摘要：

A series of peptidyl alpha-keto aldehydes (glyoxals) have been synthesised as putative inhibitors of the chymotryptic-like activity of proteasome. The most potent peptides, Cbz-Leu-Leu-Tyr-COCHO and Bz-Leu-Leu-Leu-COCHO, function as slow-binding reversible inhibitors, exhibiting final K-i values of approximately 3.0 nM. These are among the lowest values so far reported for (tri)peptide-based aldehyde-releated inhibitors. (C) 1998 Elsevier Science Ltd. All rights reserved.
