Efforts toward finding potent CDK4 inhibitor for cancer therapy, a series of fluorine substituted pyrrolo[2,3-d]pyrimidine derivatives were designed, synthesized, and evaluated. Among them, the optimal lead compound 18i was discovered with potent activity against CDK4 at the nanomolar level (IC50 =2.5 nM) and exquisite selectivity which demonstrated only modest activity against 3 out of the 394 protein
为了寻找用于癌症治疗的有效 CDK4 抑制剂,设计、合成和评估了一系列氟取代的吡咯并 [2,3-d] 嘧啶衍生物。其中,最佳先导化合物18i被发现具有在纳摩尔水平 (IC 50 = 2.5 nM) 的有效抗 CDK4 活性和精湛的选择性,仅对 394 种蛋白激酶中的 3 种表现出适度的活性。与批准的药物 ribociclib 相比,18i对几种人类癌细胞系表现出更大的体外抗增殖活性。进一步的机制研究表明,18i有效地刺激了 G 1 中的癌细胞周期停滞相并诱导肿瘤细胞凋亡。在乳腺癌异种移植小鼠模型的体内治疗效果比较中,口服18i对ribociclib表现出明显更好的抑制作用,无明显毒性。所有结果都表明18i可能是一种很有前途的 CDK4 抑制剂,用于治疗恶性肿瘤。
