Pyrazole‐Derived Antibacterial Compounds Effectively Treat Methicillin‐Resistant Staphylococcus Aureus Infections by Inhibiting Aspartate Transcarbamoylase

Advanced Science, EarlyView.
This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.

Chemoselective Difluoromethylation of Nucleosides

Organic Letters
A profiling platform to define the chemoselectivity of the carbene-mediated difluoromethylation of nucleosides is described. First, the optimized reaction conditions for the difluoromethylation of silyl-protected nucleosides are established using TMS-CF2Br and KOAc to form the difluoromethyl carbene in situ.

Glycosylation reactions mediated by hypervalent iodine: application to the synthesis of nucleosides and carbohydrates

Beilstein Journal of Organic Chemistry, 2018
To synthesize nucleoside and oligosaccharide derivatives, we often use a glycosylation reaction to form a glycoside bond. Coupling reactions between a nucleobase and a sugar donor in the former case, and the reaction between an acceptor and a sugar donor

Structural Probing and Molecular Modeling of the A3 Adenosine Receptor: A Focus on Agonist Binding

Molecules, 2017
Adenosine is an endogenous modulator exerting its functions through the activation of four adenosine receptor (AR) subtypes, termed A1, A2A, A2B and A3, which belong to the G protein-coupled receptor (GPCR) superfamily.

Discovery of an Antiviral Electron Transfer Process to Create Catalytically Self‐Sufficient Viral Restriction Factors

Angewandte Chemie International Edition, EarlyView.
CYB5R3 is identified as a putative electron‐transfer partner of viperin (RSAD2), explaining why ER localisation is required for antiviral activity. Its utilisation enabled the engineering of immune‐silent, catalytically self‐sufficient antiviral restriction factor enzymes (iCAREs) that produce an antiviral nucleoside triphosphate analogue (ANTA ...
