  一种高纯度(±)-反-4′-羧基可替宁的方法

  摘要：

  本发明公开了一种高纯度(±)‑反‑4'‑羧基可替宁的合成方法，其特征在于，将甲胺的乙醇溶液与3‑吡啶甲醛进行反应，控制温度25～30℃，反应熟成，然后减压浓缩溶剂，得到烯亚胺中间体Ⅰ；将烯亚胺中间体Ⅰ加入到二甲苯中，再加入丁二酸酐，再回流熟成；将反应液冷却至室温，然后减压浓缩去除二甲苯；浓缩结束后，将浓缩液的pH值调至8～9，再用二氯甲烷萃取有机杂质，分层后去除有机相，得到白色固体，抽滤后依次经水洗、冷乙醇淋洗，真空干燥得到目的物粗品，用乙醇进行重结晶，即得高纯度(±)‑反‑4'‑羧基可替宁。本发明制得的高纯度(±)‑反‑4'‑羧基可替宁HPLC纯度能达到99％以上，总收率60％以上。

  macrocyclic glycopeptide‐based chiral stationary phase (CSP), prepared via Edman degradation of vancomycin, was evaluated as a chiral selector for the first time. Its applicability was compared with other macrocyclic glycopeptide‐based CSPs: TeicoShell and VancoShell. In addition, another modified macrocyclic glycopeptide‐based CSP, NicoShell, was further examined. Initial evaluation was focused on the complementary

  通过对万古霉素的Edman降解制备的修饰的基于大环糖肽的手性固定相（CSP）被首次评估为手性选择剂。将其适用性与其他基于大环糖肽的CSP（TeicoShell和VancoShell）进行了比较。此外，还进一步检查了另一种基于大环糖肽的修饰CSP NicoShell。最初的评估集中在与这些糖肽的互补行为上。根据以前的工作，使用了一种筛选方法，用于对50种手性化合物的对映体分离，其中包括氨基酸，农药，兴奋剂和多种药物。使用表面多孔（核-壳）颗粒载体可实现快速有效的手性分离。总体，万古霉素埃德曼降解产物（EDP）与TeicoShell类似，在极性离子模式下对酸性化合物具有高对映选择性。使用液相色谱-质谱联用EDP同时分离5种外消旋脯氨酸的对映异构体，时间约为3分钟。其他亮点包括同时用VancoShell液相色谱分离rac-amphetamine和rac-methamphetamine，用Nico

  A parallel high throughput screening method on a solid support is disclosed that allows the detection of low affinity binding partners, comprising the steps of:(a) providing a library of different ligands;(b) forming a binding matrix comprising the ligands on a solid support by immobilising said ligands on the support; (c) contacting a target of interest with said binding matrix; (d) parallely determining a binding value of the ligand/target interaction for each type of ligand comprised in the binding matrix; (e) selecting those ligands the binding value of which in an immobilised state towards the target exceeds a predetermined threshold; (f) evaluating the affinity of each of the ligands selected in step (e) in a non-immobilised state towards the target; (g) identifying at least one ligand of step (f) as low affinity binding ligand.
