  摘要：

  合成了30个波杀菌蛋白类似物，并测定了它们对脯氨酰内肽酶、人白细胞弹性蛋白酶和组织蛋白酶B的抑制活性。对内肽酶抑制活性来说，α–酮基非常重要，β–取代–β–氨基–α–氧代丙酸部分的S构型比R构型更为优越。用L–亮氨酸代替波杀菌蛋白中的D–亮氨酸得到的类似物对组织蛋白酶B具有很强的抑制活性。将芳香基团引入到P4位和将脯氨酸引入到P2位使对弹性蛋白酶的抑制活性增强。苄氧羰基–L–高苯丙氨酰–(RS)–3–氨基–2–氧代戊二酰–D–亮氨酰–L–缬氨酸对脯氨酰内肽酶的活性约为天然波杀菌蛋白的6倍。

  The reactions of N-acyl-N-benzyl-α-amino acids (1) or N-acylprolines (5) with trifluoroacetic anhydride in the presence of pyridine afford 5-trifluoromethyloxazoles (2 or 7) in good yields. The reaction could proceed through the transient formation of mesoionic 1, 3-oxazolium-5-olates, followed by oxazolium salts.

  A process for esterifying organic carboxylic acids which comprises reacting an organic carboxylic acid with a carbonic acid ester of the formula: ##EQU1## wherein R is an organic group and X and Y are each a negative group in the presence of a basic substance to make esterified the carboxyl group in the organic carboxylic acid. The process is advantageous in affording the objective carboxylic ester in a good yield within a short time by a simple operation under a mild reaction condition.

  Chemoenzymatic peptide synthesis is potentially the most cost-efficient technology for the synthesis of short and medium-sized peptides with some important advantages. For instance, stoichiometric amounts of expensive coupling reagents are not required and racemisation does not occur, thus rendering purification easier compared to chemical peptide synthesis. The economically most attractive synthesis runs in the

  化学酶促肽合成可能是合成短和中等大小肽的最经济有效的技术，具有一些重要的优势。例如，不需要化学计量的昂贵偶联剂，也不会发生外消旋化，因此与化学肽合成相比，纯化更加容易。经济上最具吸引力的合成是在NC末端方向进行的，其中廉价的C末端保护的氨基酸被用作延伸的基础。然而，延长步骤后的C末端脱保护和激活-不会裂解侧链保护基或肽键-仍然是一个挑战。在本文中，我们描述了一种新颖的C丝氨酸内肽酶Alcalase催化末端酯的相互转化。C-末端保护的肽叔丁酯以定量收率被酶促转化为伯烷基酯，并与另一种氨基酸叔丁酯直接用于下一步的酶促延伸步骤。通过C-末端酯互变的这种完全酶促NC延伸策略被用于合成高达五聚体水平的生物活性肽。
