New low-molecular inhibitors of pancreatic elastase with possible in vivo application: Alkylamides of N-acylated tripeptides

Out of a series of alkylamides of N-acylated tripeptides, Glt-(Ala)2-Pro-NH-Et and Glt-(Ala)3-NH-Pr were found to be potent inhibitors of porcine and human pancreatic elastase, and because they are free of toxic groups they might be considered for in vivo application.
