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.

Anti‐Inflammatory Potential of Compounds Isolated from Tunisian Lichens Species
Chemistry &Biodiversity, Volume 19, Issue 8, August 2022., 2022 Abstract The lichen's special symbiotic structure enables it to produce bioactive substances. They have historically been recognized for their aesthetic and medicinal benefits. Furthermore, in recent years, they have performed in various fields, including perfumery, dyeing, and pharmacology due to their rich secondary metabolites.

Ecosphere, Volume 13, Issue 4, April 2022., 2022 Abstract We propose that a qualitative trait approach based on more detailed nuanced traits may reveal previously overlooked patterns, especially when combined with phylogenetic perspectives. By sampling epiphytic lichens and using a functional approach based on nuanced qualitative traits, such as a much greater resolution over photobiont identity ...

Chemical properties of key metabolites determine the global distribution of lichens
Ecology Letters, Volume 25, Issue 2, Page 416-426, February 2022., 2022 In lichen symbioses, secondary metabolites produced by the lichen fungi (mycobionts) provide UV protection on which trebouxioid green algae as the most prominent photobionts sensitively depend. These metabolites differ in their UV absorbance capability and solvability and therefore vary in their propensity of being leached from the lichen body by high ...

Naphthalenones and Depsidones from a Sponge-Derived Strain of the Fungus Corynespora cassiicola
Molecules, 2016 Two new naphthalenones, corynenones A and B (1 and 2), and one new depsidone, corynesidone E (3), together with one known depsidone, corynesidone A (4) and two known diphenyl ethers, corynethers A (5) and B (6), were isolated from the sponge-derived ...

Evidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022 Introduction. Lichens, due to the presence of own secondary metabolites such as depsidones and depsides, became a promising source of health‐promoting organisms with pharmacological activities. However, lichens and their active compounds have been much less studied.

Journal of Chemistry, Volume 2022, Issue 1, 2022., 2022 A new hopan‐type triterpenoic peracid, tinctoride A (1), together with three known compounds, zeorin (2), 6β,22‐dihydroxyhopane (3), and ergosterol peroxide (4), was isolated from Parmotrema tinctorum (Despr. ex Nyl.) Hale. Their chemical structures were identified by extensive 1D and 2D NMR analysis and high‐resolution mass spectroscopy and compared ...

Ecology and Evolution, Volume 11, Issue 24, Page 18615-18632, December 2021., 2021 We investigate species boundaries and the potential for micro‐endemism for a charismatic genus of lichen fungi occurring in Baja California. Genome‐scale data support high species‐level diversity, along with high levels of endemism, while highlighting the problem of delimiting species, particularly in groups with complex, recent phylogeographic ...

Climate‐specific biosynthetic gene clusters in populations of a lichen‐forming fungus
Environmental Microbiology, Volume 23, Issue 8, Page 4260-4275, August 2021., 2021 Summary Natural products can contribute to abiotic stress tolerance in plants and fungi. We hypothesize that biosynthetic gene clusters (BGCs), the genomic elements that underlie natural product biosynthesis, display structured differences along elevation gradients.
