Insights on Regioselective Synthesis of Fused Thiazoles: Density Functional Theory Calculations, Local Reactivity Indices, and Molecular Electrostatic Potential Analysis

ChemistryOpen, EarlyView.
A regioselective synthesis of fused thiazoles was achieved via aza‐Michael cyclization of thiazolidinone derivatives with hydrazines or heteroaryl amines. Density functional theory, local reactivity indices, and molecular electrostatic potential mapping are used to explain selectivity.

Solvothermal Synthesis of Porous Aminated Poly(1,2,4‐Triazolium) Networks and Their Use in CO2 Capture and Conversion

Journal of Polymer Science, EarlyView.
Porous aminated poly(1,2,4‐triazolium) networks carrying varied counter anions were synthesized via solvothermal polymerization of a 1,2,4‐triazolium monomer with divinylbenzene as crosslinker. Their behaviors in CO2 capture and conversion were studied in detail.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Recent Synthetic Advances in C–H/N–H Functionalization of 1H‐Pyrazoles: Diverse Strategies Across Variously Substituted Scaffolds

The Chemical Record, EarlyView.
Systematic overview of pyrazole functionalization reactions from C‐5 to N−H. It covers different strategies, from traditional cross‐coupling of prefunctionalized pyrazoles to more efficient direct functionalizations. This review briefly and systematically overviews C–H and N–H functionalization reactions of pyrazoles, aimed at creating new CC and C ...

Structural insights for enhanced ROS detoxification of eKatE, a recently identified catalase in atypical E. coli

The FEBS Journal, EarlyView.
We revealed the crystal structure of eKatE from atypical E. coli. eKatE exhibits a hydrogen‐peroxide‐sensitive major channel, a stabilized dimeric interface, an unusual covalent bond between C392 and Y415, and other distinctive features. These structural features contribute to its enhanced catalase activity compared to KatE in typical E.

Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

The FEBS Journal, EarlyView.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit
