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; R1 represents a halogen atom, a hydrogen atom, a lower alkyl group or the like; R2 represents 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.
本发明的目的是研究合成一种新的吡咯衍生物,其具有尿素基团和氨基羰基团作为取代基或其盐,寻找该衍生物或其盐的药理作用,并通过口服寻找具有预防和/或治疗视网膜疾病或类似疾病的药物。通式(1)表示的化合物或其盐具有抑制白细胞介素-6的产生和/或对脉络膜新生血管的抑制作用,因此可用作预防和/或治疗与白细胞介素-6相关的疾病、眼部炎症性疾病和/或视网膜疾病的药物。在该式中,环A表示苯环或类似物;R1表示卤素原子、氢原子、低碳基或类似物;R2表示卤素原子、可能具有取代基的低碳基、低烯基基团、可能具有取代基的低炔基基团、低环烷基、芳基、羟基、可能具有取代基的低烷氧基或类似物;n表示0、1、2、3或类似物。
