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 ...

Lichen Polyphenolic Compounds for the Eradication of Candida albicans Biofilms

Frontiers in Cellular and Infection Microbiology, 2021
Lichens, due to their symbiotic nature (association between fungi and algae), constitute a chemical factory of original compounds. Polyphenolic compounds (depsides and depsidones) are the main constituents of lichens and are exclusively biosynthesized by

Comparison of Aqueous and Lactobacterial-Fermented Mercurialis perennis L. (Dog’s Mercury) Extracts with Respect to Their Immunostimulating Activity

Fermentation, 2023
Lactic acid (LA) fermentation of dog’s mercury (M. perennis L.) herbal parts was investigated in samples inoculated with either Lactobacteria (Lactobacillus plantarum and Pediococcus pentosaceus, LBF) or whey (WF).

A Candidate Gene Cluster for the Bioactive Natural Product Gyrophoric Acid in Lichen-Forming Fungi

Microbiology Spectrum, 2022
Natural products of lichen-forming fungi are structurally diverse and have a variety of medicinal properties. Despite this, they have limited implementation in industry mostly because the corresponding genes are unknown for most of their natural products.

Anti-cancer Evaluation of Depsides Isolated from Indonesian Folious Lichens: Physcia millegrana, Parmelia dilatata and Parmelia aurulenta

Biomolecules, 2020
Cancer is a serious health burden on global societies. The discovery and development of new anti-cancer therapies remains a challenging objective. Although it has been shown that lichen secondary metabolites may be potent sources for new anti-cancer ...

Two New Fumarprotocetraric Acid Lactones Identified and Characterized by UHPLC-PDA/ESI/ORBITRAP/MS/MS from the Antarctic Lichen Cladonia metacorallifera

Separations, 2022
Lichens are symbiotic organisms between algae and fungi, which are makers of secondary compounds named as lichen substances. Hyphenated techniques have significantly helped natural product chemistry, especially UHPLC/ESI/MS/MS in the identification ...

Fungal Depsides—Naturally Inspiring Molecules: Biosynthesis, Structural Characterization, and Biological Activities

Metabolites, 2021
Fungi represent a huge reservoir of structurally diverse bio-metabolites. Although there has been a marked increase in the number of isolated fungal metabolites over the past years, many hidden metabolites still need to be discovered.

Biosynthesis of the C-Glycosylated Depside Arenicolin B. [PDF]

Chembiochem
AbstractWe uncovered the biosynthetic pathway of the C‐glycosylated depside arenicolin B from Phialomyces arenicola through genome mining, heterologous reconstitution and biochemical characterization. The biosynthetic gene cluster (BGC) of arenicolin B is comprised of a HRPKS, a NRPKS, and a C‐glycosyltransferase.

The chemistry of Pseudocyphellaria impressa S. Lat. in New Zealand [PDF]

, 1979
As part of a detailed study of the nomenclature and taxonomy of the New Zealand species of Pseudocyphellaria it has been noted that the chemistry of the P. impressa (Hook & Taylor) Vainio aggregate, that is species with a markedly faveolate (honeycomb-
