1-(2-Cyanophenyloxy)-3-(hydroxyindolylalkylamino)-2-propanols and their salts are cardiovascular agents having promise as antihypertensive agents by virtue of their vasodilating and adrenergic receptor blocking actions. Preferred compounds contain the 3-indolyl-tertiary-butylamino moiety. The compounds have the formula <IMAGE> wherein one of R<1> and R<2> is hydrogen and the other is hydrogen or C1-4 alkyl; R<3> and R<4> are independently selected from hydrogen or C1-4 alkyl; R<5> is halogen, hydrogen, hydroxy, or C1-4 alkyl;o |
