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 substituents 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.
本发明揭示了以氨基(较低)烷基基团连接到吡喃并[3,4-b]吲哚或硫代吡喃并[3,4-b]吲哚核的1和9位置中的一个或两个位置,或者连接到吡喃并[4,3-b]吲哚或硫代吡喃并[4,3-b]吲哚核的1位置的吡喃并吲哚或硫代吡喃并吲哚衍生物。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中。在位置1处仅具有氨基(较低)烷基基团的衍生物在位置1处进一步取代,并且可以选择地在位置3,4,5,6,7,8和9处取代。在位置9处仅具有氨基(较低)烷基基团的吡喃并[3,4-b]吲哚或硫代吡喃并[3,4-b]吲哚衍生物在位置1处具有两个取代基,并且可以选择地在位置3,4,5,6,7和8处取代;在位置1和9处均具有氨基(较低)烷基基团的衍生物在位置1处进一步取代,并且可以选择地在位置3,4,5,6,7和8处取代。本发明的吡喃并吲哚和硫代吡喃并吲哚衍生物是有用的抗抑郁和抗溃疡剂。还公开了这些衍生物的制备和使用方法。
