Pyranoindole and thiopyranoindole derivatives characterized by having an amino(lower)alkyl radical attached to either or both the 1 and 9 position of a pyrano[3,4-b]indole or thiopyrano[3,4-b]indole nucleus or having said radical attached to the 1 position of a pyrano[4,3-b]indole or thiopyrano[4,3-b]indole nucleus are disclosed. The amino portion of the amino(lower)alkyl radical may be further substituted with one or two lower alkyl groups or incorporated into a heterocyclic amine radical. The derivatives having the amino(lower)alkyl radical only at position 1 are further substituted at position 1 and may be optionally substituted at positions 3,4,5,6,7,8, and 9. The pyrano[3,4-b]indole or thiopyrano[3,4-b]indole derivatives having the amino(lower)alkyl radical only at position 9 possess two substitutents at position 1 and may be optionally substituted at position 3,4,5,6,7, and 8; the derivatives having an amino(lower)alkyl radical at both positions 1 and 9 are further substituted at position 1 and may be optionally substituted at positions 3,4,5,6,7 and 8. The pyrano-and thiopyranoindole derivatives of this invention are useful antidepressant and antiulcer agents. Methods for the preparation and use of these derivatives are also disclosed.
Pyranoindole和thiopyranoindole衍生物的特征在于在pyrano[3,4-b]indole或thiopyrano[3,4-b]indole核的1和9位置之一或两者上附加有氨基(较低)烷基基团,或者在pyrano[4,3-b]indole或thiopyrano[4,3-b]indole核的1位置上附加有该基团。氨基(较低)烷基基团的氨基部分可能进一步被一个或两个较低烷基基团取代,或者被并入一个杂环胺基团。只在位置1具有氨基(较低)烷基基团的衍生物在位置1进一步被取代,并且可以选择在位置3,4,5,6,7,8和9处被取代。只在位置9具有氨基(较低)烷基基团的pyrano[3,4-b]indole或thiopyrano[3,4-b]indole衍生物在位置1处具有两个取代基,并且可以选择在位置3,4,5,6,7和8处被取代;在位置1和9处都具有氨基(较低)烷基基团的衍生物在位置1处进一步被取代,并且可以选择在位置3,4,5,6,7和8处被取代。本发明的pyrano和thiopyranoindole衍生物可用作抗抑郁和抗溃疡剂。还公开了这些衍生物的制备和使用方法。
