Tubulin polymerization-IN-4 is a potent tubulin polymerization inhibitor with IC50 value of 4.6 μM. Tubulin polymerization-IN-4 can disrupt tubulin polymerization and vasculature, arrest the cell cycle at the G2/M phase, induce apoptosis, and suppress clonogenesis and migration in HeLa cells. Tubulin polymerization-IN-4 can be used for researching cervical cancer[1].

Tubulin polymerization-IN-4 (compound 9j) (0-1 μM; 48 hours) exhibits sub-micromolar inhibitory activities against HeLa, SiHa and MS751[1].
Tubulin polymerization-IN-4 (3, 6 and 12.5 μM; 0-20 min) inhibits tubulin polymerization in a concentration-dependent manner with the inhibition percentages of 39%, 54%, and 77% at 3, 6 and 12.5 μM[1].
Tubulin polymerization-IN-4 (1-100 μM; 2 hours) inhibits the formation of EBI-β-tubulin adduct in a concentration-dependent manner[1].
Tubulin polymerization-IN-4 (0.2 μM; 1 and 2 hours) disrupts the HUVEC-formed vascular tube[1].
Tubulin polymerization-IN-4 (0.1-0.4 μM; 24 hours) increases cell distribution to the G2/M phase in a concentration-dependent manner[1].
Tubulin polymerization-IN-4 (0.1-0.4 μM; 24 hours) induces apoptosis of HeLa cells[1].
