There is presented imidazodiazepines of the formula ##STR1## wherein A together with the two carbon atoms denoted as .alpha. and .beta. is the group ##STR2## R.sup.1 is hydrogen, lower alkyl, lower alkoxymethyl, halogen, nitro or a group of the formula --COOR.sup.4,R.sup.2 is hydrogen, trifluoromethyl or halogen, R.sup.3 is hydrogen, trifluoromethyl, halogen or lower alkyl, R.sup.4 is methyl, ethyl or isopropyl and X is an oxygen or sulphur atom and the carbon atom denoted as .gamma. has the (S)- or (R,S)-configuration, 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 therapy, for example, of schistosomicidally-active 1,4-benzodiazepines. Also provided are methods to produce the above compounds.
提供了式子为##STR1##的
咪唑二氮平类化合物,其中A与表示为.alpha.和.beta.的两个碳原子一起是##STR2##,R.sup.1是氢、低碳基、低氧甲基、卤素、硝基或式子--COOR.sup.4的基团,R.sup.2是氢、三
氟甲基或卤素,R.sup.3是氢、三
氟甲基、卤素或低碳基,R.sup.4是甲基、乙基或异丙基,X是氧或
硫原子,表示为.gamma.的碳原子具有(S)-或(R,S)-构型,以及其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
抑制剂、肌肉松弛剂、共济失调、降压和呼吸抑制性质方面有用。它们还可用于抑制在其他治疗领域中使用的1,4-苯二氮平对中枢神经系统的活性,例如对血吸虫活性的1,4-苯二氮平。还提供了制备上述化合物的方法。
