Identification and structure-guided optimization of a series of 4-(pyrazol-4-yl)-pyrimidines as selective CDK4/6 inhibitors is reported herein. Several potency and selectivity determinants were established based on the X-ray crystallographic analysis of representative compounds bound to monomeric CDK6. Significant selectivity for CDK4/6 over CDK1 and CDK2 was demonstrated with several compounds in both enzymatic and cellular assays.
本文报道了一系列 4-(吡唑-4-基)嘧啶类化合物作为选择性 CDK4/6 抑制剂的鉴定和结构引导优化。基于代表化合物与单体 CDK6 结合的 X 射线晶体学分析,确定了几个效力和选择性决定因素。在酶和细胞测定中,几种化合物表现出对 CDK4/6 的显著选择性,优于 CDK1 和 CDK2。
