H-Ser-Pro-Val-Thr-Leu-Asp-Leu-Arg-Tyr-OH and H-Thr-Asn-Val-Val-OH, which correspond to the sequences 41-49 and 60-63 of eglin c, respectively, were synthesized by a conventional solution approach using the newly developed 6-chloro-2-pyridyl ester method. The inhibitory activities of the above two peptides against human leukocyte elastase, cathepsin G, porcine pancreatic elastase and α-chymotrypsin were examined in comparison with those of the corresponding methyl esters.
                                    H-Ser-Pro-Val-Thr-Leu-Asp-Leu-Arg-Tyr-OH 和 H-Thr-Asn-Val-Val-OH 分别对应于 eglin c 的序列 41-49 和 60-63,通过采用新开发的 6-
