[Problem] To provide a compound that has an intestinal phosphate transporter (NPT-IIb) inhibitory action and is useful as an active ingredient of an agent for treating and/or preventing hyperphosphatemia.
[Means for Solution] The present inventors conducted thier studies on a compound that has an NPT-IIb inhibitory action and is useful as an active ingredient of an agent for treating and/or preventing hyperphosphatemia. As a result, they created an aminoalkyl-substituted N-thienylbenzamide derivative which has NPT-IIb inhibitory action, thereby completing the present invention. The aminoalkyl-substituted N-thienylbenzamide derivative of the present invention has an NPT-IIb inhibitory action and can be used as an agent for preventing and/or treating hyperphosphatemia.
[问题]提供一种化合物,该化合物具有抑制肠磷酸盐转运体(NPT-IIb)的作用,并可作为治疗和/或预防高磷酸盐血症的药物的活性成分。
[解决方法]本发明者对一种化合物进行了研究,该化合物具有 NPT-IIb 抑制作用,可作为治疗和/或预防高磷酸盐血症药物的活性成分。结果,他们创造了一种具有 NPT-IIb 抑制作用的氨基烷基取代的 N-噻吩基苯甲酰胺衍生物,从而完成了本发明。本发明的氨基烷基取代的 N-噻吩基苯甲酰胺衍生物具有 NPT-IIb 抑制作用,可用作预防和/或治疗高磷酸盐血症的药物。
