  H-Ser-Pro-Val-Thr-Leu-Asp-Leu-Arg-Tyr-OMe, corresponding to the sequence 41-49 of eglin c, inhibited human leukocyte cathepsin G and α-chymotrypsin. In order to gain further insight into the relationship between the structure and the inhibitory activity against cathepsin G and α-chymotrypsin, peptide fragments related to the above nonapeptide were synthesized by a conventional solution method and their inhibitory activities were examined. The smallest peptide which exhibited inhibitory effects on the above envymes was H-Pro-Val-Thr-Leu-OMe, corresponding to the sequence 42-45 of eglin c.

  H-Ser-Pro-Val-Thr-Leu-Asp-Leu-Arg-Tyr-OMe，对应于eglin c的第41-49位序列，对人类白细胞组织蛋白酶G和α-胰凝乳蛋白酶具有抑制作用。为了更深入地了解其结构与对组织蛋白酶G和α-胰凝乳蛋白酶抑制活性之间的关系，通过常规液相方法合成了与上述九肽相关的片段，并检测了它们的抑制活性。对上述酶表现出抑制作用的最小肽是H-Pro-Val-Thr-Leu-OMe，对应于eglin c的第42-45位序列。

  Various peptide fragments related to eglin c, which consists of 70 amino acid residues, were synthesized by a conventional solution method and their inhibitory effects on leukocyte elastase, cathepsin G and α-chymotrypsin were examined. Among them, H-Arg-Glu-Tyr-Phe-OMe (eglin c 22-25) and H-Ser-Pro-Val-Thr-Leu-Asp-Leu-Arg-Tyr-OMe (eglin c 41-49) inhibited cathepsin G and α-chymotrypsin but not leukocyte elastase, while H-Thr-Asn-Val-Val-OMe (eglin c 60-63) inhibited leukocyte elastase but not cathepsin G or α-chymotrypsin, although eglin c potently inhibited leukocyte elastase, cathepsin G and α-chymotrypsin. These results indicated that the interaction sites of eglin c with leukocyte elastase, cathepsin G and α-chymotrypsin might be different.

  采用常规的溶液法合成了与来自家蚕血淋巴的抗蛋白酶eglin c（由70个氨基酸残基构成）相关的各种肽片段，并检验了它们对白细胞弹性蛋白酶、组织蛋白酶G和α-胰凝乳蛋白酶的抑制效应。其中，H-Arg-Glu-Tyr-Phe-OMe（eglin c 22-25）和H-Ser-Pro-Val-Thr-Leu-Asp-Leu-Arg-Tyr-OMe（eglin c 41-49）能抑制组织蛋白酶G和α-胰凝乳蛋白酶，但不能抑制白细胞弹性蛋白酶，而H-Thr-Asn-Val-Val-OMe（eglin c 60-63）能抑制白细胞弹性蛋白酶，但不能抑制组织蛋白酶G或α-胰凝乳蛋白酶，尽管eglin c对白细胞弹性蛋白酶、组织蛋白酶G和α-胰凝乳蛋白酶都具有强抑制作用。这些结果提示，eglin c与白细胞弹性蛋白酶、组织蛋白酶G和α-胰凝乳蛋白酶的相互作用部位可能各不相同。

  The protected hexadecapeptide ester corresponding to positions 11 through 26 of human α2-plasmin inhibitor fragment T-11, which consists of 26 amino acids and binds to the plasmin (ogen) lysine-binding site (s), was synthesized by assembling five peptide fragments by the azide method or the dicyclohexylcarbodiimide-N-hydroxybenzotriazole method.

  通过对五个肽片段采用叠氮法或二环己基碳二亚胺-N-羟基苯并三唑法进行组装，合成了与人类α2-纤溶酶抑制剂片段T-11的第11至26位对应的受保护十六肽酯，该片段由26个氨基酸组成，并与纤溶酶（原）赖氨酸结合位点（s）结合。
• Amino acids and peptides. XII. Synthesis of C-terminal decapeptide of bovine pancreatic ribonuclease A(RNase A) and its analogs and determination of their ability to reactivate des(121-124)RNase A.

  A decapeptide corresponding to the C-terminal sequence (residues 115-124) of bovine pancreatic ribonuclease A (RNase A) and four analogs in which Asp-121 is replaced by Asn, Glu, Gln and Ala were synthesized by the fragment condensation procedure, and their abilities to reactivate RNase A from which the last 4 residues, Asp-Ala-Ser-Val, had been removed were examined. Asp-decapeptide (I) and Glu-decapeptide (III) bound with inactivated RNase 1-120 non-covalently and exhibited hydrolytic activity towards cyclic 2', 3'-cytidylic acid. In contrast, Asn-decapeptide (II), Gln-decapeptide (IV) and Ala-decapeptide (V) did not show any ability to restore the activity of RNase A 1-120. Our systematic syntheses of the C-terminal decapeptide of RNase A and its analogs indicate a very important role of the free carboxyl group at position 121 of RNase A for manifestation of RNase activity.

  合成了一种与牛胰腺核糖核酸酶A（RNase A）C端序列（残基115-124）相对应的十肽，以及四种其类似物，其中天冬酸-121被天冬酰胺、谷氨酸、谷氨酰胺和丙氨酸替代，并通过片段缩合程序合成了这些肽。研究了这些肽恢复从中去除了最后4个残基（天冬酸-丙氨酸-丝氨酸-缬氨酸）的RNase A的能力。天冬氨酸十肽（I）和谷氨酸十肽（III）以非共价方式与失活的RNase 1-120结合，并表现出对环状2', 3'-胞苷酸的水解活性。相比之下，天冬酰胺十肽（II）、谷氨酰胺十肽（IV）和丙氨酸十肽（V）没有显示出恢复RNase A 1-120活性的能力。我们系统合成的RNase A C端十肽及其类似物表明，第121位自由羧基在RNase活性的表现中扮演了非常重要的角色。

  The hexacosapeptide corresponding to the entire amino acid sequence of human α2-plasmin inhibitor fragment T-11 was synthesized by a conventional solution method. Three newly synthesized fragments were combined successively with the protected C-terminal hexadecapeptide ester previously obtained by using the dicyclohexylcarbodiimide-N-hydroxybenzotriazole and azide procedures to afford the protected hexacosapeptide ester. The trifluoromethanesulfonic acid-thioanisole-trifluoroacetic acid procedure was employed to remove all protecting groups of the protected peptide ester at the final stage. The dissociation constant for the interaction between the synthetic α2-plasmin inhibitor fragment T-11 and plasmin was equal to that of the native T-11 from human α2-plasmin inhibitor.

  用常规的溶液法合成了对应于人α2-纤溶酶抑制剂T-11片段全部氨基酸序列的六十六肽。先后将三个新合成的片段与预先用二环己基碳二亚胺-N-羟基苯并三唑和叠氮化物法制备得到的被保护的C端十六肽酯组合在一起，得到了被保护的六十六肽酯。在最终阶段用三氟甲磺酸-噻吩-三氟乙酸法去除被保护的肽酯的所有保护基团。合成的人α2-纤溶酶抑制剂T-11片段与纤溶酶相互作用的解离常数，等于天然的人α2-纤溶酶抑制剂中的T-11片段的解离常数。
