Description: Title: PURINE INHIBITORS OF CYCLIN DEPENDENT KINASE 2 and IκB-α BACKGROUND OF THE INVENTION This is a continuation-in-part of U.S. Patent Application S.N. 09/230,829, filed on January 29, 1999, which claims priority to PCT Application No. PCT/US97/13386, filed on August 1, 1997 which in turn is a continuation-in-part of co-pending U.S. Patent Application Serial No. 08/692,012 filed August 2, 1996. (1) Field of the Invention This invention concerns 2,6,9-trisubstituted purines that have been discovered to be selective inhibitors of cell cycle kinases and, as such, the compounds are inhibitors of cell proliferation. The 2,6,9-trisubstituted purines are useful in for example in - treating autoimmune diseases, e.g. rheumatoid arthritis, lupus, type I diabetes, multiple sclerosis, etc., in treating cancer, cardiovascular disease, such as restenosis, host vs graft disease, gout, polycystic kidney disease and other proliferative diseases whose pathogenesis involves abnormal cell proliferation. This invention also concerns 2,6,9-trisubstituted purines that have been discovered to be potent and specific inhibitors of IκB-α kinase which prevents signal induced NF-κB activation and cytokine synthesis in vitro and in vivo. Such inhibitors are expected to inhibit the synthesis of cytokines and adhesion proteins whose synthesis is transcriptionally regulated by NF-κB. Proinflammatory cytokines such as 1L-1, 1L-6, TNF and adhesion proteins (e.g. ICAM, VCAM and selections) belong to this class of molecules and have been implicated in the pathogenesis of inflammatory diseases. Thus a potent inhibitor of IκB-α kinase is useful in the clinical management of diseases where NF-κB activation is required for disease induction. (2) Description of the Art In the past few years, advances in molecular and cellular biology have contributed to our understanding of the mechanisms of cell proliferation and of specific events that occur during progression of cells through mitosis. E.g., "Progress in Cell Cycle Research" Vol 1, Eds. L. Meijer, S. Guidet and H.Y.L. Tung; Plenum Press, New York, 1995. These studies have shown that progression through the cell cycle is controlled by a family of serine/threonine kinases called cyclin dependent kinases. These enzymes contain (a) a catalytic protein called cyclin dependent kinase (CDK) that uses ATP as a substrate and (b) a regulatory protein called cyclin. Different cyclin-CDK combinations control events such as growth, DNA replication and cell division. One key member of the CDK family of enzymes is CDK2. CDK2 activity has been shown to be essential for mammalian cell cycle progression at the Gl/S boundary. Microinjection of antibodies directed against CDK2 blocks the progression of human diploid fibroblasts into the S phase of the cell cycle. Expression of a CDK2 dominant negative mutant in human osteosarcoma cells has a similar effect. Together, these studies indicate that inhibition of cellular CDK2 activity will prevent progression of cells through the mitotic cycle and induce growth arrest prior to the S phase. Consistent with this view, in vitro studies with olomoucine (2-(hydroxyethylamino)-6- benzylamino-9-methylpurine), have shown that it is a specific inhibitor of CDK2 with an IC 50 of approximately 2.1 μg/ml J. Vesely, et al.; Eur. J.Biochem 224, 771-786 (1994), L. Meijer "Chemical Inhibitors of Cyclin-Dependent Kinases" pp 351-356 in "Progress in Cell Cycle Research Vol 1, Eds. L. Meijer, S. Guidet and H.Y.L. Tung; Plenum Press, New York, 1995. In vivo studies using mammalian cells in culture have shown that olomoucine inhibits cell proliferation at an approximate concentration of 50 μg/ml. In this invention, we have developed several compounds whose biological activity is considerably more potent than olomoucine. In vivo studies using mammalian cells indicate that some of the disclosed compounds inhibit cell proliferation at concentrations that are significantly lower than olomoucine. Recently an IκB-α kinase activity has been described in the cytoplasm of stimulated human umbilical vein endothelial cells (Bennett et al (1996) J. Biol.Chem 271, 19680- 19688). Some of the compounds of this invention have been identified as potent and specific inhibitors of IκB-α kinase which prevents signal induced NF-κB activation and cytokine synthesis in vitro and in vivo. The activation of the heterodimeric transcription factor NF-κB is a complex process. In unstirnulated cells, the NF-κB (p50/p65) heterodimer is located in the cytosol where it is complexed with an inhibitory subunit IκB- α, IκB-α, binds to NF-κB thus masking its nuclear localization signal and preventing translocation to the nucleus. Upon stimulation of cells with a variety of signals (e.g. lipopolysaccharide) IκB- is rapidly phosphorylated, uniquitinated and degraded by the proteasome. Degradation of IκB-α, allows the translocation of NF-κB to the nucleus where it activates transcription of a number of inflammatory response genes. These observations suggest that IκB-α kinase is an attractive target for the identification of inhibitors that may be useful in the treatment of inflammatory diseases where NF-κB activation is required for disease induction.

Table 5 identified compounds of this invention that were prepared according to the synthesis method set forth in this Example. Table 6 Compounds Prepared By The Method of Example 6 EXAMPLE 7 Composition of this invention were evaluated in the following assays. CDK2 assays: Compositions of this invention were assayed to determine their CDK2 inhibitory activity. The assay system (total volume of 50 μl) contained 50 mM Tris-Cl, pH 7.4, 10 mM MgCl 2 , 5 mM DTT, 1 μg of histone HI, 30 μM ATP (1 μCi of gamma 32 P labeled ATP), lO μg ofBSA and 1 ng of purified CDK2. After incubation at 30°C for 30 min, the reaction was terminated by the addition of 10 μl of 10% TCA and the samples were blotted onto to nitrocellulose filters. These filters were washed extensively in 10% TCA and assayed for radioactivity. Blanks contained no enzyme. To ascertain the potency of various compounds of this invention, the compounds were added to the above assay at concentrations ranging from 100 to 0.02 μg/ml. After incubation at 30 min., the assay tubes were processed as above. In all assays, various concentrations of olomoucine were added and were used as a standard positive control. The IC 50 (enzyme) listed in Table 7 is defined as the concentration required to inhibit CDK2 activity by 50%. EXAMPLE 8 Cell Proliferation Assays; Early passage rat aortic smooth muscle cells (CV Therapeutics Cell repository) were seeded in 48 well dishes (Falcon, ml/well) at a density of 20,000 cells/ml of DME containing 5% heat inactivated bovine serum. The cells were incubated in a standard tissue culture incubator for 48 hr. The medium was aspirated and the wells were replenished with 0.2 ml of fresh medium. Compounds of this invention were added at concentrations ranging from 100 to 0.37 μg/ml. After 48 hr incubation, the medium was aspirated and the cultures were treated with 0.2 ml of saline 0.25 μl of phenozine methosulfate solution containing MTS (Cell Titer 96 ® Aqueous Non-radioactive cell proliferation assay kit, Catalog # G 5430, Promega, 2800 Woods Hollow Road, Madison, WI 53711-5399). The IC 50 cells listed in Table 6 is defined as the concentration required to inhibit cell proliferation by 50%. Olomoucine at various concentrations was added and was used as a standard positive control. The inhibition of cell proliferation properties of the compounds of this invention are demonstrated by their ability to inhibit cell proliferation in the range of about 0.05 μg/ml to 100 μg/ml, preferably less than 0.5 μg/ml. Similar assays were performed using the following cell lines; P388 - mouse lymphoid neoplasm; L1210 - mouse lymphcytic leukemia; Caco2 human colon adenocarcinoma; MCF7 human breast adenocarcinoma; PupVSMC rat neonatal aortic smooth muscle cells; Ovcar human ovarian Carcinoma; Panel human pancreatic adenocarcinoma; and HUVEC human umbilical cord endothelial cells. The inhibitory activity of several compositions of this invention against one or more of the cell lines are reported in Tables 8 and 9 below. Table 9 MRC-5 = Human Fibroblast PupVSMC = Rat neonatal aortic smooth muscle cells EXAMPLE 8 Compounda of this invention was evaluated for effectiveness using the Murine Leukemia Model. The Murine Leukemia Model is a standard model used in the evaluation of antitumor agents. CDF1 mice were injected ip with L1210 cells (lxlO 3 cells/mouse). Twenty-four hours later, these mice were treated with various doses (ip) of compound 3 of Example 1 in saline. The dosing regimen used in this study is outlined in Table 10, below. Mice were dosed with compound 3 daily or on alternate days. Control mice received saline. After 7 days, dosing was suspended and survival monitored. Table 10 The results indicate that rats administered compound 3 survived longer than the control rats. EXAMPLE 9 This example measured the effect of an acute local delivery of compound 3 of Example 1 in reducing neointima formation following balloon angioplasty in the rat carotid artery model. In this example, the left common carotid arteries of adult male rats (n=10 per experimental group) were surgically injured using a Fogarty arterial embolectomy catheter. Immediately after injury, the common carotid artery was bisected with a vascular clamp, thereby establishing an untreated and treated segment. A drug delivery catheter was then inserted into the distal half of the common carotid. After drug delivery, the catheter was removed and excess drug was washed out by removing the vascular clamp and re-establishing blood flow before closing the artery. The animals were allowed to recover for 14 days before harvesting the common carotid artery. The harvested tissue was sectioned and the neointimal area was digitized and measured with a computer planimetery system. For each animal, 15 measurements were averaged for the untreated segment and 15 for the treated. {2-[(2- aminoethyl)amino]-9-( methylethyl)purin-6-yl} [(4-chlorophenyl)methyl]amine was administered at a dose of 5 mg/mL reducing the neointimal area about 90% in comparison to the 6% reduction of saline alone. The results of this Example are found in Figure 1. According to Figure 1, administering compound 3 of Example 1 to a damaged carotid artery reduced the neointimal area about 88% in comparison to the 6% reduction produced by the saline vehicle alone. EXAMPLE 10 IκB-α Kinase Assays: Compositions of this invention were assayed to determine their IκB-α kinase inhibitory activity. The human umbilical vein endothelial cell line (HUVEC) used in these studies was purchased from Clonetics (San Diego, CA) and was maintained in endothelial cell growth medium supplemented with 2% fetal bovine serum, lOng/ml human recombinant epidermal growth factor, 1 μg/ml hydrocortisone, 50 μg/ml gentamicin, 50 ng/ml amphotericin B and 12 μg/ml bovine brain extract at 37°C in a tissue culture incubator. All growth media and supplements were purchased from Clonetics (San Diego, CA). E. coli lipopolysaccharide (LPS) serotype 0111 :B4 was purchased from Sigma (Saint Louis, Ml). All other chemicals were of reagent grade. Preparation of cell Lysate: Monolayers (75 cm 2 ) of HUVEC cells were treated with LPS (100 ng/ml) for 5 minutes after which the cell media was rapidly removed and the monolayer washed three times with ice cold PBS. The cell layer was scraped into 10 ml PBS and the cells pelleted by centrifugation (3000 rpm, 5 min, 4°C). Cell lysate was prepared by incubating the cell pellet in 0.2 ml lysis buffer (20mM HEPES, pH7.3, 50mM NaCl, lOmM MgCl 2 , lmM EDTA, lmM EGTA, lmM sodium orthovanadate, lOmM β-glycerophospate, lmM phenylmethylsulfonylfuoride, lmM dithiothreitol, 0.5% Nonidet P-40 for 15 minutes at 37°C for frequent vortexing. Cell debris was removed from the sample by microcentrifugation (10,000xg, 15 minutes, 4°C) and the supernatant was "precleared" by the addition of 100 ml of a suspension of sepharose 4B in lysis buffer and mixing gently for 1 hour at 4°C. The speharose 4B beads were removed by microcentrifugation and the supernatant aliquotted and stored at 80°C. Solid Phase IκB-α kinase assay: 1 μg of GST- IκB-α, corresponding to full length IκB-α of human origin, (Santa Cruz Biotechnology,) was incubated with 20 μl of a 50% slurry of glutathione S sepharose 4B (Pharmacia) in reaction buffer (20mM HEPES, pH7.3, lOmM MgCl 2 , 15mM β-glycerophosphate, 0.5mM sodium orthovanadate, 0.5mM EGTA) for 30 minutes at room temperature. The GST- IκB-bead complex was the washed three times with 0.5 ml of reaction buffer by resuspension and microcentrifugation. lOμg of HUVEC cell lysate protein in lOOμl of reaction buffer was then added to the GST- IκB-bead complex and the mixture incubated with gentle mixing at 4°C for 1 hour. The bead complex was then washed three times with reaction buffer containing 0.2 M NaCl and once with reaction buffer alone. Finally the bead complex was resuspended in 20μl of reaction buffer containing 5μCi [y- 32 P]ATP (>5000 ci/mmol, New England Nuclear Corp. Boston, MA) and incubated at room temperature for 15 minutes. The reaction was terminated by the addition of lOμl of SDS- PAGE sample buffer and boiled for 3 minutes before separation by SDS-PAGE (10-20% gradient Readygel, BioRad). Following electrophoresis the gel was fixed (50% methanol 10%) acetic acid) for 15 minutes, washed three times for 5 minutes each with distilled H 2 0 and treated with 5% glycerol for 15 minutes before drying down and exposing to film for autoradiography (X-OMAT XAR-5 Kodak). In gel kinase assay: IκB-α isozymes were assayed for activity using a modification of previously published methods (11, 19, 20). Briefly duplicate samples of the IκB-glutathione sepharose 4B bead complex were prepared as described above and were separated by electrophoresis through a 12% SDS-PAGE gel which had been polymerised in the presence of 15 μg/ml GST- IκB- . Following electrophoresis the gel was washed gently twice for 30 minutes each with 50mM Tris-HCI pH8.0, 5mM β-mercaptoethanol; 20% isopropanol to remove SDS. Proteins were then denatured within the gel by incubation for 45 minutes in 100ml 50mM Tris-HCl pH8.0; 5mM β-mercaptoethanol; 0.04% Tween 40. The gel was then cut in half to separate the duplicate samples, one half was incubated in 10 ml reaction buffer alone and the other in 10 ml reaction buffer containing lOμg/ml of 2-diethanolamino-6(4- phenyl anilino)-9-isopropyl purine (compound 6 of Example 2) for 1 hour at room temperature which 10μCi[y- 32 P]ATP was added and the incubations continued for a further hour at room temperature. The gels were then subjected to multiple 15 minute washes of 100ml each 5% trichloroacetic acid containing 1% sodium pyrophosphate until 1 ml of wash solution gave close to background radioactivity. The gels were then dried down and exposed to file for autoradiograhy. Preparation of 2-diethanolamino-6-(4-phenvbenzylaminoV9-isopropyl purine Epoxy activated Sepharose 6B Affinity Matrix. Freeze dried epoxy activated Sepharose 6B (Pharmacia LKB, Piscataway, NJ) was chosen for the coupling reaction due to its ability to form an ether bond between an hydroxyl-containing ligand and the epoxide group on the sepharose. The gel was swollen according to the manufacturer's instructions, (lOOmg) of compound 6 of Example 2 was dissolved in 1ml coupling solution (1.2:1 v/v dimethylformamide : 0.1N NaOH) and mixed with 0.5ml of swollen gel at pH 10-11 for 72 hours at room temperature with gentle agitation. Excess reactive groups were blocked with 1M ethanolamine for 4 hours at 50°C and the gel slurry was poured into 1 ml syringe column. The resin was activated with three alternating cycles of twenty column volumes each of pH 4.0 (0.1M acetate, 0.5M NaCl) and pH 8.0 (0.1M Tris-HCl, 0.5M NaCl) buffers followed by twenty column volumes of reaction buffer (20mM HEPES, pH7.3, lOmM MgCl 2 , 15mM β-glycerophophate, 0.5mM sodium orthovanadate, 0.5mM EGTA). The column was stored at 4°C in reaction buffer containing 0.5%) sodium azide and regenerated prior to each use with alternating cycles of low and high pH as described above. Activated HUVEC cell lysate (500μg protein in 1ml reaction buffer) was passed over the CVT-1545 sepharose matrix sequentially five times and the flow through was saved (unbound material). The matrix was then washed three times with 1ml of reaction buffer (wash 1-3) then three times each with reaction buffer containing 0.5M NaCl (eluate 1-3). Aliquots (20μl from 1ml) of each sample were assayed for their ability to phosphorylate at GST- IκB-sepharose bead complex and analyzed by SDS-PAGE as described above. Assay of affinity enriched IκB-α kinase. The bulked 0.5 M NaCl eluates from the affinity matrix were used as the source of enzyme for development of an IκB-α kinase filter assay. Each reaction contained affinity enriched IκB-α kinase (lμg protein), lOng GST IκB-α kinase and 0.5μCi[y- 32 P]ATP (>5000 Ci/mmol, New England Nuclear Corp, Boston, MA) in 20μl reaction buffer. The reaction was incubated for 15 minutes at room temperature and was terminated by the addition of 2μl 0.5M EDTA. Reaction mixtures were blotted onto phosphocellulose disks (Gibco BRL Life Technologies, Gaithersburg, MD) and the filters washed three times with 0.15M phosphoric acid with gentle shaking for 15 minutes (up to ten filters were washed with 300 ml of 0.15M phosphoric acid.) Following a third wash the filters were air dried, added to scintillation fluid and assayed by liquid scintillation spectrometry. Electrophoretic Mobility Shift Assay: Nuclear extracts were prepared using a high-salt buffer extraction procedure. 10 pmol of double stranded NF-κB consenses oligonucleotide (5'- AGTTGAGGGGACTTTCCCAGGC-3') )Promega) was 5' end labeled with 5μCi [y- 32 P]ATP (>5000 Ci mmol, New England Nuclear Corp, Boston, MA) by incubaton with T4 polynucleotide kinase for 1 hr at 37°C. Unincorporated nucleotides were removed by pasing the reaction mixture over 1ml Sephadex G-5-spin column. Binding assays were performed at room temperature for 1 hr and consisted of lOμg nuclear extract protein, lμg salmon sperm DNA, and 5x10 4 cpm of 32 P labeled consensus of ohgonucleotide in the presence and absence of fifty fold unlabeled oligonucleotide. DNA-protein complexes were resolved by 8% non denaturing polyacrylamide gel electrophoresis, the gels were dried onto filter paper and visualized by autoradiography.
