Phenoxy-aminopropanol derivatives of the formula ##STR1## wherein R is lower alkyl, X is oxygen or sulfur, n is the integer zero or 1, Y is methylene, ethylene or propylene or, when n is zero, Y can also be a group of the formula --CH.dbd.CH--C*H.sub.2 -- (a) , wherein the double-bond is trans and the carbon atom marked with an asterisk is linked to Z, and Z is a 5-membered aromatic heterocyclic ring which contains one or more nitrogen atoms as the sole hetero atom (s), said heterocyclic ring is linked to Y via a nitrogen atom, and may be substituted by halogen, lower alkyl, lower alkoxy, aryl, cyano or carboxamido, or on adjacent carbon atoms by a group of the formula ##STR2## and pharmaceutically acceptable acid addition salts thereof are described. A process for the preparation of the compound of formula I and pharmaceutical preparations containing them are also described. The aforementioned compounds and salts possess .beta.-adrenergic blocking activity and antihypertensive activity.
Phenoxy-aminopropanol衍生物的结构式为##STR1##其中R是较低的烷基,X是氧或硫,n是整数零或1,Y是亚甲基,乙烯基或丙烯基,或者当n为零时,Y也可以是一个结构式为--CH.dbd.CH--C*H.sub.2--(a)的基团,其中双键为反式,带有星号标记的碳原子与Z连接,Z是一个含有一个或多个氮原子作为唯一杂原子的5-成员芳香杂环环,该杂环通过氮原子与Y连接,并且可以被卤素、较低烷基、较低烷氧基、芳基、氰基或羧酰胺基替代,或者在相邻碳原子上被结构式为##STR2##的基团替代,以及其药学上可接受的酸盐。还描述了一种制备式I化合物的方法和含有它们的药物制剂。上述化合物和盐具有β-肾上腺素能阻滞活性和降压活性。
