Provided are 1-N-aminobenzimidazole derivatives represented by the following formula (I):
wherein R1 and R2 each represents a substituted or unsubstituted alkyl group or the like, R3, R5 and R6 each represents an alkyl group, alkoxy group, hydrogen atom or the like, R4 represents a substituted or unsubstituted alkyl group or the like, A represents a benzene ring or the like, B represents a hydrogen atom or the like, an n stands for an integer of from 0 to 2, or salts thereof; and medicines containing them.
The compounds (I) according to the present invention do not bring about much individual differences in therapeutic effects despite the existence of individual differences in the CYP2C19 activity. At the same dose, they can hence bring about appropriate therapeutic effects for all patients. In addition, they are low in the risk of induction of an interaction or a cancer caused by induction of the CYP1A family. Accordingly, they are useful as peptic ulcer therapeutic agents which are safe and surely bring about therapeutic effects.
提供的是以下公式(I)所代表的1-N-氨基苯并咪唑衍生物,其中R1和R2分别代表取代或未取代的烷基基团或类似物,R3、R5和R6分别代表烷基基团、烷氧基、氢原子或类似物,R4代表取代或未取代的烷基基团或类似物,A代表苯环或类似物,B代表氢原子或类似物,n表示0到2的整数,或其盐;以及含有它们的药物。根据本发明的化合物(I)尽管CYP2C19活性存在个体差异,但在治疗效果上并不会带来太大的个体差异。在相同剂量下,它们可以为所有患者带来适当的治疗效果。此外,它们在诱导CYP1A家族引起相互作用或癌症的风险较低。因此,它们作为对消化性溃疡有用的治疗剂,既安全又确实能带来治疗效果。
