    • The quinone compound is useful to treat hepatic disease and defined by the formula:
      wherein A is a group represented by the formula:
      (wherein R 3 , R 4 and R 5 which may be the same or different from each other are each a hydrogen atom, a lower alkyl group or a lower alkoxy group) or a group represented by the formula:
      (wherein R 3 , R 4 and R 5 which may be the same or different from each other are each a hydrogen atom, a lower alkyl group or a lower alkoxy group, X and Y which may be the same or different from each other are each a hydroxyl group, a group represented by the formula
      (wherein n is 0 or 1 and R 6 is a lower alkyl group), or an acyl group),

      R 1 is an alkyl group having 2 to 20 carbon atoms, a cycloalkyl group, a cycloalkylalkyl group, an alkenyl group, an alkynyl group, an arylalkyl group, a group represented by the formula
      (wherein p is an integer of 1 to 10), a heteroarylalkyl group, a group represented by the formula
      {wherein q is an integer of 1 to 6 and B is a group represented by the formula:
      (wherein r is 0 or an integer of 1 to 2, R 7 is a lower alkyl group, a cycloalkyl group or an aryl group), or a group represented by the formula -O-R 8 (wherein R 8 is a lower alkyl group or an aryl group)}, or a group represented by the formula
      (wherein s is an integer of 1 to 3),
      R 2 is a group represented by the formula -OR 8 (wherein R 8 is a hydrogen atom or a lower alkyl group) or a group represented by the formula:
      (wherein R 9 and R 10 which may be the same of different from each other are each a hydrogen atom, a lower alkyl group, a hydroxyalkyl group or a heteroaryl group, provided that R 9 and R 10 may be combined with each other to form a ring together with a nitrogen atom bonded thereto, which may further contain a nitrogen atom and/or an oxygen atom and may be substituted).
