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 ...

Lichen-Derived Diffractaic Acid Inhibited Dengue Virus Replication in a Cell-Based System
Molecules, 2023 Dengue is a mosquito-borne flavivirus that causes 21,000 deaths annually. Depsides and depsidones of lichens have previously been reported to be antimicrobials. In this study, our objective was to identify lichen-derived depsides and depsidones as dengue

MicrobiologyOpen, Volume 12, Issue 5, October 2023., 2023 The new Parmelia sulcata genome from the metagenomic sample was evaluated with Hypogymnia physodes and Hypogymnia tubulosa to identify orthologous polyketide synthase (PKS)‐related biosynthetic gene clusters (BGC). The phylogenetic tree highlights the relation of investigated sequences.

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.

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 ...

A Biosynthetic and Taxonomic Atlas of the Global Lichen Holobiont. [PDF]
Environ MicrobiolThis analysis of 794 publicly available lichen shotgun metagenomic datasets, covering 467 unique lichen species from 34 countries, revealed that lichens are complex holobionts. They harbour a variety of fungal, algal, and bacterial players with remarkable biosynthetic capabilities.
