In an effort to prepare novel inhibitors of bacterial aminopeptidase N (PepN), the phosphinate, propenylphosphinate, decylphosphinate, sulfonate, and sulfonamidate analogs of Ala-Ala were synthesized and tested as inhibitors. Phosphinate I was shown to inhibit PepN with a K-i of 10 mu M, and propenylphosphinate 2 and decylphosphinate 3 inhibited PepN with a K-i of ca. 1 mu M. Sulfonate and sulfonamidate analogs did not inhibit PepN. (c) 2005 Elsevier Ltd. All rights reserved.
