    Abstract:
    A novel series of resveratrol-cinnamoyl hybrids as tubulin polymerization inhibitors were designed and synthesized, and evaluated for their anti-proliferative activities against A549, MCF-7, HepG2, HeLa and MDA-MB-231 five cancer cell lines. Most designed compounds showed better anti-proliferative activities. Particularly, compound 6h exhibited the potent anti-proliferative activities with the IC50 value of 0.12, 0.016, 0.44, 0.37 and 0.78 μΜ against A549, MCF-7, HepG2, HeLa and MDA-231, respectively, which was superior to that of reference drug colchicine. Besides, compound 6h displayed a remarkable inhibition of tubulin polymerization and a great potency to compete with [3H] colchicine in binding to tubulin. Further studies indicated that compound 6h could induce the MCF-7 cells arrest in the G2/M phase. What' more, compound 6h induced cell apoptosis in a dose-dependent manner, and regulated the expression level of apoptosis-related proteins. These results revealed that compound 6h is a promising tubulin polymerization inhibitor for treatment of cancer and it is worthy of further exploitation.
