Thermal Catalytic Decomposition of Dimethyl Methyl Phosphonate Using CuO-CeO₂/γ-Al₂O₃

Applied Sciences, 2022
Chemical warfare agents (CWAs) are highly toxic and fast-acting and are easy to cause large-scale poisoning to humans and livestock after being released. The activated carbon used for CWAs adsorption has disadvantages of limited adsorption capacity, easy

Chemical terrorism and nerve agents

Medicine, 2007
Sarin and VX were released on an unprotected civilian population in Japan on six occasions in 1994−5. Clinicians must be prepared, therefore, to treat casualties from nerve agent exposure. This requires an understanding of the mechanisms of nerve agent toxicity and the factors which influence their clinical impact.

Targeted Synthesis of 1-(4-Hydroxyiminomethylpyridinium)-3-pyridiniumpropane Dibromide – A New Nerve Agent Reactivator

Molecules, 2007
Preparation of 1-(4-hydroxy-iminomethylpyridinium)-3-pyridiniumpropane dibromide is described. This compound represents a new acetylcholinesterase (AChE) reactivator, which has no substituents on the second pyridinium ring as found in other commonly used

Characterization of the Interaction of Nerve Agent Mimics with Selected Synthetic Receptors

Organic Materials, 2022
Qualitative NMR spectroscopic and quantitative calorimetric binding studies were performed to characterize the interaction of nontoxic mimics of the V-type nerve agent VX (O-ethyl S-[2-(diisopropylamino)ethyl] methylphosphonothioate) and the Novichok ...

Novel Bisquaternary Oximes—Reactivation of Acetylcholinesterase and Butyrylcholinesterase Inhibited by Paraoxon

Molecules, 2009
Four novel bisquaternary aldoxime cholinesterase reactivators differing in their chemical structure were prepared. Afterwards, their biological activity was evaluated for their ability to reactivate acetylcholinesterase (AChE; EC 3.1.1.7) and ...

The use of VX as a terrorist agent: action by Aum Shinrikyo of Japan and the death of Kim Jong-Nam in Malaysia: four case studies

Global Security: Health, Science and Policy, 2020
VX is a strong nerve-gas agent. In this paper, murder or injury of human made by VX is reported. First use of VX against human was made by Aum Shimrikyo in 1994 and 1995. More recently, VX was used in the assassination of Mr. Kim Jong-Nam in Kuala Lumpur,

Nerve agent hydrolysis activity designed into a human drug metabolism enzyme. [PDF]

PLoS ONE, 2011
Organophosphorus (OP) nerve agents are potent suicide inhibitors of the essential neurotransmitter-regulating enzyme acetylcholinesterase. Due to their acute toxicity, there is significant interest in developing effective countermeasures to OP poisoning.
