Esterase 2 as a Fluorescent Biosensor for the Detection of Organophosphorus Compounds: Docking and Electronic Insights from Molecular Dynamics [PDF]

open access: yes, 2019
Organophosphorus compounds (OP) are mainly used in agriculture as pesticides. Unfortunately, each year many rural workers die intoxicated by those compounds. Sometimes the diagnosis of the exact molecule that caused the intoxication can be tardy. In this

New Trends in Biosensors for Organophosphorus Pesticides

open access: yesSensors, 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 ...

A sweet emergency due to bitter poisoning—A case report

open access: yesJournal 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.

Substrate‐Controlled Enantiodivergence in Ni‐Catalyzed Access to Phosphorylated Oxindoles With Quaternary Stereocenters

open access: yesAngewandte 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
