  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。

  A nonapeptide, H-Ser-Pro-Val-Thr-Leu-Asp-Leu-Arg-Tyr-OH, corresponding to sequence 41-49 of eglin c inhibited leukocyte cathepsin G and α-chymotrypsin with Ki values of 2.2×10-5 and 7.2×10-6M, respectively, although eglin c itself inhibited leukocyte elastase, cathepsin G and α-chymotrypsin with Ki values of 6.0×10-9, 5.5×10-9 and 2.5×10-9M, respectively. The inhibitory activity of the nonapeptide decreased following incubation with cathepsin G due to the cleavage of the Leu45-Asp46 peptide bond. Therefore, Leu45 and/or Asp46 were replaced with D-amino acids and the inhibitory activities of the resultant nonapeptides were examined. Their inhibitory activities against cathepsin G and α-chymotrypsin were much weaker than those of the all-L-type nonapeptide, suggesting that the amino acids at the active site, Leu45 and Asp46 are required to be in the L-configuration for potent activity.

  一种非apeptide，H-Ser-Pro-Val-Thr-Leu-Asp-Leu-Arg-Tyr-OH，对应于eglin c序列41-49，分别以2.2×10-5和7.2×10-6M的Ki值抑制白细胞组织蛋白酶G和α-胰凝乳蛋白酶，尽管eglin c本身分别以6.0×10-9、5.5×10-9和2.5×10-9M的Ki值抑制白细胞弹性蛋白酶、组织蛋白酶G和α-胰凝乳蛋白酶。非apeptide的抑制活性在与组织蛋白酶G孵育后下降，这是由于Leu45-Asp46肽键的断裂。因此，Leu45和/或Asp46被替换为D-氨基酸，并对产生的非apeptide的抑制活性进行了检查。它们对组织蛋白酶G和α-胰凝乳蛋白酶的抑制活性远弱于所有L型非apeptide，表明活性位点上的氨基酸，Leu45和Asp46，需要处于L-构型才能发挥强大活性。

  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。

  found to be an excellent coupling reagent having a water-soluble property and a high reactivity; it worked as satisfactory as usual active esters in regard to the reactivity, product purity, and racemization. The marked advantage of the HODMSP·MeSO4− active ester method was the fact that bifunctional residues such as Arg, Lys, Cys, and Tyr could be selectively acylated when the pH of the reaction mixture

  发现(对羟基苯基)二甲基锍甲基硫酸盐(HODMSP·MeSO4-)是一种优良的偶联剂，具有水溶性和高反应性；在反应性、产品纯度和外消旋化方面，它与通常的活性酯一样令人满意。HODMSP·MeSO4-活性酯法的显着优势在于，当反应混合物的pH值得到控制时，双功能残基如Arg、Lys、Cys和Tyr可以被选择性地酰化。通过这种新的活性酯方法合成了软体动物神经肽 FMRFamide（Phe-Met-Arg-Phe-NH2），以评估该方法在涉及肽合成的进一步应用中的应用。
