A naphthalene derivative having the formula is new and useful for medicine.
[wherein R1 represents a hydrogen atom, a lower alkyl group or an acyl group;
R2 independently represents a hydrogen atom, a lower alkyl group, a lower alkoxy group, a halogen atom, a cycloalkyl group, a cycloalkylalkyl group, a hydroxyl group, an aryl group which may be substituted, an arylalkyl group whose aryl group may be substituted, a heteroaryl group, or a heteroarylalkyl group;
R3 and R4 are the same or different and represent a hydrogen atom, a lower alkyl group, a lower alkenyl group, an aryl group which may be substituent, an arylalkyl group whose aryl group may be substituted, an arylalkenyl group whose aryl group may be substituted, a cycloalkyl group, an alkoxyalkyl group, a heteroaryl group, a heteroarylalkyl group, a carboxyl group, a carboxyalkyl group, an aminoalkyl group, or a cyano group;
R5 represents a group of the formula, -OR?, (wherein R represents a hydrogen atom or a lower alkyl group), or a group of the formula,
(wherein R8 and R9 are the same or different and represent a hydrogen atom or alower alkyl group or R8 and R9 can form, along with the nitrogen atom bonded with R8 and R9, a ring which may contain an oxygen atom);
R6 independently represents a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group, a hydroxyl group, an amino group, an arylalkyl group, or an aryl group; and
m is 0 or an integer of from 1 to 2, and n is 0 or an integer of from 1 to 4.]
