Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a new sulfonamide derivative useful as an active component for prostaglandin E2 antagonistic or agonistic agent. SOLUTION: The objective compound is expressed by formula I [a group of formula II is a 5 to 7-membered heterocyclic group having a 5-7C carbon ring, O, S and N; Z1 is COR1 (R1 is OH or the like) or the like; Z2 is a 1-8C alkyl, a 2-8C alkenyl or the like; Z3 is single bond or a 1-4C alkylene; Z4 is SO2; Z5 is a 1-8C alkyl, phenyl or the like; R2 is CONR8 (R8 is H or a 1-4C alkyl), NR8CO or the like; R3 is a 1-6C alkyl, a halogen or the like; R4 is a 1-8C alkyl or the like; (n) is 1-4], e.g. 5-[5-chloro-2-(phenylsulfonylamino)phenoxy] pentaonic acid. The compound of formula I wherein Z1 is e.g. COOH can be produced by the hydrolysis of an ester compound of formula III [Z1b is COR1b (R1b is a 1-4C alkoxy or the like); R3b is R3; R4b is R4; Z5b is Z5, provided that Z5b is COOH or OH protected with an eliminable protecting group when R5 is COOH, OH or the like]. |
