Abstract
Novel 3',4'-dehydro- and 4'-deoxo-vincristine and vinblastine compounds are obtained by coupling an indole unit of the catharanthine series and a dihydroindole unit of the vindoline series. Representative compounds of this series showed superior results when tested for activity against L1210 and P388 mouse leukemia.
