The present invention relates to novel imidazo[2,1-b]benzothiazole compounds represented by formula (I) and pharmacological acceptable salts thereof:
wherein R₁ represents a hydrogen atom or a lower alkyl group having 1 to 4 carbon atoms; R₂ represents a
group (wherein X and Y, which may be the same or different, each represents a hydrogen atom, a lower alkyl group having 1 to 4 carbon atoms or a substituted or unsubstituted phenyl group), a -CH₂-O-Z group (wherein Z represents a lower alkyl group having 1 to 4 carbon atoms or a substituted or unsubstituted benzyl group) or a -CH₂-O-CO-W group (wherein W represents an alkyl group having 1 to 8 carbon atoms, an alkylamino group having 1 to 8 carbon atoms, a substituted or unsubstituted phenyl group or a thienyl group); and R₃, R₄ and R₅, which may be the same or different, each represents a hydrogen atom, a halogen atom or a lower alkoxy group having 1 to 4 carbon atoms and antiulcer compositions comprising as the effective ingredient the compounds.
本发明涉及式(I)代表的新型咪唑并[2,1-b]苯并噻唑化合物及其药理学上可接受的盐:
其中 R₁ 代表氢原子或具有 1 至 4 个碳原子的低级烷基; R₂ 代表
基团(其中 X 和 Y 可以相同或不同,各自代表氢原子、具有 1 至 4 个碳原子的低级烷基或取代或未取代的苯基)、-CH₂-O-Z-基团(其中 Z 代表具有 1 至 4 个碳原子的低级烷基或取代或未取代的苄基)或-CH₂-O-CO-W-基团(其中 W 代表具有 1 至 8 个碳原子的烷基、具有 1 至 8 个碳原子的烷基氨基、取代或未取代的苯基或噻吩基);和 R₃、R₄ 和 R₅,它们可以相同或不同,各自代表氢原子、卤素原子或具有 1 至 4 个碳原子的低级烷氧基,以及包含这些化合物作为有效成分的抗溃疡组合物。
