beta-Adrenergic blocking agents. 16. 1-(Acylaminomethyl-, ureidomethyl-, and ureidoethylphenoxy)-3-amino-2-propanols.

The synthesis of a series of 1-(acylaminomethyl-, ureidomethyl-, and ureidoethylphenoxy)-3-amino-2-propanols is described. The compounds were screened as beta-adrenergic receptor antagonists in cats and their partial agonist activity was evaluated in rats depleted of circulating catecholamines. Some of the compounds have a pharmacological profile similar to atenolol. Their structure-activity relationships are discussed.
