• each R2 and R3 is independently C1-4 alkyl;
• and
• Ring B is optionally fused to a 5-6 membered aromatic or nonaromatic ring containing up to two heteroatoms selected from N, O and S, where the 5-6 membered ring can be substituted with halo, C1-4 alkyl, C1-4 haloalkyl, or C1-4 alkoxy;
• each Y is independently selected from C1-4 alkyl, C1-4 alkoxy, CN, halo, oxo, —(CH2)pOR4, —(CH2)pN(R4)2, —(CH2)pNHC(O)R4, —(CH2)pNHCOO(C1-4 alkyl),

• q is 0, 1 or 2;
• Z3, Z4, and Z5 are independently selected from CH and N;
• L is —C(═O)—NH—[CY] or —NH—C(═O)—[CY], where [CY] indicates which atom of L is attached to CY;
• and
• CY is an aromatic ring selected from phenyl, pyridine, pyrimidine, pyrazine, pyridazine, pyridone, thiazole, isothiazole, oxazole, pyrazole, and isoxazole, wherein the ring is optionally fused to a thiophene, imidazole, oxazolone, or pyrrole ring;
• and CY is substituted with up to two groups selected from halo, CN, R5, ORS, SO2R5, OH, NH2, NHR5, and —N(R5)2,
• wherein each R5 is independently C1-4 alkyl, C4-6 heterocyclyl, or C3-8 cycloalkyl, and R5 is optionally substituted with up to three groups selected from oxo, halo, CN, R6, OH, OR6, SO2R6, NH2, NHR6, N(R6)2, NHSO2R6, NHCOOR6, NHC(═O)R6, —CH2OR7, —CH2N(R7)2, wherein each R6 is independently C1-4 alkyl, and each R7 is independently H or C1-4 alkyl;
• and two R4, R5, R6, or R7 on the same nitrogen atom can be taken together to form a 5-6 membered heterocyclic ring optionally containing an additional N, O or S as a ring member and optionally substituted with up to two groups selected from C1-4 alkyl, oxo, halo, OH, and C1-4 alkoxy.
