The invention claimed is: 1 . A compound represented by the following Chemical Formula 1 or a pharmaceutically acceptable salt of the compound: where, R 1 and R 1 ′ are each independently selected from the group consisting of hydrogen, alkyl, cycloalkyl, heterocycloalkyl, an aryl group, heteroaryl, benzyl, and a phenethyl group, or R 1 and R 1 ′ may bond to each other to form a single ring; R 2 and R 3 are each independently hydrogen, halo, cyano, alkyl, alkoxy, alkenyl, alkynyl, cycloalkyl, heterocycloalkyl, heterocycloalkyl-alkyl, aryl, aryl-alkyl, or heteroaryl; and the alkyl, alkoxy, alkenyl, alkynyl, cycloalkyl, heterocycloalkyl, heterocycloalkyl-alkyl, aryl, aryl-alkyl, or heteroaryl may not be substituted or may be substituted with one or more groups selected from the group consisting of hydroxy; halogen; alkyl; -alkyl-hydroxy; -heterocycloalkyl-alkyl-hydroxy; —NH alkyl-O-alkyl-hydroxy; —NH alkyl-O-alkyl-halogen; —NH alkyl-heterocycloalkyl; alkoxy; amino; dialkylamino; nitro; cyano; carbonyl; cycloalkyl; heterocycloalkyl unsubstituted or substituted with alkyl; aryl; and heteroaryl. 2 . The compound represented by Chemical Formula 1 or a pharmaceutically acceptable salt of the compound according to claim 1 , wherein R 1 and R 1 ′ are each independently selected from the group consisting of hydrogen, C 1 -C 6 alkyl, C 3 -C 8 cycloalkyl, C 3 -C 8 heterocycloalkyl, C 6 -C 10 aryl, C 5 -C 10 heteroaryl, benzyl and a phenethyl group, or R 1 and R 1 ′ may bond to each other to form a single ring. 3 . The compound represented by Chemical Formula 1 or a pharmaceutically acceptable salt of the compound according to claim 1 , wherein 4 . The compound represented by Chemical Formula 1 or a pharmaceutically acceptable salt of the compound according to claim 1 , wherein R 2 is hydrogen; C 1 -C 12 alkyl unsubstituted or substituted with halogen; C 3 -C 10 cycloalkyl; —C 1 -C 6 alkyl-C 3 -C 10 heterocycloalkyl containing one or more heteroatoms selected from the group consisting of N, S and O; —C 6 -C 10 aryl unsubstituted or substituted with halogen or C 1 -C 12 alkyl; or —C 1 -C 6 alkyl-C 6 -C 10 aryl. 5 . The compound represented by Chemical Formula 1 or a pharmaceutically acceptable salt of the compound according to claim 1 , wherein R 2 is hydrogen; C 1 -C 12 alkyl; C 1 -C 6 alkyl substituted with halogen; C 3 -C 8 cycloalkyl; —C 1 -C 6 alkyl-C 3 -C 10 heterocycloalkyl containing heteroatoms N and O; —C 6 -C 10 aryl unsubstituted or substituted with halogen or C 1 -C 6 alkyl; or —C 1 -C 6 alkyl-C 6 -C 10 aryl. 6 . The compound represented by Chemical Formula 1 or a pharmaceutically acceptable salt of the compound according to claim 1 , wherein R 2 is hydrogen; C 1 -C 12 alkyl; C 1 -C 6 alkyl substituted with halogen; C 3 -C 8 cycloalkyl; —C 1 -C 6 alkyl-morpholine; phenyl unsubstituted or substituted with halogen or C 1 -C 6 alkyl; or —C 1 -C 6 alkyl-phenyl. 7 . The compound represented by Chemical Formula 1 or a pharmaceutically acceptable salt of the compound according to claim 1 , wherein R 3 is C 6 -C 10 heterocycloalkyl, C 6 -C 10 aryl or C 6 -C 10 heteroaryl, and the heterocycloalkyl, aryl or heteroaryl is not substituted or is substituted with one or more groups selected from the group consisting of hydroxy; halogen; C 1 -C 6 alkyl; —C 1 -C 6 alkyl-hydroxy; —C 3 -C 8 heterocycloalkyl-C 1 -C 6 alkyl-hydroxy; —NHC 1 -C 6 alkyl-O—C 1 -C 6 alkyl-hydroxy; —NHC 1 -C 6 alkyl-O—C 1 -C 6 alkyl-halogen; —NHC 1 -C 6 alkyl-C 3 -C 8 heterocycloalkyl; C 1 -C 6 alkoxy; amino; di-C 1 -C 6 alkylamino; and C 3 -C 8 heterocycloalkyl unsubstituted or substituted with C 1 -C 6 alkyl. 8 .
