corresponding in vitro evaluation for reactivation of paraoxon-inhibited electric eel acetylcholinesterase (EeAChE) and recombinant human acetylcholinesterase (rHuAChE) are reported. Several newly synthesized compounds efficiently reactivated inhibited EeAChE, but were poor reactivators of inhibited rHuAChE. Compounds bearing a thiophene ring in the side chain (20, 23, 26 and 29) showed better reactivation (24–37%
报道了一系列带有杂环侧链或功能化脂肪族侧链的单季吡啶肟的制备以及对对氧磷抑制电鳗乙酰胆碱酯酶 (EeAChE) 和重组人乙酰胆碱酯酶 (rHuAChE) 的再激活的相应体外评估。几种新合成的化合物有效地重新激活抑制 EeAChE,但它们是被抑制的 rHuAChE 的弱再激活剂。轴承在侧链(噻吩环的化合物20,23,26和29)显示出与用呋喃并异恶唑化合物杂环更好活化(24-37%为EeAChE和5-9%为rHuAChE)(为0-8% EeAChE 和 2–3% 的 rHuAChE) 在 10 -5 M. N-吡啶基-CH 2 COOH 类似物8在 10 -4 M 下重新激活了 EeAChE (36%) 和 rHuAChE (15%),对于 rHuAChE的k r值优于 2-吡啶醛肟 (2-PAM)。
