Inhibitory Effects of Dimeric Copper(II) bis(o-acetoxybenzoate) on Platelet-neutrophil adhesion and Thrombosis

Abstract:
Antithrombotic effect of the copper-aspirin complex (dimeric copper(II) bis(o-acetoxybenzoate) was evaluated in the model of venous thrombosis; its effects on platelet-neutrophil adhesion were investigated by use of rosette assay. The results showed that the intragastrically administered copper-aspirin complex (5, 7, and 10 mg kg(-1)) dose-dependently lowered the wet and dry thrombus weight; it significantly decreased the binding of arachidonic acid-activated platelets to neutrophils with an IC(50) value of 41.5 mumol L(-1). The results suggested that copper aspirinate inhibited platelet-neutrophil adhesion and resulted in a more potent antithrombotic activity.
