WebThe 3D structure of a potent phosphoramidothioate such as methamidophos was such that its P-O-group interacted with the enzyme's 'oxy-anion hole', NH 2 + group formed an H-bond with the enzyme's H-bonding site, and leaving group (-S) oriented toward the AChE 'gorge' opening. An alteration in its 3D structure also altered its toxicity. WebA process of making O,O-dimethyl phosphoroamidothioate is described including reacting sulfur with PCl 3 to form PSCl 3, reacting the PSCl 3 formed with methanol to form O-methyl phosphorodichloridothioate, and reacting the O-methyl phosphorodichloridothioate formed with methyl lye to form O,O-dimethyl phosphorochloridothioate in solution in CH 2 …

The first step in the mechanism is covalent addition of the OP to the side chain of lysine. This activates OP-lysine for reaction with a nearby glutamic or aspartic acid to make a gamma glutamyl epsilon lysine bond. …
