quantitative yields. The alpha-keto tripeptides (18-21) were obtained by oxidation of the hydroxyl group of Apns (PI) in the appropriate tripeptide, iQOA-Val-Apns-(un)substituted Thz(Oxa)-NHBu(t) with DMSO/DCC. Preliminary evaluation of the activity of the synthesized derivatives was determined as percentage of enzyme inhibition at 5 microM and 50 nM levels of the di- and tripeptides respectively. The alpha-ketoamides
