MedKoo CAT#: 412445

CAS#: 2645-61-6 (HCl)

Description: Catharanthine hydrochloride is the salt from of Catharanthine (free base), a terpene indole alkaloid produced by the medicinal plant Catharanthus roseus and Tabernaemontana_divaricata. Catharanthine is derived from strictosidine, but the exact mechanism by which this happens is currently unknown. Catharanthine is an indole moiety of dimeric vinca alkaloids vinblastine & vincristine.
