Abstract

In this work, a series of novel 1H-indole-2-carboxylic acid derivatives targeting 14-3-3η protein were designed and synthesized for treatment of liver Cancer. After structural optimization for several rounds, C11 displayed a relatively better affinity with 14-3-3η, as well as the best inhibitory activities against several typical human liver Cancer cell lines, including Bel-7402, SMMC-7721, SNU-387, Hep G2 and Hep 3B cells. Compound C11 also displayed best inhibitory activity against chemotherapy-resistant Bel-7402/5-Fu cells. Besides, C11 was rather safe against hERG and possessed moderate T1/2 and CL values in liver microsomes. In anti-proliferation, trans-well and cell Apoptosis assays, C11 also showed its huge potential as a potent antitumor agent. Then, Western blot assay was conducted, following analyzed by molecular docking, the anti-proliferative mechanisms of this small-molecule inhibitor were revealed. Moreover, C11 was demonstrated to induce G1-S phase cell cycle arrest in liver Cancer cells.
