A compound of Formula (I):

• wherein:
• Z1 and Z2 are independently —N(R3)—;
• R1 and R2 are independently substituted alkyl, substituted aryl, heteroaryl, substituted heteroaryl, or —(W—)s-(-alk-O—)q—R, where W is selected from the group consisting of alkylene, substituted alkylene, aryl, substituted aryl, heteroaryl, and substituted heteroaryl, s is 0 or 1, R is selected from the group consisting of hydrogen, alkyl, cycloalkyl, aryl, heteroaryl, and heterocyclicalkyl, where alk is selected from the group consisting of alkylene and substituted alkylene and q is an integer from 1 to 20, provided that at least one of R1 and R2 is a group that can form a pharmaceutically acceptable acid addition salt;
• each R3 is independently hydrogen, alkyl, —(W—)s-(-alk-O—)q—R, or R3 and R1 together or R3 and R2 together with the atoms to which they are attached form a heterocyclic ring;
• X2 is aryl, substituted aryl, heteroaryl, substituted heteroaryl, alkenyl, alkynyl, cycloalkyl or heterocyclic;
• X1 and X3 are independently aryl, substituted aryl, heteroaryl, substituted heteroaryl, or —CHR4, wherein R4 is natural or unnatural amino acid side chain;
