Thienopyridine derivatives and pharmaceutical composition comprising same

A compound represented by the following Formula 1, or a pharmaceutically acceptable salt thereof:

• wherein
• R1 and R2 are each independently H, halogen, C1-10 alkoxy, or halo C1-10 alkyl;
• X is —C(—R3)═ or —N═;
• R3 and R4 are each independently H, halogen, C1-10 alkyl, or C1-10 alkoxy;
• R5 is H, halogen, or C1-10 alkyl;
• and
• R6 and R7 are each independently H, C1-10 alkyl, or —(CH2)n—Y—R8, or R6 and R7, taken together with the N atom to which they are bonded, form a 4- to 10-membered heterocycle,
• wherein n is an integer of 0 to 10;
• Y is —O—, —C(═O)—, —C(═O)—O—, —S—, or —S(═O)2—;
• R8 is a linear or branched C1-10 alkyl, wherein R8 is unsubstituted or substituted with one or more substituents selected from the group consisting of halogen, amino, hydroxyl and C1-6 alkoxy;
• and
• said heterocycle optionally further contain one or two heteroatoms selected from the group consisting of N, O, and S, in addition to the N atom to which R6 and R7 are bonded, and is unsubstituted or substituted with one or more substituents selected from halogen and C1-6 alkyl.
