摘要

Phenoxypropanolamines with 1-oxo-isoindoline and 5,6-dimethoxy-1-oxo-isoindoline groups at the para position were synthesized. beta1, beta2-Adrenergic receptor binding affinities for the synthesized compounds were tested and compared with propranolol and atenolol. It was found that the incorporation of para-amidic functionality within the 1-oxo-isoindoline ring and 5,6-dimethoxy-1-oxo-isoindoline ring system led to a high degree of cardioselectivity in the phenoxypropanolamines. Two of the compounds and possessed beta1-adrenergic receptor affinity comparable with that of atenolol and both showed a better cardioselectivity than atenolol. Both and are undergoing further pharmacological evaluation.
