LG308 shows antimicrotubule activity which is a novel synthetic compound. LG308 induces apoptosis, cell death, and significantly suppresses tumor growth that has the potential for the prostate cancer research. LG308 induces arrest of mitotic phase and significantly inhibits progression of G2/M which is associated with the upregulation of cyclin B1 and mitotic marker MPM-2 and the dephosphorylation of cdc2 [1].
