There is provided imidazodiazepines of the formula ##STR1## wherein R.sup.1 is methyl, ethyl or isopropyl, one of R.sup.4 and R.sup.5 is hydrogen and the other is nitro or cyano, and either R.sup.2 is hydrogen and R.sup.3 is hydrogen or lower alkyl or R.sup.2 and R.sup.3 together are dimethylene, trimethylene or propenylene and the carbon atom denoted as .gamma. has the (S)-- or (R,S)-- configuration, and X is an oxygen or sulphur atom, 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. They can also be used for suppressing the activities on the central nervous system of 1,4-benzodiazepines used in other fields of indication, for example of schistosomicidally-active 1,4-benzodiazepines. Also provided are methods for making the compounds.
提供了公式为##STR1##的咪唑二氮杂环己烷衍生物,其中R.sup.1为甲基、乙基或异丙基,R.sup.4和R.sup.5中的一个为氢,另一个为硝基或氰基,R.sup.2为氢,R.sup.3为氢或较低的烷基,或者R.sup.2和R.sup.3一起为二甲基、三甲基或丙烯基,标记为γ的碳原子具有(S)-或(R,S)-构型,X为氧或硫原子,以及它们的药学上可接受的酸盐。这些化合物在对抗具有镇静作用的1,4-苯二氮杂环己烷的中枢抑制性肌肉松弛、共济失调、降低血压和呼吸抑制性能方面很有用。它们还可用于抑制1,4-苯二氮杂环己烷在其他适应症领域中的中枢神经系统活性,例如对裂体杀虫活性的1,4-苯二氮杂环己烷。同时还提供了制备这些化合物的方法。
