In Fort- >5 führung dieser Arbeiten wurde nun gefunden, daß die langanhaltende blutdrucksteigernde Wirkung dieser Körperklasse wesentlich von der in 2-StelIung substituierten Alkylgruppe abhängt, insbesondere ist die Dauer der blutdrucksteigernden Wirkung sehr viel länger, wenn man die Alkylkette verlängert. So wirken beispielsweise 0.5 mg/kg 2-PropyI-3,3-diphenylpropen-(2)-ylamin 30 bis 40 Minuten auf den Blutdruck der Katze in Urethan-Chloralose-Narkose, während 0,5 mg/kg 2-Butyl-3,3-diphenylpropen-(2)-ylamin eine Wirksamkeit bis zu 4 Stunden entfaltet.

In continuation of this work it has now been found that the long-lasting antihypertensive effect of this body class differs significantly from that in the 2-position substituted alkyl group depends, in particular, is the duration of the hypertensive effect much longer if you lengthen the alkyl chain. For example, 0.5 mg / kg of 2-propyI-3,3-diphenylpropen- (2) -ylamine act 30 to 40 minutes on the blood pressure of the cat under urethane-chloralose anesthesia, while 0.5 mg / kg of 2-butyl-3,3-diphenylpropen- (2) -ylamine is effective for up to 4 hours.
