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