Tubulin-IN-64 is a sulfonated styrylquinazoline derivative with high selectivity antitumor activity. Tubulin-IN-64 targets tubulin, inhibits the EGFR/Akt/mTOR and EGFR/Ras signaling pathways, induces cell cycle arrest, apoptosis and autophagy. Tubulin-IN-64 exhibits significant antitumor efficacy in the zebrafish GBM xenograft model. Tubulin-IN-64 can be used for the research on glioblastoma and leukemia[1].
