Provided is a compound which is useful as a therapeutic agent for chronic renal insufficiency and a therapeutic agent for diabetic nephropathy.
The present inventors have made extensive studies on an ornithine derivative having an antagonistic action against an EP4 receptor, and as a result, they have found that by introducing cycloalkanediyl at a C terminal of the ornithine part of the compound of the present invention, the physicochemical properties such as solubility, and the like can be improved, thereby giving further preferred properties as a pharmaceutical. Therefore, they have completed the present invention.
The compound of the present invention exhibits a good antagonistic action against an EP4 receptor, and thus, it is useful as a therapeutic agent for chronic renal insufficiency and diabetic nephropathy.
提供了一种化合物,可用作慢性肾功能不全的治疗剂和糖尿病肾病的治疗剂。目前的发明人对具有对EP4受体拮抗作用的鸟氨酸衍生物进行了广泛研究,结果发现通过在目前发明的化合物的鸟氨酸部分的C末端引入环烷基,可以改善物理化学性质,如溶解性等,从而赋予其作为药物的更优越性质。因此,他们完成了这项发明。目前发明的化合物对EP4受体表现出良好的拮抗作用,因此,它可用作慢性肾功能不全和糖尿病肾病的治疗剂。
