| Abstract: | Cribrarione A (1), a new dihydrofuranonaphthoquinone pigment with antimicrobial activity against Bacillus subtilis has been isolated from a myxomycete Cribraria purpurea and its structure was elucidated by spectral data. The 1H-13C long-range couplings through an intramolecular hydrogen bond were clearly observed in the HMBC spectrum of 1. |
