Anti‐Inflammatory Potential of Compounds Isolated from Tunisian Lichens Species

open access: yesChemistry &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.

Nuanced qualitative trait approaches reveal environmental filtering and phylogenetic constraints on lichen communities

open access: yesEcosphere, 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

open access: yesEcology 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 ...

Depside and Depsidone Synthesis in Lichenized Fungi Comes into Focus through a Genome-Wide Comparison of the Olivetoric Acid and Physodic Acid Chemotypes of Pseudevernia furfuracea

open access: yesBiomolecules, 2021
Primary biosynthetic enzymes involved in the synthesis of lichen polyphenolic compounds depsides and depsidones are non-reducing polyketide synthases (NR-PKSs), and cytochrome P450s.

Fungal Depsidones Stimulate AKT-Dependent Glucose Uptake in 3T3-L1 Adipocytes. [PDF]

open access: yesJ Nat Prod
Enhanced glucose uptake in insulin-sensitive tissues is one of the therapeutic strategies to ameliorate hyperglycemia and maintain glucose homeostasis in type 2 diabetes.

Phytochemical Characterization and Pharmacological Properties of Lichen Extracts from Cetrarioid Clade by Multivariate Analysis and Molecular Docking

open access: yesEvidence-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.

Tinctoride A, a New Hopan‐Type Triterpenoic Peracid from the Thallus of Lichen Parmotrema Tinctorum (Despr. ex Nyl.) Hale

open access: yesJournal 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 ...

Species boundaries in the messy middle—A genome‐scale validation of species delimitation in a recently diverged lineage of coastal fog desert lichen fungi

open access: yesEcology 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

open access: yesEnvironmental 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.

Cytotoxic and antibacterial depsidones from the endophytic fungus Chaetomium brasiliense isolated from Thai rice

open access: yes, 2021
Four new depsidones, mollicellins V-Y (1-4), together with eight known depsidones (5-12) were isolated from the endophytic fungus, Chaetomium brasiliense, detached from stems of Thai rice.
