The invention relates to novel N-alkylated aminoalcohols of the formula ##STR1## in which Ar is a radical of aromatic character which is unsubstituted or substituted by hydroxyl, n has the values nought or 1 and Alk is an alkylene radical having 2 to 5 carbon atoms and the nitrogen atom and the oxygen atom or, if n is nought, the salicylamide radical are separated from one another by at least two carbon atoms in the straight-chain, and their salts. The main action of the novel compounds consists in a stimulation of cardiac .beta.-receptors; the compounds also effect a blockage of adrenergic .alpha.-receptors and a lowering in the blood pressure. They can therefore be used as .beta.-stimulators, especially as agents having a positively inotropic action for the treatment of cardiac insufficiency. Compounds of the formula I in which Ar is phenyl, unsubstituted or substituted by 1 or 2 hydroxyl groups, Alk is an alkylene radical having 2 to 4 carbon atoms, n has the value 1, and the nitrogen atom and the oxygen atom are separated from one another by at least 2 carbon atoms in the straight-chain, or salts thereof, exhibit effects on the central nervous system, which are reflected for example in the suppression of the symptoms of impaired sympathetic functions and in the suppression of lack of initiative. Such compounds of the formula I therefore can be used for the treatment of reactive or endogenic states of depression of varying degrees of severity, and also for the treatment of neurotic or other psychic disturbances involving loss of initiative and depressive disorders. Such compounds can also be used for the short-term treatment of post-partum or postoperative depression, or of depression of different origin. Such compounds of the formula I can be used on their own or in combination with other antidepressants.
该发明涉及具有以下结构的新型N-烷基化氨基醇:##STR1##其中Ar是具有芳香性质的基团,未取代或被羟基取代,n的值为零或1,Alk是具有2至5个碳原子的烷基基团,氮原子和氧原子或者,如果n为零,则是水杨酰胺基团,在直链中至少被至少两个碳原子分开,以及它们的盐。这些新型化合物的主要作用在于刺激心脏β-受体;这些化合物还会阻断肾上腺素α-受体并降低血压。因此,它们可以用作β-激动剂,特别是作为具有正性肌力作用的药物,用于治疗心脏功能不全。其中Ar为苯基,未取代或被1或2个羟基取代,Alk是具有2至4个碳原子的烷基基团,n的值为1,氮原子和氧原子在直链中至少被至少2个碳原子分开,或其盐的化合物,对中枢神经系统产生影响,例如抑制受损交感神经功能的症状和抑制缺乏主动性。因此,这些具有结构I的化合物可用于治疗不同程度的反应性或内源性抑郁状态,以及用于治疗神经症或其他涉及缺乏主动性和抑郁障碍的精神紊乱。这些化合物还可用于短期治疗产后抑郁症或术后抑郁症,或不同起源的抑郁症。这些具有结构I的化合物可以单独使用或与其他抗抑郁药物联合使用。
