This invention is concerned with 1,4-dioxino[2,3-b]-pyridine derivatives having formula I
wherein each of the groups R is independently selected from hydrogen, hydroxy, lower alkyl, lower alkoxy, CF₃, and halogen;
R₁ is hydrogen or lower alkyl;
n is 2, 3, or 4;
X is CH₂, C=O, or SO₂; and
Y is substituted or unsubstituted 1,2-phenylene, -(CH₂)₄-, -CH₂CR₂R₃-, or -CH₂CR₂R₃CH₂-, in which R₂ and R₃ are independently hydrogen or lower alkyl, or together 1,4-butanediyl or 1,5-pentanediyl; or pharmaceutically acceptable salts thereof.
The compounds according to the invention are strong serotonin ligands with preference for the 5HT1A receptor and may, therefore, find application as anti-depressants or as a drug in combating anxiety disorders.
本发明涉及具有式I的1,4-二氧杂[2,3-b]-吡啶衍生物,其中R的每个基团独立地选自氢、羟基、低级烷基、低级烷氧基、CF₃和卤素;R₁为氢或低级烷基;n为2、3或4;X为CH₂、C=O或SO₂;Y为取代或未取代的1,2-苯撑基、-(CH₂)₄-、-CH₂CR₂R₃-或-CH₂CR₂R₃CH₂-,其中R₂和R₃独立地为氢或低级烷基,或一起为1,4-丁二基或1,5-戊二基;或其药学上可接受的盐。本发明中的化合物是强的5-羟色胺配体,具有对5HT1A受体的选择性,因此可以作为抗抑郁剂或用于对抗焦虑症的药物。
