RESUMO

As a continuation of our research on developing potent and potentially safe anti-proliferative agents, two series of novel Jiyuan Oridonin A-1,2,3-triazole-azole hybrids were designed, synthesized and evaluated for their anti-proliferative activity against four selected cancer cell lines (MGC-803, MCF-7, PC-3, Eca-109). Some compounds with better growth inhibitory effects were chosen to carry out further studies in A549 and SMMC-7721. Most of the synthesized compounds exhibited moderate to good activity against all the cancer cell lines selected. Particularly, the most active agent 8b showed high potency against human cancer cells with IC50 ranging from 0.2 ±â€¯0.0 to 5.0 ±â€¯0.9 µM. Cellular mechanism studies elucidated compound 8b arrests cell cycle at G1 phase and induce a strong apoptotic response in SMMC-7721 cells. Furthermore, 8b could inhibit the colony formation and migration via Wnt signaling pathway in SMMC-7721 cells. For all these reasons, compound 8b holds promising potential as anti-proliferative agent.
