Scorpinone (1), 3-methyl-6,8-methoxy-2-aza-9,10-anthraquinone, has been isolated from the mycelium of a cultured sterile fungus of Caribbean origin. The structure was elucidated by X-ray crystallography, and 2D NMR spectral data have been assigned. The compound is one of very few known fungal azaanthraquinones.
