Description: Avanbulin, also known as BAL27862, is a novel synthetic potent inhibitor of tubulin polymerization that induces cancer cell death. BAL27862 is a novel microtubule-destabilizing drug that is currently undergoing phase I clinical evaluation as the prodrug BAL101553. BAL27862 elicits a unique microtubule (MT) phenotype, distinct from paclitaxel, vinblastine and colchicine, has broad in vitro anti-proliferative activity against a diverse range of human tumor lines (low nM IC50s) and induces significant antitumor responses in a range.

Additional Information

BAL27862 is a novel MTA that triggers apoptosis in cancer cells. In vitro, BAL27862 destabilizes microtubules to produce a microtubule phenotype distinct from that observed with other MTAs, and retains its antiproliferative activity against P-gp overexpressing tumor cells. BAL27862, when administered intravenously or orally, induces significant antitumor responses in a range of animal models of human cancer, including tumors refractory to conventional treatments. BAL27862 overcomes P-gp overexpression-mediated resistance, and demonstrate that Bcl-2 status and tubulin modifications do not necessarily affect its antitumor activity. Analysis of MDs shows that BAL27862 elicited effects consistent with its destabilizing activity; suppression of MDs was 2-fold lower than observed with PTX. Strikingly, BAL27862 displayed a unique microtubule severing activity. Conclusions: Besides its microtubule-targeting activity, BAL27862 displays unique features in its mechanism of action that make it a promising compound for clinical investigation.  (source: J Clin Oncol 28, 2010 (suppl; abstr e13589)
