Mechanically Assisted PO, PN, and PS Bonds Formation

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
We present a general mechanochemical strategy for constructing PO, PN, and PS bonds via solvent‐free reactions of phosphoryl chlorides with O‐, N‐, and S‐nucleophiles. The method operates under mild conditions, shows broad substrate scope, and affords phosphates, phosphoramidates, and thiophosphates efficiently, providing a sustainable platform for ...

Supercritical fluid extraction of organophosphorus pesticides from orange samples: Effect of solid additives on recovery [PDF]

, 1997
A method based on extraction with supercritical carbon dioxide has been developed for the analysis of pesticides in fruit. The method was tested on ten organophosphorus pesticides and dicloran in orange samples.

Efficacious Oxime for Organophosphorus Poisoning: A Minireview

, 2011
Oximes are well known as acetylcholinesterase reactivators and are used in organophosphorus poisoning to reactivate inhibited acetylcholinesterase. Therapeutically available oximes, namely, pralidoxime (2-PAM), obidoxime, trimedoxime and Hagedorn oxime ...

Neuroprotective Effects of N-Acetylcysteine-Amide (AD4) in a Survival Mouse Model of Paraoxon Intoxication: Targeting Oxidative Stress, Neuroinflammation and Memory Impairments

Antioxidants
Neurotoxicity induced by organophosphorus (OP) compounds such as paraoxon (POX) leads to severe brain damage and cognitive impairments. Although current treatments alleviate acute cholinergic symptoms, they fail to address secondary neurotoxicity.

Portable Thiocholine-Based Sensor for Monitoring Blood Cholinesterase Activity and Detecting Organophosphate and Carbamate Pesticides Using Personal Glucose Meters

Foods
The widespread use of organophosphate and carbamate pesticides in agriculture poses significant health risks due to their cholinesterase (ChE) inhibitory effects. However, existing detection methods are often expensive and require specialized facilities,
