New Bisindole Alkaloids from Tabernaemontana corymbosa
Journal of Natural Products, 2002Ten new bisindole alkaloids of the vobasinyl-ibogan type, viz., conodiparines A-F (1-6), conodutarines A and B (7, 8), and cononitarines A and B (9, 10), were obtained from the leaf extract of the Malayan species Tabernaemontana corymbosa. The structures were determined using NMR and MS analysis.

Syntheses of the Bisindole Alkaloids of the Genera Borreria and Flindersia
2014Abstract The flinderoles and their structural isomers, the borreverines, have intriguing chemical structures and promising biological activity. These indole alkaloids each contain multiple stereocenters that challenge synthetic chemists to develop new reaction methods. Proven antimalarial activity further established the synthesis of these targets as

Novel Bisindole Derivatives Of Catharanthus Alkaloids With Potential Cytotoxic Properties
2003Pantropical plant Catharanthus roseus (L) G. Don is known as a source of valuable bisindole alkaloids: vinblastine (VBL) and vincristine (VCR), oncolytics widely used as sulfates in therapy of malignant diseases. They are biosynthesized in the plant from monoindolic vindoline and catharanthine, both derived from L-tryptophan and loganine units.

Insecticidal bisindole alkaloids from leaves of Tabernaemontana divaricata 'Dwaft'
PhytochemistrySix undescribed bisindole alkaloids, namely taberdisines A-F (1-6), were isolated from the leaves of Tabernaemontana divaricata 'Dwaft'. Among them, alkaloids 1 and 2 were the first examples of strychnos-iboga type alkaloid with both C-C linkage patterns. Alkaloid 3, a new type of aspidosperma-iboga with a furan-ring, as well as other three undescribed
