Quaternary anticholinesterase therapeutics. Annual report, 22 July 1986-21 July 1987
Ninety-five new imidazolium, pyridinium, and 1,2,4-triazolium salts were prepared, characterized, and submitted to WRAIR for in-vivo evaluation as antidotes against the nerve agent soman. Many of the salts were evaluated at the U.S. Army Institute of Chemical Defense (ICD) in the mouse as treatment therapeutics for organophosphonate nerve agent intoxication. Of the effective type I compounds, those that provided the greatest protective ability incorporated side chains functionalized with nitro, sulfone, and amino groups. In an effort to prepare type I and II compounds that have the potential to reactivate aged, inhibited acetylcholinesterase by means of a chelated metal ion, several new phosphatase simulant ligands were prepared and characterized. Unfortunately, the ligands could not be induced to form stable metal complexes. Finally, a methodology for preparing 4(5)-substituted imidazoles was established and subsequently applied to the preparation of several new 4(5)-substituted type I salts.
