This invention relates to nitrogen-containing aromatic 5-membered ring-condensed benzazepine derivatives represented by the general formula (I) ##STR1## (symbols in the formula have the following meanings; ring B: a nitrogen-containing aromatic 5-membered ring having at least 1 nitrogen atom and optionally one oxygen or sulfur atom, which may optionally have substituent(s), R.sup.1 and R.sup.2 : these may be the same or different from each other and each represents a hydrogen atom, a halogen atom, a lower alkyl group, an amino group which may optionally be substituted by lower alkyl group(s), or a lower alkoxy group, A: a single bond; a group represented by the formula --NHCO--(CR.sup.3 R.sup.4).sub.n --, n: 0 or an integer of from 1 to 3, R.sup.3 and R.sup.4 : these may be the same or different from each other and each represents a hydrogen atom, a lower alkyl group (provided that R.sup.3 and R.sup.4 may together form a lower alkylene group having 2 to 7 carbon atoms), and ring C: a benzene ring which may optionally have substituent(s)) and salts thereof; to pharmaceutical compositions which contain these compounds as an active ingredient and to intermediates which are useful in synthesizing these compounds. The compounds of this invention are useful as arginine vasopressin antagonists.
这项发明涉及一般式(I)所代表的含氮芳香5-成员环-融合苯并哌嗪衍生物,其中##STR1##(式中符号的含义如下;环B:至少含有1个氮原子且可能有一个氧原子或硫原子的含氮芳香5-成员环,可以选择地具有取代基,R.sup.1和R.sup.2:它们可以相同也可以不同,每个代表氢原子、卤素原子、低烷基、可能被低烷基取代的氨基或低烷氧基,A:单键;一个由式--NHCO--(CR.sup.3 R.sup.4).sub.n --表示的基团,n:0或1至3的整数,R.sup.3和R.sup.4:它们可以相同也可以不同,每个代表氢原子、低烷基(条件是R.sup.3和R.sup.4可以一起形成具有2至7个碳原子的低烷基烯基),环C:可能具有取代基的苯环)及其盐;含有这些化合物作为活性成分的药物组合物;以及在合成这些化合物中有用的中间体。本发明的化合物可用作精氨酸加压素拮抗剂。
