| Resumo: |
Bioscreening guided fractionation of the extracts of soft corals Lobophytum crassum and L. rotundum using brine shrimp larvae cytotoxicity assay led to the isolation of a cembranolide diterpene (E,E,E)-6,10,14-trimethyl-3-methylene- 3a,4,7,8,11,12,15,15aoctahydrocylotetradeca [b]furan-2(3H)-one (1). This diterpene, identified as cembranolide compound 1, was found to be active against the multidrug-resistant and chloroquine-sensitive strains of Plasmodium falciparum malaria parasite in vitro. It also possessed cytotoxic properties.
