Anthraquinones From Epicoccum sp., a Fungus Isolated From Gut of Dione juno That Feeds on Passifloras

Chemistry &Biodiversity, Volume 23, Issue 6, June 2026.
An Epicoccum fungus was isolated from gut of larvae of the butterfly Dione juno juno that feeds intensively on leaves of Passifloras. This fungus produces hydroxyanthraquinones that moderately inhibits growth of some Bacillus that coexist with the fungus in the insect gut, suggesting that it is probably important for microbial embalance in gut flora ...

The Development and Characterization of a Panel of Amine Dehydrogenases (AmDHs) and Amino Acid Dehydrogenases (AADHs)

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
The CoE‐AmDH panel enables sustainable access to chiral amines using diverse amine (AmDH) and amino acid dehydrogenases (AADH). Utilizing formate (FDH) or glucose dehydrogenase (GDH) for cofactor regeneration, this study establishes a robust screening platform for mild reductive aminations.

Design of a Fluorescent Boronic Acid‐Functionalized Pyranoflavylium Receptor to Host and Release Diol‐Rich Bioactive Analytes in a pH‐Dependent Manner

ChemFoodChem, Volume 2, Issue 2, June 2026.
This work presents a pH‐responsive ON–OFF fluorescent system based on a novel pyranoflavylium dye functionalized with a boronic acid receptor. The receptor exhibits a markedly higher affinity for the catechol‐containing polyphenol (+)‐catechin than for conventional diol‐rich molecules such as glucose and lactic acid.

Effect of Reaction Time and Temperature on the Impurity Profile of Amphetamine in the Leuckart Method

Drug Testing and Analysis, Volume 18, Issue 6, Page 725-738, June 2026.
This study investigates the effect of the reaction temperature (step 1) and reaction time (step 1 and 2) on the conversion efficiency and impurity profile of amphetamine synthesized via the Leuckart method. Conversion efficiency and impurity profile were assessed using gas chromatography–flame ionization detection (GC–FID) and GC–mass spectrometry (GC ...

In Vivo and In Vitro Evaluation of PTeCA (1H‐Pyrrole‐2,3,4,5‐Tetracarboxylic Acid) in Hair Matrix as a Marker for Oxidative Cosmetic Treatment

Drug Testing and Analysis, Volume 18, Issue 6, Page 739-749, June 2026.
A total of 3378 self‐reported treated and untreated hair samples were analyzed for PTCA and PTeCA by LC‐MS/MS. Moreover, their in vitro formation was assessed in 225 untreated hair by different cosmetic treatments with and without oxidative agents. Data suggest that PTeCA could be a reliable marker for oxidative cosmetic treatments in hair.

Modulation of Ferroptosis Biomarkers by Thinned Apple Polyphenols Extract in Acute and Chronic Lung Injuries

eFood, Volume 7, Issue 3, June 2026.
Thinned apple polyphenols (TAP) extract reduced ferroptosis in acute and chronic lung injuries. TAP activated Nrf2 and modulated key biomarkers (MDA, NOX4, GPX4, FTH1), leading to decreased inflammation and fibrosis. These findings suggest TAP as a potential therapeutic approach for lung injury through ferroptosis regulation. ABSTRACT Acute and chronic
