1. A compound having a structure represented by a formula:

OG Complex Work Unit Chemistry
wherein R1 is selected from hydrogen and C1-C4 alkyl;
wherein Ar1 is selected from monocyclic aryl and pyridinyl, and is substituted with 0, 1, 2, or 3 groups independently selected from halogen, —CN, —NH2, —OH, C1-C4 alkyl, C1-C4 haloalkyl, C1-C4 hydroxyalkyl, C1-C4 alkoxy, C1-C4 alkylamino, and (C1-C4)(C1-C4) dialkylamino;
wherein Ar3 is pyridinyl substituted with 0, 1, 2, or 3 R4 groups; and
wherein each occurrence of R4 is independently selected from halogen, —CN, —NH2, —OH, C1-C4 alkyl, C1-C4 haloalkyl, C1-C4 hydroxyalkyl, C1-C4 alkoxy, C1-C4 alkylamino, and (C1-C4)(C1-C4) dialkylamino,
or a pharmaceutically acceptable salt thereof.
