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
The synthesis of R-(+) and S-(-) isomers of O-[3-tert-butylamino)-2-hydroxypropyl] cyclopropyl methyl ketone oxime (falintolol) is described. The syn and anti isomers of falintolol were obtained in two different ways from cyclopropyl methyl ketoxime or from falintolol. For comparison purposes, the enantiomers of the dicyclopropyl ketone oxime derivatives were also prepared. Structure-activity relationships
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.
