STRUCTURE OF CDK2/CYCLIN A WITH PNU-292137

OverviewOverview

Abnormal proliferation mediated by disruption of the normal cell cycle, mechanisms is a hallmark of virtually all cancer cells. Compounds, targeting complexes between cyclin-dependent kinases (CDK) and cyclins, such as CDK2/cyclin A and CDK2/cyclin E, and inhibiting their kinase, activity are regarded as promising antitumor agents to complement the, existing therapies. From a high-throughput screening effort, we identified, a new class of CDK2/cyclin A/E inhibitors. The hit-to-lead expansion of, this class is described. X-ray crystallographic data of early compounds in, this series, as well as in vitro testing funneled for rapidly achieving in, vivo efficacy, led to a nanomolar inhibitor of CDK2/cyclin A, (N-(5-cyclopropyl-1H-pyrazol-3-yl)-2-(2-naphthyl)acetamide (41), PNU-292137, IC50 = ...
