PROBLEM TO BE SOLVED: To provide novel compounds having EDG (endothelial differentiation gene) receptor antagonism which are useful as active components of drugs for preventing and/or treating inflammatory diseases or the like.
SOLUTION: The compounds are represented by formula (I) (wherein R1is hydrogen or an alkyl group; R2is hydrogen present at any substitutable position on ring C or a substituent such as a hydroxy group, a carboxy group, and a nitro group; R3is hydrogen present at any substitutable position on ring D or a substitutent such as a hydroxy group and an aralkyloxy group; X is an alkylamino group, an amino group or the like; Y is a carboxy group, a sulfo group or a phosphono group; Z is oxygen, sulfur or the like; a ring represented by A is a 5- or 6-membered saturated or unsaturated hydrocarbon ring; and a ring represented by B is a 4- or 7-membered saturated or unsaturated hydrocarbon ring containing one -C=C- as a partial structure shown in the above formula) and include their salts and their esters.
