New β-adrenoceptor-blocking agents derived from dicyclopropyl ketone oxime: influence of amino substituents on in vivo activity
摘要:
A series of oximinopropanolamines derived from dicyclopropyl ketone, in which the amine substituents were alkyl, cycloalkyl, aryl and aralkyl groups, has been synthesized. The beta-adrenergic blocking properties were determined on anaesthetized rats. Two N-aralkyl derivatives were found to be as potent as propranolol and compound 11 was twice as active as propranolol. Some structure-activity relationships are discussed.
We describe the synthesis and pharmacological properties of two new series of aliphatic and alicyclic beta-adrenergic blockers, most of them containing a cyclopropyl ring. They belong either to 2-hydroxy-3-(tert-butylamino)propyl ether A or 2-hydroxy-3-tert-(butylamino)propyl ketoxime ether B derivatives. The O-[2-hydroxy-3-(tert-butylamino)propyl] dicyclopropyl ketoxime 5 exhibited a beta-adrenergic

A novel series of 31 N-aryl dicyclopropyl ketone oximeethers were synthesized and tested for their activity at alpha- and beta-adrenergic receptors. All of the compounds showed greater affinity for beta-than for alpha1-receptor sites. Some compounds had pure antagonist effects whereas some were partial agonists. Several compounds had an antagonist effect matching that of propranolol in in vitro (binding

Novel derivatized alkanolamines of the following structural formula
are described as useful cardiovascular agents. Most especially described is their usefulness as cardiovascular agents exhibiting an antiarrhythmic effect. Said antiarrhythmic effect is of a combination Class II/Class III variety. Pharmaceutical formulations containing such compounds are also described.

Several (aryloxy)propanolamines and related compounds (i.e. 5-13, 16-18, 20-24, 27-33, 35, 37-39, 41, and 42) were synthesized and investigated for their class III electrophysiological activity and class II (beta-blocking) effects with use of in vitro and in vivo models. Structure-activity relationships are discussed for a series of 30 compounds. A number of these compounds prolonged the action potential duration at 95% repolarization of isolated canine cardiac Purkinje fibers by 20% (C20APD95) at concentrations of less than 1.0 microM, with no significant effects on cardiac conduction. beta-Adrenergic receptor binding studies showed that some of these compounds were 2-20 times more potent for cardiac beta 1 receptors than for beta 2 receptors. In particular, compounds 32, 41, 1, and especially (S)-1 were found to be orally active class III agents in anesthetized mongrel dogs (1 or 3 mg/kg, id) and efficacious at suppressing programmed electrical stimulation induced arrhythmias in halothane-anesthetized dogs. The profile of these compounds was similar to that found for sotalol. Compound (S)-1, which was more potent than sotalol in the PES study and equieffective in the halothane/epinephrine dog model, is being investigated further as a combined class III/II antiarrhythmic agent.
