S7015 Birinapant (TL32711)

Birinapant (TL32711) is a SMAC mimetic antagonist, mostly to cIAP1 with Kd of <1 nM in a cell-free assay, less potent to XIAP. Birinapant helps to induce apoptosis in latent HIV-1-infected cells. Phase 2.

Selective cIAP1, Kd: <1 nM
S2754 Xevinapant (AT406)

Xevinapant (AT406, ARRY-334543, Debio1143, SM-406) is a potent Smac mimetic and an antagonist of IAP (inhibitor of apoptosis protein via E3 ubiquitin ligase), binding to XIAP-BIR3, cIAP1-BIR3 and cIAP2-BIR3 with Ki of 66.4 nM, 1.9 nM, and 5.1 nM, 50- to 100-fold higher affinities than the Smac AVPI peptide. Phase 1.

Selective cIAP1-BIR3, Ki: 1.9 nM; cIAP2-BIR3, Ki: 5.1 nM
S2271 Berberine chloride (NSC 646666)

Berberine chloride (NSC 646666, Natural Yellow 18) is a quaternary ammonium salt from the group of isoquinoline alkaloids. Berberine activates caspase 3 and caspase 8, cleavage of poly ADP-ribose polymerase (PARP) and the release of cytochrome c. Berberine chloride decreases the expression of c-IAP1, Bcl-2 and Bcl-XL. Berberine chloride induces apoptosis with sustained phosphorylation of JNK and p38 MAPK, as well as generation

S8681 Tolinapant (ASTX660)

Tolinapant (ASTX660) is a potent, non-peptidomimetic antagonist of cIAP1/2 and XIAP that inhibits the interactions between a SMAC-derived peptide and the BIR3 domains of XIAP (BIR3-XIAP) and cIAP1 (BIR3-cIAP1) with IC50 values less than 40 and 12 nmol/L, respectively.

Pan cIAP1, IC50: 12 nM; cIAP2, :
S7362 AZD5582

AZD5582, a novel small-molecule IAP inhibitor, binds potently to the BIR3 domains of cIAP1, cIAP2, and XIAP with IC50 values of 15, 21, and 15

Pan cIAP2, IC50: 21 nM; cIAP1, IC50: 15 nM
S7010 GDC-0152

GDC-0152 is a potent antagonist of XIAP-BIR3, ML-IAP-BIR3, cIAP1-BIR3 and cIAP2-BIR3 with Ki of 28 nM, 14 nM, 17 nM and 43 nM in cell-free assays, respectively; less affinity shown to cIAP1-BIR2 and cIAP2-BIR2. Phase 1.

Pan cIAP1-BIR3, Ki: 17 nM; cIAP2-BIR3, Ki: 43 nM
S7009 LCL161

LCL-161, a small molecule second mitochondrial activator of caspase (SMAC) mimetic, potently binds to and inhibits multiple IAPs (i.e. XIAP, c-IAP).
