An efficient synthesis of 2-substituted O4-cyclohexylmethyl-5- nitroso-6-aminopyrimidines from 6-amino-2-mercaptopyrimidin-4-ol has been developed and used to prepare a range of derivatives for evaluation as inhibitors of cyclin-dependent kinase 2 (CDK2). The structure-activity relationships (SARs) are similar to those observed for the corresponding O 6-cyclohexylmethoxypurine series with the 2-arylsulfonamide and 2-arylcarboxamide derivatives showing excellent potency. Two compounds, 4-(6-amino-4-cyclohexylmethoxy-5-nitrosopyrimidin-2-ylamino)-N-(2-hydroxyethyl) benzenesulfonamide (7q) and 4-(6-amino-4-cyclohexylmethoxy-5-nitrosopyrimidin-2- ylamino)-N-(2,3-dihydroxypropyl)benzenesulfonamide (7s), were the most potent with IC50 values of 0.7 ± 0.1 and 0.8 ± 0.0 nM against CDK2, respectively. The SARs determined in this study are discussed with reference to the crystal structure of 4-(6-amino-4-cyclohexylmethoxy-5- nitrosopyrimidin-2-ylamino)-N-(2,3-dihydroxypropyl)benzenesulfonamide (7j) bound to phosphorylated CDK2/cyclin A.
