Definition:An azaphilone that is 1H-isochromene-6,8(7H,8aH)-dione substituted by a prop-1-en-1-yl group at position 3, hydroxy groups at positions 1 and 8a, a methyl group at position 7 and a (3,4,6-trihydroxy-2-methylbenzoyl)oxy group at position 7. It has been isolated from Penicillium purpurogenum.
Synonyms:exact_synonym: (1S,7R,8aS)-1,8a-dihydroxy-7-methyl-6,8-dioxo-3-[(1E)-prop-1-en-1-yl]-6,7,8,8a-tetrahydro-1H-isochromen-7-yl 3,4,6-trihydroxy-2-methylbenzoate
