Organic synthesis using (diacetoxyiodo)benzene (DIB): Unexpected and novel oxidation of 3-oxo-butanamides to 2,2-dihalo-N-phenylacetamides

Beilstein Journal of Organic Chemistry, 2012
A novel and reliable method for the direct preparation of 2,2-dihalo-N-phenylacetamides is reported. The key transformation involves the cleavage of a carbon–carbon bond in the presence of DIB and a Lewis acid as the halogen source, and thus this method ...

Acute Modafinil Exposure Induces Neurobehavioral Alterations in Zebrafish: Implications for Off‐Label Cognitive Enhancement

Journal of Applied Toxicology, EarlyView.
ABSTRACT Modafinil (2‐(benzhydrylsulfinyl)acetamide) is a psychostimulant commonly prescribed for sleep disorders such as narcolepsy, excessive daytime sleepiness, and obstructive sleep apnea. Recently, its use has extended beyond clinical indications, with neurotypical individuals adopting it as a smart drug to enhance alertness and cognitive ...

Boronic Acid Inhibitors of β‐Lactamases: A Promising Strategy Against Antimicrobial Resistance

Medicinal Research Reviews, EarlyView.
ABSTRACT The rise of antimicrobial resistance (AMR) poses a critical threat to global health, mostly due to the proliferation of β‐lactamases, a class of enzymes responsible for the inactivation of β‐lactam antibiotics. Among the most promising strategies to restore β‐lactam efficacy is the use of β‐lactamase inhibitors (BLIs), with boronic acid ...

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Design, synthesis and activity evaluation of tetrahydroisoquinoline‐based programmed cell death ligand 1 inhibitors

Smart Molecules, EarlyView.
Based on a 3D‐quantitative structure‐activity relationship pharmacophore model, structural optimization of Y6 yielded Y7f. Mechanistic studies revealed that Y7f acted as a programmed death receptor 1/programmed cell death ligand 1 (PD‐L1) interaction inhibitor by inducing PD‐L1 dimerization. Y7f restored T‐cell function.
