Remedies effective for the improvement of colonic motor dysfunction such as irritable bowel syndrome, constipation or intestinal atony without causing side effects on the central nerve system. These colonic motor dysfunction remedies comprise, as active ingredients, aminothiazole derivatives represented by the following formula (I) or a salt or hydrate thereof: wherein R , R and R may be the same or different and each independently represent a hydrogen atom or a hydroxyl, lower alkyl, lower alkoxy, amino, nitro or cyano group, R and R may be the same or different and each independently represent a hydrogen atom or a lower alkyl group, and n stands for an integer of from 2 to 4.
摘要:
The present invention relates to an aminothiazole derivative represented by the following formula (I): wherein R 1 , R 2 and R 3 each independently represents a hydrogen atom, a hydroxy group, a lower alkyl group, a lower alkoxy group or the like; R 4 represents a hydrogen atom or a lower alkyl group; R 5 represents a hydrogen atom, a halogen atom or a lower alkyl group; m stands for an integer of 0 to 4, A represents a substituted amino group, a substituted imino group, a heterocyclic group or the like; and B stands for an imino group or an oxygen atom, a medicament containing it and an intermediate for the preparation of said compound. The compound has strong restoration effects on dysmotility in the gastrointestinal tract and at the same time has high safety so that it is useful as an excellent gastroprokinetic.
