Vindoline Products | Cleanchem - Vindoline is a natural alkaloid derived from the Madagascar periwinkle plant (Catharanthus roseus). Although not used therapeutically on its own, it serves as a chemical precursor in the biosynthesis of other important anticancer drugs like vinblastine and vincristine. Its structure contributes to the cytotoxic properties of these agents by affecting tubulin polymerization. Vindoline is of significant interest in pharmacognosy and natural product chemistry.
