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.
本发明涉及氮含量芳香族5-成员环缩合苯并氮杂环衍生物,其由通式(I)表示:##STR1##(式中符号的含义如下:环B:至少有1个氮原子和可选的一个氧原子或硫原子的氮含量芳香族5-成员环,可以可选地具有取代基;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、低碳基、氨基(可以选择地被低碳基取代)或低碳氧基;A:单键;由式--NHCO--(CR.sup.3R.sup.4).sub.n --表示的基团,其中n为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、低碳基(前提是R.sup.3和R.sup.4可以共同形成具有2至7个碳原子的低碳烯基基团),环C:苯环,可以可选地具有取代基)及其盐;以这些化合物作为活性成分的药物组合物;以及用于合成这些化合物的中间体。本发明的化合物可用作精氨酸加压素拮抗剂。
