Claim 0:
1. A compound of Formula (III):, or a pharmaceutically acceptable salt, ester, amide, or prodrug thereof,
wherein
R1 is selected from the group consisting of an optionally substituted (5 to 7 membered heterocyclyl)alkyl, an optionally substituted aralkyl; and an optionally substituted (5 or 6 membered heteroaryl)alkyl;
each of R2, R3, and R4a is independently selected from the group consisting of hydrogen, halogen, C1-6 alkyl, OH, and C1-6 alkoxy;
each of R5a and R5b is independently selected from the group consisting of hydrogen, halogen, —OR6, —CN, —NR7R8, —CH2OR6, an optionally substituted aryl, an optionally substituted 5 to 10 membered heteroaryl, an optionally substituted 5-10 membered heterocyclyl, an optionally substituted C3-7 carbocyclyl, an optionally substituted C1-6 alkyl, an optionally substituted C1-6 haloalkyl, an optionally substituted C1-6 heteroalkyl, —C(═O)R6, —C(═O)OR6, —C(═O)NR7R8, —NHC(═O)R6, —SO2R6, and —SO2NR7R8;
each R6 is independently hydrogen, an optionally substituted C1-10 alkyl, an optionally substituted C1-10 haloalkyl, or an optionally substituted C1-6 heteroalkyl; and
each R7 and R8 is independently selected from hydrogen; an optionally substituted C1-10 alkyl; an optionally substituted C1-10 haloalkyl; or an optionally substituted C1-6 heteroalkyl; or R7 and R8 are joined together with the nitrogen atom to which they are attached to form an optionally substituted C3-7 cycloalkyl or 3 to 7 membered heterocyclyl ring.
