Compounds made up of a homodimer or heterodimer having monomeric units of formula (I): wherein: each A is, independently, NR1R2, or N+R1R2R3; each B is, independently, optionally substituted alkyl, alkenyl, or alkynyl, wherein one or more hydrogens are optionally replaced by fluorine; each U is, independently, CONH, C(O)O, C(S)O, C(S)NH, C(NH)NH, (CH2)1-5, or the inverse, thereof, wherein one or more carbons are optionally replaced by a heteroatom selected from O, S, and N; each V and W is, independently, (CH2)1-5, wherein one or more carbons are optionally replaced by C═O, C═S, or a heteroatom selected from O, S, and N, and one or more hydrogens are optionally replaced by a branched or unbranched alkyl or cycloalkyl, an optionally substituted aryl, arylalkyl, heteroaryl, heteroarylalkyl, OR4, SR4, or NR4R5; each X is, independently, optionally substituted alkyl, alkenyl, alkynyl, aryl, or heteroaryl, wherein one or more carbons are optionally replaced by C═O, C═S, or a heteroatom selected from O, S, and N, and one or more hydrogens are optionally replaced by a branched or unbranched alkyl or cycloalkyl, an optionally substituted aryl, arylalkyl, heteroaryl, heteroarylalkyl, OR4. SR4, or NR4R5; each Y is, independently, CH or N; each Z is, independently, CH2, C═O, C═S, CHSR, CHOR, or CHNR, compositions, and methods of using such compounds to modulate apoptosis including IAP antagonists are provided herein. Compositions including mimetics of the invention and, optionally, secondary agents, may be used to treat proliferative disorders such as, cancer and autoimmune diseases.
