  名称：

  4-Acetamidophenyl esters and 4-acetamidoanilides of L-arginine,p-guanidino-L-phenylalanine, L-lysine, N2-[D-fructos-3-O-yl and D-glucos-3-O-yl]acetyl-L-lysine as potential acrosin inhibitors

  摘要：

  Syntheses of 4-acetamidophenyl esters and 4-acetamidoanilides of L-lysine,p-guanidino-L-phenylalanine, L-leucyl-L-lysine, L-leucyl-L-leucyl-L-lysine, N2-[(1,2-O-isopropylidene-alpha-D-glucofuranos-3-O-yl)acetyl]-L-lysine, N2-[(1,2-O-isopropylidene-beta-D-fructopyranos-3-O-yl)acetyl]-L-lysine are reported. 4-Acetamidophenyl L-argininate was too unstable to be isolated but L-arginin-4-acetamidoanilide was prepared. These amino acid and peptide derivatives proved to be enantiomerically pure and were characterized by their H-1 and C-13 chemical shifts which were established by means of multipulse 1D and 2D NMR techniques. Preliminary evaluation showed these compounds to be relatively weak inhibitors of human acrosin and bovine trypsin.
