Auranofin (AF), at a concentration of 10?g/ml, was found to be a potent inhibitor of ADP-, epinephrine-, or collagen-induced platelet aggregation utilizing platelet-rich plasma obtained from human blood. In contrast, aurothioglucose was less effective than AF in inhibiting epinephrine- or collagen-induced platelet aggregation. The inhibitory effect of AF was more evident on the second phase of aggregation and was a function of drug preincubation time. Compared to platelet-rich plasma, washed platelets were superior for detecting the inhibitory action of AF (?0.1 ?g/ml) on ADP-induced platelet aggregation. This potent inhibitory action of AF on ADP-induced platelet aggregation was antagonized by dithioerythriol, a potent reducing agent. These results suggest that AF can inhibit both platelet release and aggregation mechanisms which may be relevant to its antiarthritic activity. Further studies are required to elucidate the cellular mechanism by which AF inhibits platelet aggregation. |
