A 2-phenylpyridine derivative represented by the following general formula (I) or a salt thereof. The compounds have satisfactory xanthine oxidase inhibitory activity and uric acid-lowering activity and are useful as a therapeutic or preventive agent for hyperuricemia, gout, inflammatory intestinal diseases, diabetic nephropathy, diabetic retinopathy, etc. [The symbols in the formula have the following meanings: R1: H, etc.; R2: -CO2H, etc.; R3 and R4: H, etc.; R5: -CN, etc.; R6: H, etc.; X: -O-, -N(R8)-, or -S-; (provided that the groups represented by R5 and -X-R7 are bonded in a meta position or the para position to the pyridyl group) R8: H, etc.; R7: C1-8 linear or branched alkyl, etc.; Y: a bond, etc.; and R9, R10, and R11: H, etc. (provided that when X is -N(R8)-, then R8 may be bonded to R7 to form a nitrogenous saturated heterocycle in cooperation with the adjacent nitrogen atom).]

Les composés ont une activité inhibitoire d~oxydase de xanthine satisfaisante et une activité de réduction d~acide urique et servent d~agents thérapeutiques ou préventifs pour l~hyperuricémie, la goutte, les maladies intestinales inflammatoires, la néphropathie diabétique, la rétinopathie diabétique, etc. (I) [Les symboles dans la formule ont les significations suivantes : R1: H, etc.; R2: -CO2H, etc.; R3 et R4: H, etc.; R5: -CN, etc.; R6: H, etc.; X: -O-, -N(R8)-, ou -S-; (sous réserve que les groupes représentés par R5 et -X-R7 soient liés dans une méta position ou la para position avec le groupe pyridyle) R8: H, etc.; R7: un alkyle C1-8 linéaire ou ramifié, etc.; Y: une liaison, etc.; et R9, R10, and R11: H, etc. (sous réserve que si X est -N(R8)-, alors R8 peut être lié à R7 pour constituer un hétérocycle saturé azoté en coopération avec l~atome d~azote adjacent).]
