Patent ID: 8884020

Claim:
A compound having a formula or a pharmaceutically acceptable salt thereof; wherein: Q 1 is N and Q 2 , Q 3 , Q 4 and Q 5 are C; a) P 1 , P 2 , P 3 , P 4 , P 5 and P 6 are C; or b) one of P 1 , P 2 , P 3 , P 4 , P 5 and P 6 is N and the rest are C; A and A′ taken together are ═O; R 2 is C1-C3 alkyl; each of R 4 , R 5 , R 6 and R 7 is independently: H, a halogen, —NO 2 , —CN, —C(O)OH, hydroxyl, an optionally independently substituted C 1 -C 5 alkyl, an optionally independently substituted C 2 -C 5 alkenyl, an optionally independently substituted C 2 -C 5 alkynyl, an optionally independently substituted C 1 -C 5 alkoxy, —C(O)NR a R b , or —NR a R b , wherein R a and R b are independently H, an optionally independently substituted C 1 -C 6 alkyl, or an optionally independently substituted C 3 -C 6 cycloalkyl; each of R 8 , R 9 , R 10 , R 11 and R 12 , when bonded to C, is independently: H, a halogen, —NO 2 , —CN, —C(O)OH, hydroxyl, an optionally independently substituted C 1 -C 5 alkyl, an optionally independently substituted C 2 -C 5 alkenyl, an optionally independently substituted C 2 -C 5 alkynyl, an optionally independently substituted C 1 -C 5 alkoxy, —C(O)NR a R b , or —NR a R b , wherein R a and R b are independently H, an optionally independently substituted C 1 -C 6 alkyl, or an optionally independently substituted C 3 -C 6 cycloalkyl; each of R 8 , R 9 , R 10 R 11 and R 12 , when bonded to N, is missing; R 14 is selected from H, a halogen, —NO 2 , —CN, —C(O)OH, hydroxyl, an optionally independently substituted C 1 -C 5 alkyl, an optionally independently substituted C 2 -C 5 alkenyl, an optionally independently substituted C 2 -C 5 alkynyl, an optionally independently substituted C 1 -C 5 alkoxy, —C(O)NR a R b , or —NR a R b , wherein R a and R b are independently H, an optionally independently substituted C 1 -C 6 alkyl, or an optionally independently substituted C 3 -C 6 cycloalkyl; R 16 is halogen or an optionally independently substituted methoxy and both R 13 and R 17 are H; and R 15 is missing.
