Carboxylic acid derivatives represented by the following general formula (I) and nontoxic salts thereof: (I) wherein R1 represents COOH, COOR4 (wherein R4 represents alkyl, etc.), etc.; A represents alkylene, etc.; R2 represents alkyl, etc.; m is 0, etc.; B represents a benzene ring, etc.; Q represents an alkylene-Cyc 2 (wherein Cyc 2 represents a heterocycle, etc.), an alkylene-o- benzene ring, etc.; D represents O-alkylene, NHCO-alkylene, etc.; and R3 represents a benzene ring, a naphthalene ring, etc. Because of binding to PEG2 receptors, in particular, subtype EP3 and/or subtype EP4 and having antagonism, the compounds represented by the general formula (I) are useful in preventing and/or treating diseases such as pain.

Cette invention se rapporte à des dérivés d'acide carboxylique, représentés par la formule générale (I), et à des sels non toxiques de ces dérivés. Dans ladite formule, R?1¿ représente COOH, COOR?4¿ (où R?4¿ représente alkyle, etc.), etc.; A représente alkylène, etc.; R?2¿ représente alkyle, etc.; m est égal à 0, etc.; B représente un cycle benzène, etc.; Q représente alkylène-Cyc 2 (où Cyc 2 représente un hétérocycle, etc.), un cycle alkylène-o-benzène, etc.; D représente O-alkylène, NHCO-alkylène, etc.; et R?3¿ représente un cycle benzène, un cycle naphtalène, etc. Grâce à leur capacité de fixation des récepteurs PEG2, notamment le sous-type EP3 et/ou le sous-type EP4, et grâce à leurs propriétés antagonistes, les composés représentés par la formule générale (I) sont utiles pour prévenir et/ou traiter les maladies telles que la douleur.
