The esters of phenylalkanoic acid of the formula: ##STR1## wherein R.sup.1 is 4-10 membered, saturated or unsaturated, mono- or bi-cyclic hetero ring containing as hetero atoms: (i) one or two nitrogen, (ii) two or three of nitrogen and sulfur in total, or (iii) one or two sulfur; R.sup.2 is hydrogen; or R.sup.1 and R.sup.2, taken together with a nitrogen to which they are attached, form 4-7 membered, saturated or unsaturated, mono-cyclic hetero ring containing as hetero atoms: (i) one or two nitrogen, or (ii) two or three of nitrogen and oxygen in total, the aforementioned hetero rings, represented by R.sup.1 or formed by R.sup.1 and R.sup.2, taken together with a nitrogen to which they are attached, may be substituted by one substituent selected from C1-4 alkyl and C2-5 acyl; R.sup.3 each, independently, is hydrogen or C1-4 alkyl; R.sup.4 is hydrogen, halogen, trihalomethyl, C1-4 alkyl, C1-4 alkoxy, C2-5 acyl, cyano, nitro or nitroxy; R.sup.5 each, independently, is hydrogen, C1-4 alkyl or phenyl; or the two R.sup.5 's, taken together with a carbon to which they are attached, form cyclopentane or cyclohexane; and the pharmaceutically acceptable acid addition salts thereof, have .beta..sub.1 -adrenergic receptor blocking activity, and therefore, are useful for the prevention of and/or in the treatment of cardiovascular diseases such as angina pectoris, myocardial infarction, congestive heart failure, hypertension, arrhythmia, etc.
公式:##STR1## 其中 R.sup.1 是4-10个成员、饱和或不饱和、单环或双环杂环,含有杂原子:(i) 一个或两个氮,(ii) 总共两个或三个氮和硫,或(iii) 一个或两个硫; R.sup.2 是氢; 或者R.sup.1和R.sup.2与它们附着的氮一起形成4-7个成员、饱和或不饱和、单环杂环,含有杂原子:(i) 一个或两个氮,或(ii) 总共两个或三个氮和氧,上述由R.sup.1表示或由R.sup.1和R.sup.2形成的杂环,与它们附着的氮一起,可以被一个选自C1-4烷基和C2-5酰基的取代基所取代; R.sup.3各自独立地是氢或C1-4烷基; R.sup.4是氢、卤素、三卤甲基、C1-4烷基、C1-4烷氧基、C2-5酰基、氰基、硝基或亚硝基; R.sup.5各自独立地是氢、C1-4烷基或苯基; 或者两个R.sup.5,与它们附着的碳一起,形成环戊烷或环己烷; 这些化合物的药物可接受的酸盐具有β1-肾上腺素能受体阻滞活性,因此,对于预防和/或治疗心血管疾病如心绞痛、心肌梗死、充血性心力衰竭、高血压、心律失常等非常有用。
