Penostatins F–I, novel cytotoxic metabolites from a Penicillium species separated from an Enteromorpha marine alga
Abstract
Penostatins F–I have been isolated from a strain of Penicillium sp. originally separated from the marine alga Enteromorpha intestinalis, and their stereostructures have been established on the basis of spectral analyses. All the compounds exhibit significant cytotoxicity against cultured P388 cells.
