A Strong Lewis Acidic Diethylsilylium Catalyst for Direct Sulfonamidation of Challenging Ketones

Advanced Science, EarlyView.
Low‐substitution‐order silylium ions (R2HSi+) exhibit exceptional Lewis acidic activity. We report diethylsilylium‐catalyzed reductive sulfonamidation of functionalized ketones to access β‐amino esters. The in situ generated ion pair shows enhanced reactivity, with diethylsilane serving as both reductant and precatalyst. The developed protocol proceeds

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods

Chirality, Volume 38, Issue 7, July 2026.
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

Circadian Immunity and Vascular Inflammation in Cardiovascular Disease Chronotherapy Windows: Time for a Re‐Assessment

Med Research, Volume 2, Issue 2, Page 236-279, June 2026.
ABSTRACT Circadian rhythms orchestrate cardiovascular physiology by regulating immune and inflammatory pathways. Disruption of these rhythms profoundly alters vascular homeostasis, thereby promoting the onset and progression of cardiovascular diseases (CVD).

GLP‐1 agonists and the gut microbiome: A bidirectional relationship

British Journal of Clinical Pharmacology, Volume 92, Issue 5, Page 1309-1325, May 2026.
Abstract Glucagon‐like peptide‐1 (GLP‐1) receptor agonists have transformed the management of type 2 diabetes mellitus (T2DM) and obesity, yet their interactions with the gut microbiome remain an emerging frontier in pharmacological and metabolic research.

Eco‐Friendly and Economical Approach for Immobilization of Thermostable ω‐Transaminase

Chemistry–Methods, Volume 6, Issue 5, May 2026.
This work presents immobilization of thermostable ω‐Transaminase on diatomaceous earth using eco‐friendly Fe3+‐tannic acid complexes. The immobilized enzyme retains optimal activity and preserves over half its activity after repeated cycles, offering a simple, economical immobilization strategy for industrial biocatalysis.

Biocatalysis Under Reduced Pressure; Two‐Step, One‐Pot Amide Synthesis Using an Immobilised Transaminase/Lipase Cascade in Combination With By‐Product Removal

ChemBioChem, Volume 27, Issue 6, 27 March 2026.
The application of biocatalytic cascades for organic synthesis can be encouraged through the use of easy‐to‐handle, immobilised enzymes and common laboratory equipment. We present a sequential biocatalytic cascade reaction that couples a transaminase (ATA) with a lipase, and achieves high conversion and enantioselectivity through by‐product removal ...
