It is an antineoplastic agent that exerts its effect by depolymerising microtubules. It has a role as an antineoplastic agent, a tubulin modulator, an antimitotic and a microtubule-destabilising agent. It is a member of thiophenes, a member of benzimidazoles, a carbamate ester and an aromatic ketone."}]
