Few targeted drugs were approved for treatment of colorectal cancer (CRC). Cyclin-dependent kinase 8 played a vital role in regulating transcription and was a key colorectal oncogene associated to colorectal cancer. Here, through de novo drug design and in depth structure–activity relationship analysis, title compound 22, (3-(3-(1H-pyrrolo[2,3-b]pyridin-5-yl)phenyl)-N-(4-methyl-3-(trifluoromethyl)phenyl)propenamide)
很少有靶向药物被批准用于治疗结直肠癌(CRC)。细胞周期蛋白依赖性激酶 8 在调节转录中起重要作用,是与结直肠癌相关的关键结直肠癌基因。在这里,通过从头药物设计和深入的构效关系分析,标题化合物22 , (3-(3-(1 H -pyrrolo[2,3- b ]pyridin-5-yl)phenyl)- N -( 4-methyl-3-(trifluoromethyl)phenyl)propenamide),被发现是一种有效的 II 型 CDK8 抑制剂,它表现出有效的激酶活性,IC 50值 48.6 nM,可显着抑制体内 CRC 异种移植物中的肿瘤生长。进一步的机制研究表明,它可以靶向 CDK8 间接抑制 β-catenin 活性,从而导致 WNT/β-catenin 信号下调并诱导 G2/M 和 S 期细胞周期停滞。更重要的是,标题化合物表现出低毒性和良好的生物利用度 ( F = 39.8
