
The recipient is prepared by dissection and cross-clamping of the infra-renal abdominal aorta and vena cava. The graft is implanted with end-to-side anastomoses, using 1010 monofilament suture, between the donor brachiocephalic trunk and the recipient aorta and the donor right pulmonary artery to the recipient vena cava. The clamps are removed, the graft tethered retroabdominally, the abdominal contents washed with warm saline and the animal is closed and allowed to recover under a heating lamp. Graft survival is monitored by daily palpation of the beating donor heart through the abdominal wall. Rejection is considered to be complete when-heart beat stops. Graft survival is monitored in animals treated with compounds.
2. Graft v. Host Model
Spleen cells (2×107) from Wistar/F rats are injected subcutaneously into the right hind footpad of (Wistar/F×Fischer 344)F1 hybrid rats. The left footpad is left untreated. The animals are treated with the test compounds on 4 consecutive days (0-3). The popliteal lymph nodes are removed on day 7, and the weight differences between two corresponding lymph nodes are determined. The results are expressed as the inhibition of lymph node enlargement (given in percent) comparing the lymph node weight differences in the experimental groups to the weight difference between the corresponding lymph nodes from a group of animals left untreated with a test compound. In certain instances the test compound is a selective PKC inhibitor. For example, disclosed compounds that are particularly useful for treating graft versus host disease and related disorders are selective PKC α and θ inhibitors.
3. Rat Collagen-Induced Arthritis Model
Rheumatoid arthritis (RA) is characterized by chronic joint inflammation eventually leading to irreversible cartilage destruction. IgG-containing IC are abundant in the synovial tissue of patients with RA. While it is still debated what role these complexes play in the etiology and pathology of the disease, IC communicate with the hematopoetic cells via the FcγR.
CIA is a widely accepted animal model of RA that results in chronic inflammatory synovitis characterized by pannus formation and joint degradation. In this model, intradermal immunization with native type II collagen, emulsified with incomplete Freund's adjuvant, results in an inflammatory polyarthritis within 10 or 11 days and subsequent joint destruction in 3 to 4 weeks.
4. Study Protocol
Syngeneic LOU rats are immunized with native type II collagen on Day 0, and efficacy of a test compound is evaluated in a prevention regimen and a treatment regimen. In the prevention protocol, either vehicle or various doses of a test compound are administered via oral gavage starting on day of immunization (Day 0). In the treatment protocol, after clinical signs of arthritis develop on Day 10, treatment with a test compound is initiated (e.g., 300 mg/kg by oral gavage, qd) and continued until sacrifice on Day 28. In both protocols, clinical scores are obtained daily, and body weights are measured twice weekly. At Day 28, radiographic scores are obtained, and serum levels of collagen II antibody are measured by ELISA.
5. Determination of Results
By 10 days after immunization, rats can develop clinical CIA, as determined by an increase in their arthritis scores. The mean arthritic score gradually increases in the rats treated with vehicle alone after Day 10, and by Day 28 the mean clinical score can reach about 6.75. Mean clinical scores in animals treated from the day of immunization (Day 0) with a test compound can be significantly reduced on Days 10-28 compared with vehicle controls. In the rats treated with a test compound at disease onset, there can be a significantly lower arthritis score beginning around Day 16, and this difference can be observed until the end of the study on Day 28.
Blinded radiographic scores (scale 0-6) can be obtained on Day 28 of CIA and compared between the animals in the vehicle group, animals in the prevention group, and animals in the treatment group.
The groups administered with a test compound, either prophylactically (at immunization) or after disease onset can preclude the development of erosions and reduced soft tissue swelling. Similarly, the groups administered with a test compound can result in reduction of serum anti-collagen II antibody.
6. Mouse Experimental Autoimmune Encephalomyelitis
The in vivo efficacy of a test compound towards autoimmune diseases can be demonstrated in a mouse model of experimental autoimmune encephalomyelitis (EAE).
7. Model Description
EAE is a useful model for multiple sclerosis (MS), an autoimmune disease of the CNS that is caused by immune-cell infiltration of the CNS white matter. Inflammation and subsequent destruction of myelin cause progressive paralysis. Like the human disease, EAE is associated with peripheral activation of T cells autoreactive with myelin proteins, such as myelin basic protein (MBP), proteolipid protein (PLP), or myelin oligodendrocyte protein (MOG). Activated neuroantigen-specific T cells pass the blood-brain barrier, leading to focal mononuclear cell infiltration and demyelination. EAE can be induced in susceptible mouse strains by immunization with myelin-specific proteins in combination with adjuvant. In the SJL mouse model used in these studies, hind limb and tail paralysis is apparent by Day 10 after immunization, the peak of disease severity can be observed between Days 10 and 14, and a cycle of partial spontaneous remission followed by relapse can be observed up to Day 35. The results can demonstrate the potential of the test compound to suppress disease severity and prevent relapse of disease symptoms that may be the result of FcγR-mediated cytokine release from immune cells.
8. Study Protocol
In the SJL murine model of EAE, each mouse is sensitized with PLP/CFA. (150 μg PLP139-151 with 200 μg CFA in 0.05 ml of homogenate on four sites of hind flank for a total of 0.2 ml emulsion is used to induce EAE). In a suppression protocol, either vehicle or various doses of a test compound are administered via oral gavage starting on the day of immunization (Day 0). In a treatment protocol, at onset of disease, animals are separated to achieve groups with a similar mean clinical score at onset and administered vehicle or various dose frequencies of test compounds via oral gavage. In both protocols, clinical scores are monitored daily, and body weights are measured twice weekly.
9. Determination of Results
By 10 days after PLP immunization, SJL mice can develop clinical EAE, as evidenced by an increase in their mean clinical scores. The paralytic score can gradually increase in the animals treated with vehicle only from the day of immunization (Day 0), and by Day 14 the mean score can reach a peak of about 5.1. At disease peak (e.g., Day 14), the mean clinical score in animals treated with either daily or twice daily can be significantly reduced. By Day 16, animals can exhibit a partial remission of mean clinical severity, which is a characteristic of the SJL model. The lower clinical scores in animals treated twice daily with a test compound can remain significant throughout the experiment until the animals are sacrificed on Day 30. These lower scores throughout the treatment period are reflected in the significantly lower cumulative disease index (CDI) and increase in cumulative weight index (CWI).
SJL mice treated with a test compound at disease onset (e.g., Day 11) can show a significant decrease in CDI. Further, there can be a decrease in the number of relapses in animals treated with a test compound compared with the number of relapses in animals treated with vehicle.
Since subject compounds can inhibit a PKC activity, such compounds are also useful as research tools. The present disclosure also provides a method for using subject compounds as a research tool for studying a biological system or sample, or for discovering new chemical compounds that can inhibit a PKC activity.
The disclosure provides for a method of studying a biological system or sample known to comprise PKC, the method comprising: (a) contacting the biological sample with a compound of formula I-IV or a salt or solvate or stereoisomer thereof; and (b) determining the inhibiting effects caused by the compound on the biological sample.
Any suitable biological sample having PKC can be employed in such studies which can be conducted either in vitro or in vivo. Representative biological samples suitable for such studies include, but are not limited to, cells, cellular extracts, plasma membranes, tissue samples, isolated organs, mammals (such as mice, rats, guinea pigs, rabbits, dogs, pigs, humans, and so forth), and the like, with mammals being of particular interest.
When used as a research tool, a biological sample comprising PKC is typically contacted with a PKC activity-inhibiting amount of a subject compound. After the biological sample is exposed to the compound, the effects of inhibition of a PKC activity are determined using conventional procedures and equipment, such as the assays disclosed herein. Exposure encompasses contacting the biological sample with the compound or administering the compound to a subject. The determining step can involve measuring a response (a quantitative analysis) or can involve making an observation (a qualitative analysis). Measuring a response involves, for example, determining the effects of the compound on the biological sample using conventional procedures and equipment, such as radioligand binding assays and measuring ligand-mediated changes in functional assays. The assay results can be used to determine the activity level as well as the amount of compound necessary to achieve the desired result, that is, a PKC activity-inhibiting amount.
Additionally, subject compounds can be used as research tools for evaluating other chemical compounds, and thus are also useful in screening assays to discover, for example, new compounds having a PKC inhibiting activity. In this manner, a subject compound can be used as a standard in an assay to allow comparison of the results obtained with a test compound and with the subject compounds to identify those test compounds that have about equal or superior activity, if any. For example, IC50 data for a test compound or a group of test compounds is compared to the IC50 data for a subject compound to identify those test compounds that have the desired properties, for example, test compounds having an IC50 about equal or superior to a subject compound, if any.
This aspect includes, as separate embodiments, both the generation of comparison data (using the appropriate assays) and the analysis of test data to identify test compounds of interest. Thus, a test compound can be evaluated in a biological assay, by a method comprising the steps of: (a) conducting a biological assay with a test compound to provide a first assay value; (b) conducting the biological assay with a subject compound to provide a second assay value; wherein step (a) is conducted either before, after or concurrently with step (b); and (c) comparing the first assay value from step (a) with the second assay value from step (b). The assays that can be used for generation of comparison data are disclosed herein, such as the PKC assays.

The lupinane amine.2HCl (1-[(1S,9aR)-octahydro-2H-quinolizin-1-yl]methanamine, CAS #: 75532-84-2, commercially available from ChemBridge, San Diego) (1.0 eq) was combined with 2,4-dichloro-5-X-pyrimidine (X=H, F, Cl, Me, CF3, CN, CONH2, OMe, NMe2) (1.0 eq) and NaHCO3 (1.2 eq). A mixture of MeOH:H2O (4/1) (concentration of the reaction mixture: ca. 0.1-0.5 M) was added and the resulting suspension was stirred for 1 d at RT. After the completion of the reaction was confirmed by TLC and HPLC, silica gel was added to the reaction mixture and solvents were evaporated under reduced pressure. The resulting solid was loaded on a CombiFlash column and further purified by flash chromatography eluting with DCM/MeOH—NH3 (2M) (gradient 0->10%).
The mono-SNAr product (50.0 mg, 1.0 eq) was dissolved in 4 ml of isopropyl alcohol in a 2 dram vial. p-Toluenesulfonic acid monohydrate (1.2 eq) and the desired aniline (1.5 eq) were added and the vial was sealed. After heating over night at 80° C. using an anodized aluminum heating block the solvent was boiled off by removing the cap. The product was isolated by preparative HPLC eluting with an acetonitrile/water gradient.
3-amino-4-fluorobenzonitrile (9.82 g, 72.1 mmol) was dissolved in acetonitrile to give a pale yellow solution. NBS (13.5 g, 75.7 mmol) was added in portions; the reaction mixture turned brown-blackish but remained a solution. After the completion of the reaction was confirmed by TLC and HPLC, silica gel was added to the reaction mixture and the solvent was evaporated under reduced pressure. The crude product was leaded on a CombiFlash column (330 g) and the product was eluted with hexanes/ethyl acetate (0→15% gradient). The clean fractions were combined to give 9.63 g (62%) of a yellowish off-white solid. More product was found in mixed fractions which were discarded. 1H NMR (300 MHz, dmso) δ 7.57 (d, J=10.9 Hz, 1H), 7.17 (d, J=8.7 Hz, 1H), 5.85 (s br, 2H); MS (ES) 213/215 (M−H).
The product from the above reaction (5-amino-2-bromo-4-fluorobenzonitrile) (4.0 g, 18.6 mmol), cyclo-propyl boronic acid (3.19 g, 37.2 mmol), Pd(OAc)2 (835 mg, 3.72 mmol), tricyclohexyl phosphine (1.04 g, 3.72 mmol), Cs2CO3 (36.3 g, 111.6 mmol) were combined in a pressure vessel. A mixture of toluene (110 ml) and H2O (35 ml) was added. The ensuing yellow-orange suspension was degassed and flushed with nitrogen gas (3×). The pressure vessel was sealed and heated over night (ca. 12 h) at 110° C. After checking the reaction by TLC and HPLC, the precipitate/salts were filtered off, more H2O was added and the mixture was extracted with ethyl acetate (3×). The combined organic phases were filtered through Na2SO4, silica gel was added and solvents were removed using a rotary evaporator. Further purification by CombiFlash (120 g column) eluting with hexanes/ethyl acetate (0→20% gradient) yielded 2.01 g (61%) of the desired product in form of a pale yellow, beige solid. 1H NMR (300 MHz, cdcl3) δ 6.98 (d, J=8.6 Hz, 1H), 6.58 (d, J=12.0 Hz, 1H), 3.81 (s br, 2H), 2.21-2.06 (m, 1H), 1.11-0.99 (m, 2H), 0.69-0.59 (m, 2H); MS (ES) 177 (M+H).

The inhibition of PKC-alpha, PKC-beta, PKC-delta, PKC epsilon and PKC-theta activity is determined via ELISA as follows: NUNC MAXISORP (#436110) or Costar High Binding (#3922) plates are coated with 0.01 mg/ml Neutravidin (Pierce #PI-31000) in 1×PBS (100 μL/well) for 18-24 hours at 4° C. When ready to be used, plates are washed with 1×PBST and then blocked with 2% BSA in 1×PBST (100 μL/well) for a minimum of 1 hour at room temperature. The reactions are conducted in a volume of 60 μL/well. When ready to begin, the plates are washed with 1×PBST to remove the 2% BSA blocking solution. Reaction solution containing the necessary buffer components as well as the appropriate concentrations of ATP and peptide substrate is then added to each well (see Table 3). Appropriate concentrations of test compound is then added—with the volume added should taking into consideration the DMSO tolerance of the kinases being about 0.2%. The reaction is then initiated by the addition of kinase—the approximate final concentration of which is listed in Table 3 (the concentration may vary depending on the batch to batch variability in the activity of enzymes). After allowing the reaction to stand at room temperature for 20 minutes, the plates are then washed with 1×PBST.
After removal of the reaction mixture from the plate and washing with 1×PBST, an antibody developing solution containing a 1:10,000 dilution of the appropriate primary and secondary antibodies (Table 3) in a 0.1% BSA solution in 1×PBST is then added to each well (100 μL/well). This is then allowed to stand at room temperature for a minimum of 1 hour. After this time, the plates are again washed with 1×PBST. The SuperSignal ELISA Pico Chemiluminescent substrate (Pierce #PI-37069) was then added (100 μL/well) and the plate is read on a luminescence plate reader.
Alternatively, the inhibition of PKC activity is measured by monitoring the production of phosphorylated peptide by fluorescence polarization at different concentrations of the inhibitor. Reactions are carried out in 96-well plate format with a total volume of 20 μL containing 20 mM HEPES, pH 7.4, 5 mM MgCl2, 0.2 mM CaCl2, 1 mM DTT, 0.02% Brij-35, 0.1 mg/ml phosphatidylserine, 0.02 mg/ml dioleoyl-sn-glycerol and 5 μM each of ATP and the peptide substrate. Compounds are first diluted serially in DMSO and then transferred to a solution containing the above concentrations of HEPES, MgCl2, CaCl2, DTT, and Brij-35 to yield 5× compound solutions in 2% DMSO, which is then added to the reaction solution. Reactions are initiated by the addition of PKC at a typical concentration as described in Table 4, and then allowed to incubate at room temperature for 20 minutes. At the end of this time, a combination of quench (EDTA) and detection (peptide tracer and antibody) reagents is added using the protocol of Invitrogen P2748. After a 30 minutes period of incubation, the amount of phosphorylated peptide generated is measured by fluorescence polarization (Ex=485 nm, Em=535 nm) using a Tecan Polarian instrument.
HEK-FLPTREX cells are stably transfected with pcDNA5/FRT/TO+hTRPV4a, rat TRPV1-HA or rTRPA1-HA are grown in Dulbecco's Modified Eagle's Medium (DMEM) containing 10% tetracycline-free fetal bovine serum, hygromycin (50 μg/ml) and blasticidin (10 μg/ml). Cells are treated with tetracycline (0.1 μg/ml, 20 h) to induce TRP expression. DRG from thoracic and lumbar spinal cord of rats or mice were minced in cold Hank's Balanced Salt Solution (HBSS) and incubated for 60 at 37° C. in DMEM containing 1 mg/ml of collagenase type IA and 0.1 mg/ml of DNAse type IV, pelleted and incubated with 0.25% trypsin for 30 minutes. Neurons are pelleted, suspended in DMEM containing 10% fetal bovine serum, 10% horse serum, 100 U/ml penicillin, 0.1 mg/ml streptomycin, 2 mM glutamine, dissociated by gentle trituration until the solution appears cloudy and homogeneous and plated on glass coverslips coated with PolyOnitine/laminin. Neurons are cultured for 3-4 days before the experiment.
Cells grown on coverslips or on a 96 multiwell plate are incubated in HBSS (pH 7.4) containing Ca2+ and Mg2+, 20 mM HEPES buffer, 0.1% BSA, 100 U/ml penicillin, 100 μg/ml streptomycin, with 2.5-5 μM Fura-2AM (Invitrogen) for 20-45 minutes at 37° C. Cells are washed and fluorescence is measured at 340 nm and 380 nm excitation and 510 nm emission in a F-2500 spectrophotometer, or in a Flexstation 3 Microplate Reader III (for the measurement of the calcium in the cell population) or using a Zeiss Axiovert microscope, an ICCD video camera and a video microscopy acquisition program (for the measurement of the calcium influx in the single neurons). Substances are injected directly into the chamber (20 ml into 2 ml, for the spectrophotometer; 20 ml in 200 ml for the Flexstation, 50 ml in 350 ml in the chamber for the single cells).
Mechanical pain is quantified as the number of times the hind paw is withdrawn in response to 5 applications of a 0.173 mN von Frey hair. Responses are expressed as a percentage (e.g. 3 withdrawals out of 5 are recorded as 60%) and mechanical hyperalgesia defined as increase in the percentage of withdrawal compared to basal measurement. 2) Mechanical pain is quantified using the ‘up-down paradigm’, determining the 50% response threshold to the von Frey filaments applied to the mid-plantar surface for 5 s or until a withdrawal response occurred. Von Frey filaments are in this range of intensities: 1.65, 2.44, 2.83, 3.22, 3.61, 3.84, 4.08.
Thermal hyperalgesia is assessed in mice using a plantar test apparatus and quantified as the latency of paw withdrawal to a radiant heat. Thermal hyperalgesia is defined as a decrease in the withdrawal latency compared to the basal measurement. After measuring basal level mice, under light halothane anesthesia (5%), are injected with testing compound into the left or right paws (5-10 μl intraplantar injection) and paw withdrawal measurements repeated at different time point. To assess PAR2 TRPV1, TRPV4 and TRPA1 mediated hyperalgesia and potentiation of TRPV-mediated responses, mice are treated with PAR2-AP for 15 minutes followed by capsaicin, 4αPDD or HNE. To assess the role of protein kinases, the antagonists or the corresponding vehicles are injected 20-30 minutes before the challenge with agonists. The effects induced by the different treatments are evaluated within the same rat comparing the responses recorded in the right paw (receiving for example saline, or vehicle) with the responses obtained in the left paw (receiving for example PAR2-AP or 4αPDD).
Formalin induced hyperalgesia is assessed using 5% solution of formalin administered by intradermal injection into the dorsal surface of the mouse or rat forepaw to induce a painful behavior. Pain is accessed on a four-level scale related to posture: 0, normal posture; 1, with the injected paw remaining on the ground but not supporting the animal; 2, with the injected paw clearly raised; and 3, with the injected paw being licked, nibbled, or shaken. Animals are observed and scored for behavior at 3 minutes after the injection (defined as initial phase that results from the direct stimulation of nociceptors), and then at 30-60 minutes after the injection (defined as second phase that involves a period of sensitization during which inflammatory phenomena occur). The nociceptive behavioral score for each 3-minutes interval is calculated as the weighted average of the number of seconds spent in each behavior. 2.5% solution of formalin is administered by intraplantar injection and thermal and mechanical pain measured as described above after 30-60 minutes. To assess the role of protein kinases, antagonists or their vehicles (control) are injected into the right paws 20-30 minutes before formalin. Nociceptive behavior will be scored for each rats and compared to control.
Compounds 1-156 were tested in a whole cell functional assay for PKC mediated IL-2 production as follows. Human primary T cell isolation and culture: Human primary T cells were prepared as follows. Whole blood was obtained from a healthy volunteer, mixed 1:1 with PBS, layered on to Ficoll Hypaque (Amersham Pharmacia Biotech, Piscataway, N.J., Catalog #17-1440-03) in 2:1 blood/PBS:ficoll ratio and centrifuged for 30 minutes at 4° C. at 1750 rpm. The cells at the serum: ficoll interface were recovered and washed twice with 5 volumes of PBS. These freshly isolated human peripheral blood mononuclear cells were cultured in Yssel's medium containing 40 U/ml IL2 in a flask pre-coated with 1 μg/ml aCD3 and 5 μg/ml aCD28 (Anti-Human CD3, BD Pharmingen Catalog #555336, Anti-Human CD28, Beckman Coulter Catalog #1M1376). The cells were stimulated for 3-4 days, then transferred to a fresh flask and maintained in RPMI (RPMI-1640 with L-Glutamine; Mediatech, Inc., Herndon Va., cat. #10-040-CM) with 10% FBS and 40 U/ml IL-2. The primary T-cells were then washed twice with PBS to remove the IL-2.
Primary T cell stimulation and IL2 ELISA: Human primary T cells (100,000 cells per well) were pre-incubated with or without test compound in Yssel's medium for 1 hour at 37° C. Cells were then stimulated by transferring them to round-bottom 96-well plates pre-coated with 1 μg/ml aCD3 and 5 μg/ml αCD28. For counter assay, cells were instead stimulated by adding 8× stock solutions of PMA and ionomycin in Yssels (for final concentrations of 0.5 ng/ml PMA and 0.1 uM ionomycin, both from Calbiochem). Cells were incubated at 37° C. for 24 hours before 100 μL supernatants were harvested for quantification of IL-2 by ELISA using Human IL-2 Duoset ELISA Kit from R and D Systems, Cat. #DY202E. Compounds 1-156 blocked IL-2 production with an IC50 of less than 30 micromolar.
IC50 data (micromolar) is shown in Table 5 below.
