Provided are N-alkyl imidazole 2-aldoximes, including cationic imidazolium and uncharged tertiary imidazole aldoximes, and compositions and methods for making and using them, including methods for reactivating human butyrylcholinesterase (hBChE) or acetylcholinesterase (hAChE ) inhibited by organophosphate (OP). By administration of a composition of the invention, the inactive or conjugated hBChE-OP or hAChE-OP is reactivated and the catalytic cycle of turnover and inactivation of the OP is completed; and in alternative embodiments, secondary mechanisms of reversible protection of hBChE and hAChE from irreversible inactivation by OPs and reactivation of tissue AChE also contribute to overall efficacy.
提供了N-烷基
咪唑-2-醛
肟,包括阳离子
咪唑盐和不带电的三级
咪唑醛肟,以及制备和使用它们的组合物和方法,包括重新激活被有机
磷酸酯(OP)抑制的人丁酰
胆碱酯酶(hBChE)或
乙酰胆碱酯酶(hAChE)的方法。通过给予本发明的组合物,不活性或结合的hBChE-OP或hAChE-OP被重新激活,完成了OP的催化周转和失活循环;在替代实施方案中,可逆保护hBChE和hAChE免受OP不可逆失活的次要机制以及再激活组织AChE也有助于整体功效。
