Thiocolchicine, a derivative modified in the C Ring of Colchicine (HY-16569) with enhanced biological properties. Thiocolchicine is a potent inhibitor of tubulin polymerization (IC50=2.5 µM) and competitively binds to tubulin with a Ki of 0.7 µM. Thiocolchicine induces cell apoptosis[1][2]. Thiocolchicine can be used as an ADC cytotoxin in ADC technology.

In Vitro	Thiocolchicine is against MCF-7, LoVo, LoVo/DX, A-549 and BALB/3T3 cells with IC50 values of 0.01 μM, 0.021 μM, 0.398 μM, 0.011 μM and 0.114 μM, respectively[3]. Thiocolchicine (1 nM-100 μM; 24-72 hours) shows a relationship between cell cycle blocking activity and growth inhibition in breast cancer cells. It inhibits cell proliferation of MDA-MB-231 and multidrug resistant (MDR) MCF-7 ADRr breast cancer cells with IC50s of 0.6 nM and 400 nM, respectively, as well as MDR CEM-VBL leukemia cells (IC50=50 nM)[2].
