Identification of Natural Isonitriles Through Ligation to an Azomethine Imine Probe

open access: yesChemistry – A European Journal, EarlyView.
The azomethine imine (AMI)–isonitrile (NC) ligation allowed for the chemoselective detection of natural isonitriles in bacteria and fungi. The reactivity‐based screening establishes a new stereogenic center, thereby allowing for facile distinction between chiral and achiral isonitriles. The work also unraveled a unique reactivity of isonitriles bearing

Selective Modification of the Product Profile of Biocatalytic Hydrolyzed PET via Product‐Specific Medium Engineering

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The product profile of enzymatically hydrolyzed PET can be modified by medium engineering and thereby adapted to a desired product. TPA, MHET or BHET can be forced as the predominant product using a basic pH (blue), 25 % ethylene glycol (EG) and IsPETasewt (green) or ≥25 % EG and LCCICCG (pink), respectively.

Impacts of large herbivores on mycorrhizal fungal communities across the Arctic

open access: yesEcography, EarlyView.
Mycorrhizal fungi play an integral role in nutrient and carbon cycling in soils, which may be especially important in the Arctic, one of the world's most soil carbon‐rich regions. Large mammalian herbivores can influence these fungi through their impacts on vegetation and soil conditions, however the strength and prevalence of these interactions in the

Severity of effect considerations regarding the use of mutation as a toxicological endpoint for risk assessment: A report from the 8th International Workshop on Genotoxicity Testing (IWGT)

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.

Epigenotoxicity: Decoding the epigenetic imprints of genotoxic agents and their implications for regulatory genetic toxicology

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
Abstract Regulatory genetic toxicology focuses on DNA damage and subsequent gene mutations. However, genotoxic agents can also affect epigenetic marks, and incorporation of epigenetic data into the regulatory framework may thus enhance the accuracy of risk assessment.

Isorhamnetin Alleviates Renal Fibrosis Induced by Renal Tubular Epithelial Cell Senescence Via Inhibition of the IL‐6/IL‐6R Signaling Pathway

open access: yesiMetaMed, EarlyView.
IL‐6 from RTECs upregulates TGF‐β in macrophages, promoting fibroblast transdifferentiation. Isorhamnetin inhibits this effect. ABSTRACT Chronic kidney disease (CKD) is a major global health issue. Kidney fibrosis is a key mechanism leading to end‐stage renal disease.
