     BACKGROUND 
       [0002]    Kinases are a class of enzymes that function in the catalysis of phosphoryl transfer. Protein kinases participate in the signaling events, which control the activation, growth and differentiation of cells in response to extracellular mediators and to changes in the environment. In general, kinases fall into several groups; those that preferentially phosphorylate serine and/or threonine residues are generally referred to as serine/threonine kinases and those that preferentially phosphorylate tyrosine residues are generally referred to as tyrosine kinases [S. K Hanks and T. Hunter, FASEB J., 1995, 9, 576-596]. The tyrosine kinases include membrane-spanning growth factor receptors such as EGFR (S. Iwashita and M. Kobayashi, Cellular Signaling, 1992, 4, 123-132), and cytosolic non-receptor kinases such as Lck, ZAP-70 and Syk kinases (C. Chan et. Al., Ann. Rev. Immun., 1994, 12, 555-592). 
         [0003]    Inappropriately high protein kinase activity has been implicated in many diseases resulting from abnormal cellular function. This might arise either directly or indirectly, for example by failure of the proper control mechanisms for the kinase, related for example to mutation, over-expression or inappropriate activation of the enzyme; or by the over- or underproduction of cytokines or growth factors also participating in the transduction of signals upstream or downstream of the kinase. In all of these instances, selective inhibition of the kinase could have a beneficial effect. 
         [0004]    T cells plays a key role in transplant rejection, autoimmune diseases and the initiation of inflammatory responses and are thus a primary target for pharmaceutical intervention in these indications. The activation of T cells is a complex process that results in cell growth and differentiation. The engagement of the T cell receptor on mature peripheral T cells initiates multiple intracellular signals that lead to cellular proliferation and the acquisition of complex functions. The biochemical mechanisms that couple receptor binding to these intracellular events have been investigated (J. E. M., Van Leeuwen, and L. E. Samelson, Current Opin. Immun. 1999, 11, 242-248). The Syk family of tyrosine kinases, comprising Syk and ZAP-70, play a role in the initiation and the amplification of receptor signal transduction (D. H. Chu et. al., Immunol. Rev. 1998, 165, 167-180). ZAP-70 is expressed solely in T cells and NK cells. Syk is found in B cells, mast cells, neutrophils, macrophages, and platelets and is involved in B cell receptor and Fc receptor signal transduction. Thus, kinase inhibitors of ZAP-70 and Syk have potential therapeutic benefits for treating diseases resulting from activation and differentiation of T cells, NK cells, B cells, mast cells, neutrophils, macrophages, and platelets. 
       SUMMARY 
       [0005]    The invention relates to novel compounds and compositions including those compounds, as well as methods of using and making the compounds. The compounds are heterocyclic compounds that are useful in therapeutic applications, including modulation of disease or disease symptoms in a subject (e.g., mammal, human, dog, cat, horse). The compounds (including stereoisomers thereof) are created either singly or in a combinatorial fashion to give structurally, and stereochemically diverse libraries of compounds. The compounds are useful as ZAP-70 and Syk inhibitors through their binding to these receptors.

This invention also envisions the quaternization of any basic nitrogen-containing groups of the compounds disclosed herein. Water or oil-soluble or dispersible products may be obtained by such quaternization. 
         [0233]    The compounds of the formulae described herein can, for example, be administered by injection, intravenously, intraarterially, subdermally, intraperitoneally, intramuscularly, or subcutaneously, or orally, buccally, nasally, transmucosally, topically, in an ophthalmic preparation, or by inhalation, with a dosage ranging from about 0.001 to about 100 mg/kg of body weight, preferably dosages between 10 mg and 1000 mg/dose, every 4 to 120 hours, or according to the requirements of the particular drug. The methods herein contemplate administration of an effective amount of compound or compound composition to achieve the desired or stated effect. Typically, the pharmaceutical compositions of this invention will be administered from about 1 to about 6 times per day or alternatively, as a continuous infusion. Such administration can be used as a chronic or acute therapy. The amount of active ingredient that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. A typical preparation will contain from about 5% to about 95% active compound (w/w). Alternatively, such preparations contain from about 20% to about 80% active compound. 
         [0234]    Lower or higher doses than those recited above may be required. Specific dosage and treatment regimens for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health status, sex, diet, time of administration, rate of excretion, drug combination, the severity and course of the disease, condition or symptoms, the patient&#39;s disposition to the disease, condition or symptoms, and the judgment of the treating physician. 
         [0235]    Upon improvement of a patient&#39;s condition, a maintenance dose of a compound, composition or combination of this invention may be administered, if necessary. Subsequently, the dosage or frequency of administration, or both, may be reduced, as a function of the symptoms, to a level at which the improved condition is retained. Patients may, however, require intermittent treatment on a long-term basis upon any recurrence of disease symptoms. 
         [0236]    Pharmaceutical compositions of this invention comprise a compound of the formulae described herein or a pharmaceutically acceptable salt thereof, an additional agent including for example, a steroid or an analgesic; and any pharmaceutically acceptable carrier, adjuvant or vehicle.

         [0237]    The term “pharmaceutically acceptable carrier or adjuvant” refers to a carrier or adjuvant that may be administered to a patient, together with a compound of this invention, and which does not destroy the pharmacological activity thereof and is nontoxic when administered in doses sufficient to deliver a therapeutic amount of the compound. 
         [0238]    The pharmaceutical compositions may be in the form of a sterile injectable preparation, for example, as a sterile injectable aqueous or oleaginous suspension. This suspension may be formulated according to techniques known in the art using suitable dispersing or wetting agents (such as, for example, Tween 80) and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are mannitol, water, Ringer&#39;s solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose, any bland fixed oil may be employed including synthetic mono- or diglycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions may also contain a long-chain alcohol diluent or dispersant, or carboxymethyl cellulose or similar dispersing agents which are commonly used in the formulation of pharmaceutically acceptable dosage forms such as emulsions and or suspensions. Other commonly used surfactants such as Tweens or Spans and/or other similar emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or other dosage forms may also be used for the purposes of formulation.

     DELFIA Assay 
       [0266]    Before initiation of kinase reactions, compounds were pre-incubated with ZAP-70. Pre-incubation reactions contained 62.5 mM Mops pH 7.0, 12.5 mM MgCl 2 , 12.5% glycerol, 3.1 nM ZAP-70, 62.5 nM biotinylated poly(glu,Tyr), 0.1 mg/ml BSA, 6.25% DMSO and 0-100 mM compound in a total volume of 40 ml. After a 10 minute room temperature incubation, 10 ml of 5 mM ATP was added to start the reaction. Reactions were incubated at room temperature for 30 minutes then terminated by addition of 5 ml 500 mM EDTA. The amount of phosphate transferred to biotinylated poly(glu,tyr) was measured using the Dissociation Enhanced Lanthanide Fluorescence Immuno-assay (DELFIA) from Perkin Elmer according to manufacturers protocol. Briefly, biotinylated poly (gly,tyr) was captured on streptavidin coated plates, washed twice, then incubated with Europium labeled-anti-phosphotyrosine antibody. Free antibody was removed with six washes, Europium was dissociated from the antibody, and Europium fluorescence was measured at using an excitation wavelength of 340 nM and an emission wavelength of 615 nM.

       Example 6 
     Cell-Based Assay of ZAP-70-Mediated LAT Phosphorylation 
       [0267]    ZAP-70 tyrosine kinase activity present in activated Jurkat T cells was measured by assessing the phosphorylation status of LAT. LAT is a palmitoylated p36/38 kDa plasma membrane-associated protein expressed in all T lymphocytes and it is the physiologic substrate of activated ZAP-70. When Jurkat cells are stimulated with an anti-CD3 monoclonal antibody, which crosslinks the surface antigen receptor-CD3 complex, ZAP-70 becomes activated and phosphorylates two tyrosine residues on LAT, Tyr-191 &amp; Tyr-226. Therefore, assessment of LAT Tyr-191 and Tyr-226 phosphorylation in anti-CD3 stimulated Jurkat T cells is a specific measure of intracellular ZAP-70 activity. Accordingly, compounds that inhibit Tyr-191 and Tyr-226 phosphorylation of LAT indicate successful antagonism of ZAP-70 tyrosine kinase activity or upstream activation of the ZAP-70 pathway. 
         [0268]    Jurkat cells (ATCC) cultured at 15-20×106 cells/mL are pre-incubated for 15 mins at 370° C. with inhibitor compounds, or carrier (DMSO), and then are stimulated for 5 min. by the addition of 1 mg/mL final concentration of anti-CD3 monoclonal antibody (UCHT-1 or OKT-3; E-Bioscience). The cells are then lysed by a detergent-based buffer and extracts are used for immunoprecipitation of all phosphotyrosine-containing proteins using a commercially available phosphotyrosine specific monoclonal antibody (4G10; Upstate Biotechnology Inc.) and protein-A-conjugated agarose beads. After washing the immune complexes to remove non-specifically bound proteins, the immunoprecipitated phosphotyrosine proteins are liberated from the agarose beads by boiling and denaturing and are resolved by SDS-PAGE and transferred to nitrocellulose membranes. LAT phosphorylated on Tyr-191 and Tyr-226 is then detected by standard western blotting technology using commercially available phospho-specific antibodies that react specifically with either phospho-Tyr-191 or phospho-Tyr-226 on LAT (Upstate Biotechnology Inc.), an enzyme-conjugated secondary antibody (horseradish peroxidase-conjugated goat anti-rabbit IgG antiserum), and a Storm Imaging system (Amersham-Pharmacia). 
         [0269]    Inhibition was observed with representative compounds described herein. 
       Example 7 
     IL-2 Inhibition Cell-Based Assay 
       [0270]    IL-2 production was measured in Jurkat cells following co-stimulation with Anti-CD3 and Anti-CD28 antibodies. Cells were seeded at 1×10 5 /well (200 μl/well of culture) in 96 well plates precoated with anti-CD3 antibody (BD Biocoat T-cell activation plates, Anti-human CD3 plate=Cat. No. 354725 from BD BioSciences). Anti-CD28 antibody (eBioScience, Cat# 16-0289-85; Functional Grade, co-stimulatory, clone 28.2) is added to the plate at the final concentration of 20 ng/well. Cells are incubated for 48 hrs after which a 50 μl aliquot of cell supernatant is removed for IL-2 titration. IL-2 titration was performed using the Endogen enzyme-linked immunosorbent assay (ELISA) Kit (Endogen of Pierce, Cat# EH2-IL2-5) as described by the manufacturer. In brief, this assay consists of using a 96 well microtiter plate that has been precoated with anti-IL-2 antibodies for the capture of human IL-2. In order to detect the captured IL-2, a biotinylated second anti-IL-2 antibody is added to all wells. This results in a sandwiching of any IL-2 (capture IL-2 Ab C IL-2 C detection IL-2-biotin Ab). Following the removal of unbound antibodies, by a series of washings, a horseradish peroxidase (HRP) conjugate with a high affinity for biotin is added. Unbound Strepavidin-HRP is removed and the bound enzyme labeled antibodies can then be measured via a chromogenic reaction with the addition of TMB substrate. The resulting chromogenic reaction is stopped using H 2 SO 4  (Stop Solution) and the optical density of each well is then read at the appropriate wavelength. The level of substrate conversion is colormeterically determined by measuring the absorbance that is proportional to the amount of IL-2.
