STRUCTURE OF HUMAN THR160-PHOSPHO CDK2/CYCLIN A COMPLEXED WITH A 2-ARYLAMINO-4-CYCLOHEXYLMETHYL-5-NITROSO-6-AMINOPYRIMIDINE INHIBITOR
|
OverviewOverview
A series of O(4)-cyclohexylmethyl-5-nitroso-6-aminopyrimidines bearing, 2-arylamino substituents was synthesised and evaluated for CDK1 and CDK2, inhibitory activity. Consistent with analogous studies with, O(6)-cyclohexylmethylpurines, 2-arylaminopyrimidines with a sulfonamide or, carboxamide group at the 4'-position were potent inhibitors, with IC(50), values against CDK2 of 1.1+/-0.3 and 34+/-8 nM, respectively. The crystal, structure of the 4'-carboxamide derivative, in complex with phospho-Thr160, CDK2/cyclin A, confirmed the expected binding mode of the inhibitor, and, revealed an additional interaction between the carboxamide function and an, aspartate residue.
