Tubulin polymerization-IN-11 is a potent tubulin polymerization inhibitor with an IC 50 value of 3.4 µM. Tubulin polymerization-IN-11 shows antiproliferative activity. Tubulin polymerization-IN-11 induces Apoptosis and cell cycle arrest at G2/M phase. Tubulin polymerization-IN-11 decreases the expression of cyclin B1, p-cdc2, and Bcl-2 protein levels and increases the expression of cleaved PARP.
