Novel, male-produced aggregation pheromone of the cerambycid beetle Rosalia alpina, a priority species of European conservation concern.

PLoS ONE, 2017
Several recent studies have demonstrated the great potential for exploiting semiochemicals in ecology and conservation studies. The cerambycid beetle Rosalia alpina represents one of the flagship species of saproxylic insect biodiversity in Europe.

Bioactive Alpha-Pyrone and Phenolic Glucosides from the Marine-Derived Metarhizium sp. P2100

Journal of Fungi, 2022
Glycoside compounds have attracted great interest due to their remarkable and multifarious bioactivities. In this study, four hitherto unknown 4-methoxy-β-D-glucosyl derivatives were obtained and identified from the marine-derived fungus Metarhizium sp ...

Caffeylpyruvate hydrolase from the bioluminescent fungus Neonothopanus gardneri is the key recycling enzyme in the fungal bioluminescence pathway

The FEBS Journal, EarlyView.
Caffeic acid is a central metabolite in the fungal bioluminescence pathway. We identified and characterized caffeylpyruvate hydrolase from Neonothopanus gardneri (ngarCPH) and demonstrate its ability to hydrolyze fungal oxyluciferin into caffeic and pyruvic acids, confirming a complete and self‐sustained fungal bioluminescence cycle.

Iron Complexes With Proteins, Carbohydrates, and Maillard Products in Dairy Systems: Implication for Fortification, Bioavailability, and Product Functionality

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 4, July 2026.
ABSTRACT The global prevalence of iron (Fe) deficiency anemia (IDA) continues to pose major public health challenges, necessitating the development of effective fortification strategies. Dairy‐based systems are promising vehicles for Fe fortification and delivery due to their widespread consumption and nutritional value, although their complex matrix ...

A novel and widespread class of ketosynthase is responsible for the head-to-head condensation of two acyl moieties in bacterial pyrone biosynthesis

Beilstein Journal of Organic Chemistry, 2015
The biosynthesis of photopyrones, novel quorum sensing signals in Photorhabdus, has been studied by heterologous expression of the photopyrone synthase PpyS catalyzing the head-to-head condensation of two acyl moieties.

3-Benzyl-2H-chromen-2-one

Acta Crystallographica Section E, 2012
The title compound, C16H12O2, is a coumarin which was isolated from stones of the Chinese traditional medicine Clausena lansium. The pyrone ring is almost planar, with a mean deviation of 0.0135 (4) Å. The benzene ring (A) of

Coumarins Disrupt Cell–Cell Communication and Virulence in Priority Pathogens: Targeting the PQS Signalling System in Pseudomonas aeruginosa

Microbial Biotechnology, Volume 19, Issue 7, July 2026.
The selective nature through which coumarin compounds produced by different species of plants target PQS signalling in Pseudomonas aeruginosa and select for distinct phenotypic responses in key pathogenic organisms adds to the growing evidence of their utility as natural virulence suppressors. ABSTRACT Cell‐to‐cell communication in microbial systems is
