  动态组合化学中配体发现的多主题探针的候选者

  摘要：

  多功能化材料有望成为发现配体和目标生物材料之间特定相互作用的通用探针。因此，需要有效的方法来制备功能的可能组合。动态组合化学 (DCC) 的概念非常适合生成任何可能的组合，以及筛选目标生物材料。在这里，我们提出了一种新的多主题探针分子设计，用于 DCC 中的配体发现。我们合成了一种新的山墙卟啉 GP1，它具有 prop-2-yne 基团作为支架来引入各种功能基团。GP1 是通过 1,3-亚苯基部分连接的双（咪唑基卟啉锌）化合物，它通过强大的咪唑-锌互补配位自发和定量地产生大环。一些不同类型的官能团以高产率被引入 GP1。由具有不同类型取代基的 GP1 衍生物组成的异质大环的形成是在平衡条件下完成的。这些结果承诺，当 GP 组分的种类增加时，可以提供大量具有各种官能团的大环。这些特征是 DCC 所需要的，并且使用 GP1 的本系统是一个潜在的候选者，可提供多主题探针的动态组合库，以发现配体和

  We describe here the synthesis and activity of a new series of oxime reactivators of cholinesterases (ChEs) that contain tertiary amine or imidazole protonatable functional groups. Equilibration between the neutral and protonated species at physiological pH enables the reactivators to cross the blood-brain barrier and distribute in the CNS aqueous space as dictated by interstitial and cellular pH values. Our structure-activity analysis of 134 novel compounds considers primarily imidazole aldoximes and N-substituted 2-hydroxyiminoacetamides. Reactivation capacities of novel oximes are rank ordered by their relative reactivation rate constants at 0.67 mM compared with 2-pyridinealdoxime methiodide for reactivation of four organophosphate (sarin, cyclosarin, VX, and paraoxon) conjugates of human acetylcholinesterase (hAChE). Rank order of the rates differs for reactivation of human butyrylcholinesterase (hBChE) conjugates. The 10 best reactivating oximes, predominantly hydroxyimino acetamide derivatives (for hAChE) and imidazole-containing aldoximes (for hBChE) also exhibited reasonable activity in the reactivation of tabun conjugates. Reactivation kinetics of the lead hydroxyimino acetamide reactivator of hAChE, when analyzed in terms of apparent affinity (1/K-ox) and maximum reactivation rate (k(2)), is superior to the reference uncharged reactivators monoisonitrosoacetone and 2,3-butanedione monoxime and shows potential for further refinement. The disparate pH dependences for reactivation of ChE and the general base-catalyzed oximolysis of acetylthiocholine reveal that distinct reactivator ionization states are involved in the reactivation of ChE conjugates and in conferring nucleophilic reactivity of the oxime group.
