A compound of the formula (I) or a salt thereof:

• wherein
• R1 and R2 are each independently hydrogen, halogen, C1-8 alkyl, —CN, or C1-8 haloalkyl, provided that at least one of R1 or R2 is other than hydrogen;
• each R3 is independently hydrogen, halogen, or C1-4 alkyl;
• R4 is hydrogen or C1-8 alkyl;
• R5 is hydrogen, halogen, or C1-8 alkyl optionally substituted with methoxy;
• R6 is hydrogen or C1-4 alkyl;
• R11 is selected from the group consisting of hydrogen, C1-8 alkyl, C2-8 alkenyl, C2-8 alkynyl, substituted or unsubstituted C6-10 aryl, substituted or unsubstituted 5-to 10-membered heteroaryl, and substituted or unsubstituted 3- to 10-membered heterocycle;
• X1 is CR7, N, or NO;
• X2 and X4 are each independently N or NO;
• X3 is CR7;
• X6 and X7 are each independently selected from CR7, N, and NO;
• each R7 is independently selected from the group consisting of hydrogen, halogen, substituted or unsubstituted C1-8 alkyl, substituted or unsubstituted C2-8 alkenyl, substituted or unsubstituted C2-8 alkynyl, —CN, —NO2, —OR8, —OC(O)R8, —CO2R8, —C(O)R8, —C(O)NR9R8, —OC(O)NR9R8, —NR10C(O)R8, —NR10C(O)NR9R8, —NR9R8, —NR10CO2R8, —SR8, —S(O)R8, —S(O)2R8, —S(O)2NR9R8, —NR10S(O)2R8, substituted or unsubstituted C6-10 aryl, substituted or unsubstituted 5- to 10-membered heteroaryl and substituted or unsubstituted 3- to 10-membered heterocyclyl;
