In an effort to develop potent antiplatelet agents with anti-inflammatory action, a novel series of anti-inflammatory chalcones was screened to evaluate their antiplatelet effects. Structure-activity relationships and mode of action were investigated and characterized. The antiplatelet effects of the chalcones on washed rabbit platelets and human platelet-rich plasma were evaluated. Arachidonic acid-induced platelet aggregation was potently inhibited by almost all the chalcone derivatives. Collagen-induced platelet aggregation was potently inhibited by all the chalcone derivatives at 300 microM, except for compound 4 at 100 microM. Compounds 6, 7 and 9 significantly inhibited the aggregation of washed rabbit platelets induced by platelet-activating factor at 300 microM. Of the compounds tested in human platelet-rich plasma, compounds 2, 8 and 9 showed significant inhibition of secondary aggregation induced by adrenaline. It is concluded that the antiplatelet effect of 2, 8 and 9 is mainly owing to an inhibitory effect on thromboxane formation. The inhibitory effect of 6, 7 and 9 on platelet aggregation induced by platelet-activating factor could be owing to a calcium antagonizing effect or inhibition of intracellular calcium mobilization.

D010974 Platelet Aggregation The attachment of PLATELETS to one another. This clumping together can be induced by a number of agents (e.g., THROMBIN; COLLAGEN) and is part of the mechanism leading to the formation of a THROMBUS. Aggregation, Platelet
D010975 Platelet Aggregation Inhibitors Drugs or agents which antagonize or impair any mechanism leading to blood platelet aggregation, whether during the phases of activation and shape change or following the dense-granule release reaction and stimulation of the prostaglandin-thromboxane system.
