  Optically active 2-benzyl-3-methanesulfinylpropanoic acid: Synthesis and evaluation as inhibitors for carboxypeptidase A

  摘要：

  All four possible stereomers of 2-benzyl-3-methanesulfinylpropanoic acid were synthesized and evaluated as inhibitors for carboxypeptidase A to find that the isomer having the (2S,4S)-configuration is most potent followed by isomers of (2R,4S)- and (2S,4R)-configurations. The stereochemical preferences shown by the isomers of the inhibitor in binding to the enzyme suggest that the sulfoxide oxygen in the inhibitor fails to ligate the active site zinc ion but may form a hydrogen bond with the guanidinium moiety of Arg-127 like the carbonyl oxygen of scissile peptide bond of oligopeptide Substrate of the enzyme does. It may thus be inferred that a sulfoxide moiety may serve as an isosterer of a carboxamide moiety. (C) 2003 Elsevier Ltd. All rights reserved.
