摘要:
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.
