Description: CD45 INHIBITORS Background Field of the Invention Compounds, compositions and methods for the treatment of immunologically-related diseases and disorders such as autoimmune disorders and organ graft rejection. Related Art Action of the immune system is known to be involved in immunologically-related diseases and disorders such as autoimmune disorders and in organ graft rejection ("OGR"). Hematopoietic, thymus-derived cells, (so-called "T cells") have an important and pervasive role as regulators and effectors of the functions of the immune system. Hematopoietic cells, and T cells in particular have on their surfaces a major transmembrane glycoprotein designated CD45, characterized by a cluster of antigenic determinants. CD45 is also known as leukocyte common antigen ("LCA"). The cytosolic portion of CD45 has protein tyrosine phosphatase ("PTP") activity and CD45 activity is known to be essential for TCR initiated T cell activation. Studies in CD45-deficient cell lines have shown that CD45 is a positive regulator of the T-Cell Receptor ("TCR") and that CD45 functions in TCR regulation by dephosphorylating the src kinases p56 ' and p59 . which allows autophosphorylation of the positive regulatory site on these enzymes: these reactions lead to downstream events and ultimately to T cell activation. Available treatments for autoimmune disorders and OGR have therapeutic disadvantages. For example. Cyclosporin A, the drug most commonly used to treat OGR, has renal and CNS toxicity. Summary of the Invention Potent inhibitors of CD45 have been discovered. Such inhibitors are useful for the treatment of various autoimmune disorders as well as for treatment of OGR. Inhibition of the phosphatase activity of CD45 by compounds of the present invention has been shown by incubating the cytosolic portion of CD45 with the compounds and / nitrophenyl phosphate (pNPP), a phosphatase substrate. Spectrophotometric monitoring has shown that the liberation of/j-nitrophenol from the substrate by CD45 is inhibited in the presence of the compounds disclosed herein.

Example 58: A compound in accord with structural diagram IX: IX A compound in accord with structural diagram IX having the N-Ac-amino acid sequence N-Ac-Glu-Gly-Gln was synthesized as follows: FMOCAsp(OH)OtBu (3.3 g, 8 mmol) and N-methylmorpholine (900 μL, 8 mmol) were dissolved in dry THF (20 mL) and chilled to -10 °C. Isobutylchloro formate (910 μL, 7 mmol) was added dropwise, maintaining reaction temperature below -7 °C. To this mixture was added a suspension of 2-amino- phenanthrene-9, 10-dione (1.12 g, 5 mmol) in dry THF (40 mL), and the reaction was allowed to warm to ambient temperature. The disappearance of 2-aminophenanthrene-9,10-dione was monitored by TLC (R f = 0.42, 25:75 EtOAc:CH 2 Cl 2 , v/v on a silica gel plate), and reaction was complete after 7 d. The solvent was removed by rotary evaporation and the residue was partitioned between EtOAc and sat'd. aq. ΝH 4 C1. The organic phase was washed with sat'd. aq. NaHCO 3 and brine, then dried over anhydrous MgSO 4 . This mixture was filtered and the filtrate was concentrated to a red-brown solid and chromatographed on silica gel with 15:85, EtOAC:CH 2 Cl 2 , v/v. This gave FMOCAsp-2-aminophenanfhrene-9,10-dione (1.92 g, 3.1 mmol. 63%) as a red solid. This intermediate was dissolved in CH 2 C1 (100 mL) and TFA (30 mL) was added; after lh the volatiles were removed by rotary evaporation. Residual TFA was removed by dissolving the material in CH 2 CI2 and concentration on the rotary evaporator twice. This was dissolved in dry CH2CI 2 (100 mL). diisopropylethylamine (5 mL) and dry DMF (10 mL) were added under N 2 . 2-chlorochlortrityl resin (4.5 g of 1.2 mmol/g, 5.5 mmol) was added to the mixture and mixed by shaking. After 3 h, MeOH (10 mL) was added and the shaking was continued for an additional 10 min. The resin was collected by vacuum filtration and washed with CH 2 C1 2 (5 x 10 mL), DMF (2 x 10 mL). CH 2 C1 2 (2 x 10 mL) and MeOH (3 x 10 mL). The resin was dried for 64 h in vacuo. An incorporation of 2.3 mmol of FMOCAsp(3-aminophenanthrene-9,10-dione) was calculated based on the increase of mass to 5.8 g. The resin was swelled in DMF (25 mL) for 1 h, then washed with DMF (5 x 25 mL). The resin was treated with 20% piperidine in DMF (10 mL) for 3 min, drained, then was treated with more 20% piperidine in DMF (10 mL) for 7 min and drained. The resin was washed with DMF (10 x 10 mL). A solution of FMOCGln(trt)OH (6.72 g, 1 1 mmol), HATU (3.8 g, 10 mmol), and diisopropylethylamine (3.5 mL) in DMF (15 mL) was added to the resin and mixed with gentle nitrogen bubbling for 2 h. The solution was drained and the resin was washed with DMF (10 x 10 mL). The resin was treated with 10 ml 20% piperidine in DMF (10 mL) for 3 min, drained, then another portion of 20% piperidine in DMF (10 mL) was added for 7 min and drained. The resin was washed with DMF (10 x 10 mL). A portion of the resin (ca. 10%) was removed for other reactions and the remaining resin was treated with a solution of FMOCGlyOII (1.93 g, 1 1 mmol), HATU (3.8 g, 10 mol), diisopropylethylamine (3.5 mL) in DMF (15 mL) for 1 h. The reaction was drained and washed with DMF ( 10 x 10 mL). The resin was treated with 20% piperidine in DMF (10 mL) for 3 min, drained, then treated with additional 20% piperidine in DMF (10 mL) for 7 min and drained. The resin was washed with DMF (10 x 10 L). A portion of the resin (about 10%) was removed for other reactions and the remaining resin was treated with a solution of FMOCGlu(tBu)OH (4.68 g, 1 1 mmol), HATU (3.8 g. 10 mmol). and diisopropylethylamine (3.5 mL) in DMF (15 mL) for 16 h. The solution was drained and the resin was washed with DMF (10 x 10 mL). The resin was treated with 20% piperidine in DMF ( 10 mL) for 3 min, drained, then additional 20% piperidine in DMF (10 mL) was added for 7 min and drained. The resin was washed with DMF (10 x 10 mL). A portion of this material (ca. 15%) was removed and treated with a solution of AC 2 O (1 mL) and diisopropylethylamine (2 mL) in DMF (5 mL) for 2 h. The solution was drained and washed withDMF (10 x 5 mL), CH2CI 2 (5 x 5 mL), Et 2 O (5 x 5 mL) and dried under a N 2 stream. The resin was treated with a solution of TFA containing 2% H 2 O and 2% thioanisole (5 mL) for 2 h. The solids were removed and the solution was concentrated to a red oil. Addition of Et 2 θ ( 10 mL) induced precipitation of a red solid. which was collected by vacuum filtration. The material was purified by preparative HPLC on a Ci 8 Dynamax column (21.4 mm X 25 cm, 60 A) using a gradient of 10% to 26% acetonitrile in H 2 O with 0.1% TFA. Fractions containing pure product were combined and lyophilized to give the product (40 mg) as a red solid. HPLC: 2.69 min; HRMS theor. [M+H]:695.2313 amu; obs.

Method B: Cytotoxicity Assay: Calcein-AM (Molecular Probes, Eugene, OR) uptake, as a quantitative measure of cell viability, was used to evaluate the toxic effect of compounds on T cells. Briefly, PBMC were treated for 3-7 days with 3-10 μg/ml PHA, a potent T-cell mitogen, to preferentially expand the T-cell population. (Bradley, Linda M. Cell Poliferation in Selected Methods in Cellular Immunology, Eds. Mishell, B.B. and Shiigi. S.M.. W.H. Freeman and Co., San Francisco, 1980.) The T-cell lymphoblasts were purified by separation over Lymphoprep, plated at 2 x 1 OVwell in a round bottom 96-well plate containing RPMI with compound and incubated overnight at 37 °C in an incubator containing 5% CO2. The dilution scheme and culture media were the same as those used in the T-cell proliferation assay.

Enzyme was incubated with substrate, with or without compound, at room temperature for 1.5 h. At the end of the incubation period, BIOMOL "Green Reagent" (BIOMOL, Plymouth Meeting. PA) was added to each well, the plates incubated at room temperature for 30 min and absorbance read at 620 nm. Method D: Cell isolation and T cell proliferation assay: Whole blood was obtained from healthy human blood donors. Peripheral blood mononuclear cells ("PBMC") were isolated using Lymphoprep density-gradient centrifugation (Nycomed Amersham, Oslo, Norway), washed, counted and resuspended at 2 X 10 6 cells/mL in RPMI 1640 medium containing glutamine, 0.1 mg/mL gentamycin and 10% heat inactivated human serum. PBMC were transferred to 96-well plates (2 X 10 "1 cells/well) containing compound or vehicle control, with the final concentration of DMSO not to exceed 0.3%, and incubated for 1 hour before addition of the activating anti-CD3 antibody, OKT3 (30 ng/mL). After 24 hours in culture, the cells were pulsed with [ 3 H]thymidine (1 μCi/well) overnight and harvested the next day onto 96-well Packard GF/C filter plates using a Packard Cell Harvester (Packard Instruments, Meriden, CT). The filter plate was dried, the bottom of the plate sealed. 25 μL of Microscint 20 scintillation fluid added to each well, the top of the plate sealed with TopSeal-A, and the plate counted on a Packard TopCount. The data from the TopCount is transferred into Excel 5 (Microsoft, Redmond, WA) and formatted for ECso determination using Prism software (GraphPad Software, San Diego, CA). Table 4 shows the inhibition of CD45 activity in the /JNPP asssay and the lck assay certain compounds of the present invention. Inhibition in the T cell proliferation assay, as well as results from T cell cytotoxicity assay are shown. Table 4:
