A compound of Formula (I):

• or a pharmaceutically acceptable salt, solvate, or prodrug thereof, wherein:
• R1 is C1-C4 alkyl;
• R2a and R2b are each independently hydrogen, halogen, or C1-C4 alkyl;
• R3 is hydrogen, —(C1-C4 alkylene)-OH, or —(C1-C4 alkylene)-NH2;
• R4 is hydrogen or C1-C4 alkyl;
• each R5 and R6 is independently hydrogen, halogen, or C1-C4 alkyl;
• R7 is C1-C6 alkyl, C1-C6 alkoxy, C1-C6 heteroalkyl, C3-C6 cycloalkyl, 4- to 6-membered heterocycloalkyl, —O—(C3-C6 cycloalkyl), —O-(4- to 6-membered heterocycloalkyl), —(C1-C4 alkylene)-(C3-C6 cycloalkyl), —(C1-C4 alkylene)-(4- to 6-membered heterocycloalkyl), —O—(C1-C4 alkylene)-(C3-C6 cycloalkyl), —O—(C1-C4 alkylene)-(4- to 6-membered heterocycloalkyl), —(C1-C4 alkylene)-O—(C3-C6 cycloalkyl), or —(C1-C4 alkylene)-O-(4- to 6-membered heterocycloalkyl);
• wherein the alkyl, alkoxy, heteroalkyl, cycloalkyl, or heterocycloalkyl is unsubstituted or substituted by 1, 2, or 3 groups independently selected from —OR8, —N(R8)2, —CO2R8, —CON(R8)2, —CH2N(R8)2, —NHCOR8, —NHSO2R8, —CH2CN, C1-C4 alkyl, C1-C4 hydroxyalkyl, —C(═O)—C1-C4 hydroxyalkyl, C1-C4 methoxyalkyl, and C1-C4 aminoalkyl;
• each R8 is independently hydrogen, C1-C4 alkyl, —C(═O)—C1-C4 alkyl, or 4- to 6-membered heterocycloalkyl, wherein the alkyl or heterocycloalkyl is unsubstituted or substituted by 1, 2, 3, or 4 groups independently selected from —F, —CN, —OH, —CH2OH, —NH2, —OMe, —N(CH3)2, —CO2H, —CONH2, —SO2CH3, —C(═NH) NH2, phenyl, and monocyclic heteroaryl which is unsubstituted or substituted by 1 or 2 groups selected from —F, —CN, —OH, —NH2, —OMe, —N(CH3)2, —CO2H, —CONH2, and —SO2CH3;
• or two R8 attached to the same nitrogen are taken together to form a 4- to 6-membered heterocycloalkyl which is unsubstituted or substituted by 1, 2, or 3 groups independently selected from —F, —CN, —OH, —NH2, —OMe, —CO2H, —CONH2, and —SO2CH3;
• s is 1 or 2;
