Abstract

The microbial production, isolation, and structure elucidation of four new napyradiomycin congeners (1-4) is reported. The structures of these compounds, which are new additions to the marine-derived meroterpenoids, were defined by comprehensive spectroscopic analysis and by X-ray crystallography. Using fluorescence-activated cell sorting (FACS) analysis, napyradiomycins 1-4 were observed to induce apoptosis in the colon adenocarcinoma cell line HCT-116, indicating the possibility of a specific biochemical target for this class of cytotoxins.
