Abstract
The effects of the anti-inflammatory serine esterase inhibitor, gabexate mesilate (Foy) were studied, on locomotion, autoaggregation and adhesion of polymorphonuclear leukocytes stimulated with the complement peptide C5a-desArg. The drug inhibited aggregation as well as spontaneous and directed migration of human leukocytes at concentrations of about 10−3 M. Adhesion of peritpneal guinea-pig leukocytes to autologous aortic strips was reduced at about 20 times lower drug concentrations. The inhibitory drug effects were highly time- and temperature-dependent. Experiments with the two major drug metabolites, pHB and εGC, indicate that gabexate mesilate is not active by itself but rather by its hydrolytic aromatic metabolite pHB. The results further suggest that the inhibitory effects on leukocyte activities observed are not related to the anti-inflammatory effects of gabexate mesilate.
