Patent ID: 8470803

Claim:
A compound having a structure according to the formula: wherein X is selected from the group consisting of CH, C(CN), CR b and N; Y is selected from the group consisting of CH, C(CN), CR b and N; a is 0 or 1; b is 0 or 1; R 4 is selected from the group consisting of H, unsubstituted C 1 -C 6 alkyl, COR 10 , and —C(O)OR 10 , wherein R 10 is H or unsubstituted C 1 -C 6 alkyl; with the proviso that when X or Y is C(CN), then a is 0; with the proviso that when X or Y is CR b , then b is 0; with the proviso that X and Y cannot both be C(CN); with the proviso that X and Y cannot both be CR b ; R b is selected from the group consisting of OR 4 , NR 4 R 5 , SR 4 , —S(O)R 4 , —S(O) 2 R 4 , —S(O) 2 NR 4 R 5 , —C(O)R 4 , —C(O)OR 4 , —C(O)NR 4 R 5 , nitro, cyano, halogen, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl, wherein R 4 and R 5 are each independently selected from the group consisting of H, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl with the proviso that R 4 and R 5 , together with the atoms to which they are attached, are optionally combined to form a 5- to 7-membered substituted or unsubstituted heterocycloalkyl ring or a salt thereof.
