The kinetics of reactivation, by oximes, of cholinesterase inhibited by organophosphorus compounds.
The inhibition of cholinesterase (ChE) and related enzymes, by organophosphorus compounds, is generally believed to occur by direct phosphorylation of some group at the active centre of the enzyme, together with the liberation of an acid anion (Wilson, 1951; Balls & Jansen, 1952; Hartley & Kilby, 1952; Aldridge, 1954; Kilby & Youatt, 1954). Inhibition by organophosphorus compounds is generally ...
متن کاملThe reactivation of cholinesterase inhibited with organophosphorus compounds. 2. Reactivation by pyridinealdoxime methiodides.
Material8 The pyridinealdoxime methiodides were obtained by boiling the oximes with methyl iodide in ethanol (Green & Saville, 1956). Quinoline-4-aldoxime methiodide, m.p. 232-233° (Found: I 40x2. C11H11N20I requires 1 40.4%) and pyridine-2-alidoxime ethiodide, m.p. 186-188° (Found: I 45-3. C8H11N20I requires I 45-6%) were prepared similarly. Reactivation experiments These were carried out on h...

In this work, the effect of ligand's length on interaction energy of six oximes, A [2-(hydroxyimino)-N-((1-(2-(2-((hydroxyimino)methyl)-1H-imidazol-1-yl)ethyl)-1H-1,2,3-triazol-4-yl)methyl)acetamide], B [2-(hydroxyimino)-N-((1-(3-(2-((hydroxyimino)methyl)-1H-imidazol-1-yl)propyl)-1H-1,2,3-triazol-4-yl)methyl)acetamide], C [2-(hydroxyimino)-N-((1-(4-(2-((hydroxyimino)methyl)-1H-imidazol-1-yl)but...
متن کاملThe Thermochemistry of Some Organo- Phosphorus Compounds
After the combustions, the phosphoric acid was, in fact, in aqueous solution, so that a correction for the heat of solution was necessary. These combustions were made in a static bomb, and as a result the concentration of phosphoric acid probably varied considerably in different parts of the bomb, leading to the comparatively large error of ±O·l per cent, associated with the heats of combustion...
متن کاملCentral Cholinesterase Reactivation by Oximes Improves Survival and Terminates Seizures Following Nerve Agent Intoxication
The ability of oximes to reactivate organophosphorus nerve agent-inhibited acetylcholinesterase (AChE) activity is critical for protection against chemical warfare nerve agent intoxication. We have studied the capability of the tertiary oximes monoisonitrosoacetone (MINA) and diacetylmonoxime (DAM), in comparison with the quaternary oximes 2-PAM, HLo7 and MMB-4 to reactivate AChE inhibited by s...
