title: Synthesis and pharmacological evaluation of propranolol-cyclic analogues.
abstract: Three propranolol analogues, bearing the oxygen of the --OH group enclosed in a 1,4-dioxanic rigid system, were synthetized. The lack of beta-blocking activity found for these compounds demonstrates the important role played by a free--OH group in the drug-receptor interaction.
