  摘要：

  我们描述了一种实用和通用的协议，用于使用界面 Lifshitz-van der Waals 相互作用将多相催化剂固定到机械坚固的多孔超高分子量聚乙烯片上。多种类型的粉状催化剂，包括Cu、Pd/C、Pd/Al 2 O 3、Pt/C和Rh/C已被成功固定。固定化催化剂对于在溶液中搅拌具有良好的机械稳定性，并且它们在各种合成反应中表现良好。固定化催化剂片易于处理和重复使用。此外，固定化催化剂的金属浸出显着减少。

  摘要：

  对新型肽类抗生素的探索将这项研究导向设计和合成具有修饰的两亲性组氨酸和疏水色氨酸残基的短序列。二肽 Trp-His(1-Bn)-OMe/NHBn 和三肽 His(1-Bn)-Trp-His(1-Bn)-OMe/NHBn 的新结构类别显示出有前景的抗真菌和抗菌活性和膜溶解作用。二肽 Trp-His[1-(3,5-二叔丁基苄基)]-NHBn ( 13d ) 显示了理想的亲水-亲油平衡，它产生了最有希望的抗真菌活性，IC 50值为 2.10 μg/ mL 和 MIC = 3.81 μg/mL，对C. neoformans和对E. faecalis的抗菌活性和金黄色葡萄球菌具有相同的 IC 50值为 4.40 μg/mL 和 8.0 μg/mL 的 MIC。肽13d在MIC值及以上没有表现出细胞毒性和溶血作用。这种典型的两亲性进一步得到了机理解释的证实，这表明肽通过利用电荷和疏水性作为主要特征工具

• A Simple Microscale Method for Determining the Relative Stereochemistry of Statine Units
  作者：Alejandro Preciado、Philip G. Williams

  DOI：10.1021/jo8012429

  日期：2008.12.5

  A simple method to determine the relative stereochemistry of statine amino acids (gamma-amino-beta-hydroxyacids) by using (1)H NMR spectroscopy is described. Configurational assignment of statine units within complex natural products is possible without degradation or derivatization as the syn and anti diastereomers can be distinguished by using a combination of chemical shift and coupling constant

  描述了一种通过使用（1）H NMR光谱确定他汀类氨基酸（γ-氨基-β-羟基酸）的相对立体化学的简单方法。在复杂的天然产物中，他汀类单元的构型分配是可能的，而不会降解或衍生化，因为可以通过结合使用化学位移和衍生自α-亚甲基ABX系统的耦合常数信息来区分顺式和反非对映异构体。提供了七个示例，说明了该方法的范围和局限性。这些示例的复杂性范围很广，从简单的他汀类药物单元到环状二肽肽，如坦丹林B。

  agonist peptides is an essential stereo-electronic feature for Angiotensin II to exert its biological activity. A non-peptide mimetic of ANG II, 1-[2'-[(N-benzyl)tetrazol-5-yl]biphenyl-4-yl]methyl]-2-hydroxymethylbenzimidazole (BZI8) has been designed and synthesized. This molecule is more rigid and much less active than AT(1) non-peptide mimetic losartan probably because it lacks to mimic the orientation

  A method is described for the synthesis of Nα-protected bi- and trifunctional amino acid p-nitroanilides. The reaction uses phosphorus oxychloride as the condensing agent. The synthesis is simple, rapid, free of racemization and affords yields between 70–90%. The synthesis can be performed not only with amino acid derivatives of the urethane type including acid-labile (Z. Boc) and base-labile (Fmoc
