Abstract: Pestalafuranones A–E (compounds 1–5), five new 2(5H)-furanones, have been isolated from cultures of an isolate of Pestalotiopsis besseyi. The structures of these compounds were elucidated mainly by analysis of their NMR spectroscopic data and HRESIMS experiments. Pestalafuranones A–C (compounds 1–3) displayed weak inhibitory effects against HIV-1 replication in C8166 cells, whereas pestalafuranones D (4) and E (5) showed moderate antifungal activity against the plant pathogens Verticillium dahiae and Alternaria longipes.
Keywords: pestalafuranones A–E; endophytes; Pestalotiopsis besseyi; bioactivity
