ABSTRACT:
Objects of the present invention are to study on the synthesis of a novel pyrrole derivative having a ureido group and an aminocarbonyl group as substituents or a salt thereof, to find a pharmacological effect of the derivative or a salt thereof, and to find a medicinal agent which has a prophylactic and/or therapeutic effect on a retinal disease or the like through oral administration. A compound represented by the general formula (1) or a salt thereof has an inhibitory activity against the production of interleukin-6 and/or an inhibitory effect on choroidal neovascularization, and is therefore useful as a prophylactic and/or therapeutic agent for a disease associated with interleukin-6, an ocular inflammatory disease and/or a retinal disease. In the formula, the ring A represents a benzene ring or the like; R1represents a halogen atom, a hydrogen atom, a lower alkyl group or the like; R2represents a halogen atom, a lower alkyl group which may have a substituent, a lower alkenyl group, a lower alkynyl group which may have a substituent, a lower cycloalkyl group, an aryl group, a hydroxy group, a lower alkoxy group which may have a substituent or the like; and n represents 0, 1, 2, 3 or the like.
