Abstract
Biotransformation studies of 3′,4′‐anhydrovinblastine (1) in Calharanthus roseus cell suspension cultures are reported. A detailed study of one cell line, coded at „916”︁, has revealed that 1 is transformed to the natural bisindole alkaloids leurosine (2) and Catharine (3) in approximately 25–30 and 9–16% yield, respectively. In 24–48 h, about 40% of 1 is utilized by the cells. Conditions for biotransformation of 1 have not been optimized so the above yields quoted are not final.
