1. A maleic acid derivative represented by Chemical Formula 1 below or a pharmaceutically acceptable salt thereof: wherein, A is 5- to 7-membered phenyl having a substituent group, or heteroaryl or heterocycloalkyl containing at least one heteroatom selected from the group consisting of N, O, and S and having a substituent group, or 5- to 7-membered phenyl, heteroaryl, or heterocycloalkyl linked to C1-C5 straight- or branched-chain alkyl, wherein the substituent group is unsubstituted, halogen, OH, OR1, nitro, nitrile, NH2, NHR1, NR1R2 COOH, COOR1, CONH2, CONHR1, C1-C5 straight- or branched-chain alkyl, phenyl, heteroaryl, or 5- to 7-membered heterocycloalkyl, where R1 and R2 each are C1-C5 straight- or branched-chain alkyl, or phenyl or heteroaryl having a substituent group; when R is OH, the phenyl having a substituent group is excluded from A, wherein the substituent group is unsubstituted, halogen, OH, OR1, nitro, nitrile, NH2, NHR1, NR1R2 COOH, COOR1, CONH2, CONHR1, C1-C5 straight- or branched-chain alkyl, phenyl, heteroaryl, or 5- to 7-membered heterocycloalkyl, where R1 and R2 each are C1-C5 straight- or branched-chain alkyl or phenyl or heteroaryl having a substituent group; and R is OH, OR1, NH2, NHR1, NR1R2, 5- to 7-membered phenyl having a substituent group, or heteroaryl or heterocycloalkyl containing at least one heteroatom selected from the group consisting of N, O, and S and having a substituent group, wherein the substituent group is unsubstituted, halogen, OH, OR1, nitro, nitrile, NH2, NHR1, NR1R2 COOH, COOR1, CONH2, CONHR1, C1-C5 straight- or branched-chain alkyl, phenyl, heteroaryl, or 5- to 7-membered heterocycloalkyl, where R1 and R2 each are C1-C5 straight- or branched-chain alkyl or phenyl. |
