Synthesis and biological evaluation of a D-ring-contracted analogue of lamellarin D

Bioorg Med Chem. 2017 Nov 15;25(22):6137-6148. doi: 10.1016/j.bmc.2017.02.005. Epub 2017 Feb 9.

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.

Keywords: Alkaloid synthesis; Antitumor activity; Molecular docking; Natural product mimetics; Transition metal catalysis.
