Common Name

(7r,8r)-7,8-dihydroxy-3,6',8-trimethyl-3,4,6,7-tetrahydrospiro[naphtho[2,3-c]pyran-1,2'-oxane]-4',9-dione

Description

Monascuspirolide B 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. (7r,8r)-7,8-dihydroxy-3,6',8-trimethyl-3,4,6,7-tetrahydrospiro[naphtho[2,3-c]pyran-1,2'-oxane]-4',9-dione was first documented in 2021 (PMID: 34436158). Based on a literature review very few articles have been published on Monascuspirolide B (PMID: 34355225).
