     BACKGROUND OF THE INVENTION 
     Bruton tyrosine kinase (Btk) is a Tec family non-receptor protein kinase, expressed in most hematopoietic cells such as B cells, mast cells, and macrophages but not in T cells, natural killer cells, and plasma cells [Smith, C. I. et al. Journal of Immunology (1994), 152 (2), 557-65]. Btk is a crucial part of the BCR and FcR signaling pathway, and the targeted inhibition of Btk is a novel approach for treating many different human diseases such as B-cell malignancies, autoimmune disease, and inflammatory disorders [Uckun, Fatih M. et al, Anti-Cancer Agents in Medicinal Chemistry (2007), Shinohara et al, Cell 132 (2008) pp 794-806; Pan, Zhengying, Drug News &amp; Perspectives (2008), 21 (7); 7 (6), 624-632; Gilfillan et al, Immunological Reviews 288 (2009) pp 149-169; Davis et al, Nature, 463 (2010) pp 88-94]. 
     Covalent Bruton&#39;s tyrosine kinase (BTK) inhibitors including ibrutinib and acalabrutinib have transformed the treatment landscape of several BTK dependent B-cell malignancies, including chronic lymphocytic leukemia, Waldenstrom&#39;s macroglobulinemia, mantle cell lymphoma and marginal zone lymphoma. Despite impressive clinical response of ibrutinib in B-cell malignancies, cases of primary and secondary resistance have emerged with poor outcomes and limited treatment options. The majority of CLL patients who become resistant to irreversible BTK inhibitors such as ibrutinib develop the BTK-C481S mutation. It was reported that 80% of patients relapsing CLL will have the C481S mutation [Maddocks K J, et al. JAMA Oncol. 2015; 1:80-87]. Another research group in the Ohio State University reported in  Journal of Clinical Oncology  [Vol 35, number 13, 2017, page 1437] that at year four, roughly 20% of patients on ibrutinib clinically progressed. Of these patients who relapsed, 85% had acquired the C481S mutation. Additionally, these mutations were detected, on average, over nine months before a relapse. 
     Although BTK inhibitors such as Ibrutinib, and ACP-196, have made a significant contribution to the art, there is a strong need for continuing search in this field of art for highly potent and selective BTK inhibitors that can not only irreversibly inhibiting WT BTK but also reversibly inhibiting C481S mutant BTK. 
     SUMMARY OF THE INVENTION 
     The present invention relates to a class of potent and selective Btk inhibitors which are rationally designed to not only irreversibly inhibit the WT BTK but also reversibly inhibit the C481S mutant BTK. Thus, the compounds of the present invention may be useful in treating the patients resistant/refractory to the first generation BTK inhibitors such as Ibrutinib and ACP-196 (Acalabrutinib), particularly with BTK C481S mutation. The compounds of the present invention may be useful in treating the patients with diseases such as autoimmune disease, or inflammatory disorders.

  

     Compounds of the invention may contain one or more asymmetric carbon atoms. Accordingly, the compounds may exist as diastereomers, enantiomers or mixtures thereof. The syntheses of the compounds may employ racemates, diastereomers or enantiomers as starting materials or as intermediates. Diastereomeric compounds may be separated by chromatographic or crystallization methods. Similarly, enantiomeric mixtures may be separated using the same techniques or others known in the art. Each of the asymmetric carbon atoms may be in the R or S configuration and both of these configurations are within the scope of the invention. 
     A modified compound of any one of such compounds including a modification having an improved (e.g., enhanced, greater) pharmaceutical solubility, stability, bioavailability and/or therapeutic index as compared to the unmodified compound is also contemplated. The examples of modifications include but not limited to the prodrug derivatives, and the deuterium-enriched compounds. For example:
         Prodrug derivatives: prodrugs, upon administration to a subject, will converted in vivo into active compounds of the present invention [ Nature Reviews of Drug Discovery,  2008, Volume 7, p 255]. It is noted that in many instances, the prodrugs themselves also fall within the scope of the range of compounds according to the present invention. The prodrugs of the compounds of the present invention can be prepared by standard organic reaction, for example, by reacting with a carbamylating agent (e.g., 1,1-acyloxyalkylcarbonochloridate, para-nitrophenyl carbonate, or the like) or an acylating agent. Further examples of methods and strategies of making prodrugs are described in  Bioorganic and Medicinal Chemistry Letters,  1994, Vol. 4, p. 1985.   Deuterium-enriched compounds: deuterium (D or  2 H) is a stable, non-radioactive isotope of hydrogen and has an atomic weight of 2.0144. Hydrogen naturally occurs as a mixture of the isotopes  X H (hydrogen or protium), D ( 2 H or deuterium), and T (3H or tritium). The natural abundance of deuterium is 0.015%. One of ordinary skill in the art recognizes that in all chemical compounds with a H atom, the H atom actually represents a mixture of H and D, with about 0.015% being D. Thus, compounds with a level of deuterium that has been enriched to be greater than its natural abundance of 0.015%, should be considered unnatural and, as a result, novel over their nonenriched counterparts.       

     It should be recognized that the compounds of the present invention may be present and optionally administered in the form of salts, and solvates. For example, it is within the scope of the present invention to convert the compounds of the present invention into and use them in the form of their pharmaceutically acceptable salts derived from various organic and inorganic acids and bases in accordance with procedures well known in the art. 
     When the compounds of the present invention possess a free base form, the compounds can be prepared as a pharmaceutically acceptable acid addition salt by reacting the free base form of the compound with a pharmaceutically acceptable inorganic or organic acid, e.g., hydrohalides such as hydrochloride, hydrobromide, hydroiodide; other mineral acids such as sulfate, nitrate, phosphate, etc.; and alkyl and monoarylsulfonates such as ethanesulfonate, toluenesulfonate and benzenesulfonate; and other organic acids and their corresponding salts such as acetate, tartrate, maleate, succinate, citrate, benzoate, salicylate and ascorbate. Further acid addition salts of the present invention include, but are not limited to: adipate, alginate, arginate, aspartate, bisulfate, bisulfite, bromide, butyrate, camphorate, camphorsulfonate, caprylate, chloride, chlorobenzoate, cyclopentanepropionate, digluconate, dihydrogenphosphate, dinitrobenzoate, dodecylsulfate, fumarate, galacterate (from mucic acid), galacturonate, glucoheptaoate, gluconate, glutamate, glycerophosphate, hemisuccinate, hemisulfate, heptanoate, hexanoate, hippurate, 2-hydroxyethanesulfonate, iodide, isethionate, iso-butyrate, lactate, lactobionate, malonate, mandelate, metaphosphate, methanesulfonate, methylbenzoate, monohydrogenphosphate, 2-naphthalenesulfonate, nicotinate, oxalate, oleate, pamoate, pectinate, persulfate, phenylacetate, 3-phenylpropionate, phosphonate and phthalate. It should be recognized that the free base forms will typically differ from their respective salt forms somewhat in physical properties such as solubility in polar solvents, but otherwise the salts are equivalent to their respective free base forms for the purposes of the present invention. 
     When the compounds of the present invention possess a free acid form, a pharmaceutically acceptable base addition salt can be prepared by reacting the free acid form of the compound with a pharmaceutically acceptable inorganic or organic base. Examples of such bases are alkali metal hydroxides including potassium, sodium and lithium hydroxides; alkaline earth metal hydroxides such as barium and calcium hydroxides; alkali metal alkoxides, e.g., potassium ethanolate and sodium propanolate; and various organic bases such as ammonium hydroxide, piperidine, diethanolamine and N-methylglutamine.

It should be recognized that the free acid forms will typically differ from their respective salt forms somewhat in physical properties such as solubility in polar solvents, but otherwise the salts are equivalent to their respective free acid forms for the purposes of the present invention. 
     In one aspect, a pharmaceutically acceptable salt is a hydrochloride salt, hydrobromide salt, methanesulfonate, toluenesulfonate, acetate, fumarate, sulfate, bisulfate, succinate, citrate, phosphate, maleate, nitrate, tartrate, benzoate, biocarbonate, carbonate, sodium hydroxide salt, calcium hydroxide salt, potassium hydroxide salt, tromethamine salt, or mixtures thereof.

Such salts permit the preparation of both water- and oil-soluble compounds of the invention. 
     Amine oxides, also known as amine-N-oxide and N-oxide, of anti-cancer agents with tertiary nitrogen atoms have been developed as prodrugs [Mol Cancer Therapy. 2004 March; 3(3):233-44]. Compounds of the present invention that comprise tertiary nitrogen atoms may be oxidized by such agents as hydrogen peroxide (H 2 O 2 ), Caro&#39;s acid or peracids like meta-Chloroperoxybenzoic acid (mCPBA) to from amine oxide.

Exemplary salts include, but are not limited, to sulfate, citrate, acetate, oxalate, chloride, bromide, iodide, nitrate, bisulfate, phosphate, acid phosphate, isonicotinate, lactate, salicylate, acid citrate, tartrate, oleate, tannate, pantothenate, bitartrate, ascorbate, succinate, maleate, gentisinate, fumarate, gluconate, glucuronate, saccharate, formate, benzoate, glutamate, methanesulfonate “mesylate,” ethanesulfonate, benzenesulfonate, p-toluenesulfonate, pamoate (i.e., 1,1′-methylene-bis-(2-hydroxy-3-naphthoate)) salts, alkali metal (e.g., sodium and potassium) salts, alkaline earth metal (e.g., magnesium) salts, and ammonium salts. A pharmaceutically acceptable salt may involve the inclusion of another molecule such as an acetate ion, a succinate ion or other counter ion. The counter ion may be any organic or inorganic moiety that stabilizes the charge on the parent compound. Furthermore, a pharmaceutically acceptable salt may have more than one charged atom in its structure. Instances where multiple charged atoms are part of the pharmaceutically acceptable salt can have multiple counter ions. Hence, a pharmaceutically acceptable salt can have one or more charged atoms and/or one or more counter ion. 
     “Pharmaceutically acceptable carrier” means a non-toxic solvent, dispersant, excipient, adjuvant, or other material which is mixed with the compounds of the present invention in order to form a pharmaceutical composition, i.e., a dose form capable of administration to the patient.

     “Pharmacophore,” as defined by The International Union of Pure and Applied Chemistry, is an ensemble of steric and electronic features that is necessary to ensure the optimal supramolecular interactions with a specific biological target and to trigger (or block) its biological response. For example, Camptothecin is the pharmacophore of the well known drug topotecan and irinotecan. Mechlorethamine is the pharmacophore of a list of widely used nitrogen mustard drugs like Melphalan, Cyclophosphamide, Bendamustine, and so on. 
     “Prodrug” means a compound that is convertible in vivo metabolically into an active pharmaceutical according to the present invention. For example, an inhibitor comprising a hydroxyl group may be administered as an ester that is converted by hydrolysis in vivo to the hydroxyl compound. 
     “Stability” in general refers to the length of time a drug retains its properties without loss of potency. Sometimes this is referred to as shelf life. Factors affecting drug stability include, among other things, the chemical structure of the drug, impurity in the formulation, pH, moisture content, as well as environmental factors such as temperature, oxidization, light, and relative humidity. Stability can be improved by providing suitable chemical and/or crystal modifications (e.g., surface modifications that can change hydration kinetics; different crystals that can have different properties), excipients (e.g., anything other than the active substance in the dosage form), packaging conditions, storage conditions, etc. 
     “Therapeutically effective amount” of a composition described herein is meant an amount of the composition which confers a therapeutic effect on the treated subject, at a reasonable benefit/risk ratio applicable to any medical treatment. The therapeutic effect may be objective (i.e., measurable by some test or marker) or subjective (i.e., subject gives an indication of or feels an effect). An effective amount of the composition described above may range from about 0.1 mg/kg to about 500 mg/kg, preferably from about 0.2 to about 50 mg/kg. Effective doses will also vary depending on route of administration, as well as the possibility of co-usage with other agents. It will be understood, however, that the total daily usage of the compositions of the present invention will be decided by the attending physician within the scope of sound medical judgment. The specific therapeutically effective dose level for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or contemporaneously with the specific compound employed; and like factors well known in the medical arts. 
     As used herein, the term “treating” refers to administering a compound to a subject that has a neoplastic or immune disorder, or has a symptom of or a predisposition toward it, with the purpose to cure, heal, alleviate, relieve, alter, remedy, ameliorate, improve, or affect the disorder, the symptoms of or the predisposition toward the disorder. The term “an effective amount” refers to the amount of the active agent that is required to confer the intended therapeutic effect in the subject. Effective amounts may vary, as recognized by those skilled in the art, depending on route of administration, excipient usage, and the possibility of co-usage with other agents. 
     A “subject” refers to a human and a non-human animal. Examples of a non-human animal include all vertebrates, e.g., mammals, such as non-human primates (particularly higher primates), dog, rodent (e.g., mouse or rat), guinea pig, cat, and non-mammals, such as birds, amphibians, reptiles, etc. In a preferred embodiment, the subject is a human.

     In Scheme A, the appropriate starting material 1 can react with 2 to form the intermediate 3, which can be converted to 4 by standard organic reaction with high yield. Meanwhile, the intermediate 5 can be obtained by the reaction of the commercially available 3,5-dibromo-1-methylpyrazin-2(1H)-one (CAS 87486-34-8) with appropriate 4-substituted 3-nitroaniline. Then, the coupling reaction of 4 with 5 will yield the nitro intermediate 6, which can be reduced to the amine intermediate 7. Finally, 7 can be reduced to the alcohol intermediate 8, which can react appropriate acryloyl chloride to afford Formula (IV).

     Biological Example 1: Binding Constant (K d ) Determination 
     The K d  of the compounds were determined by KINOMEscan™ assay, the industry&#39;s most comprehensive high-throughput system for screening compounds against large numbers of human kinases. KINOMEscan™ assay is based on a competition binding assay that quantitatively measures the ability of a compound to compete with an immobilized, active-site directed ligand. The assay is performed by combining three components: DNA-tagged kinase; immobilized ligand; and a test compound. The ability of the test compound to compete with the immobilized ligand is measured via quantitative PCR of the DNA tag. The kinase-tagged T7 phage strains were prepared in an  E. coli  host derived from the BL21 strain.  E. coli  were grown to log-phase and infected with T7 phage and incubated with shaking at 32° C. until lysis. The lysates were centrifuged and filtered to remove cell debris. The remaining kinases were produced in HEK-293 cells and subsequently tagged with DNA for qPCR detection. Streptavidin-coated magnetic beads were treated with biotinylated small molecule ligands for 30 minutes at room temperature to generate affinity resins for kinase assays. The liganded beads were blocked with excess biotin and washed with blocking buffer (SeaBlock (Pierce), 1% BSA, 0.05% Tween 20, 1 mM DTT) to remove unbound ligand and to reduce non-specific binding. Binding reactions were assembled by combining kinases, liganded affinity beads, and test compounds in 1×binding buffer (20% SeaBlock, 0.17×PBS, 0.05% Tween 20, 6 mM DTT). All reactions were performed in polystyrene 96-well plates in a final volume of 0.135 ml. The assay plates were incubated at room temperature with shaking for 1 hour and the affinity beads were washed with wash buffer (1×PBS, 0.05% Tween 20). The beads were then re-suspended in elution buffer (1×PBS, 0.05% Tween 20, 0.5 μM nonbiotinylated affinity ligand) and incubated at room temperature with shaking for 30 minutes. The kinase concentration in the eluates was measured by qPCR. An 11-point 3-fold serial dilution of each test compound was prepared in 100% DMSO at 100×final test concentration and subsequently diluted to 1× in the assay (final DMSO concentration=1%). Most K d  were determined using a compound top concentration=30,000 nM. If the initial K d  determined was &lt;0.5 nM (the lowest concentration tested), the measurement was repeated with a serial dilution starting at a lower top concentration. A K d  value reported as 40,000 nM indicates that the K d  was determined to be &gt;30,000 nM. Binding constants (K d s) were calculated with a standard dose-response curve using the Hill equation: Response=Background+(Signal−Background)/[1+(K d   Hill Slope /Dose Hill Slope )]. The Hill Slope was set to −1. Curves were fitted using a non-linear least square fit with the Levenberg-Marquardt algorithm. Such assays, carried out with a range of doses of test compounds, allow the determination of an approximate K d  value. Although the K d  of the compounds of the present invention vary with structural change as expected, the activity generally exhibited by these agents is in the range of K d =0.1-1000 nM. 
     Biological Example 2: In Vitro Dialysis Assay (Irreversibility Assay) 
     IC50 of the test compound, was determined in the presence of 0.1 nM Enzyme and 40 mM ATP. 0.003 mM Compound (39×IC50 @40 mM ATP) was pre-incubated with 2 nM BTK for 2 hr in assay buffer without ATP. The compound-enzyme complex was dialyzed against the same buffer supplemented with 40 mM ATP for 24 hr. Cumulative dialysis factor &gt;160,000×. After dialysis, the BTK activity was measured in the presence 40 mM ATP and 1 mM substrate peptide and compared to that in non-dialyzed samples. Assay buffer: 100 mM HEPES, pH7.5; 0.1% BSA, 0.01% Triton-X 100; 5 mM MgCl 2 ; 1 mM DTT. In this study, Ibrutinib (a FDA approved irreversible BTK inhibitor) was used as a positive control and Saurosporine (a reversible BTK inhibitor) was used as a negative control. The following table shows the recovery after 24 hr dialysis. 
     In this assay, GDC-0853, a reversible BTK inhibitor, was used as a reference compound. GDC-0853, disclosure in WO 2013067274, is an orally bioavailable, selective, and reversible Bruton&#39;s tyrosine kinase (BTK) inhibitor with IC50s ranging from 2-9 nM for basophil activation, B cell receptor activation, and constitutive p-BTK activity in whole blood lysates.1,2 In rats, treatment for longer than 7 days leads to pancreatic toxicity but it does not occur in mice or dogs, even at higher doses. Formulations containing GDC-0853 were well-tolerated in Phase I clinical trials and are in additional clinical trials for rheumatoid arthritis, lupus erythematosus and other autoimmune diseases. 
     The data of the WT BTK dialysis assay clearly shows that Ibrutnib, Example 2, Example 3, Example 11, Example 12 are irreversible inhibitors of WT BTK, while GDC-0853 is a reversible WT BTK inhibitor.

     For the C481S BTK enzyme, Ibrutinib, and our compounds such as Example 2 reversiblly bind to the C481S BTK since the Cysteine residue is not available any more for covalent binding. 
     Biological Example 3: Biochemical Enzymatic Assay (IC50) Against WT and C481S BTK 
     A Caliper-based kinase assay (Caliper Life Sciences, Hopkinton, Mass.) was used to measure inhibition of WT and C481S Btk kinase activity of a compound of the present disclosure. Ibrutinib and ACP=196 was used as control compounds. Serial dilutions of test compounds were incubated with human recombinant WT BTK or C481S Btk (0.5 nM), ATP (16 μM) and a phosphoacceptor peptide substrate FAM-GEEPLYWSFPAKKK-NH2 (1 μM) at room temperature for 3 h. The reaction was then terminated with EDTA, final concentration 20 mM and the phosphorylated reaction product was quantified on a Caliper Desktop Profiler (Caliper LabChip 3000). Percent inhibition was calculated for each compound dilution and the concentration that produced 50% inhibition was calculated. 
     The following table shows the IC50 of WT BTK, C481S BTK, and the IC50 ratio of C481S vs WT BTK for Ibrunitib, ACP-196, certain compounds of the disclosure. As expected, both Ibrutinib and ACP-196 dramatically lost binding affinity to the C481S BTK enzyme: Ibrutinib is X990 fold weaker in C481S BTK than that of WT BTK, and ACP-196 is X483 fold weaker in C481S BTK than that of WT BTK. On the contrary, the inventor unexpectedly find that our compounds still potently inhibits the C481S BTK as compared to that of WT BTK. Example 2 is X64 more potent than Ibrutinib and X477 more potent than the ACT-196 in C481S BTK assay. These data suggest that our compounds such as Example 2 reversiblly binds to BTK by a different mechanism from the conventional covalent BTK inhibitors such as Ibrutinib and ACP-196, and so might be an important option for those patients that become resistant to Ibrutinib and ACP-196 due to a mutation in the C481 binding site.

     Biological Example 4: Calcium Flux Fluoresence-Based Assay 
     Calcium flux fluoresence-based assays were performed in a FlexStation 11384 fluorometric imaging plate reader (Molecular Devices) according to manufacturer instructions. In brief, actively growing Ramos cells (ATCC) in RPMI medium supplemented with 10% FBS (Invitrogen) were washed and re-plated in low serum medium at approximately 5×10 5  cells per 100 μl per well in a 96-well plate. Compounds to be assayed were dissolved in DMSO and then diluted in low serum medium to final concentrations ranging from 0 to 10 μM (at a dilution factor of 0.3). The diluted compounds were then added to each well (final DMSO concentration was 0.01%) and incubated at 37 degree in 5% CO 2  incubator for one hour. Afterwards, 100 μl of a calcium-sensitive dye (from the Calcium 3 assay kit, Molecular Devices) was added to each well and incubated for an additional hour. The compound-treated cells were stimulated with a goat anti-human IgM antibody (80 ug/ml; Jackson ImmunoResearch) and read in the FlexStation 11384 using a λ Ex =485 nm and λ Em =538 nm for 200 seconds. The relative fluorescence unit (RFU) and the IC 50  were recorded and analyzed using a built-in SoftMax program (Molecular devices). 
     Biological Example 5: Inhibition of B-Cell Activation—B Cell FLIPR Assay in Ramos Cells 
     Inhibition of B-cell activation by compounds of the present invention is demonstrated by determining the effect of the test compounds on anti-IgM stimulated B cell responses. The B cell FLIPR assay is a cell based functional method of determining the effect of potential inhibitors of the intracellular calcium increase from stimulation by an anti-IgM antibody. Ramos cells (human Burkitt&#39;s lymphoma cell line. ATCC-No. CRL-1596) were cultivated in Growth Media (described below). One day prior to assay, Ramos cells were resuspended in fresh growth media (same as above) and set at a concentration of 0.5×10 6 /mL in tissue culture flasks. On day of assay, cells are counted and set at a concentration of 1×10 6 /mLl in growth media supplemented with IμM FLUO-3AM (TefLabs Cat-No. 0116, prepared in anhydrous DMSO and 10% Pluronic acid) in a tissue culture flask, and incubated at 37° C. (5% CO 2 ) for one h. To remove extracellular dye, cells were collected by centrifugation (5 min, 1000 rpm), resuspended in FLIPR buffer (described below) at 1×10 6  cells/mL and then dispensed into 96-well poly-D-lysine coated black/clear plates (BD Cat-No. 356692) at 1×10 5  cells per well. Test compounds were added at various concentrations ranging from 100 μM to 0.03 μM (7 concentrations, details below), and allowed to incubate with cells for 30 min at RT. Ramos cell Ca 2+  signaling was stimulated by the addition of 10 μg/mL anti-IgM (Southern Biotech, Cat-No. 2020-01) and measured on a FLIPR (Molecular Devices, captures images of 96 well plates using a CCD camera with an argon laser at 480 nM excitation).
         Growth Medium: RPMI 1640 medium with L-glutamine (Invitrogen, Cat-No. 61870-010), 10% Fetal Bovine Serum (FBS, Summit Biotechnology Cat-No. FP-100-05); ImM Sodium Pyruvate (Invitrogen Cat. No. 11360-070).   FLIPR buffer: HBSS (Invitrogen, Cat-No. 141175-079), 2 mM CaCl 2 ) (Sigma Cat-No. C-4901), HEPES (Invitrogen, Cat-No. 15630-080), 2.5 mM Probenecid (Sigma, Cat-No. P-8761), 0.1% BSA (Sigma, Cat-No. A-7906), 11 mM Glucose (Sigma, Cat-No. G-7528);   Assay and Analysis: Intracellular increases in calcium were reported using a max-min statistic (subtracting the resting baseline from the peak caused by addition of the stimulatory antibody using a Molecular Devices FLIPR control and statistic exporting software. The IC 50  was determined using a nonlinear curve fit (GraphPad Prism).       

     Biological Example 6: In Vitro Anti-Proliferation Assay 
     Cell antiproliferation is assayed by PerkinElmer ATPlite™ Luminescence Assay System. Briefly, the various test cancer cell lines are plated at a density of about 1×10 4  cells per well in Costar 96-well plates, and are incubated with different concentrations of compounds for about 72 hours in medium supplemented with 5% FBS. One lyophilized substrate solution vial is then reconstituted by adding 5 mL of substrate buffer solution, and is agitated gently until the solution is homogeneous. About 50 μL of mammalian cell lysis solution is added to 100 μL of cell suspension per well of a microplate, and the plate is shaken for about five minutes in an orbital shaker at −700 rpm. This procedure is used to lyse the cells and to stabilize the ATP. Next, 50 μL substrate solution is added to the wells and microplate is shaken for five minutes in an orbital shaker at −700 rpm. Finally, the luminescence is measured by a PerkinElmer TopCount® Microplate Scintillation Counter. Such assays, carried out with a range of doses of test compounds, allow the determination of the cellular anti-antiproliferative IC 50  of the compounds of the present invention. 
     Biological Example 7: In Vivo Xenograft Studies 
     Typically, athymic nude mice (CD-1 nu/nu) or SCID mice are obtained at age 6-8 weeks from vendors and acclimated for a minimum 7-day period. The cancer cells are then implanted into the nude mice. Depending on the specific tumor type, tumors are typically detectable about two weeks following implantation. When tumor sizes reach ˜100-200 mm 3 , the animals with appreciable tumor size and shape are randomly assigned into groups of 8 mice each, including one vehicle control group and treatment groups. Dosing varies depending on the purpose and length of each study, which typically proceeds for about 3-4 weeks. Tumor sizes and body weight are typically measured three times per week. In addition to the determination of tumor size changes, the last tumor measurement is used to generate the tumor size change ratio (T/C value), a standard metric developed by the National Cancer Institute for xenograft tumor evaluation. In most cases, % T/C values are calculated using the following formula: % T/C=100×ΔT/ΔC if ΔT&gt;0. When tumor regression occurred (ΔT&lt;0), however, the following formula is used: % T/T0=100×ΔT/T0. Values of &lt;42% are considered significant. 
     Biological Example 8: Mouse Collagen-Induced Arthritis (mCIA) 
     On day 0 mice are injected at the base of the tail or several spots on the back with an emulsion of Type II Collagen (i.d.) in Complete Freund&#39;s adjuvant (CFA). Following collagen immunization, animals will develop arthritis at around 21 to 35 days. The onset of arthritis is synchronized (boosted) by systemic administration of collagen in Incomplete Freund&#39;s adjuvant (IFA; i.d.) at day 21. Animals are examined daily after day 20 for any onset of mild arthritis (score of 1 or 2; see score description below) which is the signal to boost. Following boost, mice are scored and dosed with candidate therapeutic agents for the prescribed time (typically 2-3 weeks) and dosing frequency, daily (QD) or twice-daily (BID). The developing inflammation of the paws and limb joints is quantified using a scoring system that involves the assessment of the 4 paws following the criteria described below: 
     Scoring: 
     1=swelling and/or redness of paw or one digit.
 
2=swelling in two or more joints.
 
3=gross swelling of the paw with more than two joints involved.
 
4=severe arthritis of the entire paw and digits.
 
     Evaluations are made on day 0 for baseline measurement and starting again at the first signs or swelling for up to three times per week until the end of the experiment. The arthritic index for each mouse is obtained by adding the four scores of the individual paws, giving a maximum score of 16 per animal. 
     Biological Example 9: Rat Collagen-Induced Arthritis (rCIA) 
     On day 0, rats are injected with an emulsion of Bovine Type II Collagen in Incomplete Freund&#39;s adjuvant (IFA) is injected intradermally (i.d.) on several locations on the back. A booster injection of collagen emulsion is given around day 7, (i.d.) at the base of the tail or alternative sites on the back. Arthritis is generally observed 12-14 days after the initial collagen injection. Animals may be evaluated for the development of arthritis as described below (Evaluation of arthritis) from day 14 onwards. Animals are dosed with candidate therapeutic agents in a preventive fashion starting at the time of secondary challenge and for the prescribed time (typically 2-3 weeks) and dosing frequency, daily (QD) or twice-daily (BID). The developing inflammation of the paws and limb joints is quantified using a scoring system that involves the assessment of the 4 paws following the criteria as described above. Evaluation are made on day 0 for baseline measurement and starting again at the first signs or swelling for up to three times per week until the end of the experiment. The arthritic index for each mouse is obtained by adding the four scores of the individual paws, giving a maximum score of 16 per animal. 
     Biological Example 10: Rat In Vivo Asthma Model 
     Male Brown-Norway rats are sensitized i.p. with 100 μg of OA (ovalbumin) in 0.2 ml alum once every week for three weeks (day 0, 7, and 14). On day 21 (one week following last sensitization), the rats are dosed q.d. with either vehicle or compound formulation subcutaneously 0.5 hour before OA aerosol challenge (1% OA for 45 minutes) and terminated 4 or 24 hours after challenge. At time of sacrifice, serum and plasma are collected from all animals for serology and PK, respectively. A tracheal cannula is inserted and the lungs are lavaged 3× with PBS. The BAL fluid is analyzed for total leukocyte number and differential leukocyte counts. Total leukocyte number in an aliquot of the cells (20-100 μî) is determined by Coulter Counter. For differential leukocyte counts, 50-200 μî of the sample is centrifuged in a Cytospin and the slide stained with Diff-Quik. The proportions of monocytes, eosinophils, neutrophils and lymphocytes are counted under light microscopy using standard morphological criteria and expressed as a percentage. Representative inhibitors of Btk show decreased total leucocyte count in the BAL of OA sensitized and challenged rats as compared to control levels.
