1. A compound represented by the formula (I):
![]() R2 and R3 are taken together with the adjacent carbon atom to form an optionally substituted 5 to 8 membered non-aromatic carbocyclic
ring or an optionally substituted 5 to 8 membered non-aromatic heterocyclic ring;
R4 is C1-C6 alkyl, hydroxyC1-C6alkyl, optionally substituted aminoC1-C6alkyl, or C1-C6 alkoxyC1-C6 alkyl;
X is an oxygen atom or a sulfur atom;
A is a group of the formula:
![]() W is —CH2CH2CH2—, —CH2CH2CH2CH2—, —OCH2O—, —OCH2CH2O—, —N(CH3)CH2CH2CH2—, or —CH═CH—CH═CH—;
n is an integer of 0 to 7;
