Claim:
A compound having a structure according to Formula I or II: wherein, ring A is a saturated or partially saturated five to seven membered heterocyclic ring, or a five to seven membered heteroaryl ring, containing one or more hetero atoms independently selected from —O—, —N—, and —S—; ring B is a saturated or partially saturated five to seven membered heterocyclic ring, or a five to seven membered heteroaryl ring, containing one or more hetero atoms independently selected from —O—, —N—, and —S—, wherein ring B is attached to the remainder of the molecule via a ring carbon; R1 is attached to a B-ring heteroatom and is selected from H, C 1-6 alkyl, branched C 1-6 alkyl, formyl, acetyl, carboxylate, carboxamide, a natural or unnatural amino acid, D- or L-lactic acid, and hydroxy acetic acid; R2 and R3 are independently selected from H, halo, C 1-6 alkyl, C 1-6 alkoxy, acyl, sulfonyl, sulfamoyl, sulfonate, carboxylic acid, ester, carboxamide, and cycloalkyl; n is 0, 1, 2, 3, 4, or 5; and R5 is selected from F, Cl, Br, I, CF 3 , NO 2 , CN, CH 2 NH 2 , CH 2 NHCH 3 , CH 2 NMe 2 , —CO 2 CH 3 , CO 2 C 2 H 5 , —NHCH 3 , and —NMe 2 ; and pharmaceutically acceptable salts thereof.
