title: Amino acids and peptides. XXX. Synthesis of eglin c (41-49) and eglin c (60-63) and examination of their inhibitory activity towards human leukocyte elastase, cathepsin G, porcine pancreatic elastase and alpha-chymotrypsin.
abstract: 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 alpha-chymotrypsin were examined in comparison with those of the corresponding methyl esters.
