A compound represented by the formula (I)
wherein each symbol is as defined in the specification, or a salt thereof (1) shows a superior anti-ulcer activity, a gastric acid secretion-suppressive action, a mucosa-protecting action, an anti-Helicobacter pylori action and the like in living organisms, (2) shows low toxicity, (3) is stable to acid (which obviates the need to formulate an enteric-coated preparation, thereby lowering the cost, and reduces the size of preparation to facilitate swallowing for patients having difficulty in swallowing), (4) shows faster absorption than enteric-coated preparations (rapid expression of gastric acid secretion-suppressive action), and (5) is sustainable.
According to the present invention, a benzimidazole compound, which has superior stability to acid and which is converted to a proton pump inhibitor in living organisms to show an anti-ulcer activity and the like, can be provided.
由式(I)代表的化合物
其中各符号如说明书中所定义,或其盐 (1) 在生物体内显示出卓越的抗溃疡活性、胃酸分泌抑制作用、粘膜保护作用、抗幽门螺杆菌作用等;(2) 毒性低;(3) 对酸稳定(无需配制肠溶制剂、(4) 比肠溶制剂吸收更快(快速发挥抑制胃酸分泌的作用),以及 (5) 具有可持续性。
根据本发明,可以提供一种苯并咪唑化合物,该化合物对酸具有超强的稳定性,在生物体内可转化为质子泵抑制剂,从而显示出抗溃疡等活性。
