Bisindole alkaloids of the vobasine-iboga type, conodiparines A-D obtained from Tabernaemontana corymbosa exhibited cytotoxicity [IC50 (μg/mL) = 18.6–19.2] and reversed resistance [IC50 (μg/mL) = 13.5–17] in vincristine-sensitive and resistant KB cells, respectively [62]. Aspidosperma typ...
A process for the preparation of diindolealkaloids, especially new compounds corresponding to vinblastine or leurosine, in which the N- methyl group is replaced by an N--CH.sub.2 --OC.sub.2 H.sub.5 group having antitumor properties. The starting compounds are subjected to oxidation by chrom...

Marine environments are a rich source of indole and bisindole alkaloids of great structural variety. In the absence of traditional use, the chemical constituents of marine organisms are separated following bioassay-guided fractionation, and, consequently, contrary to compounds from terrestrial sources, ...
as fractions of this species displayed interesting cytotoxic bioactivities and chemical profiles. The first chemical investigation of this marine species led to the discovery of two new bisindole alkaloids of the topsentin family, together with six other known indole alkaloids. Missing the usual centra...
