Chemical Optimization of Temporin A–L Peptides: From Native Isoforms to Enhanced Antimicrobial Analogs

ChemMedChem, Volume 21, Issue 15, 14 August 2026.
Temporins, among antimicrobial peptides, are short frog‐derived molecules with potent antibacterial activity. This review highlights chemical optimization strategies applied to temporins A–L, showing how sequence tuning modulates structure, stability, and selectivity, enabling improved activity against resistant pathogens.

Visible‐Light Photoredox Catalysis in the Intramolecular Dicarbonylation of Alkenes: Catalyst‐Dependent Divergent Syntheses of Both 1,4‐Dicarbonyls and α‐Hydroxy‐β,γ‐Unsaturated Lactams From 1,2‐Dicarbonyls

Advanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
Catalyst‐dependent divergent syntheses were developed. Intramolecular dicarbonylation of vinyl halides under metal‐free either thermal or visible light photocatalytic conditions were explored to produce a series of 1,4‐dicarbonyls with two different carbonyl moieties and a lactam ring.

Chemoenzymatic Synthesis of Chiral Piperidines Using the Immobilized Transaminase ATA‐117 in Continuous Flow Reactors

Advanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
A robust continuous flow chemoenzymatic process was developed for the stereoselective synthesis of cis‐(2R,6R)‐2,6‐disubstituted piperidines, including the natural alkaloid (–)‐pinidinone. The asymmetric transamination of α,β‐unsaturated ketones was catalyzed by immobilized ATA‐117, followed by spontaneous aza‐Michael cyclization, providing the desired

The Development and Validation of a Simple Method for the Determination of Meropenem Concentrations in Human Plasma Using High‐Performance Liquid Chromatography

Applied Research, Volume 5, Issue 4, August 2026.
A simple, rapid, and sustainable HPLC‐UV method was developed and validated to quantify meropenem in human plasma across a wide linear range (0.5–100 mg/L). Utilizing an efficient one‐step protein precipitation, this eco‐friendly approach is highly suited for routine clinical therapeutic drug monitoring and research purposes.

Exploring the Roles of Tuna‐Associated Acinetobacter sp. YFT067: Implications for Host Health and Metabolism

Animal Research and One Health, Volume 4, Issue 3, Page 278-292, August 2026.
This study firstly isolated a tuna‐derived gut probiotic Acinetobacter seifertii YFT067. Dietary administration of YFT067 played significant roles in promoting growth performance, SCFAs production, lipid absorption, and metabolism of the host, indicating YFT067 as a promising probiotic candidate for enhancing tuna aquaculture productivity through ...
