The invention concerns compounds having formula: ##STR1## or a salt thereof, wherein E represents hydrogen, lower alkyl or a group Ar.sup.1 --A.sup.1 ; Ar and Ar.sup.1 are the same or different aryl groups (including heteroaryl) which are optionally substituted, e.g. by one or more substituents commonly used in pharmaceutical chemistry; A and A.sup.1 are the same or different alkylene groups having one or two carbon atoms linking Ar or Ar.sup.1 to N and optionally substituted by lower alkyl and/or optionally substituted aryl, B is an alkylene group of 3 or 4 carbon atoms, which may be substituted by lower alkyl; D.sup.1 represents halogen, CH.sub.3, CR.sup.1 R.sup.2 NH.sub.2, SO.sub.3 H or SO.sub.2 NR.sup.6 R.sup.7 where R.sup.1 and R.sup.2 are independently hydrogen or lower alkyl and R.sup.6 and R.sup.7 are each hydrogen, lower alkyl or aralkyl of 7 to 12 carbon atoms or R.sup.6 and R.sup.7 together with the nitrogen atom to which they are attached represent a 5 or 6 membered ring, which compounds are useful, for treating depression or cerebral insufficiency or dementias in animals.
这项发明涉及具有以下结构的化合物:##STR1##或其盐,其中E代表氢、较低的烷基或Ar.sup.1 --A.sup.1基团;Ar和Ar.sup.1是相同或不同的芳基团(包括杂环芳基),可以选择性地被一种或多种在药物化学中常用的取代基取代,A和A.sup.1是相同或不同的烷基烃基团,其中有一个或两个碳原子将Ar或Ar.sup.1连接到N,并且可以被较低的烷基和/或可选择地被取代的芳基取代,B是一个由3或4个碳原子组成的烷基基团,可以被较低的烷基取代;D.sup.1代表卤素、CH.sub.3、CR.sup.1 R.sup.2 NH.sub.2、SO.sub.3 H或SO.sub.2 NR.sup.6 R.sup.7,其中R.sup.1和R.sup.2独立地代表氢或较低的烷基,R.sup.6和R.sup.7分别代表氢、较低的烷基或7至12个碳原子的芳基烷基或R.sup.6和R.sup.7与它们连接的氮原子一起代表一个5或6元环,这些化合物可用于治疗动物的抑郁症、脑血供不足或痴呆症。
