Design, synthesis and biological studies of novel tubulin inhibitors
摘要:
A series of compounds originally derived from the vascular endothelial growth factor receptor tyrosine kinase inhibitor, SU5416, were synthesized and evaluated. The most potent compound in this series, compound 3, which structurally resembles the potent anti-microtubule agent combretastatin A-4, inhibited tubulin polymerization and showed potent growth inhibitory activities on both prostate and breast cancer lines with IC50 values in the low nanomolar range.

antiproliferative activity with IC50 in the range of 0.19-0.51 μM. The compound inhibited tubulin polymerization and disrupted the microtubule network, leading to G2/M phase arrest. Furthermore, compound 12 induced ROS production and malfunction of mitochondrial membrane potential. Compound 12 led to cancer cells apoptosis in a dose-dependent manner. Westernblotanalysis showed that compound 12 induced up-regulation
