NMK-TD-100 is a novel microtubule modulating agent. NMK-TD-100 blocks mitosis and induces apoptosis in HeLa cells by binding to tubulin. Polymerization of tissue purified tubulin into microtubules was inhibited by NMK-TD-100 with an IC50 value of 17.5±0.35 μM. The binding of NMK-TD-100 to tubulin was estimated to be ~10 times faster than that of colchicine. NMK-TD-100 exerted anti-proliferative activity by disrupting microtubule functions through tubulin binding and provided insights into its potential of being a chemotherapeutic agent. |
