Description

Pungiolide B 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. 12'-acetyl-10'-hydroxy-6,9'-dimethyl-4'-methylidene-5-[(1e)-3-oxobut-1-en-1-yl]-4,6',9,14'-tetraoxaspiro[tricyclo[6.3.0.0³,⁵]undecane-11,13'-tricyclo[8.4.0.0³,⁷]tetradecan]-11'-ene-5',10-dione is found in Xanthium strumarium. 12'-acetyl-10'-hydroxy-6,9'-dimethyl-4'-methylidene-5-[(1e)-3-oxobut-1-en-1-yl]-4,6',9,14'-tetraoxaspiro[tricyclo[6.3.0.0³,⁵]undecane-11,13'-tricyclo[8.4.0.0³,⁷]tetradecan]-11'-ene-5',10-dione was first documented in 2009 (PMID: 19431098). Based on a literature review very few articles have been published on Pungiolide B.

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.
