    摘要: The present invention relates to an agent for the prevention or treatment of a renal disease comprising as an active ingredient a 5-amidino-2-hydroxybenzenesulfonamide derivative represented by the general formula:
    wherein R 1 is a hydrogen atom or an optionally substituted alkyl group;
    R 2 is a dialkylamino group, an alkyl group, a cycloalkyl group, an optionally substituted aryl group etc.;
    T is an oxygen atom, a sulfur atom etc.;
    Q is a hydrogen atom or an optionally substituted alkyl group;
    and Z is a hydrogen atom, a hydroxy group etc.,
    or a pharmaceutically acceptable salt thereof which has an inhibitory effect on mesangial cell proliferation and a decreasing effect on protein excretion in urine, and are useful for preventing or treating of various renal diseases such as IgA nephropathy, diabetic nephropathy, nephritic syndrome and the like.
