1 The beta-adrenoceptors had some of the characteristics of mammalian beta 2-adrenoceptors in that (i) adrenaline was more potent than noradrenaline and (ii) the pA2 values of two selection beta-adrenoceptor antagonists, atenolol (pA2 = 5.84) and alpha-methylpropranolol (pA2 = 8.42), were close to the values reported on beta 2-adrenoceptors in mammalian tissues.
