  • PubMed Abstract: 
  • A putative non-substrate like binding mode of (R)-3-amidinophenylalanine derivatives to factor Xa, as derived from modeling experiments based on X-ray analysis of their complexes with trypsin, was used to design a new generation of inhibitors. However, the resulting inhibitory potencies were not at all consistent with the working assumption, although with an adamantyl-ureido derivative of (R)-3-amidinophenylalanine phenetyl amide a highly selective nanomolar inhibition of factor Xa was achieved ...

    A putative non-substrate like binding mode of (R)-3-amidinophenylalanine derivatives to factor Xa, as derived from modeling experiments based on X-ray analysis of their complexes with trypsin, was used to design a new generation of inhibitors. However, the resulting inhibitory potencies were not at all consistent with the working assumption, although with an adamantyl-ureido derivative of (R)-3-amidinophenylalanine phenetyl amide a highly selective nanomolar inhibition of factor Xa was achieved. The X-ray analysis of the complex of this ligand with factor Xa revealed an unexpected new binding mode, of which the most important feature is the interaction of the C-terminal aryl moiety with a hydrophobic subregion of the S1 subsite, while the adamantyl group occupies the hydrophobic S3/S4 subsites of the enzyme.
