Microtubule inhibitor PP-13 is a novel microtubule-destabilizing agent, directly inhibits microtubule assembly by targeting the colchicine-binding site in β-tubulin.PP-13 inhibits the growth of a wide range of cancer cell types, including targeted therapy-resistant and multidrug-resistant (MDR) cell lines (IC50=76-255 nM).PP-13 overcomes the multidrug-resistant (MDR) phenotype in cancer cells, induces mitotic blockade in cancer cells, interferes with both mitotic microtubule organization and spindle pole integrity.PP-13 induces cell prometaphase arrest then asymmetric division or direct apoptotic death.PP-13 reduces tumour growth and metastasis invasion in vivo.
