Claims14
A heteroaryl compound having a structure of formula (I), or a pharmaceutically acceptable salt, a solvate, a hydrate, an isotopically labeled derivative or a radiolabeled derivative thereof,
- wherein,
- Ra is selected from the group consisting of
- H, OH, halogen, C1-3 alkyl, C1-3 alkoxy, NH2, C1-3 alkylamino and C1-6 alkoxycarbonyl, wherein said C1-3 alkyl, said C1-3 alkoxy, said C1-3 alkylamino, and said C1-6 alkoxycarbonyl are optionally substituted with OH, halogen, C2-6 heterocycloalkyloxy or toluenesulfonyloxy;
- Q is CH or N;
- X is CH and Y is N, or X is N and Y is CR6;
- R6 is selected from the group consisting of H, NH2 and C1-6 alkoxy;
- wherein said NH2 is optionally substituted with C1-3 alkyl, and said C1-6 alkoxy is optionally substituted with C1-3 alkyl or halogen;
- J is CH or N;
- K is CH or N;
- and
- provided that J and Y are not N simultaneously;
- R′ is halogen, OH, C1-6 alkyl, or C1-6 alkoxy;
- R″ is Br, I, OH, NH2,
- C1-6 alkylamino or C3-6 heterocycloalkyl;
- wherein said C1-6 alkylamino and said C3-6 heterocycloalkyl are optionally substituted with a substituent selected from the group consisting of oxo, OH, halogen, C3-6 cycloalkyl, C1-4 alkoxy carbonyl, C3-6 heterocycloalkyloxy, toluenesulfonyloxy, and phenyl which is further optionally substituted with OH and/or C1-3 alkoxy;
- m is 0, 1, 2;
