by the synthesis and evaluation of 45 N(2)-substituted analogues of NU2058. These studies have confirmed the requirement for the hydrogen bonding N(2)-NH group and the requirement for an aromatic N(2)-substituent to confer potency in the series. Additional potency is conferred by the presence of a group capable of donating a hydrogen bond at the 4'-position, for example, the 4'-hydroxy derivative (25
5'-三磷酸腺苷(ATP)竞争性细胞周期蛋白依赖性激酶抑制剂O(6)-环己基甲基鸟嘌呤(NU2058,1)已被用作基于结构的药物发现程序的先导,导致发现了有效的CDK1和- 2种抑制剂NU6102(3,IC(50)= 9.5 nM和5.4 nM分别相对于CDK1 / cyclinB和CDK2 / cyclinA3)。通过合成和评估NU2058的45个N(2)取代类似物,进一步探索了该系列的SAR。这些研究已经证实了氢键N(2)-NH基团的要求和芳香N(2)-取代基的要求,以赋予该系列效力。可以通过在4'-位上提供氢键的基团(例如4'-羟基衍生物(25,与CDK1 / cyclinB和CDK2 / cyclinA3相比IC(50)分别为94 nM和69 nM),4'-单甲基磺酰胺衍生物(28,与CDK1 / cyclinB和CDK2 / cyclinA3相比IC(50)= 9 nM和7.0 nM
