Biosynthesis of Depsides, Depsidones, and Diphenyl Ethers from Fungi and Lichens
Asian Journal of Organic Chemistry, Volume 14, Issue 2, February 2025.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.

Methyltransferase Domain‐Focused Genome Mining for Fungal Polyketide Synthases
Small Methods, Volume 8, Issue 11, November 20, 2024.Genome mining is performed with a focus on the substrate‐binding amino acid residues in the C‐methyltransferase domains of fungal nonreducing polyketide synthases (NR‐PKSs). An NR‐PKS designated as AsbPKS is discovered and found to be responsible for the formation of anhydrosclerotinin B (1), the biosynthesis of which adopts a previously unreported ...

CNS Neuroscience &Therapeutics, Volume 30, Issue 11, November 2024.Because of CSF biomarkers identified by neuroimaging techniques in the middle or late stages of AD, blood is considered as the novel biomarker resource for the early diagnosis of AD. The accurate alternations in blood could predict AD. This paper discusses potential blood‐based biomarkers identified by proteomics and metabolomics and future research ...

Geministatins: new depside antibiotics from the fungus Austroacremonium gemini. [PDF]
J Antibiot (Tokyo)AbstractTwo new depside antibiotics, geministatins A (1) and B (2), were isolated from the fungus Austroacremonium gemini MST-FP2131 (Sordariomycetes, Ascomycota), which was recovered from rotting wood in the wet tropics of northern Australia. The structures of the geministatins were elucidated by detailed spectroscopic analysis, chemical degradation ...
