  筛选 DFP 和对氧磷抑制乙酰胆碱酯酶的有效水杨醛肟再激活剂

  摘要：

  之前我们报道了两种水杨醛肟缀合物（L7R3和L7R5），与奥比肟和HI-6相比，对有机磷神经毒剂和农药抑制的乙酰胆碱酯酶表现出相同甚至更高的再激活效率。在这项研究中，选择L7R3和L7R5作为先导化合物，并采用基于片段的药物设计策略进行精制，总共构建了32种新型水杨醛肟缀合物，并筛选了DFP和对氧磷抑制乙酰胆碱酯酶的活性。研究结果表明，与奥比肟和 HI-6 相比，含有 4-硝基苯基的缀合物 L73R3 对对氧磷抑制的乙酰胆碱酯酶表现出更高的再激活功效。已证实4-吡啶基或4-硝基苯基外围位点配体、哌嗪连接体和甲基或氯取代的水杨醛肟的组合可以构建有效的非季铵肟再活化剂。研究结果有望开发出新一代高效有机磷中毒解毒剂。

  for reactivation of both nerve agents and pesticides inhibited hAChE were described in this paper. It was found that substituted salicylaldehydes conjugated to aminobenzamide through piperidine would produce efficient reactivators for sarin, VX and tabun inhibited hAChE, such as L6M1R3, L6M1R5 to L6M1R7, L4M1R3 and L4M1R5 to L4M1R7. The in vitro reactivation experiment for pesticides inhibited hAChE

  本文描述了一系列新的非季铵盐共轭物，用于神经活性剂和农药抑制hAChE的活化。发现通过哌啶与氨基苯甲酰胺缀合的取代的水杨醛将产生沙林，VX和塔宾抑制的hAChE的有效活化剂，例如L6M1R3，L6M1R5至L6M1R7，L4M1R3和L4M1R5至L4M1R7。在体外首次进行了农药抑制hAChE的复活实验。尽管它们的效率不如奥比多肟，但与2-PAM相比，它们中的一些被认为是同等或更有效的再活化剂。发现在大多数情况下，引入外围位点配体可以增加肟对抑制的hAChE的结合亲和力，从而导致更大的再活化能力。

  The one-pot bromo- and chloro-methylation of various 5-substituted salicylaldehydes with paraformaldehyde and hydrobromic or hydrochloric acid has been achieved. This approach establishes a convenient and flexible method to attach functional arms to salicylaidehydes for further applications in organic and coordination chemistry. Examples are described using 3-bromomethyl-5-t-butylsalicylaldehyde in the synthesis of piperazine-containing heteroditopic ligands as receptors for metal salts. (c) 2006 Elsevier Ltd.

• Conjugates of salicylaldoximes and peripheral site ligands: Novel efficient nonquaternary reactivators for nerve agent-inhibited acetylcholinesterase

  A new family of nonquaternary reactivators for nerve agent-inhibited human acetylcholinesterase (hAChE) were designed, synthesized and tested in this paper. It was found that salicylaldoximes were able to quickly cleave the P-S bond of organophosphate and avoid the reinhibition phenomenon in the reactivation process, but they lacked reactivating ability due to poor affinity for AChE. Based on a dual site binding strategy, different peripheral site ligands of AChE were introduced to achieve extra affinity. The in vitro reactivation experiments demonstrated that some of the yielding conjugates exhibited similar or even superior ability to reactivate sarin-, VX- or tabun-inhibited hAChE in comparison with the mono-and bis-pyridinium aldoximes currently used. Moreover, due to greatly improved lipophilicity, these nonquaternary conjugates hold promise for the development of efficient centrally activating reactivators. (C) 2017 Elsevier Ltd.
