Sensing Organophosphorus Compounds with SWCNT Films [PDF]

Sensors, 2021
Promising electrical properties of single-walled carbon nanotubes (SWCNTs) open a spectrum of applications for this material. As the SWCNT electronic characteristics respond well to the presence of various analytes, this makes them highly sensitive ...

Prebiotic Chemistry of Phosphite: Mild Thermal Routes to Form Condensed-P Energy Currency Molecules Leading Up to the Formation of Organophosphorus Compounds [PDF]

Life, 2023
The in-fall of meteorites and interstellar dust particles during the Hadean–Archean heavy bombardment may have provided the early Earth with various reduced oxidation state phosphorus compounds and minerals, including phosphite (HPO32−)([Pi(III)]).

Interactions of cyclodextrins and their derivatives with toxic organophosphorus compounds [PDF]

Beilstein Journal of Organic Chemistry, 2016
The aim of this review is to provide an update on the current use of cyclodextrins against organophosphorus compound intoxications. Organophosphorus pesticides and nerve agents play a determinant role in the inhibition of cholinesterases.

Organophosphorus Compounds and MAPK Signaling Pathways. [PDF]

Int J Mol Sci, 2020
The molecular signaling pathways that lead to cell survival/death after exposure to organophosphate compounds (OPCs) are not yet fully understood. Mitogen-activated protein kinases (MAPKs) including the extracellular signal-regulated protein kinase (ERK), the c-Jun NH2-terminal kinase (JNK), and the p38-MAPK play the leading roles in the transmission ...

Chemical Weapons: History of the Study of Organophosphorus Toxic Agents Abroad

Вестник войск РХБ защиты, 2023
Organophosphorus compounds occupy a unique positon among all chemical warfare agents (CWA's). Since the 1930-s their high toxicity, wide range of physical-chemical properties and complex action attracted close attention of foreign military experts.

Chemistry, Metabolism and Neurotoxicity of Organophosphorus Insecticides: A Review [PDF]

Nature Environment and Pollution Technology, 2023
Organophosphorus compounds (OPs) are phosphoric acid derivatives represented by the formula (R2XP=O/S), R as organic groups; however, they need not contain a direct carbon-phosphorus bond.
