Abstract

Phentolamine (10(-5) M) and an inhibitor of the lipoxygenase pathway, nordihydroguaiaretic acid (N. D. G. A.; 8 10(-6) M) antagonized the ATP induced contraction but not antagonized the UTP induced contraction on both rat tail artery and dog saphenous vein. We conclude that the receptors to ATP are distinct from receptors to UTP and that the P2 purinoceptors are an heterogeneous group.
