- Abstract
- Owing to the beneficial health effects on human cardiovascular system, soybeans and soy-related products have been a focus of intensive research. Soy isoflavones are known to be primarily responsible for the soy-related biological effects including anti-platelet activity but its in vivo relevancy has not been fully verified. Here we compared the role of adenosine, an active ingredient abundant in black soybean (BB) extract, in the anti-platelet effects of BB, to that of soy isoflavones. At the concentrations existing in BB, isoflavones such as genistein and daidzein could not attenuate collagen-induced platelet aggregation, however, adenosine significantly inhibited platelet aggregation with an equivalent potency to BB, suggesting that adenosine may be the major bioactive component. Consistently, the anti-aggregatory effects of BB disappeared after treatment of adenosine receptor antagonists. The effects of BB are mediated by adenosine through intracellular cAMP and subsequent attenuation of calcium mobilization. Of note, adenosine and BB significantly reduced platelet fibrinogen binding and platelet adhesion, other critical events for platelet activation, which were not affected by isoflavones. Taken together, we demonstrated that adenosine might be the major active ingredient for BB-induced anti-platelet activity, which will shed new light on the roles of adenosine as a bioactive compound in soybeans and soy-related food.
