  Quaternary salts of 2-[(hydroxyimino)methyl]imidazole. 2. Preparation and in vitro and in vivo evaluaton of 1-(alkoxymethyl)-2-[(hydroxyimino)methyl]-3-methylimidazolium halides for reactivation of organophosphorus-inhibited acetylcholinesterases

  摘要：

  A series of structurally related mono- and bis-1,3-disubstituted 2-[(hydroxyimino)methyl]imidazolium halides were evaluated in vitro for their ability to reactivate electric eel, bovine, and human erythrocyte (RBC) acetylcholinesterases (AChE) inhibited by ethyl p-nitrophenyl methylphosphonate (EPMP) and 3,3-dimethyl-2-butyl methyl-phosphonofluoridate (soman, GD). All new compounds were characterized for (hydroxyimino)methyl acid dissociation constant, nucleophilicity, octanol-buffer partition coefficient, reversible AChE inhibition, and kinetics of reactivation of EPMP-inhibited AChEs. For GD-inhibited AChEs, maximal reactivation was used to compare compounds since rapid phosphonyl enzyme dealkylation "aging" complicated interpretation of kinetic constants. For comparison, we also evaluated three known pyridinium therapeutics, 2-PAM, HI-6, and toxogonin. In vivo evaluation in mice revealed that when selected imidazolium compounds were coadministered with atropine sulfate, they were effective in providing lifesaving protection against both GD and EPMP challenges. This was a major accomplishment in the search for effective anticholinesterase therapeutics--the synthesis and preliminary evaluation of the first new monoquaternary soman antidotes with potencies superior to 2-PAM. Significantly, there was an apparent inverse relationship between in vitro and in vivo results; the most potent in vivo compounds proved to be the poorest in vitro reactivators. These results suggested that an alternative and possibly novel antidotal mechanism of protective action may be applicable for the imidazolium aldoximes. Selected compounds were also evaluated for their inhibition of AChE phosphorylation by GD and antimuscarinic and antinicotinic receptor blocking effects.

• The Generation of the Ethenethiolate Anion and Its Reaction with Several Chloromethyl Alkyl Ethers and Sulfides

  3-oxathiolane was deprotonated at the 4-position, followed by the cycloelimination of the resultant anion, leading to ethyl formate and the ethenethiolate anion. The anion was trapped by several chloromethyl alkyl ethers and sulfides to afford alkoxy(vinylthio)methanes and alkylthio(vinylthio)methanes respectively.

  2-Ethoxy-1,3-oxathiolane 在 4-位被去质子化，随后生成的阴离子环消，生成甲酸乙酯和乙烯硫醇阴离子。阴离子被几种氯甲基烷基醚和硫化物捕获，分别得到烷氧基（乙烯基硫代）甲烷和烷硫基（乙烯基硫代）甲烷。

  (Alkoxymethyl)dodecyldimethylammonium, (cycloalkoxymethyl)dodecyidimethylammonium, (alkylthiomethyl)dodecyldimethylammonium, (alkoxymethyl)dimethyloctylammonium, (cycloalkoxymethyl)dimethyloctylammonium and (alkylthiomethyl)dimethyloctylammonium chlorides were prepared in high yield. All the chlorides studied showed antimicrobial activity. The relationship between the chemical structure and antimicrobial activity was analyzed using the rough sets method.
