The present invention provides compounds which are tautomers, stereoisomers, hydrates, solvates, salts or prodrugs of the compound of formula (A) or the compound of formula (A). , R However, R 1 and R 2 are independently selected from H, C 1 -C 10 alkyl, C 3 -C 10 cycloalkyl, C 1 -C 10 alkoxy, halogen and -CN, respectively, and R 3 , R 4 and R 5 are independently selected from C 1 -C 10 alkyl, C 3 -C 10 cycloalkyl, C 1 -C 10 alkoxy, halogen and -CN, respectively, with the premise that R 1 is -CH. 3. If Cl or -CN, then R 2 is not H, and if R 1 is H, then R 2 is not H, -CN or -CH 3 . |
