Asymmetric autocatalysis with amplification of enantiomeric excess utilizing chiral crystals of achiral o-terphenyls as chiral triggers

Chiral crystals composed of achiral hydrocarbon o-terphenyl and its dimethoxy derivative, 4′,5′-dimethoxy-o-terphenyl have been successfully employed as chiral triggers in the enantioselective addition of diisopropylzinc to pyrimidine-5-carbaldehyde.

Plant NAOGAT (ArgJ) Structure Reveals Mechanism of Ornithine Biosynthesis, Preference for Acetylornithine and Susceptibility to Mangotoxin

Plant, Cell &Environment, EarlyView.
ABSTRACT Arginine metabolism in plants is targeted by phytopathogens such as Pseudomonas syringae strains, which produce toxins that affect enzymes of plant arginine metabolism, causing devastating infections in crops. In this work, the structural and functional properties of plant N‐acetylornithine glutamate acetyltransferase (NAOGAT), the key ...

Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

Integration of Chemical Probes and Degradomics Reveals That Cathepsin B Functions Primarily as a Dipeptidyl Carboxypeptidase in Macrophages

ChemMedChem, Volume 21, Issue 21, 12 November 2026.
An integrated chemical biology and degradomics approach reveals the proteolytic landscape of cathepsin B in mouse macrophages. Z‐RK‐AOMK perturbs the cysteine cathepsin network and reveals that cathepsin B predominantly exhibits dipeptidyl carboxypeptidase activity in cells.

Proto‐Panic Modulation by Caffeine‐Proteinoid Complexes

Journal of Applied Polymer Science, Volume 143, Issue 41, November 5, 2026.
Caffeine–proteinoid microspheres synthesized by thermal polymerization exhibit compartmentalized drug loading with encapsulation efficiencies of 61%–82% and triphasic release kinetics. Electrochemical monitoring reveals multi‐scale oscillatory dynamics consistent with chaotic and damped harmonic behavior, while Boolean logic operations demonstrate ...

Multienzyme Cascade Reactions: Compatibility, Cooperativity, and Control

Advanced Synthesis &Catalysis, Volume 368, Issue 21, 3 November 2026.
Multienzyme cascade reactions are sequences of telescoped biotransformations that avoid the isolation of intermediates and offer significant efficiency advantages over traditional multistep routes. This review article highlights recent examples of multienzyme cascades and explores how their success depends on the consideration of compatibility ...

Simple models of oscillating polymerizations:Dimeric form autocatalysis

, 2011
For two variable chemical oscillators, a simple strategy is to combine autocatalysis with a term including a binomial Michaelian denominator (constant+concentration). This strategy is applied in this paper to the context of polymerization reactions.
