ABSTRACT
Objective To evaluate the anti-platelet aggregation effect of ergosterol in vitro and explore the preliminary mechanism. Methods The anti-platelet aggregation activity of ergosterol was assessed in vitro on rabbit platelet aggregation. Different inducers, ADP ( 4 μmol?L-1 ) , collagen ( 4 μg?mL-1 ) , arachidonic acid ( AA, 1 mmol?L-1 ) and thrombin (0.5 U?mL-1), and blockers (ozagrel, dipyridamole, clopidogrel and aspirin) were applied to observe the potential targets of ergosterol, platelet aggregation induced by ADP (0, 1, 2, 4, 6μmol?L-1) or fibrinogen (0, 1, 2, 4, 6, 10 mg?mL-1). Results Ergosterol exhibited an obvious anti-platelet aggregation effect in vitro with IC50 values on different inducers ( ADP, collagen, AA and thrombin) of (19.3±0.8), (23.4±1.2), (26.7±0.7), (32.9±1.5) μmol?L-1, respectively. Conclusion Ergosterol can significantly inhibit aggregation and activation of platelet. It provides experimental basis for full exploration of ergosterol and development of novel anti-platelet aggregation drugs.
