  制备了含有胆囊收缩素 C 端小片段的 N-酰基-γ-D-谷氨酰肽衍生物，并研究了它们对胃液分泌的影响。PhCO-D-Glu(Phe-NH2)-NPr2和PhCO-D-Glu(Asp-Phe-NH2)-NPr2抑制胃液分泌，而PhCO-D-Glu(Met-Asp-Phe-NH2)-NPr2和PhCO-D-Glu(Trp-Met-Asp-Phe-NH2)-NPr2刺激胃液分泌。PhCO-D-Glu(Phe-NH2)-NPr2 N 端酰基功能的替代影响了其活性。研究发现，Z-D-Glu(Phe-NH2)-NPr2、4-氯苯甲酰基-D-Glu-(Phe-NH2)-NPr2 和异烟酰基-D-Glu(Phe-NH2)-NPr2 对胃液分泌的抑制活性比丙谷胺（PhCO-DL-Glu-NPr2）更强。

  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
• Application of Cyclam-Capped β-Cyclodextrin-Bonded Silica Particles as a Chiral Stationary Phase in Capillary Electrochromatography for Enantiomeric Separations
  作者：Yinhan Gong、Hian Kee Lee

  日期：2003.3.1

  Two novel types of substituted cyclam-capped β-cyclodextrin (β-CD)-bonded silica particles have been prepared and used as chiral stationary phases in capillary electrochromatography (CEC). The two stationary phases have a chiral selector with three recognition sites:  β-CD, cyclam, and the latter's sidearm. They exhibit excellent enantioselectivities in CEC for a wide range of compounds as a result of the cooperative functioning of the anchored β-CD and cyclam. After inclusion of the metal ion (Ni2+) from the running buffer into the substituted cyclams and their sidearm ligands, the bonded stationary phases become positively charged and can provide extra electrostatic interactions with ionizable solutes and enhance the dipolar interactions with some polar neutral solutes. This enhances the host−guest interaction with some solutes and improves chiral recognition and enantioselectivity. These new types of stationary phases exhibit great potential for fast chiral separations in CEC.

  两种新型取代的环烷基顶端β-环糊精（β-CD）键合二氧化硅颗粒已被制备并用于毛细管电色谱（CEC）中的手性固定相。这两种固定相具有一个包含三个识别位点的手性选择剂：β-CD、环烷基和环烷基的侧链。它们在CEC中对广泛化合物表现出优异的对映选择性，原因在于锚定的β-CD和环烷基的协同作用。在运行缓冲液中金属离子（Ni2+）被包含到取代的环烷基及其侧链配体后，键合的固定相变为正电荷，从而能够与可电离溶质提供额外的静电相互作用，并增强与一些极性中性溶质的偶极相互作用。这增强了与某些溶质的宿主-客体相互作用，提高了手性识别和对映选择性。这些新型固定相在CEC中展现出快速手性分离的巨大潜力。

  Proglumide is used in the treatment of neuropathic pain. It acts by inhibiting peptide cholecystokinin (CCK). Neural injury produces an elevation in plasma CCK. Proglumide has been also shown to augment the analgesic effect of sustained release morphine in neuropathic pain. Currently proglumide is administered as a racemic mixture. In the present study, an attempt is made to separate the racemic Mixture of the drug using lipase obtained from Candida cylindracea by stereoselective esterification. Enzymatic stereoselective esterification was carried out in organic solvents. The resolution was studied using a chromatographic column with a chiral support and mass spectrometry. The reaction conditions for stereoselective esterification including amount of substrate, amount of enzyme. alcohol, solvent and temperature were optimised during the present investigation. Butanol and hexanol were found to be suitable for formation of S and R esters. respectively. Hexane was the best solvent for esterification and the optimum temperature was found to be 30 degreesC.
