简介内容:4SC-207 is a novel microtubule inhibitor , which shows strong anti-proliferative activity in a large panel of tumor cell lines with an average GI50 of 11 nM. In particular, 4SC-207 is active in multi-drug resistant cell lines, such as HCT-15 and ACHN, suggesting that it is a poor substrate for drug efflux pumps. 4SC-207 inhibits microtubule growth in vitro and in vivo and promotes, in a dose dependent manner, a mitotic delay/arrest, followed by apoptosis or aberrant divisions due to chromosome a
