The present invention relates to Compounds represented by the formula (I) or salts thereof. In the formula (I), the ring A represents a benzene ring, a thiophene ring, or a pyridine ring; R a represents a hydrogen atom, a halogen atom, an alkyl group, or an alkoxy group; the ring B represents a pyridine ring, a pyrimidine ring, or a quinoline ring; the ring C represents a benzene ring, a pyridine ring, a quinoline ring, or an isoquinoline ring; X and Y, the same or different, represent an oxygen atom or a sulfur atom, with the proviso that the case X is a sulfur atom and Y is an oxygen atom be excluded; R 1 represents a hydrogen atom, a halogen atom, an amino group, a cycloalkylamino group, an alkylcarbonylamino group, an alkyloxycarbonylamino group, an alkylaminocarbonyl group, or a non-aromatic heterocyclic group; and R 2 and R 2 ', the same or different, represent a hydrogen atom, a halogen atom, an alkyl group, a halogeno-alkyl group, or a halogeno-alkoxy group.
