STRUCTURE OF HUMAN THR160-PHOSPHO CDK2/CYCLIN A COMPLEXED WITH THE INHIBITOR NU6086
OverviewOverview
Aberrant control of cyclin-dependent kinases (CDKs) is a central feature, of the molecular pathology of cancer. Iterative structure-based design was, used to optimize the ATP- competitive inhibition of CDK1 and CDK2 by, O(6)-cyclohexylmethylguanines, resulting in O(6)-cyclohexylmethyl-2-(4'-, sulfamoylanilino)purine. The new inhibitor is 1,000-fold more potent than, the parent compound (K(i) values for CDK1 = 9 nM and CDK2 = 6 nM versus, 5,000 nM and 12,000 nM, respectively, for O(6)-cyclohexylmethylguanine)., The increased potency arises primarily from the formation of two, additional hydrogen bonds between the inhibitor and Asp 86 of CDK2, which, facilitate optimum hydrophobic packing of the anilino group with the, specificity surface of CDK2.
