Reactivation potency of the acetylcholinesterase reactivator obidoxime is limited.
BACKGROUND Obidoxime is the only one reactivator of acetylcholinesterase (AChE) approved in Czech Republic for the treatment of nerve agent and pesticide poisonings for civilian sector. Due to the fact that misuse of nerve agents by terrorists or by an accidental poisoning by farmers is possible, re-evaluation of its universality is needed. It is also needed by the fact that clinical findings c...
متن کاملPd(II) complexes of acetylcholinesterase reactivator obidoxime
The ability of the acetylcholinesterase reactivator obidoxime (H2L(2+)) to bind palladium(II) cations was evaluated spectrophotometrically at different reaction conditions (pH, reaction time, metal-to-ligand molar ratio). The results showed that immediately after mixing the reagents, pH 7.4, complex species of composition [PdHL](3+) existed predominantly with a value of conditional stability co...
متن کاملNew quaternary pyridine aldoximes as casual antidotes against nerve agents intoxications.
In this work, the ability of four newly synthesized oximes--K005 (1,3-bis(2-hydroxyiminomethylpyridinium) propane dibromide), K027 (1-(4-hydroxyiminomethylpyridinium)-3-(4-carbamoylpyridinium) propane dibromide), K033 (1,4-bis(2-hydroxyiminomethylpyridinium) butane dibromide) and K048 (1-(4-hydroxyiminomethylpyridinium)-4-(4-carbamoylpyridinium) butane dibromide) to reactivate acetylcholinester...
متن کاملSubstituted monoquaternary oximes as reactivators of cyclosarin--and chlorpyrifos--inhibited acetylcholinesterase.
This paper describes an in vitro study of three potential acetylcholinesterase (AChE; EC 3.1.1.7) reactivators derived from a monoquaternary reactivator pralidoxime. Compounds used were pyridinium-2-aldoxime-4-carbamoyl-N-methyl iodide (TO231), pyridinium-2-aldoxime-4-ethoxycarbonyl-N-methyl iodide (TO237), and pyridinium-2-aldoxime-5-ethoxycarbonyl-N-methyl iodide (TO238). Pralidoxime and obid...
متن کاملTwo step synthesis of a non-symmetric acetylcholinesterase reactivator.
The newly developed and very promising acetylcholinesterase reactivator (E)-1-(2-hydroxyiminomethylpyridinium)-4-(4-hydroxyiminomethylpyridinium)-but-2-ene dibromide was prepared using two different pathways via a two-step synthesis involving the appropriate (E)-1-(4-bromobut-2-enyl)-2- or 4-hydroxyiminomethyl-pyridinium bromides. Afterwards, purities and yields of the desired product prepared ...
