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 or nitro, R.sup.4 is hydrogen, trifluoromethyl or halogen, R.sup.5 is hydrogen, fluoromethyl, halogen or lower alkyl and X is an oxygen or sulphur atom, and either R.sup.2 is hydrogen and R.sup.3 is lower alkyl or R.sup.2 and R.sup.3 together are trimethylene or propenylene and the carbon atom denoted as .gamma. has the (S)-- or (R,S)-- configuration, and their pharmaceutically acceptable acid addition salts. The compounds antagonize the central-depressant, muscle relaxant, ataxic, blood pressure-lowering and respiratory-depressant properties of 1,4-benzodiazepines which have tranquillizing activity. Thus they can be used, for example, as antidotes in the case of intoxications with 1,4-benzodiazepines which have tranquillizing activity. Also presented are various methods to produce the imidazodiazepine derivatives.
提供了公式为##STR1##的
咪唑二氮平类化合物,其中A与标记为α和β的两个碳原子一起是##STR2##,R.sup.1是氢、低烷基、低烷氧甲基、卤素或硝基,R.sup.4是氢、三
氟甲基或卤素,R.sup.5是氢、
氟甲基、卤素或低烷基,X是氧或
硫原子,R.sup.2要么是氢,R.sup.3是低烷基,要么R.sup.2和R.sup.3一起是三亚甲基或
丙烯亚甲基,标记为γ的碳原子具有(S)-或(R,S)-构型,并且它们的药学上可接受的酸盐也被提供。这些化合物对具有镇静活性的1,4-苯二氮平的中枢抑制、肌肉松弛、共济失调、降压和呼吸抑制特性具有拮抗作用。因此,它们可以用作例如在1,4-苯二氮平有镇静作用的中毒情况下的解毒剂。还提供了各种制备
