NCN Pincer‐Type Complexes of Group X Metals Bearing 1,3‐Di(5‐butylpyrazol‐3‐yl)benzene Ligands

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Electrophilic aromatic substitution and oxidative addition are two mechanisms that pave the way to novel 1,3‐dipyrazolylbenzene containing Group X metal NCN pincer‐type complexes. The oxygen and moisture stable compounds show interesting photophysical properties including fluorescence, which have been elucidated using a combination of spectroscopy and ...

Yellow canopy syndrome of sugarcane: A review of current knowledge and future research directions

Annals of Applied Biology, EarlyView.
Yellow Canopy Syndrome (YCS) is a complex issue affecting commercial sugarcane in Australia, first identified in Far North Queensland over a decade ago. It has spread across most cane‐growing regions in Queensland and poses a significant threat to the global sugarcane industry.

Targeting G9a decreases escalated alcohol drinking in male mice in a model of combined stress and chronic alcohol exposure

Alcohol, Clinical and Experimental Research, EarlyView.
Targeting dependence‐ and/or stress‐escalated alcohol drinking could help patients with alcohol use disorder (AUD). We found that reducing the activity of the epigenetic regulatory enzyme G9a (aka euchromatic histone‐lysine N‐methyltransferase 2 or EHMT2) either by a viral knockdown in the nucleus accumbens (NAc) or by repeated systemic administration ...

Plasma apolipoproteins and memory function in alcohol use disorder: Findings in male C57BL/6J mice and men suggest a role for APOAI

Alcohol, Clinical and Experimental Research, EarlyView.
Both alcohol‐dependent mice and abstinent AUD patients exhibited elevated plasma APOAI levels and memory impairments compared to controls. Higher APOAI levels were associated with poorer memory in both species, suggesting its potential as a biomarker for alcohol‐related cognitive deficits.

Biocatalytic Alkylation of Ambident Nucleophiles Enables Selective N‐Functionalization of Heterocycles and Late‐Stage Modifications

Angewandte Chemie, Volume 137, Issue 36, September 1, 2025.
N‐alkylated heteroarenes are key structural motifs in bioactive compounds, but their regioselective synthesis via coupling of readily available azoles with haloalkanes remains very challenging. Here, we present a mild biocatalytic approach that proceeds on gram‐scale, is highly chemo‐ and regioselective, offering rapid access to valuable N‐alkylated ...
