oline-1,3-(2H,4H)-dione derivatives reported here represents a novel class of potential antitumor agents, which potently and selectively inhibit CDK4 over CDK2 and CDK1. In the benzylamino headpiece, a 3-OH substituent is required on the phenyl ring for CDK4 inhibitory activity, which is further enhanced when an iodo, aryl, heteroaryl, t-butyl, or cyclopentyl substituent is introduced at the C-6 position
此处报道了一系列4-(苄基氨基亚甲基)异喹啉-1,3-(2 H,4 H)-二酮和4-[(吡啶基甲基)氨基亚甲基]异喹啉-1,3-(2 H,4 H)-二酮衍生物代表一类新型的潜在抗肿瘤药,与CDK2和CDK1相比,它有力和选择性地抑制CDK4。在苄基氨基机头,一个3-OH的取代基是必需的苯环为CDK4抑制活性,这是进一步提高上时碘,芳基,杂芳基,吨在异喹啉-1,3-二酮核的C-6位置引入丁基或环戊基取代基。为了规避与酚OH基团的4 -取代的3-OH苯基机头有关的代谢责任,我们采取两种方法:第一,引入氮气ø -或p -在苯环的3-OH基团; 第二,用N-取代的2-吡啶酮代替苯基头基。我们在这里介绍了合成,SAR数据,代谢稳定性数据和CDK4模拟模型,该模型解释了我们的CDK4选择性抑制剂的结合,效能和选择性。
