Abstract: 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), was discovered as a potent type II CDK8 inhibitor, which exhibited potent kinase activity with an IC50 value of 48.6 nM and could significantly inhibit tumor growth in xenografts of CRC in vivo. Further mechanism studies indicated that it could target CDK8 to indirectly inhibit β-catenin activity, which caused downregulation of the WNT/β-catenin signal and inducing cell cycle arrest in G2/M and S phases. More importantly, the title compound exhibited low toxicity with good bioavailability (F = 39.8%). These results could provide the reference for design of new type II CDK8 inhibitors against colorectal cancer.
