Cathagines A–D, new bisindole alkaloids from Catharanthus roseus

Journal of Natural Medicines
Four new bisindole alkaloids, cathagines A (1)-D (4) consisting of an aspidosperma and the fused tetracyclic 3-spirooxindole derived from an iboga type skeleton were isolated from the whole plant of Catharanthus roseus. The structures including absolute stereochemistry were elucidated on the basis of 2D NMR data and CD spectra.

Novel Bisindole Derivatives Of Catharanthus Alkaloids With Potential Cytotoxic Properties

2003
Pantropical 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.
