  由三唑-肟化合物库（乙酰胆碱酯酶的活化剂）逆转禁忌毒素的毒性

  摘要：

  乙酰胆碱酯酶（AChE）是一种降解神经递质乙酰胆碱的酶，当被有机磷化合物（OPs）（例如神经毒剂和杀虫剂）共价抑制时，可以被肟重新激活。然而，由于标准吡啶鎓醛肟肟解毒剂的低活化作用，塔邦仍然是最危险的神经制剂之一。因此，寻找最佳的活化剂来预防塔宾毒性和进行暴露后治疗仍然是一个挑战。在这项研究中，我们分析了炔烃和叠氮化物结构单元之间主要通过CuAAC三唑连接而合成的111种新型亲核肟的活化潜能。我们鉴定了几种肟，它们在禁忌暴露的人AChE中具有显着提高的体外再激活潜力，并且在禁忌暴露的小鼠中具有体内解毒作用。

  A series of structurally related monosubstituted 1-[(alkenyloxy)methyl]-, 1-[(alkynyloxy)methyl]-, and 1-[(aralkyloxy)methyl]-2-[(hydroxyimino)methyl]-3-methyli midazolium halides were prepared and evaluated. All new compounds were characterized with respect to (hydroxyimino)methyl acid dissociation constant, nucleophilicity, and octanol-buffer partition coefficient. The alkynyloxy-substituted compounds were also evaluated in vitro with respect to reversible inhibition of human erythrocyte (RBC) acetylcholinesterase (AChE) and kinetics of reactivation of human AChE inhibited by ethyl p-nitrophenyl methylphosphonate (EPMP). In vivo evaluation in mice revealed that coadministration of alkynyloxy-substituted imidazolium compounds with atropine sulfate provided significant protection against a 2 x LD50 challenge of GD. For the alkynyloxy-substituted imidazolium drugs there is a direct relationship between in vitro and in vivo activity: the most potent in vivo compounds against GD proved to be potent in vitro reactivators against EPMP-inhibited human AChE. These results differ from the observations made on the sterically hindered imidazolium compounds (see previous article) and suggest that several antidotal mechanisms of protective action may be applicable for the imidazolium aldoxime family of therapeutics. The ability of the alkynyloxy substituents to provide life-saving protection against GD intoxication was not transferable to the pyridinium or triazolium heteroaromatic ring systems.

  and for post‐exposure treatment is a continued challenge. In this study, we analyzed the reactivation potency of 111 novel nucleophilic oximes mostly synthesized using the CuAAC triazole ligation between alkyne and azide building blocks. We identified several oximes with significantly improved in vitro reactivating potential for tabun‐inhibited human AChE, and in vivo antidotal efficacies in tabun‐exposed
