Enantioconvergent Access to Chiral S(VI) Stereocenters by Kinetic Resolution of Sulfonimidoyl Chlorides

Angewandte Chemie, EarlyView.
An enantioconvergent approach for the kinetic resolution of S(VI) stereocenters that leverages the electrophilic reactivity of the chiral sulfur atom is described. The catalytic process provides access to sulfonimidoyl chlorides and sulfonimidates, which are among the least studied S(VI) functionalities.

Zinc‐Coordinated Trienzyme Nanogel Cascade Therapy for Accelerated Post‐Pancreatectomy Cutaneous Wound Healing

Advanced Materials, EarlyView.
A zinc‐coordinated nanogel assembly is reported that co‐delivers three enzymes to regulate glucose, oxidative stress, and oxygen levels. This system mimics natural enzyme cascades to reprogram the wound environment after pancreatectomy. In a post‐pancreatectomy mouse model, it accelerates healing by reducing infection, promoting blood vessel growth ...

Biocatalytic Construction of a Chemical Exchange Saturation Transfer Magnetic Resonance Imaging Nucleoside Probe: Synthesis and Evaluation of 5‐Methyl‐5,6‐Dihydrothymidine

Advanced Synthesis &Catalysis, EarlyView.
Al‐Hilfi et al. present a biocatalytic strategy for synthesizing 5‐methyl‐5,6‐dihydrothymidine (5‐MDHT), a sensitive MRI contrast agent. The study demonstrates that recombinant enzyme catalysis offers an efficient, sustainable, and eco‐friendly alternative to traditional chemical synthesis for producing clinically relevant imaging probes.

Lipid peroxidation is a nonparenchymal cell event with reperfusion after prolonged liver ischemia [PDF]

, 1990
A proposed mechanism for irreversible ischemic liver damage has been peroxidation of membrane phospholipids by free radicals. However, the hepatocyte is laden with enzymes which are antioxidants and, therefore, ought to be relatively resistant to ...
