Effects of Fumarprotocetraric Acid, a Depsidone from the Lichen Cladonia verticillaris, on Tyrosinase Activity

Orbital: The Electronic Journal of Chemistry, 2017
Lichens are widely distributed around the world. Their phenolic compounds, consisting mainly of depsides and depsidones, have been extensively studied for important biological activities.

Functional Traits Mediate Physico‐Chemical Niche Differentiation of Epiphytic Lichens and Bryophytes in Temperate Forests

Journal of Vegetation Science, Volume 37, Issue 2, March/April 2026.
Host tree identity drives bark physico‐chemical filters (e.g., pH, metals) that shape epiphytic communities. We show that species‐specific functional traits, such as lichen substances and bryophyte growth forms, mediate these responses. Lichen metal homeostasis and bryophyte growth habit create distinct species thresholds and community change points ...

Lobaric Acid Exhibits Anticancer Potential by Modulating the Wnt/β‐Catenin Signaling Pathway in MCF‐7 Cells

Pharmacology Research &Perspectives, Volume 13, Issue 4, August 2025.
Effect of lobaric acid on Wnt/β‐catenin pathway in breast cancer. ABSTRACT Lichen secondary metabolites with many remarkable biological activities are used in cancer treatments due to their low side effects and high anticancer potential. In particular, these metabolites constitute an interesting research area in cancer treatments due to their potential

Bioproduction of Depsidones for Pharmaceutical Purposes

, 2011
الأشنات هي تكافلات حميمة وطويلة الأجل محددة من الطحالب الضوئية أو البكتيريا الزرقاء والفطريات غيرية التغذية التي انضمت لتشكيل كيان بيولوجي جديد مختلف عن مكوناته الفردية (جالون وكارديش، 1995). ينتج الكلوروليكين بشكل أساسي مواد فينولية فريدة من نوعها، ديبيد، ديبسيدون وبعض ثنائي بنزوفيوران، مثل أحماض اليوزنيك (Huneck & Yoshimura، 1996)، التي لا تنتجها ...

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.

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 ...

Conventional and innovative approaches to black fungi control for stone heritage preservation

IUBMB Life, Volume 77, Issue 3, March 2025.
Abstract Black Meristematic Fungi (BMF) are characterized by a thick melanized cell wall and an isodiametric cellular expansion. BMF represent one of the most damaging groups of microorganisms causing the deterioration of outdoor exposed stone monuments mainly due to the formation of dark spots and patches leading to the darkening of their surface ...

Chemo-Diversity and Secondary Metabolite Content in Corticolous Crustose Lichens (Fam. Arthoniaceae, Graphidaceae, Pyrenulaceae) from Remnants of Colombian Tropical Dry Forests

Journal of Fungi
Colombia ranks third among South American countries in terms of fungal diversity (including lichens); however, the lichen diversity of tropical dry forest ecosystems, particularly those in the Caribbean region, remains relatively understudied.
