## Title
Heteroaryl Btk inhibitors

## Abstract

The present invention provides compounds useful as inhibitors of Btk, compositions thereof, and methods of using the same.

## Background
The present application is a U.S. national phase application under 35 U.S.C. 371 of international patent application no. PCT/US2010/047879, filed Sep. 3, 2010, which claims priority to U.S. provisional application Ser. No. 61/240,003, filed Sep. 4, 2009, the entirety of each of which is hereby incorporated by reference.


BACKGROUND OF THE INVENTION
Protein kinases are a large multigene family consisting of more than 500 proteins which play a critical role in the development and treatment of a number of human diseases in oncology, neurology and immunology. The Tec kinases are non-receptor tyrosine kinases which consists of five members (Tec (tyrosine kinase expressed in hepatocellular carcinoma), Btk (Bruton's tyrosine kinase), Itk (interleukin-2 (IL-2)-inducible T-cell kinase; also known as Emt or Tsk), R1k (resting lymphocyte kinase; also known as Txk) and Bmx (bone-marrow tyrosine kinase gene on chromosome X; also known as Etk)) and are primarily expressed in haematopoietic cells, although expression of Bmx and Tec has been detected in endothelial and liver cells. Tec kinases (Itk, Rlk and Tec) are expressed in T cell and are all activated downstream of the T-cell receptor (TCR). Btk is a downstream mediator of B cell receptor (BCR) signaling which is involved in regulating B cell activation, proliferation, and differentiation. More specifically, Btk contains a PH domain that binds phosphatidylinositol (3,4,5)-trisphosphate (PIP3). PIP3 binding induces Btk to phosphorylate phospholipase C (PLCγ), which in turn hydrolyzes PIP2 to produce two secondary messengers, inositol triphosphate (IP3) and diacylglycerol (DAG), which activate protein kinase PKC, which then induces additional B-cell signaling. Mutations that disable Btk enzymatic activity result in XLA syndrome (X-linked agammaglobulinemia), a primary immunodeficiency. Given the critical roles which Tec kinases play in both B-cell and T-cell signaling, Tec kinases are targets of interest for autoimmune disorders.
Consequently, there is a great need in the art for effective inhibitors of Btk. The present invention fulfills these and other needs.

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.
In certain embodiments, the neutral forms of the compounds are regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner. In some embodiments, the parent form of the compound differs from the various salt forms in certain physical properties, such as solubility in polar solvents.
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.
The term “oxo,” as used herein, means an oxygen that is double bonded to a carbon atom, thereby forming a carbonyl.
One of ordinary skill in the art will appreciate that the synthetic methods, as described herein, utilize a variety of protecting groups. By the term “protecting group,” as used herein, it is meant that a particular functional moiety, e.g., O, S, or N, is masked or blocked, permitting, if desired, a reaction to be carried out selectively at another reactive site in a multifunctional compound. Suitable protecting groups are well known in the art and include those described in detail in Protecting Groups in Organic Synthesis, T. W. Greene and P. G. M. Wuts, 3rd edition, John Wiley & Sons, 1999, the entirety of which is incorporated herein by reference. In certain embodiments, a protecting group reacts selectively in good yield to give a protected substrate that is stable to the projected reactions; the protecting group is preferably selectively removable by readily available, preferably non-toxic reagents that do not attack the other functional groups; the protecting group forms a separable derivative (more preferably without the generation of new stereogenic centers); and the protecting group will preferably have a minimum of additional functionality to avoid further sites of reaction. As detailed herein, oxygen, sulfur, nitrogen, and carbon protecting groups may be utilized.

I. Exemplary Synthesis
Compounds of the invention are synthesized by an appropriate combination of generally well known synthetic methods. Techniques useful in synthesizing the compounds of the invention are both readily apparent and accessible to those of skill in the relevant art. The discussion below is offered to illustrate certain of the diverse methods available for use in assembling the compounds of the invention. However, the discussion is not intended to define the scope of reactions or reaction sequences that are useful in preparing the compounds of the present invention.
Compounds of formula (I) can be prepared according to Scheme 1 using commercially available or synthesized substituted amine protected heterocycles such as 3-(tert-Butoxycarbonylamino)pyrrolidine, 3-(tert-Butoxycarbonylamino)piperidine or 3-(tert-Butoxycarbonylamino)azepane (Huang, P.; Wang, S, Zheng, H,; Fei, X. Tetrahedron Lett. 1997, 38, 271. Hu, X. E.; Kim, N. K.; Ledoussal, B. Org. Lett. 2002, 4, 4499. Kitas, E. A.; Galley, G.; Jakob-Roetne, R.; Flohr, A.; Wostl, A.; Mauser, H.; Alker, A. M.; Czech, C.; Ozmen, L.; David-Pierson, P.; Reinhardt, D. Jacobsen, H. Bioorg. Med. Chem. Lett. 2008, 18, 304. Burgey, C. S.; Paone, D. V.; Shaw, A. W.; Nguyen, D. N.; Deng, Z. J.; Williams, T. M.; Vacca, J. P.; Selnick, H. G.; Potteiger, C. M. PCT Int. Appl. (2006), 292 pp. WO 2006044504). The heterocyclic amine can be protected using the appropriate protecting group familiar to those skilled in the art. The exo-cyclic amino group can be substituted upon treated with a base such as sodium hydride or by other bases (e.g., DIEA, Et3N, K2CO3, etc.) familiar to one skilled in the art and in a solvent such as DMF or other appropriate solvents to yield 1.3. The protected heterocyclic amine 1.4 can be de-protected to the amine which can be reacted with the substituted heteroaromatic such as pyridinyl and pyrimidyl moieties using DIEA or by other bases familiar to one skilled in the art and in a solvent such as DMF or another appropriate solvents to yield 1.6. Alternatively, the N-amination can be accomplished utilizing Buchwald coupling (Shafir, A. Buchwald, S. L. J. Am. Chem. Soc. 2006, 128, 8742. Mehrotra, M. M. et. al. Bioorganic & Medicinal Chemistry Letters 2002, 12, 1103). The exo-cyclic amine protecting group can be removed upon treatment with suitable conditions as described in Greene and Wuts, Protective Group in Organic Synthesis, 3rd edition, John Wiley & Sons, New York. The amine 1.7 can be reacted with the appropriate electrophile such as a substituted acid chloride, sulfonyl chloride, alkyl halide or carboxylic acid which can be activated using standard peptide coupling reagents such as EDCI/HOBt, PyBOP, HATU or BEM (Carpino, L. A. J. Am. Chem. Soc. 1993, 115, 4397. Carpino, L. A.; El-Faham, A. J. Am. Chem. Soc. 1995, 117, 5401. Li, P.; Xu, J. C. J. Pept. Res. 2001, 58, 129.) in the presence of a base such as DIEA or other bases familiar to one skilled in the art and in an appropriate solvent to yield 1.8. Alternatively and/or additionally, the exo-cyclic amine 1.7 can be reacted with chloroformate or chlorothioformate or o-, p-nitrophenylchloroformate or phenylchloroformate (or their thiocarbonyl equivalents), or diphenyl cyanocarbonimidate followed by displacement with the appropriate amine can also yield the corresponding urea, thiourea or cyanoguanidine. When synthesizing compounds containing the 1H-pyrazolo[3,4-d]pyrimidine moiety or other compounds reported within this invention which contain functional groups that are not compatible with electrophilic substitution, it will be necessary to do an additional step to remove the protecting group to afford compound I.
The groups “Lg”, “Lg1”, and “Lg2” in Schemes 1-3 are suitable leaving groups, i.e., groups that are subject to nucleophilic displacement. A “suitable leaving group” is a chemical group that is readily displaced by a desired incoming chemical moiety such as an amine. Suitable leaving groups are well known in the art, e.g., see, “Advanced Organic Chemistry,” Jerry March, 5th Ed., pp. 351-357, John Wiley and Sons, N.Y. Such leaving groups include, but are not limited to, halogen, alkoxy, sulphonyloxy, optionally substituted alkylsulphonyloxy, optionally substituted alkenylsulfonyloxy, optionally substituted arylsulfonyloxy, acyl, and diazonium moieties. Examples of suitable leaving groups include chloro, iodo, bromo, fluoro, acetoxy, methoxy, methanesulfonyloxy (mesyloxy), tosyloxy, triflyloxy, nitro-phenylsulfonyloxy (nosyloxy), and bromo-phenylsulfonyloxy (brosyloxy).
The groups “Pg”, “Pg1”, and “Pg2” in Schemes 1-4 are suitable protecting groups, as defined above and described herein. One of ordinary skill will be familiar with a variety of protecting group and protecting group strategies that many be employed in the Schemes depicted below.




Alternatively and/or additionally, certain compounds of formula (I) can also be prepared according to Scheme 2 using commercially available substituted heterocycles such as pyrrolidine, piperidine or azepanes which can undergo N-animation with substituted heteroaromatic such as pyridinyl and pyrimidyl moities using DIEA or by other bases familiar to one skilled in the art and in a solvent such as DMF or another appropriate solvents to yield 2.3. The N-amination can also be accomplished utilizing Buchwald coupling (Shafir, A. Buchwald, S. L. J. Am. Chem. Soc. 2006, 128, 8742. Mehrotra, M. M. et. al. Bioorganic & Medicinal Chemistry Letters 2002, 12, 1103) to afford 2.3. The exo-cyclic amine protecting group can be removed upon treatment with suitable conditions as described in Greene and Wuts, Protective Group in Organic Synthesis, 3rd edition, John Wiley & Sons, New York to give compound 2.4. The amine can be substituted using the appropriate electrophile such as 2-chloroacetyl chloride in the presence of an organic base such as triethylamine or other suitable bases familiar to those skilled in the art and in a solvent such as dichloromethane or another appropriate solvent. Compound 2.5 can undergo nucleophilic displacement with various nucleophiles such as primary and secondary amines to yield compounds represented by structure 2.6. When synthesizing compounds containing the 1H-pyrazolo[3,4-d]pyrimidine moiety or other compounds reported within this invention which contain functional groups that are not compatible with electrophilic substitution it may be necessary to do an additional step to remove the protecting group to afford compound of formula V.




Compounds of formula (I) can be prepared via intermediates 2.4 which can be reacted with the appropriate electrophile such as a substituted or unsubstituted glycyl carboxamide as shown in Scheme 3. The protected amine compound 3.1 can be de-protected upon treatment with suitable conditions as described in Greene and Wuts, Protective Group in Organic Synthesis, 3rd edition, John Wiley & Sons, New York. The amine 3.2 can be reacted with the appropriate electrophile such as a substituted acid chloride, sulfonyl chloride, alkyl halide or carboxylic acid which can be activated using standard peptide coupling reagents such as EDCI/HOBt, PyBOP, HATU or BEM (Carpino, L. A. J. Am. Chem. Soc. 1993, 115, 4397. Carpino, L. A.; El-Faham, A. J. Am. Chem. Soc. 1995, 117, 5401. Li, P.; Xu, J. C. J. Pept. Res. 2001, 58, 129.) in the presence of an organic base such as DIEA or other bases familiar to one skilled in the art and in an appropriate solvent to yield 3.3. When synthesizing compounds containing the 1H-pyrazolo[3,4-d]pyrimidine moiety or other compounds reported herein containing functional groups that are not compatible with electrophilic substitution it will be necessary to do an additional step to remove the protecting group to afford compound IV-d.




Compounds of formula (I) wherein R3 and R4 join together to form a heteroaryl (e.g. pyrazolo) can be prepared according to Scheme 4 using commercially available 4,6-dihydroxypyrimidine 4.1. The 4,6-dihydroxyprimidine can be chlorinated and formylation under Vilsmeier conditions upon treatment with POCl3 and DMF to afford the 5-formyl-6,3-dichloro-5-formylpyrimidine 4.2. The aldehyde 4.2 can be condensed with the hydrazine to afford the imine which can undergo intramolecular cyclization to give 4.3. The 4-chloro-1H-pyrazolo[3,4-d]pyrimidine intermediate can be protected upon treatment with suitable conditions as described in Greene and Wuts, Protective Group in Organic Synthesis, 3rd edition, John Wiley & Sons, New York to afford 4.4 and can then undergo N-amination upon treatment with a substituted heterocyclic amine in the presence of DIEA or by other bases familiar to one skilled in the art and in a solvent such as DMF or another appropriate solvent. The final step is the removal of the protecting group using suitable conditions to afford compounds of formula VIII-a.




In certain embodiments, each of the aforementioned synthetic steps of Schemes 1-4 may be performed sequentially with isolation of each intermediate performed after each step. Alternatively, each of the steps as depicted in Schemes 1-4 above, may be performed in a manner whereby no isolation of each intermediate is performed. Furthermore, it will be readily apparent to the skilled artisan that additional steps may be performed to accomplish particular protection group and/or deprotection strategies.

Assays
To develop useful Btk inhibitors, candidate inhibitors capable of decreasing Btk enzymatic activity may be identified in vitro. The activity of the inhibitor compounds can be assayed utilizing methods known in the art and/or those methods presented herein.
Compounds that decrease Btk enzymatic activity may be identified and tested using biologically active Btk, either recombinant or naturally occurring. Btk can be found in native cells, isolated in vitro, or co-expressed or expressed in a cell. Measuring the reduction in the Btk enzymatic activity in the presence of an inhibitor relative to the activity in the absence of the inhibitor may be performed using a variety of methods known in the art, such as the BTK-POLYGAT-LS ASSAY described below in the Examples. Other methods for assaying the activity of Btk are known in the art. The selection of appropriate assay methods is well within the capabilities of those of skill in the art.
Once compounds are identified that are capable of reducing Btk enzymatic activity, the compounds may be further tested for their ability to selectively inhibit Btk relative to other enzymes. Inhibition by a compound of the invention is measured using standard in vitro or in vivo assays such as those well known in the art or as otherwise described herein.
Compounds may be further tested in cell models or animal models for their ability to cause a detectable changes in phenotype related to Btk activity. In addition to cell cultures, animal models may be used to test Btk inhibitors for their ability to treat autoimmune disorders, inflammatory disorders, or cancer in an animal model.
Pharmaceutical Compositions
In another aspect, the present invention provides pharmaceutical compositions comprising a Btk inhibitor compound of the invention or a Btk inhibitor compound in combination with a pharmaceutically acceptable excipient (e.g., carrier).
The pharmaceutical compositions include optical isomers, diastereomers, or pharmaceutically acceptable salts of the inhibitors disclosed herein. For example, in some embodiments, the pharmaceutical compositions include a compound of the present invention and citrate as a pharmaceutically acceptable salt. The Btk inhibitor included in the pharmaceutical composition may be covalently attached to a carrier moiety, as described above. Alternatively, the Btk inhibitor included in the pharmaceutical composition is not covalently linked to a carrier moiety.
A “pharmaceutically acceptable carrier,” as used herein refers to pharmaceutical excipients, for example, pharmaceutically, physiologically, acceptable organic or inorganic carrier substances suitable for enteral or parenteral application that do not deleteriously react with the active agent. Suitable pharmaceutically acceptable carriers include water, salt solutions (such as Ringer's solution), alcohols, oils, gelatins, and carbohydrates such as lactose, amylose or starch, fatty acid esters, hydroxymethycellulose, and polyvinyl pyrrolidine. Such preparations can be sterilized and, if desired, mixed with auxiliary agents such as lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, and/or aromatic substances and the like that do not deleteriously react with the compounds of the invention.
The compounds of the invention can be administered alone or can be coadministered to a subject. Coadministration is meant to include simultaneous or sequential administration of the compounds individually or in combination (more than one compound). The preparations can also be combined, when desired, with other active substances (e.g. to reduce metabolic degradation).
Formulations
Compounds of the present invention can be prepared and administered in a wide variety of oral, parenteral, and topical dosage forms. Thus, the compounds of the present invention can be administered by injection (e.g. intravenously, intramuscularly, intracutaneously, subcutaneously, intraduodenally, or intraperitoneally). Also, the compounds described herein can be administered by inhalation, for example, intranasally. Additionally, the compounds of the present invention can be administered transdermally. It is also envisioned that multiple routes of administration (e.g., intramuscular, oral, transdermal) can be used to administer the compounds of the invention. Accordingly, the present invention also provides pharmaceutical compositions comprising a pharmaceutically acceptable carrier or excipient and one or more compounds of the invention.
For preparing pharmaceutical compositions from the compounds of the present invention, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier can be one or more substances that may also act as diluents, flavoring agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material.
In powders, the carrier is a finely divided solid in a mixture with the finely divided active component. In tablets, the active component is mixed with the carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired.
The powders and tablets preferably contain from 5% to 70% of the active compound. Suitable carriers are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter, and the like. The term “preparation” is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component with or without other carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid dosage forms suitable for oral administration.
For preparing suppositories, a low melting wax, such as a mixture of fatty acid glycerides or cocoa butter, is first melted and the active component is dispersed homogeneously therein, as by stirring. The molten homogeneous mixture is then poured into convenient sized molds, allowed to cool, and thereby to solidify.
Liquid form preparations include solutions, suspensions, and emulsions, for example, water or water/propylene glycol solutions. For parenteral injection, liquid preparations can be formulated in solution in aqueous polyethylene glycol solution.
When parenteral application is needed or desired, particularly suitable admixtures for the compounds of the invention are injectable, sterile solutions, preferably oily or aqueous solutions, as well as suspensions, emulsions, or implants, including suppositories. In particular, carriers for parenteral administration include aqueous solutions of dextrose, saline, pure water, ethanol, glycerol, propylene glycol, peanut oil, sesame oil, polyoxyethylene-block polymers, and the like. Ampoules are convenient unit dosages. The compounds of the invention can also be incorporated into liposomes or administered via transdermal pumps or patches. Pharmaceutical admixtures suitable for use in the present invention include those described, for example, in Pharmaceutical Sciences (17th Ed., Mack Pub. Co., Easton, Pa.) and WO 96/05309, the teachings of both of which are hereby incorporated by reference.
Aqueous solutions suitable for oral use can be prepared by dissolving the active component in water and adding suitable colorants, flavors, stabilizers, and thickening agents as desired. Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, and other well-known suspending agents.
Also included are solid form preparations that are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active component, colorants, flavors, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like.
The pharmaceutical preparation is preferably in unit dosage form. In such form the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packeted tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form.
The quantity of active component in a unit dose preparation may be varied or adjusted from 0.1 mg to 10000 mg, more typically 1.0 mg to 1000 mg, most typically 10 mg to 500 mg, according to the particular application and the potency of the active component. The composition can, if desired, also contain other compatible therapeutic agents.
Some compounds may have limited solubility in water and therefore may require a surfactant or other appropriate co-solvent in the composition. Such co-solvents include: Polysorbate 20, 60, and 80; Pluronic F-68, F-84, and P-103; cyclodextrin; and polyoxyl 35 castor oil. Such co-solvents are typically employed at a level between about 0.01% and about 2% by weight.
Viscosity greater than that of simple aqueous solutions may be desirable to decrease variability in dispensing the formulations, to decrease physical separation of components of a suspension or emulsion of formulation, and/or otherwise to improve the formulation. Such viscosity building agents include, for example, polyvinyl alcohol, polyvinyl pyrrolidone, methyl cellulose, hydroxy propyl methylcellulose, hydroxyethyl cellulose, carboxymethyl cellulose, hydroxy propyl cellulose, chondroitin sulfate and salts thereof, hyaluronic acid and salts thereof, and combinations of the foregoing. Such agents are typically employed at a level between about 0.01% and about 2% by weight.
The compositions of the present invention may additionally include components to provide sustained release and/or comfort. Such components include high molecular weight, anionic mucomimetic polymers, gelling polysaccharides, and finely-divided drug carrier substrates. These components are discussed in greater detail in U.S. Pat. Nos. 4,911,920; 5,403,841; 5,212,162; and 4,861,760. The entire contents of these patents are incorporated herein by reference in their entirety for all purposes.
Effective Dosages
Pharmaceutical compositions provided by the present invention include compositions wherein the active ingredient is contained in a therapeutically effective amount, i.e., in an amount effective to achieve its intended purpose. The actual amount effective for a particular application will depend, inter alia, on the condition being treated. For example, when administered in methods to treat cancer, such compositions will contain an amount of active ingredient effective to achieve the desired result (e.g. decreasing the number of cancer cells in a subject).
The dosage and frequency (single or multiple doses) of compound administered can vary depending upon a variety of factors, including route of administration; size, age, sex, health, body weight, body mass index, and diet of the recipient; nature and extent of symptoms of the disease being treated (e.g., the disease responsive to Btk inhibition); presence of other diseases or other health-related problems; kind of concurrent treatment; and complications from any disease or treatment regimen. Other therapeutic regimens or agents can be used in conjunction with the methods and compounds of the invention.
For any compound described herein, the therapeutically effective amount can be initially determined from cell culture assays. Target concentrations will be those concentrations of active compound(s) that are capable of decreasing Btk enzymatic activity as measured, for example, using the methods described.
Therapeutically effective amounts for use in humans may be determined from animal models. For example, a dose for humans can be formulated to achieve a concentration that has been found to be effective in animals. The dosage in humans can be adjusted by monitoring Btk inhibition and adjusting the dosage upwards or downwards, as described above.
Dosages may be varied depending upon the requirements of the patient and the compound being employed. The dose administered to a patient, in the context of the present invention, should be sufficient to effect a beneficial therapeutic response in the patient over time. The size of the dose also will be determined by the existence, nature, and extent of any adverse side effects. Generally, treatment is initiated with smaller dosages, which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under circumstances is reached. In some embodiments, the dosage range is 0.001% to 10% w/v. In some embodiments, the dosage range is 0.1% to 5% w/v.
Dosage amounts and intervals can be adjusted individually to provide levels of the administered compound effective for the particular clinical indication being treated. This will provide a therapeutic regimen that is commensurate with the severity of the individual's disease state.

Example 161
In vitro BTK kinase assay: BTK-POLYGAT-LS ASSAY. The purpose of the BTK in vitro assay is to determine compound potency against BTK through the measurement of IC50. Compound inhibition is measured after monitoring the amount of phosphorylation of a fluorescein-labeled polyGAT peptide (Invitrogen PV3611) in the presence of active BTK enzyme (Upstate 14-552), ATP, and inhibitor. The BTK kinase reaction was done in a black 96 well plate (costar 3694). A 24 μL aliquot of a ATP/peptide master mix (final concentration; ATP 10 μM, polyGAT 100 nM) in kinase buffer (10 mM Tris-HCl pH 7.5, 10 mM MgCl2, 200 μM Na3VO4, 5 mM DTT, 0.01% Triton X-100, and 0.2 mg/ml Casein) is added to each well. Next, 1 μL of a 4-fold, 40× compound titration in 100% DMSO solvent is added, followed by adding 15 μL of BTK enzyme mix in 1× kinase buffer (with a final concentration of 0.25 nM). The assay is incubated for 30 minutes before being stopped with 28 μL of a 50 mM EDTA solution. Five μL of the kinase reaction is transferred to a low volume white 384 well plate (Corning 3674) and 5 μL of a 2× detection buffer (Invitrogen PV3574, with 4 nM Tb-PY20 antibody, Invitrogen PV3552) is added. The plate is covered and incubated for 45 minutes at room temperature. Time resolved fluorescence (TRF) on Molecular Devices M5 (332 nm excitation; 488 nm emission; 518 nm fluorescein emission) is measured. IC50 values are calculated using a four parameter fit with 100% enzyme activity determined from the DMSO control and 0% activity from the EDTA control.
Example 162
Protocol for Human B Cell Stimulation
Human B cells were purified from 150 ml of blood. Briefly, the blood was diluted 1⁄2 with PBS and centrifuged through a Ficoll density gradient. The B cells were isolated from the mononuclear cells by negative selection using the B cell isolation kit II from Milenyi (Auburn, Calif.). 50,000 B cells per well were then stimulated with 10 μg/ml of goat F(ab′)2 anti-human IgM antibodies (Jackson ImmunoResearch Laboratories, West Grove, Pa.) in a 96-well plate. Compounds were diluted in DMSO and added to the cells. Final concentration of DMSO was 0.5%. Proliferation was measured after 3 days using Promega CellTiter-Glo® (Madison, Wis.). Certain compounds of formula I were tested and found to be active.
Table 1 shows the activity of selected compounds of this invention in the in vitro Btk kinase assay. Compounds have an activity designated as “A” provided an IC50<100 nM; compounds having an activity designated as “B” provided an IC50 of 100-999 nM; compounds having an activity designated as “C” provided an IC50 of 1000-10,000 nM; and compounds having an activity designated as “D” provided an IC50 of >10,000 nM. In some instances where a compound tested has activity “D”, other structurally similar compounds beyond the measurable limits of the assay are not included in Table 1.
