Phenolic Acids and Depsides from Some Species of the Erodium Genera [PDF]
Zeitschrift für Naturforschung C, 2001 Abstract Six natural polyphenolic compounds, brevifolin carboxylic acid, brevifolin, ellagic acid, methyl gallate, gallic acid and protocatechuic acid have been isolated from the methanol extract of the whole plant of Erodium cicutarium (L.) L.’Herit. (Geraniaceae).

Synthesis of the Lichen Depsides Miriquidic Acid and Normiriquidic Acid
, 1986 The total synthesis of the lichen depsides miriquidic acid (1) and normiriquidic acid (2) is reported. The latter depside has been shown to co-occur with miriquidic acid in the lichen Lecidea leucophaea ( Flk .) Nyl .

A Biosynthetic and Taxonomic Atlas of the Global Lichen Holobiont
Environmental Microbiology, Volume 27, Issue 6, June 2025.This 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.

Archiv der Pharmazie, Volume 358, Issue 5, May 2025.The potential therapeutic effects of evernic acid (EA) were investigated using functional in vitro assays and the evaluation of gene and protein expression levels on ovarian cancer cell lines. EA demonstrated antiproliferative effects on ovarian cancer cells, primarily through the activation of apoptosis at both cellular and molecular levels.

Herbicidal and Plant-growth Stimulating Effects of Phenolic Compounds Isolated from Lichens
Orbital: The Electronic Journal of Chemistry, 2015 The depsides atranorin (7) and diffractaic acid (1), the depsidones hypostictic (2) protocetraric (3), salazinic (4) acids, the xanthone secalonic acid (5), and usnic acid (6) were evaluated for their phytotoxic potentials against the target species ...

Tyrosinase Inhibition Activities of Depsides Isolated from Ramalina Species
, 2023 Three depsides, namely sekikaic acid (1), homosekikaic acid (2), and 4′-O-demethylsekikaic acid (3) were isolated from acetone fraction of Ramalina spp. The structures were characterized by using spectroscopic techniques like 1H NMR, 13C NMR, ESI MS and ...

Lichen and Its Microbiome as an Untapped Source of Anti‐Biofilm Compounds
Chemistry &Biodiversity, Volume 22, Issue 4, April 17, 2025.Lichens and their associated fungi give rise to the evaluation of several extracts and compounds against biofilms. ABSTRACT Lichen substances have been first described in the 1870s, and around 10 000 compounds have been isolated and characterized. Most of them have been evaluated for their activity on planktonic microorganisms (bacteria and fungi ...
