Xanthanolides

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.
