There is provided imidazodiazepines of the formula ##STR1## wherein A together with the two carbon atoms denoted as .alpha. and .beta. is the group ##STR2## X is an oxygen or sulphur atom and R.sup.1 is hydrogen or lower alkyl, and either R.sup.2 is hydrogen, trifluoromethyl, halogen, cyano or nitro and R.sup.3 is hydrogen or R.sup.2 is hydrogen and R.sup.3 is trifluoromethyl, halogen, cyano, nitro or lower alkyl, and their pharmaceutically acceptable acid addition salts. The compounds are useful in the antagonization of the central-depressant, muscle relaxant, ataxic, blood pressure-lowering and respiratory-depressant properties of 1,4-benzodiazepines which have tranquillizing activity, for example as antidotes in the case of intoxications with 1,4-benzodiazepines which have tranquillizing activity. Also presented are methods to produce the above imidazodiazepines.
提供了以下结构的咪唑二氮杂环丙烷类化合物:其中A与标记为α和β的两个碳原子一起是基团,X是氧原子或硫原子,R.sup.1是氢原子或低碳基,R.sup.2是氢原子、三氟甲基、卤素、氰基或硝基,R.sup.3是氢原子或R.sup.2是氢原子且R.sup.3是三氟甲基、卤素、氰基、硝基或低碳基,以及它们的药用可接受的酸盐。这些化合物可用于拮抗具有镇静作用的1,4-苯二氮杂环丙烷类化合物的中枢抑制、肌肉松弛、共济失调、降低血压和呼吸抑制特性,例如作为中毒1,4-苯二氮杂环丙烷类化合物的镇静活性的解毒剂。还提供了制备上述咪唑二氮杂环丙烷类化合物的方法。
