title: Synthesis, binding affinity and selectivity of new beta 1- and beta 2-adrenoceptor blockers.
abstract: The synthesis of a new series of sesamol derivatives with beta-adrenergic blocking activity is described. The affinity and selectivity of these compounds for beta 1- and beta 2-adrenoceptors were studied in comparison with those of ICI-118551 and propranolol. Some of the synthesized compounds show very good affinity for the beta 2-receptors of rat lung membranes and two of them provide interesting selectivity.
