Compounds of the general formula: ##STR1## in which A is a benzene ring or a carbocyclic aromatic group consisting of two or three fused benzene rings, the group A being linked to the nitrogen containing ring at two adjacent carbon atoms and the benzene ring or each benzene ring optionally carrying one or more substituents which may be the same or different, and may be alkyl, aryl, halo, hydroxy, acyloxy or alkoxy, or two adjacent positions in a ring may be substituted so as to form a methylene dioxy group (--O--CH.sub.2 --O--); R.sub.1 and R.sub.2 which may be the same or different, each represent hydrogen; an alkyl group which contains 1 to 6 carbon atoms and which may be substituted; a hydroxycarbonyl or an alkoxycarbonyl group; and one of R.sub.3 and R.sub.4 represents hydrogen, an alkyl group which contains 1 to 6 carbon atoms and which may be substituted, or a hydroxy, alkoxy, hydroxycarbonyl or alkoxycarbonyl group and the other of R.sub.3 and R.sub.4 represents hydrogen, or a non-toxic physiologically acceptable salt or bioprecursor thereof. These compounds are useful in the treatment of patients suffering from depression.
通式为:##STR1##其中A是苯环或由两个或三个融合苯环组成的碳环芳基基团,基团A与含氮环相连的两个相邻碳原子上,苯环或每个苯环可选地携带一个或多个取代基,这些取代基可以相同或不同,可以是烷基、芳基、卤素、羟基、酰氧基或烷氧基,或者环中的两个相邻位置被取代形成亚甲二氧基基团(-O-CH.sub.2-O-); R.sub.1和R.sub.2 可以相同也可以不同,分别代表氢原子; 包含1至6个碳原子且可以被取代的烷基; 羟基羧酸酯或烷氧羧酸酯基团; R.sub.3和R.sub.4中的一个代表氢原子,包含1至6个碳原子且可以被取代的烷基,或羟基、烷氧基、羟基羧酸酯或烷氧羧酸酯基团,而R.sub.3和R.sub.4中的另一个代表氢原子,或其无毒生理可接受的盐或生物前体。这些化合物在治疗患有抑郁症的患者中具有用途。
