[1,2]-fused 1,4-benzodiazepine compounds are disclosed corresponding to the general formula I ##STR1## wherein X is an oxygen or sulfur atom or an optionally substituted imino group, R.sub.1 is a hydrogen or halogen atom, lower alkyl radical, a lower alkoxy radical or a nitro group and R.sub.2 is a hydrogen or halogen atom, a lower alkyl radical, a lower alkoxy radical or a nitro group, or if R.sub.1 is a hydrogen atom, R.sub.2 may also be a lower alkylthio radical, or, if R.sub.1 is a hydrogen atom and X is a sulfur atom or an imino group, R.sub.2 may be a trifluoromethyl radical; or R.sub.1 and R.sub.2 are bonded to adjacent carbon atoms and together denote a methylenedioxy or ethylenedioxy radical; R.sub.3 is an optionally substituted furyl, thienyl, pyrrolyl or pyridyl radical and n is zero or, if R.sub.3 is furyl or thienyl, n may be 0 or 1. The compounds may be in the form of their optical isomers or acid addition salts. The compounds exhibit neuroleptic properties. Processes for preparing the compounds and pharmaceutical compositions containing them are also disclosed.
公开了与通式I相对应的[1,2]-融合的1,4-苯二氮平类化合物,其中X是氧或硫原子或可选取代的亚胺基团,R1是氢或卤素原子,较低的烷基基团,较低的烷氧基团或硝基基团,而R2是氢或卤素原子,较低的烷基基团,较低的烷氧基团或硝基基团,或者如果R1是氢原子,则R2也可以是较低的烷硫基团,或者如果R1是氢原子且X是硫原子或亚胺基团,则R2可以是三氟甲基基团;或者R1和R2与相邻的碳原子结合并一起表示甲二氧基或乙二氧基基团;R3是可选取代的呋喃基,噻吩基,吡咯基或吡啶基团,n为零或者如果R3是呋喃基或噻吩基,则n可以为0或1。这些化合物可以是其光学异构体或酸加成盐的形式。这些化合物表现出神经元抑制特性。还公开了制备这些化合物和含有它们的制药组合物的方法。
