catharanthine/卵巣腫瘍

Navelbine (NVB, vinorelbine tartrate) is a semisynthetic Vinca alkaloid in which the catharanthine moiety contains an eight-membered ring in place of the nine-membered ring that is present in all naturally occurring members of the vinblastine group. This modification selectively reduces interaction

Vinorelbine is a new semisynthetic vinca alkaloid that differs chemically from vinblastine by a substitution of the catharanthine moiety. The powerful cytostatic activity of vinorelbine against murine tumors, human malignant cell lines and human tumor xenografts in nude mice has been demonstrated.
