  2-Anilino-4-(thiazol-5-yl)pyrimidine CDK Inhibitors:  Synthesis, SAR Analysis, X-ray Crystallography, and Biological Activity

  摘要：

  Following the identification through virtual screening of 4-(2,4-dimethyl-thiazol-5-yl)pyrimidin-2-ylamines as moderately potent inhibitors of cyclin-dependent kinase-2 (CDK2), a CDK inhibitor analogue program was initiated. The first aims were to optimize potency and to evaluate the cellular mode of action of lead candidate molecules. Here the synthetic chemistry, the structure-guided design approach, and the structure-activity relationships (SARs) that led to the discovery of 2-anilino-4-(thiazol-5-yl)pyrimidine ATP-antagonistic CDK2 inhibitors, many with very low nM K(i)s against CDK2, are reported. Furthermore, X-ray crystal structures of four representative analogues from our chemical series in complex with CDK2 are presented, and these structures are used to rationalize the observed biochemical SARs. Finally results are reported that show, using the most potent CDK2 inhibitor compound from the current series, that the observed antiproliferative and proapoptotic effects are consistent with cellular CDK2 and CDK9 inhibition.

  compounds were in fact potent inhibitors of aurora A and B kinases. It was shown that potency and selectivity of aurora kinase inhibition correlated with the presence of a substituent at the aniline para-position in these compounds. The anticancer effects of lead compound 4-methyl-5-(2-(4-morpholinophenylamino)pyrimidin-4-yl)thiazol-2-amine (18; Ki values of 8.0 and 9.2 nM for aurora A and B, respectively)

  通过对我们的激酶导向化合物集合的基于细胞的筛选，我们发现N-苯基-4-(噻唑-5-基)嘧啶-2-胺的一个子集是针对癌细胞系的有效细胞毒剂，抑制有丝分裂组蛋白 H3磷酸化，并导致异常的有丝分裂表型。随后证实，这些化合物实际上是极光 A 和 B 激酶的有效抑制剂。结果表明，极光激酶抑制的效力和选择性与这些化合物中苯胺对位取代基的存在相关。先导化合物4-甲基-5-(2-(4-morpholinophenylamino)pyrimidin-4-yl)thiazol-2-amine ( 18 ; K i ) 的抗癌作用极光 A 和 B 的值分别为 8.0 和 9.2 nM) 显示来自有丝分裂失败后的细胞死亡和由于细胞抑制极光 A 和 B 激酶而增加的多倍性。初步体内评估表明，化合物18具有口服生物利用度并具有抗癌活性。化合物18 (CYC116) 目前正在癌症患者中进行 I 期临床评估。
