corresponding in vitro evaluation for reactivation of paraoxon-inhibited electric eelacetylcholinesterase (EeAChE) and recombinant human acetylcholinesterase (rHuAChE) are reported. Several newly synthesized compounds efficiently reactivatedinhibited EeAChE, but were poor reactivators of inhibited rHuAChE. Compounds bearing a thiophene ring in the side chain (20, 23, 26 and 29) showed better reactivation (24–37%
A system includes at least one oxidase. at least one haloperoxidase; at least a first polymer including groups exhibiting nucleophilic activity for organophosphorus compounds, and a source of halide ions to serve as a substrate for haloperoxidase-catalyzed generation of halogens. The source of halide ions may, for example, include salt crystals or a salt in an extended release system. In a number of embodiments, the first polymer includes halide ions.
