First claim

What is claimed is:

1. A compound having a structure of Formula (IV):

or a pharmaceutically acceptable salt thereof,
wherein:
X is N or CR 5 ′, wherein R 5 ′ is selected from hydrogen, halogen, OR 6 , an optionally substituted C 1 -C 6 alkyl, an optionally substituted C 1 -C 6 haloalkyl, an optionally substituted C 1 -C 6 alkenyl, and an optionally substituted C 1 -C 6 alkynyl;
R 1 is selected from hydrogen, halogen, OR 6 , CN, NR 7 R 8 , CH 2 OR 6 , CH 2 NR 7 R 8 , an optionally substituted C 1 -C 6 alkyl, an optionally substituted C 1 -C 6 haloalkyl, an optionally substituted C 1 -C 6 alkenyl, an optionally substituted C 1 -C 6 alkynyl, CO 2 R 6 , CONR 7 R 8 , SO 3 R 6 , and SO 2 NR 7 R 8 ;
R 2 and R 3 are independently selected from hydrogen, halogen, OR 6 , NR 7 R 8 , an optionally substituted C 1 -C 6 alkyl, an optionally substituted C 1 -C 6 haloalkyl, an optionally substituted C 1 -C 6 alkenyl, and an optionally substituted C 1 -C 6 alkynyl;
R 4 is selected from halogen, OR 6 , CN, NR 7 R 8 , CH 2 OR 6 , an optionally substituted aryl, an optionally substituted heteroaryl, an optionally substituted non-aromatic ring, an optionally substituted carbocycle, an optionally substituted C 1 -C 6 alkyl, an optionally substituted C 1 -C 6 haloalkyl, an optionally substituted C 1 -C 6 alkenyl, an optionally substituted C 1 -C 6 alkynyl, CO 2 R 6 , SO 3 R 6 , SO 2 R 6 and SO 2 NR 7 R 8 ;
R 5 is selected from hydrogen, halogen, OR 6 , an optionally substituted C 1 -C 6 alkyl, an optionally substituted C 1 -C 6 haloalkyl, an optionally substituted C 1 -C 6 alkenyl, and an optionally substituted C 1 -C 6 alkynyl;
or R 4 and R 5 are linked to form an optionally substituted non-aromatic ring;
each R 6 is independently selected from an optionally substituted aryl, an optionally substituted heteroaryl, and an optionally substituted non-aromatic ring, each optionally fused with a substituted aryl or a substituted heteroaryl, hydrogen, an optionally substituted C 1 -C 10 alkyl, and an optionally substituted C 1 -C 10 haloalkyl;
each R 7 and R 8 is independently selected from an optionally substituted aryl, an optionally substituted heteroaryl, an optionally substituted non-aromatic ring, each optionally fused with a substituted aryl or a substituted heteroaryl, hydrogen, an optionally substituted C 1 -C 10 alkyl, an optionally substituted C 1 -C 10 haloalkyl, an optionally substituted C 1 -C 10 alkenyl, and an optionally substituted C 1 -C 10 alkynyl, or R 7 and R 8 are linked to form an optionally substituted non-aromatic ring;
each heteroaryl is an aromatic 5 to 8 membered ring, or a benzo- or a pyrido-fused derivative thereof, wherein up to 4 atoms forming the aromatic ring is a heteroatom selected from oxygen, sulfur, nitrogen;
each non-aromatic ring is a covalently closed 3 to 9 membered ring that does not have a delocalized π-electron system in its principle or predominant tautomer, and the atoms that form the ring include at least one carbon atom and can optionally include up to four heteroatoms selected from oxygen, sulfur, nitrogen, and phosphorus, and can optionally include one or more C(═O) or C(═S) groups as part of the ring;
each carbocycle is a covalently closed C 3 -C 9 ring, wherein each of the atoms that forms the ring is a carbon atom;
each optionally substituted group is either unsubstituted or substituted with one or more groups independently selected from alkyl, alkenyl, alkynyl, haloalkyl, aryl, arylalkyl, heteroaryl, non-aromatic ring, hydroxy, alkoxy, aryloxy, mercapto, alkylthio, arylthio, cyano, halo, —C(═O)R, —C(═S)R, —OC(═O)—NR, —NHC(═O)OR, —OC(═S)—NR, —NHC(═S)COR, —C(═O)—NR 2 , —NHC(═O)CR, —S(═O) 2 NR, —NHS(═O) 2 R, —C(═O)OR, —OC(═O)R isocyanato, thiocyanato, isothiocyanato, nitro, silyl, —S(═O) 2 CX′ 3 , ═O, ═S, and amino;
X′ is halo, and
R is alkyl, cycloalkyl, aryl, heteroaryl bonded through a ring carbon, and non-aromatic ring bonded through a ring carbon.

2. The compound of claim 1 , wherein X is N.

The compound of claim 1 , wherein R 1 is selected from NR 7 R 8 , CH 2 OR 6 , CH 2 NR 7 R 8 , an optionally substituted C 1 -C 6 alkyl, an optionally substituted C 1 -C 6 haloalkyl, an optionally substituted C 1 -C 6 alkenyl, an optionally substituted C 1 -C 6 alkynyl, CO 2 R 6 , CONR 7 R 8 , SO 3 R 6 , and SO 2 NR 7 R 8 .

4. The compound of claim 1 , wherein R 1 is selected from NR 7 R 8 , CH 2 NR 7 R 8 , or an optionally substituted C 1 -C 6 alkyl.

5. The compound of claim 1 , wherein R 1 is selected from NR 7 R 8 , or CH 2 NR 7 R 8 .
