In alternative embodiments, the invention provides nucleophilic hydroxyimino-acetamido alkylamine antidotes that cross the blood-brain barrier (BBB) to catalyze the hydrolysis of organophosphate (OP)-inhibited human acetylcholinesterase (hAChE) in the central nerve system (CNS). The hydroxyimino-acetamido alkylamines of the invention are designed to fit within AChE active center gorge dimensions, bind with reasonable affinity, and react with the conjugated phosphate atom in the gorge. The hydroxyimino-acetamido alkylamines of the invention are also designed to possess ionization states that govern affinity and reactivity for the two linked hAChE re-activation steps. In alternative embodiments, the invention provides pumps, devices, subcutaneous infusion devices, continuous subcutaneous infusion devices, infusion pens, needles, reservoirs, ampoules, a vial, a syringe, a cartridge, a disposable pen or jet injector, a prefilled pen or a syringe or a cartridge, a cartridge or a disposable pen or jet injector, a two chambered or multi-chambered pump, a syringe, a cartridge or a pen or a jet injector, comprising a compound of the invention.
在另一个实施方案中,本发明提供了亲核羟基亚氨基乙酰氨基烷基胺解毒剂,它可以穿过血脑屏障(BBB),催化中枢神经系统(CNS)中被有机磷(OP)抑制的人乙酰胆碱酯酶(hAChE)的水解。本发明的羟基亚氨基乙酰胺基烷基胺设计成适合 AChE 活性中心峡部尺寸,以合理的亲和力结合,并与峡部的共轭磷酸原子反应。本发明的羟基亚氨基乙酰氨基烷基胺还被设计成具有电离状态,这种电离状态可控制两个相连的 hAChE 再激活步骤的亲和性和反应性。在其他实施方案中,本发明提供了包含本发明化合物的泵、装置、皮下输液装置、连续皮下输液装置、输液笔、针头、贮液器、安瓿瓶、小瓶、注射器、针筒、一次性笔或喷射注射器、预填充笔或注射器或针筒、针筒或一次性笔或喷射注射器、双腔或多腔泵、注射器、针筒或笔或喷射注射器。
