Disclosed is a hydroquinone derivative or a pharmaceutically acceptable salt thereof, the hydroquinone derivative being represented by formula (I):
wherein
R1 is a phenyl group which is unsubstituted or substituted with a substituent or substituents each independently selected from the group consisting of a halogen atom, a C1-4 alkyl group and a C1-4 alkoxy group;
R2 is a hydrogen atom or a C1-4 alkyl group;
each of R3 and R4 is independently a hydrogen atom or a C1-4 alkyl group;
R5 is a hydrogen atom or a C1-4 alkyl group;
each of R6, R7 and R8 is independently a hydrogen atom or a C1-4 alkyl group;
P is a hydroxyl group;
Q is a hydroxyl group, a C1-4 alkoxy group, a C1-18 acyloxy group or an oxo group;
P may form together with Q an ether bond;
R is a hydroxyl group, a C1-4 alkoxy group, a C1-18 acyloxy group or an oxo group, provided that when one of said Q and said R is an oxo group, the other is also an oxo group;
X is a single bond, an -NR10- group or a -CH2-NR10- group in which R10 is a hydrogen atom or a C1-4 alkyl group;
Y is a methylene group or a carbonyl group; and
dotted bonds in a six membered ring represent that said six membered ring has the maximum number of double bonds.
