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 ##STR2## 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 --(CH.sub.2).sub.4 -- (b) or --CH.dbd.CH--CH.dbd.CH--, (c) 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.
公式为##STR1##的Phenoxy-aminopropanol衍生物,其中R为较低的烷基,X为氧或硫,n为整数零或1,Y为亚甲基,乙烯基或丙烯基,或者当n为零时,Y也可以是一个公式##STR2##中的一个基团,其中双键为反式,带星号的碳原子与Z连接,Z为一个5-成员芳香杂环环,其中包含一个或多个氮原子作为唯一的杂原子(S),所述杂环环通过氮原子与Y连接,并且可以被卤素,较低的烷基,较低的烷氧基,芳基,氰基或羧酰胺基取代,或在相邻的碳原子上由公式--(CH.sub.2).sub.4--(b)或--CH.dbd.CH--CH.dbd.CH--(c)的基团取代,并且其药物可接受的酸盐也被描述。还描述了制备公式I化合物和含有它们的制药制剂的过程。上述化合物和盐具有β-肾上腺素能阻滞活性和降压活性。
