摘要

N-[2-Hydroxy-5-[2-(methylamino) ethyl] phenyl] methanesulfonamide (SK&F 102652) has been prepared and characterized pharmacologically. It is a potent agonist with an of 25 nM at al-adrenoceptors as determned in the isolated perfused rabbit ear artery. On the presynaptic a2-adrenoceptors of the guinea pig atrium it was considerably weaker, demonstrating an EC50 for inhibition of neurotransmission of 1200 nM and thus an overall ...
