Abstract

A D-ring contracted analogue of the strongly cytotoxic marine pyrrole alkaloid lamellarin D was synthesized and investigated for its antiproliferative action towards a wild type and a multidrug resistant (MDR) Cancer cell line. The compound was found to inhibit tumor cell growth at submicromolar concentrations and showed a lower relative resistance in the MDR cell line than the antitumor drug camptothecin to which lamellarin D shows cross resistance and with which lamellarin D shares the same binding site.
