Abstract:
:Previously, we focused on a series of 2-aminobenzamide-based histone deacetylase (HDAC) inhibitors, compound 9 of which displayed potent HDAC inhibitory activity against HDAC1 and HDAC2, and moderate anti-proliferative activity against several cancer cell lines. In the current study, we have designed and synthesized a series of novel HDAC inhibitors based on thioether moiety with 9 as a lead compound. Representative compounds12 g and 12 h showed apparently potent anti-proliferative activities against five solid cancer cell lines: A549, HCT116, Hela, A375 and SMMC7721, and low cytotoxicity against NIH 3T3 normal cells. Especially, 12 g and 12 h also revealed potent HDAC inhibitory activity against HDAC1, 2 and 3. In addition, the two compounds could arrest cell cycle in G2/M phase and promote cell apoptosis. Moreover, they showed extended inhibition of colony formation and effectively blocked cell migration towards A549 cancer cells. Furthermore, 12 g and 12 h possessed better pharmacokinetic properties than the lead compound 9. Benefiting from these results, we also explored 12 g and 12 h in the A549 xenografts model for in vivo antitumor activity. The in vivo experiment indicated that 12 g and 12 h could evidently augment antitumor activity (TGI = 56.9% and 62.7% respectively).
