2,5,6,7-tetrasubstituted Thiazolo[4,5-b]pyridine Derivatives and Use Thereof

A 2,5,6,7-tetrasubstituted thiazolo[4,5-b]pyridine derivative represented by Formula 1 and a pharmaceutically available salt thereof,

• where R1 is a five to seven-membered substituted or unsubstituted aromatic group to which carbon, oxygen, nitrogen or sulfur is added, in which the aromatic group is a heteroaryl group, a phenyl group or a substituted phenyl group, here, the substituent is one to four substituents selected from the group consisting of hydrogen, halogen, cyano, nitro, hydroxy, C1˜C10 linear or branched alkyl, C1˜C10 alkoxy, C1˜C10 haloalkyl, C1˜C10 haloalkoxy, C1˜C10 alkylthio, C1˜C10 alkyl carbonyl and a C1˜C10 alkoxy carbonyl group,
• R2 and R3 are hydrogen, a C1˜C10 linear, branched or cyclic alkyl group, a cyclic C1˜C10 alkyl group including a heteroelement (—NH—, —S—, —O—) or heteroalkyl group, or a C1˜C10 linear or branched carbonyl group, which are independently or identically substituted, and
• R4 is an amino group substituted by one or at least two C1˜C10 linear, branched or cyclic alkyl groups, C5˜C10 aryl groups, C5˜C10 heteroaryl groups or substituted heteroaryl groups, C5˜C10 arylalkyl groups, a benzyl group, a substituted benzyl group or C5˜C10 heteroarylalkyl groups, or a phenyl group, a substituted phenyl group, a benzyl group, a substituted benzyl group, a C1˜C10 linear, branched or cyclic alkyl group, or an amine group having a piperazine
• substituted by phenyl or a heteroarylamide group, or C3˜C10 cyclic amine groups, or C3˜C10 cylclic amine groups containing at least one heteroatom selected from the group consisting of N, O, and S, here, the substituent is one to three substituents selected from the group consisting of a halogen atom, a nitro group, a C1˜C10 alkyl group, a C1˜C10 alkoxy group, a C1˜C10 haloalkyl group and a C1˜C10 haloalkoxy group.
