Cathepsin inhibitors

A compound of formula I:

• wherein:
• R1 is —S(O)2Ra, —C(O) Ra, —H, —X, —CN, —C1-C6 substituted or unsubstituted alkyl, —C3-C6 substituted or unsubstituted cycloalkyl, —C1-C6 alkoxy, —C3-C6 cycloalkoxy, —NHC(O) Ra, —NHC(O) NHRa, —C2-C5 lactam, or —C1-C4 cyclourea;
• and R1 is located para or meta to the phenylene moiety;
• R2 is —C1-C4 alkyl, —C1-C4 haloalkyl, or ═O;
• R3 is —C2-C6 alkyl, or —C2-C6 haloalkyl;
• R4 and R5 are independently selected from —H, —C1-C3 alkyl, or —C1-C3 haloalkyl, or R4 and R5 together with the carbon atom to which they are attached form a C3-C6 cycloalkyl, C3-C6 heterocycloalkyl, or C3-C6 cyclohaloalkyl;
• R6 is —H, —Y, —CH3, —CY3, —CHY2, or —CH2Y;
• each R7 is independently selected from —H, —X, —CN, —C1-C4 alkyl, —C1-C4 haloalkyl, or —C1-C3 alkoxy;
• each R8 is independently selected from —X, —C1-C4 alkyl, or —C1-C4 haloalkyl;
• Ra is —H, —C1-C6 substituted or unsubstituted alkyl, —NH2, or —NR9R10;
• each X is independently selected from —F, —Cl, —Br, or —I;
• R9 and R10 are independently selected from —H, —C1-C3 alkyl, or —C1-C3 haloalkyl;
• or R9 and R10 together with the nitrogen atom to which they are attached form a C3-C6 heterocycloalkyl or C3-C6 heterocyclohaloalkyl;
• Y is —F, —Cl, —Br, or —I;
• m is 0, 1, 2, 3, or 4;
• and
• n is 0, 1 or 2,
• or a pharmaceutically acceptable salt, stereoisomer, or prodrug thereof.
