摘要:
Neue Derivate des 2-Aminoäthanols der Formel in welcher Ar gegebenenfalls substituiertes Phenyl, m eine Zahl von 0 bis 3, n die Zahl 0 oder 1 und alk Alkylen mit 2-5 Kohlenstoffatomen bedeuten, wobei das Stickstoffatom und das Sauerstoffatom oder, falls n für Null steht, der Phenylrest durch mindestens zwei Kohlenstoffatome voneinander getrennt sind, und R, und R 2 unabhängig voneinander je Wasserstoff oder Niederalkyl, oder zusammen Niederalkylen, Oxaniederalkylen, Thianiederalkylen, Azaniederalkylen oder N-Niederalkylazaniederalkylen darstellt mit der Massgabe, das falls m für 0 steht, der Phenylrest Ar mindestens einen Substituenten enthält, und ein durch eine oder zwei Hydroxygruppen oder geschützte Hydroxygruppen substituierter Phenylrest Ar mindestens einen zusätzlichen, von diesen verschiedenen Substituenten enthält, in der Form von Racematgemischen, Racematen, optischen Antipoden oder deren Salzen. Solche Verbindungen wirken teilweise als Blocker, teilweise als Stimulatoren von β-adrenergen Rezeptoren mit mehr oder weniger ausgeprägter Cardioselektivität und können demnach einesteils bei den für β-Blocker üblichen Indikationen, anderenteils zur Behandlung der insuffizienten Herzleistung, von Asthma und Durchblutungsstörungen eingesetzt werden.
