The invention relates to novel substituted phenyl ethers of the formula ##STR1## in which Ar represents a mono- or bi-cyclic carbocyclic aryl radical, or a mono- or bi-cyclic heterocyclic aryl radical bonded to a phenylene radical by way of a ring carbon atom, Ph represents a phenylene radical, n has the value 0 to 1 and alk represents alkylene having from 2 to 5 carbon atoms, the nitrogen atom and the oxygen atom or, if n is 0, the aromatic radical being separated from each other by at least two carbon atoms in the unbranched chain, and R.sub.1 and R.sub.2 each represents, independently of the other, hydrogen or lower alkyl, or together represent lower alkylene, oxa-lower alkylene, thia-lower alkylene, aza-lower alkylene or N-lower alkyl-aza-lower alkylene, and salts thereof, especially pharmaceutically acceptable non-toxic acid addition salts. Such compounds possess, on the one hand, blocking properties towards .beta.-adrenergic receptors and can therefore be used as .beta.-receptor-blockers with or without cardioselectivity for the treatment of Angina pectoris, hypertrophic cardiomyopathy and heart rhythm disorders and also as blood-pressure-reducing agents. On the other hand, such compounds possess .beta.-receptor-stimulating properties and can therefore be used as positively inotropically active agents, especially as cardiotonics, for the treatment of heart muscle insufficiency.
该发明涉及新型取代苯醚化合物,其化学式为##STR1##其中Ar代表单环或双环碳环芳基,或通过环碳原子与苯基相连的单环或双环杂环芳基,Ph代表苯基,n取值为0至1,alk代表具有2至5个碳原子的烷基,氮原子和氧原子或者如果n为0,则芳基在直链中至少被至少两个碳原子分隔,R.sub.1和R.sub.2分别独立地代表氢或低烷基,或者一起代表低烷基,氧杂低烷基,硫杂低烷基,氮杂低烷基或N-低烷基-氮杂低烷基,以及其盐,特别是药学上可接受的无毒酸盐。这类化合物一方面具有对β-肾上腺素受体的阻滞作用,因此可用作具有或不具有心脏选择性的β-受体阻滞剂,用于治疗心绞痛、肥厚型心肌病和心律失常,也可用作降压药。另一方面,这类化合物具有β-受体激动作用,因此可用作具有正肌力作用的药剂,特别是作为心力衰竭的治疗药物。
