To develop novel CDK2 inhibitors as anticancer agents, a series of novel pyrimidine-based benzothiazole derivatives were designed and synthesized. Initial biological evaluation demonstrated some of target compounds displayed potent antitumor activity in vitro against five cancer cell lines. Especially, the analogue 10s exhibited approximately potency with AZD5438 toward four cells including HeLa, HCT116
为了开发作为抗癌剂的新型CDK2抑制剂,设计并合成了一系列新型的基于嘧啶的苯并噻唑衍生物。初步的生物学评估表明,某些目标化合物在体外对五种癌细胞系表现出有效的抗肿瘤活性。尤其是,类似物10s的AZD5438对包括HeLa,HCT116,PC-3和MDA-MB-231在内的四个细胞的IC 50值分别为0.45、0.70、0.92、1.80μM表现出大约效力。更有趣的是,这项研究中活性最高的化合物10s还具有令人鼓舞的CDK2 / cyclin A2抑制活性,IC 50值15.4 nM,几乎是阳性对照AZD5438的3倍,分子对接研究表明该类似物与CDK2结合位点有效结合。进一步的研究表明,化合物10s可以以浓度依赖的方式诱导细胞周期停滞和凋亡。这些观察结果表明嘧啶-苯并噻唑杂合体代表了一类新的CDK2抑制剂,非常值得进一步研究,以产生潜在的抗癌药。
