Tubulin-based structure-affinity relationships for antimitotic Vinca alkaloids.

Abstract

The Vinca alkaloids are a group of widely used anticancer drugs, originally extracted from the Madagascar periwinkle, that disrupt microtubule dynamics in mammalian cells by interfering with proper assembly of α,β-tubulin heterodimers. They favor curved tubulin assemblies that destabilize microtubules and induce formation of spiral aggregates. Their binding… (More)
