Abstract:
Compounds having an 8-azaprostaglandin skeleton represented by the following general formula (I): (I) wherein each symbol is as defined in the description; salts thereof, solvates thereof, clathrate compounds thereof in cyclodextrin, prodrugs thereof and drugs containing the same as the active ingredient have an EP4 agonism and, therefore, are useful in preventing and/or treating diseases such as immune diseases, asthma, nerve cell death, arthritis, pulmonary injury, pulmonary fibrosis, pulmonary emphysema, bronchitis, chronic obstructive pulmonary disease, liver injury, acute hepatitis, nephritis, renal failure, hypertension, myocardial ischemia, systemic inflammatory reaction syndrome, sepsis, hemophagous syndrome, macrophage activation syndrome, Steele's disease, Kawasaki's disease, burn, systemic granuloma, ulcerative colitis, Crohn's disease, hypercytokinemia in dialysis, multiorgan failure, shock and glaucoma. Because of having an effect of promoting osteogenesis, moreover, they are useful in preventing and/or treating diseases with bone loss (bone diseases such as primary osteoporosis, secondary osteoporosis, bone metastasis of cancer, hypercalcemia, Behcet's disease, bone defect and bone necrosis, postoperative osteogenesis, alternative therapy for bone transplantation).
Abstract:
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 represents COOH, etc.; R represents hydrogen, methyl, etc.; R and R represent a combination of methyl and methyl, etc.; R represents isopropyl, etc.; Ar represents thiazolyl, pyridyl, or 5-methyl-2-furyl each optionally substituted by methyl; and n is 0 or 1.
