Article abstract of DOI:10.1248/cpb.47.1685

The synthesis and design using molecular modeling techniques for non- peptide, low molecular weight novel fibrinogen receptor (glycoprotein IIb/IIIa: Gp IIb/IIIa) antagonists, is reported. We used a highly potent serine protease inhibitor, Nafamostat, having an amidinonaphthyl unit as the starting compound. The compounds 4-(6-amidino-2- naphthylaminocarbonyl)phenoxyacetic acid (5a) and 4-(6-amidino-2- naphthalenecarboxamido)phenoxyacetic acid (5b) inhibited adenosin-5'- diphospate (ADP)-induced aggregation of human platelet-rich plasma (PRP) with IC₅₀ values of 0,05 and 0.07 μM, respectively, and had lost their ability to inhibit a variety of serine proteases, including thrombin, factor Xa, plasmin and trypsin.
