Claim:
A compound corresponding to formula (I) or a pharmaceutically acceptable salt or isomer thereof: wherein: A is CONH, NHCO, or NHC(═O)NH; R 1 to R 4 is independently a hydrogen, halogen atom, cyano group, nitro group, lower alkyl amine, lower alkoxy group having 1 to 3 carbon atoms, carboxylic acid, hydroxamic acid, alkyl ester group having 1 to 6 carbon atoms, alkyl amide group having 1 to 6 carbon atoms, benzylamide group, or a 5 or 6-member heterocyclic ring; R 5 and R 6 are independently a hydrogen, hydroxyl group, amino group, straight or branched alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 1 to 6 carbon atoms, or a phenyl or benzyl group optionally substituted with at least one substituent selected from the group consisting of halogen atom, an amine group, and an alkyl group having 1 to 6 carbon atoms, provided that both of R 5 and R 6 are not hydrogen atoms simultaneously; B is a group selected from in which R 7 to R 17 is independently a hydrogen atom, a halogen atom, or a straight or branched alkyl group having 1 to 6 carbon atoms optionally substituted with more than one halogen atom; C is an alkyl, alkenyl, or alkynyl group having 1 to 5 carbon atoms which may include one or more heteroatoms, wherein each of m, n, p, q, r, and s is an integer of 0 to 3; and an asteric mark * indicates a chiral carbon atom; and mark indicates a double bond or single bond chain.
