Claim 17:
18. A method for treating a viral infection in a subject, the method comprising administering to the subject an effective amount of a compound having a structure represented by a formula:, wherein n is 0, 1, or 2;
wherein p is 0 or 1;
wherein A is O, S, or NH;
wherein R1 is selected from hydrogen and C1-C4 alkyl;
wherein each of R2a and R2b is independently selected from hydrogen, halogen, C1-C6 alkyl, C1-C4 haloalkyl, C1-C8 alkoxy, C1-C8 haloalkoxy, C1-C8 cyanoalkoxy, —OCy2, —OAr1, —O(C1-C4 alkyl)OR10, —O(C1-C4 alkyl)Ar1, —CO2R10, and Cy2;
wherein each occurrence of R10, when present, is independently selected from hydrogen and C1-C4 alkyl;
wherein each occurrence of Ar1, when present, is independently selected from C2-C5 heteroaryl and C6-C12 aryl, and is substituted with 0, 1, 2, or 3 groups independently selected from halogen, —CN, —NH2, —OH, —NO2, C1-C4 alkyl, C2-C4 alkenyl, C1-C4 haloalkyl, C1-C4 cyanoalkyl, C1-C4 hydroxyalkyl, C1-C4 haloalkoxy, C1-C4 alkoxy, C1-C4 alkylamino, (C1-C4)(C1-C4) dialkylamino, and C1-C4 aminoalkyl;
wherein each occurrence of Cy2, when present, is independently selected from C3-C6 cycloalkyl, C3-C6 heterocycloalkyl, and phenyl, and is substituted with 0, 1, 2, or 3 groups independently selected from halogen, —CN, —NH2, —OH, —NO2, C1-C4 alkyl, C2-C4 alkenyl, C1-C4 haloalkyl, C1-C4 cyanoalkyl, C1-C4 hydroxyalkyl, C1-C4 haloalkoxy, C1-C4 alkoxy, C1-C4 alkylamino, (C1-C4)(C1-C4) dialkylamino, and C1-C4 aminoalkyl;

or wherein R2a and R2b are covalently bonded and, together with the intermediate atoms, comprise a C5-C6 cycloalkyl, a C2-C5 heterocycloalkyl, a C6 aryl or a C2-C5 heteroaryl, and are substituted with 0, 1, 2, or 3 groups independently selected from selected from halogen, —CN, —NH2, —OH, —NO2, C1-C4 alkyl, C2-C4 alkenyl, C1-C4 haloalkyl, C1-C4 cyanoalkyl, C1-C4 hydroxyalkyl, C1-C4 haloalkoxy, C1-C4 alkoxy, C1-C4 alkylamino, (C1-C4)(C1-C4) dialkylamino, and C1-C4 aminoalkyl; and
wherein each of R3a and R3b, when present, is independently selected from hydrogen, halogen, C1-C4 alkyl, and C1-C4 haloalkyl;
or wherein R3a and R3b, when present, are covalently bonded and, together with the intermediate atoms, comprise a C3-C4 cycloalkyl substituted with 0, 1, 2, or 3 groups independently selected from selected from halogen, —CN, —NH2, —OH, —NO2, C1-C4 alkyl, C2-C4 alkenyl, C1-C4 haloalkyl, C1-C4 cyanoalkyl, C1-C4 hydroxyalkyl, C1-C4 haloalkoxy, C1-C4 alkoxy, C1-C4 alkylamino, (C1-C4)(C1-C4) dialkylamino, and C1-C4 aminoalkyl;
wherein Cy1 is selected from C2-C9 heteroaryl, C6 aryl, and adamantyl, and is substituted with 0, 1, 2, or 3 groups independently selected from halogen, —CN, —NH2, —OH, —NO2, C1-C4 alkyl, C2-C4 alkenyl, C1-C4 haloalkyl, C1-C4 cyanoalkyl, C1-C4 hydroxyalkyl, C1-C4 haloalkoxy, C1-C4 alkoxy, C1-C4 alkylamino, (C1-C4)(C1-C4) dialkylamino, C1-C4 aminoalkyl, and C3-C6 cycloalkyl;
provided that when p is 1, A is S, and Cy1 is C6 aryl, then Cy1 is not substituted with a halogen group,
or a pharmaceutically acceptable salt thereof, wherein the viral infection is due to an Alphavirus, thereby treating the viral infection.
