Mollicellins O–R, Four New Depsidones Isolated from the Endophytic Fungus Chaetomium sp. Eef-10
Molecules, 2018 Four new depsidones, mollicellins O⁻R (compounds 1⁻4), along with three known compounds 5⁻7, were isolated from cultures of the fungus Chaetomium sp. Eef-10, an endophyte isolated from Eucalyptus exserta.

Lichen Depsidones with Biological Interest [PDF]
Planta Medica, 2021 AbstractDepsidones are some of the most abundant secondary metabolites produced by lichens. These compounds have aroused great pharmacological interest due to their activities as antioxidants, antimicrobial, and cytotoxic agents. Hence, this paper aims to provide up-to-date knowledge including an overview of the potential biological interest of lichen ...

How to build a lichen: from metabolite release to symbiotic interplay
New Phytologist, Volume 238, Issue 4, Page 1362-1378, May 2023., 2023 Summary Exposing their vegetative bodies to the light, lichens are outstanding amongst other fungal symbioses. Not requiring a pre‐established host, ‘lichenized fungi’ build an entirely new structure together with microbial photosynthetic partners that neither can form alone.

Antigenotoxicity of Depsidones Isolated from Brazilian Lichens
Orbital: The Electronic Journal of Chemistry, 2017 Although phenolic compounds produced by lichens have been widely investigated in antitumor assays, only a small number have been evaluated for mutagenicity and genotoxicity.

Two‐step isolation of the two major paraconic acids of Cetraria islandica
Journal of Separation Science, Volume 46, Issue 6, March 2023., 2023 The lichen Cetraria islandica is traditionally used as a demulcent for the symptomatic treatment of irritations of the mouth and throat and associated dry cough, as well as for the treatment of temporary loss of appetite. In addition to depsides and depsidones, thalli contain paraconic acids, a group of secondary metabolites commonly found in lichens ...

ASAP‐MS and DART‐MS as ancillary tools for direct analysis of the lichen metabolome
Phytochemical Analysis, Volume 33, Issue 7, Page 1028-1035, October 2022., 2022 Abstract Introduction Lichens contain unique metabolites that most often need to be characterized from a limited amount of material. While thin layer chromatography is still the preferred analysis method for most lichenologists, liquid chromatography gives a deeper insight in the lichen metabolome, but an extractive step is needed before any analysis ...

Phytochemical Analysis, Volume 33, Issue 7, Page 1111-1120, October 2022., 2022 Abstract Introduction In recent years, LC‐MS has become the golden standard for metabolomic studies. Indeed, LC is relatively easy to couple with the soft electrospray ionization. As a consequence, many tools have been developed for the structural annotation of tandem mass spectra.
