We report the synthesis of new polymers based on a dimethylacrylamide-methacrylate (DMAA-MA) co-polymer backbone that support both chemical and biological agent decontamination. Polyurethanes containing the redox enzymes glucose oxidase and horseradish peroxidase can convert halide ions into active halogens and

The reactions of pea diamine oxidase (PSAO) and 2-phenylethylamine oxidase from Arthrobacter globiformis (AGAO) with pyridine-derived oximes were studied. Pyridine carbaldoximes and alkyl pyridyl ketoximes act as strong non-competitive inhibitors of the enzymes. The inhibition constants K(i) of these compounds

O-Substituted aldoximes of the cholinesterase reactivator pralidoxime (O-methyl 1, O-benzyl 2, O-propynyl 3 and O-butynyl 4 derivatives) were synthesized and found to exhibit strong binding affinities for muscarinic receptors in rat brain, heart and submandibulary glands. The aldoximes were noncompetitive
