Indibulin is a novel synthetic compound that was identified in a cell-based screening assay to discover cytotoxic drugs. Indibulin destabilizes microtubules and blocks cell cycle transition specifically at the G2-M phase. Indibulin effectively induces apoptosis through Bcl-2 phosphorylation and Bax translocation in human malignant glioma cells in a p53-independent manner. This agent has been shown to be active against multidrug-resistant (MDR) and taxane-resistant tumour cell lines. Indibulin was used in phase I/II clinical trials of patients with advanced solid tumours (metastatic breast cancer). Pharmacokinetic analysis showed a better tolerability underfeeding condition. Dose-limiting toxicities were nausea and vomiting, which seemed to be related to solvent lactic acid.

Sample Use Guides

In Vivo Use Guide

100 mg, 150 mg, 250 mg, 350 mg and 600 mg once daily (QD), 450 mg and 600 mg twice daily (BID). After a washout period, patients received indibulin at the pre-defined daily dose for 14 days every 3 weeks (multiple dose part).

Route of Administration: Oral

In Vitro Use Guide

To examine the cytotoxic effects of indibulin on malignant glioma cells, the four human glioma cell lines, which have different p53 status (U373-MG and T98G have mutated p53, and U87-MG and D54 have wild-type p53), were treated with different concentrations of indibulin for 2 days. The viability of all cell lines was reduced in a dose-dependent manner. The IC50s for indibulin in U373-MG, T98G, U87-MG, and D54 cells were 150, 180, 120, and 190 nM, respectively.
