HUMAN CYCLIN DEPENDENT KINASE 2 COMPLEXED WITH THE INHIBITOR PURVALANOL B
Overview
Selective protein kinase inhibitors were developed on the basis of the, unexpected binding mode of 2,6,9-trisubstituted purines to the adenosine, triphosphate-binding site of the human cyclin-dependent kinase 2 (CDK2)., By iterating chemical library synthesis and biological screening, potent, inhibitors of the human CDK2-cyclin A kinase complex and of Saccharomyces, cerevisiae Cdc28p were identified. The structural basis for the binding, affinity and selectivity was determined by analysis of a three-dimensional, crystal structure of a CDK2-inhibitor complex. The cellular effects of, these compounds were characterized in mammalian cells and yeast. In the, latter case the effects were characterized on a genome-wide scale by, monitoring changes in messenger RNA levels in treated cells with, high-density oligonucleotide probe arrays. Purine libraries could provide, useful tools for analyzing a variety of signaling and regulatory pathways, and may lead to the development of new therapeutics.
