Indolequinone derivatives of the antitumour antibiotic BE 10988 were synthesized and evaluated for their cytotoxicity and action mechanism. The quinone system is essential to biological activity and the thiazole ring plays a major role in the poisoning of topoisomerase II. (C) 1999 Elsevier Science Ltd. All rights reserved.

Multistep synthesis (12 steps) of new pentacyclic compounds, which are structurally very close to natural marine alkaloids, was performed via a Diels-Alder reaction between 4-methylene-5-(bromomethylene)-4,5-dihydrothiazole and a protected dioxotryptamine, itself obtained from the commercially available 2,5-dimethoxybenzaldehyde.
