Pelorol from the Tropical Marine Sponge <i>Dactylospongia elegans</i>

Abstract

From the dichloromethane solubles of the tropical marine sponge Dactylospongia elegans, a new aromatic substituted sesquiterpene, pelorol (1), and the known sesquiterpene, ilimaquinone (2), were isolated. The structures of 1 and 2 were deduced from their spectroscopic data. The biological activities of compounds 1 and 2 were assessed in a variety of bioassays, and both compounds were found to have weak antitrypanosomal and antiplasmodial effects.
