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.
提供的是公式为##STR1##的咪唑二氮平类化合物,其中R.sup.1是甲基、乙基或异丙基,R.sup.4和R.sup.5中的一个是氢,另一个是硝基或氰基,R.sup.2是氢,R.sup.3是氢或低碳基,或者R.sup.2和R.sup.3一起是二甲亚烷、三甲亚烷或丙烯亚烷,被标记为γ的碳原子具有(S)-或(R,S)-构型,X是氧或硫原子,以及它们的药学上可接受的酸盐。这些化合物在拮抗具有镇静作用的1,4-苯二氮平的中枢抑制肌肉松弛、共济失调、降低血压和呼吸抑制性质方面非常有用。它们也可以用于抑制1,4-苯二氮平在其他适应症领域中对中枢神经系统的作用,例如对血吸虫活性的1,4-苯二氮平。同时还提供了制备这些化合物的方法。
