Inhibition of PGE1-stimulated cAMP accumulation in human platelets by thromboxane a2
Abstract
The prostaglandin endoperoxide PGH2, HHT, HETE, thromboxane A2, and thromboxane B2, which are all products of arachidonic acid metabolism of human platelets, were tested for their ability to modulate platelet cyclic nucleotide levels. None of the compounds tested altered the basal level of cAMP or cGMP, and only PGH2 and thromboxane A2 inhibited PGE1-stimulated cAMP accumulation. Thromboxane A2 was found to be a more potent inhibitor of PGE1-stimulated cAMP accumulation and inducer of platelet aggregation than PGH2.
