Tubulin polymerization-IN-76

Tubulin polymerization-IN-76 (compound 20b) is a potent and orally active Tubulin polymerization inhibitor. Tubulin polymerization-IN-76 inhibits Tubulin polymerization with an IC50 of 2.505 μM by acting on the colchicine binding site, thereby disrupting intracellular Microtubule networks and interfering with cell mitosis. Tubulin polymerization-IN-76 demonstrates exceptional efficacy against MGC-803 and HGC-27 cells with IC50s of 1.61 and 1.82 nM, respectively. Tubulin polymerization-IN-76 effectively inhibits the colony formation and cell migration activities, and induces G2/M phase cycle arrest and Apoptosis in MGC-803 and HGC-27 cells.Tubulin polymerization-IN-76 shows a broad-spectrum antiproliferative activity[1].
