Acetylcholinesterase reactivators are crucial antidotes for the treatment of organophosphate intoxication. Eighteen monoquaternary reactivators of acetylcholinesterase with modified side chain were developed in an effort to extend the properties of pralidoxime. The known reactivators (pralidoxime, HI-6, obidoxime, trimedoxime, methoxime) and the prepared compounds were tested in vitro on a model of
乙酰胆碱酯酶激活剂是治疗有机磷酸中毒的关键解毒剂。开发了十八种带有修饰侧链的乙酰胆碱酯酶单季激活剂,以扩展普利昔肟的性质。在禁忌和对氧磷抑制的AChE模型上体外测试了已知的活化剂(普利昔肟,HI-6,obidoxime,三甲肟,甲氧肟)和制备的化合物。单季活化剂不能超过最知名的塔宾中毒化合物,但是其中一些确实表现出更好的活化性,或与对氧磷中毒的普利多肟具有可比性。但是,通过SAR研究发现,活化剂分子非肟部分的各种侧链存在很大差异。
