Urinary metabolites of sarin in a patient of the Matsumoto sarin incident
Archives of Toxicology, 1998Sarin metabolites were measured in urine from a patient with sarin poisoning. Two metabolites, methylphosphonic acid (MPA) and isopropylmethylphosphonic acid (iPMPA), were detected by gas chromatography after conversion to volatile derivatives with N-methyl-N-(tert-butyldimethylsilyl)-trifluoroacetamide in the urine from the victim collected on the ...

KINETICS OF THE ENZYMATIC HYDROLYSIS OF SARIN
Canadian Journal of Biochemistry and Physiology, 1956 The enzymatic hydrolysis of sarin is apparently a single first-order reaction. There is no evidence of different reaction rates for the two possible optical isomers of sarin. During both the enzymatic and the non-enzymatic hydrolyses, sarin appears to be detoxified somewhat more rapidly than the manometric results would indicate.

THE ENZYMATIC HYDROLYSIS PRODUCTS OF SARIN
Canadian Journal of Biochemistry and Physiology, 1956 The hydrolysis of the powerful cholinesterase inhibitor, sarin, by a rat serum enzyme leads almost exclusively to isopropyl methylphosphonic acid, neither methylphosphonic acid nor hydrogen methylphosphonofluoridate being formed. When isopropyl methylphosphonic acid is administered to the intact rat, it is excreted unchanged in the urine.

Biodegradation of neutralized Sarin
Biotechnology and Bioengineering, 1999This research investigated the biotransformation of IMPA, the neutralization product of the nerve agent Sarin, by a microbial consortia. As mandated by the Chemical Weapons Convention signed by 132 countries in 1993, all chemical warfare agents are to be destroyed within ten years of ratification.

Journal of Molecular Spectroscopy, 2001
As part of an effort to examine the possibility of using molecular-beam Fourier-transform microwave spectroscopy to unambiguously detect and monitor chemical warfare agents, we report the first observation and assignment of the rotational spectrum of the nerve agent Sarin (GB) (Methylphosphonofluoridic acid 1-methyl-ethyl ester, CAS #107-44-8) at ...

Sensors to Detect Sarin Simulant
Critical Reviews in Analytical Chemistry, 2020This work presents a literature review concerning the construction, properties and application of different sensors used to detect dimethyl methylphonate (DMMP), which is the simulant of sarin. Sensors sensitive to mass are described, together with such sensors as: SAW, QCM, MEMS, also chemical capacitors, semiconductors, and field effect transistors.

Refractoriness (Tachyphylaxis) to ‘Sarin’
Nature, 1962APART from experiments reported in 1954 by Barnes and Duff1, the occurrence of tachyphylaxis to poisons which act by inhibiting cholinesterase has been little publicized, although the phenomenon appears to offer possibilities as a means of investigating cholinergic function. The following is an account of a method which, in a proportion of experiments,

Given the current geopolitical tensions, the risk of a terrorist attack on the United States is constant and increasing. Chemical terrorism, specifically the use of nerve agents, has occurred in other nations. Because of the ease of manufacture, the ability to conceal them, and the lethality of these agents, they pose a potential threat as a weapon of ...
