The invention concerns compounds having formula:
or a salt thereof, wherein E represents hydrogen, lower alkyl or a group Ar¹-A¹-; Ar and Ar¹ are the same or different aryl groups (including heteroaryl) which are optionally substituted, eg by one or more substituents commonly used in pharmaceutical chemistry; A and A¹ are the same or different alkylene groups having one or two carbon atoms linking Ar or Ar¹ 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; D¹ represents halogen, CH₃, CR¹R²NH₂, SO₃H or SO₂NR⁶R⁷ where R¹ and R² are independently hydrogen or lower alkyl and R⁶ and R⁷ are each hydrogen, lower alkyl or aralkyl of 7 to 12 carbon atoms or R⁶ and R⁷ togehter 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.
本发明涉及具有以下式子的化合物
或其盐,其中 E 代表氢、低级烷基或基团 Ar¹-A¹-;Ar 和 Ar¹ 是相同或不同的芳基(包括杂芳基),它们被任选取代,例如被药物化学中常用的一个或多个取代基取代;A 和 A¹ 是相同或不同的亚烷基,它们具有一个或两个碳原子,将 Ar 或 Ar¹ 与 N 连接,并任选被低级烷基和/或任选取代的芳基取代,B 是具有 3 或 4 个碳原子的亚烷基,可被低级烷基取代;D¹ 代表卤素、CH₃、CR¹R²NH₂、SO₃H 或 SO₂NR⁶R⁷,其中 R¹ 和 R² 独立地为氢或低级烷基,R⁶ 和 R⁷ 各自为氢、R⁶和 R⁷ 与它们所连接的氮原子一起代表一个 5 或 6 个成员的环,这些化合物可用于治疗动物的抑郁症、脑功能不全或痴呆症。
