Impurities such as O,S,S-trimethyl phosphorodithioate (TMPD) and the S-methyl isomer of malathion (isomalathion) strongly potentiated the mammalian toxicity of malathion. In contrast, impurities present in the phosphoramidothioate insecticide acephate had an antagonizing effect on its mammalian toxicity. The potentiation of

The reaction of bovine erythrocyte acetylcholinesterase (acetylcholine acetylhydrolase, EC 3.1.1.7) with a set of structurally related phosphorothiolates was studied in order to investigate the properties of the phosphorylated enzymes and to identify the leaving group. OOS- and OOS-trimethyl phosphorothiolates and

The biomolecular reaction constants (ki), dissociation constants (Kd), and phosphorylation constants (kp) were determined for the enantiomers of malaoxon against rat brain acetylcholinesterase, and for the stereoisomers of isomalathion against rat brain acetylcholinesterase and electric eel acetylcholinesterase. (R)-Malaoxon was an

Malathion [S-(1,2-dicarboethoxyethyl)O,O-dimethyl phosphorodithioate] is a commonly used organophosphorus insecticide reported to be genotoxic both in vivo and in vitro, but the reports are conflicting. In order to elucidate the genotoxic potency of the main compounds present in commercial preparations of

The cholinergic toxicity of malathion is exacerbated by its isomerization product, isomalathion, which inhibits detoxifying carboxylesterases as well as target acetylcholinesterase (AChE). Previous work has shown that the four stereoisomers of isomalathion, (1R, 3R), (1R, 3S), (1S, 3R), and (1S
