this work, we preliminarily demonstrated the feasibility of CDK9 as a potent target of treatment for colorectal cancer, and a series of novel CDK9 inhibitors were rationally designed and synthesized based on the structure of AZD5438 (a pan CDKs inhibitor reported by AstraZeneca). A novel selective CDK9 inhibitor named CLZX-205, which possessed significant CDK9 inhibitory activity (IC50 = 2.9 nM) with
细胞周期蛋白依赖性激酶 9 (CDK9) 是转录 CDK 亚家族的成员。在本工作中,我们初步论证了CDK9作为结直肠癌治疗的有效靶点的可行性,并基于AZD5438(阿斯利康报道的全CDKs抑制剂)的结构,合理设计并合成了一系列新型CDK9抑制剂。开发了一种名为 CLZX-205 的新型选择性 CDK9 抑制剂,它具有显着的 CDK9 抑制活性 (IC 50 = 2.9 nM),具有可接受的药代动力学特性和体外和体内抗肿瘤功效。机制研究表明,CLZX-205可以通过抑制RNA聚合酶II Ser2位点的磷酸化来诱导HCT116细胞系凋亡,从而抑制凋亡相关基因和蛋白的表达,并在细胞和细胞实验中得到验证。肿瘤组织水平。目前,CLZX-205作为结直肠癌治疗的有希望的候选药物正在进行进一步研究。
