The synthesis of (2RS)-1-(1H-indol-4-yloxy)-3-[2-(2-methoxyphenoxy)ethyl]amino}propan-2-ol ((RS)-9) and its enantiomers has been described and tested for electrocardiographic, antiarrhythmic, hypotensive and spasmolytic activities as well as for α1-, α2- and β1-adrenoceptors' binding affinities. All compounds significantly decrease systolic and diastolic blood pressure, and possess antiarrhythmic
