Abstract: A novel series of matriptase inhibitors based on previously identified tribasic 3-amidinophenylalanine derivatives was prepared. The C-terminal basic group was replaced by neutral residues to reduce the hydrophilicity of the inhibitors. The most potent compound 22 inhibits matriptase with a K(i) value of 0.43 nM, but lacks selectivity towards factor Xa. By combination with neutral N-terminal sulfonyl residues several potent thrombin inhibitors were identified, which had reduced matriptase affinity.
