Description2-[8-(Acetyloxy)-12-hydroxy-2-[2-methyl-3-(prop-1-en-1-yl)oxiran-2-yl]-4,11-dioxo-8,9,10,11-tetrahydro-4H-1-oxatetraphen-5-yl]acetic acid belongs to the class of organic compounds known as naphthopyranones. Naphthopyranones are compounds containing a naphthopyran skeleton where a ring carbon bears a carboxylic acid group. Naphthtopyran is made up of the pyran ring fused to a naphthalene ring system. Kapurimycin A3 is found in Streptomyces sp. It was first documented in 1990 (PMID: 2276971). Based on a literature review very few articles have been published on 2-[8-(acetyloxy)-12-hydroxy-2-[2-methyl-3-(prop-1-en-1-yl)oxiran-2-yl]-4,11-dioxo-8,9,10,11-tetrahydro-4H-1-oxatetraphen-5-yl]acetic acid.
