Biosynthesis of Depsides, Depsidones, and Diphenyl Ethers from Fungi and Lichens
Asian Journal of Organic Chemistry, Volume 14, Issue 2, February 2025.Depsides are natural products derived from (poly)phenolic acid derivatives connected by ester bonds. Recent research has revealed crucial molecular mechanisms and distinctive enzymatic chemistry underlying the biosynthesis of depsides, as well as related natural products, such as depsidones and diphenyl ethers.

The role of lichenized algae in the production of Cladonia verticillaris depsidones, revealed by using alginate-immobilized cells [PDF]
, 2015 The mycobiont of the lichen Cladonia verticillaris produces two depsidones, protocetraric and fumarprotocetraric acids, in the nature. This last compound is produced from the former depsidone.

A Novel b-Orcinol Depsidone of Lichen Lobaria pulmonaria [PDF]
Asian Journal of Chemistry, 2014 In continuation of our phytochemical survey of Lobaria pulmonaria has led to the identification of deoxystictic acid in this foliose lichen species for the first time. The isolated β-orcinol depsidone showed moderate anti-hydroxyl radical activity using fluorescence spectroscopy at in vitro conditions.
