emarginatine F
emarginatine F
A sesquiterpene alkaloid that is a macrolide incorporating a substituted dihydroagarofuran and a pyrindine ring. Isolated from Maytenus emarginata, it exhibits strong cytotoxicity against human epidermoid carcinoma of the nasopharynx (KB), ileocecal adenocarcinoma (HCT-8), melanoma (RPMI-7951) and medulloblastoma (TE-671) tumor cells, and against murine leukemia (P-388).
