生物活性:
Tubulin polymerization-IN-24 (compound HMBA) is a potent tubulin polymerization inhibitor. Tubulin polymerization-IN-24 inhibits MCF-7 cells proliferation. Tubulin polymerization-IN-24 induces apoptosis and cell cycle arrest at G2/M phase. Tubulin polymerization-IN-24 increase the GTP hydrolysis rate and inhibits microtubule assembly.
