Depsides: lichen metabolites active against hepatitis C virus. [PDF]
PLoS ONE, 2015 A thorough phytochemical study of Stereocaulon evolutum was conducted, for the isolation of structurally related atranorin derivatives. Indeed, pilot experiments suggested that atranorin (1), the main metabolite of this lichen, would interfere with the ...

Thermal Decomposition of Lichen Depsides
Zeitschrift für Naturforschung B, 1989 The thermal decomposition of the following lichen depsides has been described: lecanoric acid, gyrophoric acid, evernic acid, perlatolic acid, planaic acid, confluentic acid, atranorin, 4-O-de-methylbarbatic acid, and sekikaic acid. Main reaction products are decarboxylated compounds, phenolic units, rearranged depsides, and xanthones. Triethylammonium

Cytotoxic and cytostatic activity of orcinol-type depsides of lichens
Учёные записки Санкт-Петербургского государственного медицинского университета им. Акад. И.П. ПавловаLichens synthesize unique secondary metabolites, most of which are not found in other living organisms. More than 800 such metabolites are known, which can be found in various parts of the lichen thallus.
