Description

Xanthalongin belongs to the class of organic compounds known as xanthanolides. These are sesquiterpenoids with a structure based on the xanthanolide skeleton consistsing of a cycloheptane ring usually attached to a four-carbon chain (at carbon 1 ) and a methyl group (at carbon 10), and fused to a five-member lactone ring (sharing carbons 7 and 8). The lactone ring can be conjugated with a methyl or methylene group at position 11. (3ar,7r,8ar)-7-methyl-3-methylidene-6-(3-oxobutyl)-3ah,4h,7h,8h,8ah-cyclohepta[b]furan-2-one is found in Arnica longifolia, Dittrichia graveolens and Inula japonica. (3ar,7r,8ar)-7-methyl-3-methylidene-6-(3-oxobutyl)-3ah,4h,7h,8h,8ah-cyclohepta[b]furan-2-one was first documented in 2008 (PMID: 18981602). Based on a literature review a small amount of articles have been published on Xanthalongin (PMID: 32360461) (PMID: 34879619) (PMID: 18975264).

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as xanthanolides. These are sesquiterpenoids with a structure based on the xanthanolide skeleton consistsing of a cycloheptane ring usually attached to a four-carbon chain (at carbon 1 ) and a methyl group (at carbon 10), and fused to a five-member lactone ring (sharing carbons 7 and 8). The lactone ring can be conjugated with a methyl or methylene group at position 11.
