New Enzymatic Targets for Organophosphorus Compounds
Вестник войск РХБ защиты, 2023 It is known that several decarboxylases (aromatic amino acid decarboxylase (AAD), histidine decarboxylase (HD) and glutamate decarboxylase (GD) with different molecular weights catalyze the most important reactions of neurotransmitter and neuromodulator ...

New Trends in Biosensors for Organophosphorus Pesticides
Sensors, 2001 Biosensors are sensitive and can be used as disposable sensors for environmental control. These biosensors are based either on inhibition of acyl cholinesterases acetylcholinesterase or butyrylcholinesterase) by organophosphorus compounds or on ...

Zero-field NMR J-Spectroscopy of Organophosphorus Compounds
, 2020 In this paper, we report the results of theoretical and experimental studies on basic organophosphorus compounds using zero-field NMR, where spin dynamics are investigated in the absence of a magnetic field with the dominant heteronuclear J-coupling. We

A sweet emergency due to bitter poisoning—A case report
Journal of Family Medicine and Primary Care, 2023 Organophosphorus compounds (OPC) are major components of pesticides and nerve gas agents. Self-harm by ingestion of OPC pesticides is one of the common problems encountered in the emergency room (ER), especially in developing countries such as India.

Angewandte Chemie, EarlyView.An efficient, enantiodivergent synthesis of phosphorylated oxindoles with quaternary stereocenters is achieved via a nickel‐catalyzed intermolecular Heck‐phosphorylation cascade. Employing a single chiral catalyst, either product enantiomer is selectively accessed simply by changing the alkene leaving group. DFT calculations trace this stereodivergence

Angewandte Chemie, EarlyView.Photochemically generated phosphoryl radicals from iminyl phosphines enable strain‐release addition to azabicyclobutanes, providing access to elusive N‐phosphoryl azetidines. Combined experimental, computational, and EPR studies reveal an unconventional water‐assisted photoredox pathway.
