This invention relates to novel benzodiazepine derivatives represented by the following general formula (I) or pharmaceutically acceptable salts thereof, ##STR1## (wherein R.sup.1 is an aryl group, or an aromatic heterocyclic radical of 5-membered monocyclic, 6-membered monocyclic or 5- and 6-membered bicyclic structure, which may optionally be substituted; and R.sup.2 is an aryl group which may optionally be substituted), to medicinal compositions comprising the same, and to a process for producing the same. The compounds of formula (I) shown above exhibit antagonism for the CCK-B receptor and the action of depressing the gastric acid secretion caused by the stimulus of pentagastrin, and are therefore useful as a drug for the relief of diseases related to the CCK-B receptor and the gastrin receptor.
本发明涉及以下一般式(I)所表示的新型苯二氮平衍
生物或其药学上可接受的盐,其中R1是芳基或5元单环、6元单环或5-和6元双环结构的芳香杂环基团,可以选择性地被取代;R2是可以选择性地被取代的芳基基团。本发明还涉及包含上述化合物的医药组合物以及制备上述化合物的方法。上述式(I)的化合物表现出对CCK-B受体的拮抗作用和抑制由五胃肽刺激引起的胃酸分泌作用,因此可用作缓解与CCK-B受体和胃泌素受体相关疾病的药物。
