  New System for Peptide Synthesis Using N-Acylpyrazoles

  摘要：

  New system of peptide synthesis was described. The extension of one amino acid unit on the peptide chain was constituted from only 2 reaction steps, the conversion from esters to the corresponding N-acylpyrazoles and the subsequent aminolysis with amino esters. This new system was distinctive from the conventional peptide synthesis, which was consisted of 3 steps of the deprotection, the activation and the condensation. Moreover, the key intermediate N-acylpyrazoles exhibited the excellent properties of high sensitivity and separability for the chiral column on HPLC using the UV detector.

  Synthesis of novel orthogonally protected 1,3,4-thiadiazole and 1,3,4-oxadiazole tethered dipeptide mimetics is described. Both the heterocycles are prepared via a set of diacylhydrazines derived from amino acids. 1,3,4-Thiadiazoles are synthesized by dehydrosulfurization using Lawesson’s reagent while 1,3,4-oxadiazoles are obtained by EDC mediated cyclodehydration.

  Recently, we identified a novel class of potent cathepsin L inhibitors, characterized by a thiocarbazate warhead. Given the potential of these compounds to inhibit other cysteine proteases, we designed and synthesized a library of thiocarbazates containing diversity elements at three positions. Biological characterization of this library for activity against a panel of proteases indicated a significant preference for members of the papain family of cysteine proteases over serine, metallo-, and certain classes of cysteine proteases, such as caspases. Several potent inhibitors of cathepsin L and S were identified. The SAR data were employed in docking studies in an effort to understand the structural elements required for cathepsin S inhibition. This study provides the basis for the design of highly potent and selective inhibitors of the papain family of cysteine proteases.

  最近，我们鉴定出一类新型高效组织蛋白酶L抑制剂，其特点是具有硫卡巴脒头部结构。鉴于这些化合物有可能抑制其他半胱氨酸蛋白酶，我们设计并合成了一系列硫卡巴脒类化合物，这些化合物在三个位点上含有多样性元素。该化合物的生物活性鉴定结果显示，它们对木瓜蛋白酶家族的半胱氨酸蛋白酶相较于丝氨酸、金属蛋白酶以及某些类别的半胱氨酸蛋白酶（如胱天蛋白酶）表现出显著的选择性。我们鉴定出了几个高效的组织蛋白酶L和S抑制剂。通过对接研究，我们利用SAR数据来理解实现组织蛋白酶S抑制所需的结构要素。这项研究为设计高度有效且选择性的木瓜蛋白酶家族半胱氨酸蛋白酶抑制剂奠定了基础。

• N-benzhydryl-glycolamide esters (OBg esters) as carboxyl protecting groups in pept1de synthesis
  作者：Muriel Amblard、Marc Rodriguez、Jean Martinez

  日期：1988.1

  N-Benzhydryl-glycolamide esters (OBg esters) of various N-protected amino acids have been synthesized. In order to demonstrate their usefulness in peptide chemistry, the syntheses of For-Met-Leu-Phe-OH (chemiotactic peptide) and Pro-Leu-Gly-NH2 (MIF) have been carried out. OBg esters are compatible with commonly used protecting groups and are cleanly and selectively removed in mild alkaline conditions

  已经合成了各种N-保护的氨基酸的N-苯甲酰基-乙醇酰胺酯（OBg酯）。为了证明它们在肽化学中的有用性，已经进行了For-Met-Leu-Phe-OH（趋化肽）和Pro-Leu-Gly-NH 2（MIF）的合成。OBg酯与常用的保护基团相容，并且除含有β-苄基天冬氨酰的序列外，在温和的碱性条件下可以干净而有选择地除去，而没有任何副反应。
