of ceric ammonium nitrate (CAN) was developed. Under the optimized reaction conditions, we synthesized a new series of amide anhydrovinblastine analogs substituted at the vindoline moiety of C-23 site and, evaluated for their proliferation inhibition against HeLa cell. The aryl-substituted derivatives showed loss of potency, while alkyl-substituted derivatives retained some of its cytotoxic potency

Studies involving plant tissue cultures of Catharanthus roseus are described. Investigations concerning the propagation of cell lines of this plant for the purposes of producing indole alkaloids within the Corynanthé, Aspidosperma and Iboga families are presented. The utilization of such tissue culture systems for studies in biosyntheses and isolation of enzymes are also discussed.

A 10′-fluoro-vinca alkaloid compound or its pharmaceutically acceptable salt is disclosed, as are methods of its preparation and use. A disclosed 10′-fluoro-vinca alkaloid compound has better cytotoxic potency against leukemia and cancer cell lines, and is about 8-times more cytotoxic to a multiple drug resistant cancer cell line than is a parental 10′-unsubstituted vinca alkaloid.
