The present invention relates to imidazo[2,1-b]thiazole compounds represented by formula (I) and pharmacologically acceptable salts thereof:
wherein R₁ and R₂ may be the same or different groups and each represents a hydrogen atom or a lower alkyl group having 1 to 6 carbon atoms; R₃ represents a hydrogen atom, a lower alkyl group having 1 to 6 carbon atoms or a phenyl group which may be optionally substituted by methyl group, methoxy group or halogen; and R₄ represents a hydrogen atom or a lower alkyl group having 1 to 3 carbon atoms, with the proviso that when R₃ represents a hydrogen atom, at least one of R₁ and R₂ represents a lower alkyl group having 1 to 6 carbon atoms, and antiulcer agents comprising said compounds or salts thereof as the active ingredient.
本发明涉及由式(I)表示的咪唑并[2,1-b]噻唑化合物及其药学上可接受的盐:其中R₁和R₂可以是相同或不同的基团,每个基团表示氢原子或具有1到6个碳原子的低烷基基团;R₃表示氢原子,具有1到6个碳原子的低烷基基团或苯基,该苯基可以选择性地被甲基基团,甲氧基或卤素取代;R₄表示氢原子或具有1到3个碳原子的低烷基基团,但当R₃表示氢原子时,至少有一个R₁和R₂表示具有1到6个碳原子的低烷基基团,以所述化合物或其盐作为活性成分的抗溃疡剂。
