摘要

An N-phenylarylsulfonylamide compound represented by the general formula (I); an intermediate for the compound; and processes for producing these. The compound represented by the general formula (I) is bonded to a prostaglandin E2 receptor, especially an EP1 subtype receptor, to antagonize it, and has satisfactory in vivo activity because it is less affected by protein bonding. It is hence useful as an analgesic, antipyretic, remedy for frequent urination or lower urinary tract diseases, or carcinostatic substance. (I) In the formula, R<1> represents COOH, etc.; R<2> represents hydrogen, methyl, etc.; R<3> and R<4> represent a combination of methyl and methyl, etc.; R<5> represents isopropyl, etc.; Ar represents thiazolyl, pyridyl, or 5-methyl-2-furyl each optionally substituted by methyl; and n is 0 or 1.
