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

open access: yesPharmacology 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

Spiromastixones Inhibit Foam Cell Formation via Regulation of Cholesterol Efflux and Uptake in RAW264.7 Macrophages

open access: yesMarine Drugs, 2015
Bioassay-guided evaluation shows that a deep sea-derived fungus, Spiromastix sp. MCCC 3A00308, possesses lipid-lowering activity. Chromatographic separation of a culture broth resulted in the isolation of 15 known depsidone-based analogues, labeled ...

Notes on the circumscription of the lichens Lecanora leprosa and L. sulphurescens (Lecanoraceae, lichenised Ascomycotina) [PDF]

open access: yes, 2013
Lecanora leprosa and L. sulphurescens are two commonly misidentified pantropical lichens. A detailed circumscription is presented to help overcome such difficulties. Both species contain a chemosyndrome of chlorodepsidones based on gangaleoidin.

A computational insight into acetylcholinesterase inhibitory activity of a new lichen depsidone [PDF]

open access: yes, 2014
Acetylcholinesterase (AChE) inhibitors are yet the best drugs currently available for the management of Alzheimer's disease. The recent phytochemical investigation has led to the isolation of a new depsidone 1 with moderate AChE activity (1 mu g).

Lichen and Its Microbiome as an Untapped Source of Anti‐Biofilm Compounds

open access: yesChemistry &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 ...

A new high-performance heterologous fungal expression system based on regulatory elements from the Aspergillus terreus terrein gene cluster [PDF]

open access: yes, 2015
Recently, the Aspergillus terreus terrein gene cluster was identified and selected for development of a new heterologous expression system. The cluster encodes the specific transcription factor TerR that is indispensable for terrein cluster induction. To

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

open access: yesIUBMB 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 ...
