Characterization of the cell cycle has introduced CDKs and other proteins as possible targets for inhibition of cell proliferation, such as, CDK1 and CDK2, whose inhibition may be useful in the treatment of proliferative disorders. Structure-activity analyses have been instrumental in the design and discovery of potent CDK inhibitors, such as purine analogs, which have increased in potency from the micromolar to the nanomolar level. X-ray crystallography and molecular modeling have provided evidence that these compounds act on the CDK target enzyme. Selected CDK inhibitors have successfully entered clinical trials. Further characterization of the cell cycle to identify molecular targets to inhibit cell proliferation, QSAR and SAR studies, and clinical trials may expedite the development of CDK inhibitors for therapeutic use. The ultimate goal of these studies is to determine whether specific CDKs, CDK1 or CDK2, are enzymes essential to cell proliferation that can be targeted for treatment of proliferative disorders. CDK1 and CDK2 are viable molecular targets for cancer therapies based on isolated-enzyme inhibition by CDK inhibitors, successful clinical trials of CDK1 and CDK2 inhibitors, and x-ray crystallographic confirmation of CDK inhibitors binding to the putative target enzyme active site. It is now reported that CDK1 inhibitory activities of purine analogs correlate with the physiochemical parameters of purine analogs. Enzyme inhibition [1-5], clinical trials (see Tab. 1), x-ray crystallographic [4, 6, 7] and QSAR correlation studies are evidence that specific CDK1 and/or CDK2 inhibitors are potentially useful agents for various cell-proliferation disorders. A brief overview of the cell cycle precedes a literature review of clinical applications of CDK inhibitors, followed by a new QSAR study, and a SAR and molecular modeling discussion.
