Conodiparines A-D, new bisindoles from Tabernaemontana. Reversal of vincristine-resistance with cultured cells

Bioorg Med Chem Lett. 1998 Jul 7;8(13):1693-6. doi: 10.1016/s0960-894x(98)00294-7.

Abstract

Four new bisindoles of the vobasine-iboga type, conodiparines A-D were obtained from Tabernaemontana corymbosa which showed appreciable activity in reversing resistance in vincristine-resistant KB cells.
