Rosarugosides A and D from Rosa rugosa Flower Buds: Their Potential Anti-Skin-Aging Effects in TNF-α-Induced Human Dermal Fibroblasts [PDF]

open access: yesPlants
This present study investigated the anti-skin-aging properties of Rosa rugosa. Initially, phenolic compounds were isolated from a hot water extract of Rosa rugosa’s flower buds. Through repeated chromatography (column chromatography, MPLC, and prep HPLC),

Lichen and Its Microbiome as an Untapped Source of Anti-Biofilm Compounds. [PDF]

open access: yesChem Biodivers
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 ...

Biosynthesis of Depsides, Depsidones, and Diphenyl Ethers from Fungi and Lichens

open access: yesAsian Journal of Organic Chemistry
Depsides are natural products derived from (poly)phenolic acid derivatives connected by ester bonds. Recent research has revealed crucial molecular mechanisms and distinctive enzymatic chemistry underlying the biosynthesis of depsides, as well as related natural products, such as depsidones and diphenyl ethers.

Lichen Polyphenolic Compounds for the Eradication of Candida albicans Biofilms

open access: yesFrontiers 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

open access: yesFermentation, 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

open access: yesMicrobiology 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.
