XIAP Selective Inhibitors | Antagonists

Catalog No. Product Name Information Selective / Pan IC50 / Ki
S7089 SM-164

SM-164 is a potent, non-peptide, cell-permeable antagonist of XIAP that targets both the BIR2 and BIR3 domains with IC50 of 1.39 nM. SM-164 induces apoptosis and tumor regression.

Selective XIAP, IC50: 1.39 nM
S7025 Embelin

Embelin (Embelic Acid, NSC 91874), a quinone isolated from the Japanese Ardisia herb, is an inhibitor of X-linked inhibitor of apoptosis (XIAP) with IC50 of 4.1 μM in a cell-free assay.

Selective XIAP, IC50: 4.1 μM
S9634 Phenoxodiol (Haginin E)

Phenoxodiol (Haginin E, Idronoxil, Dehydroequol, NV 06, PXD) is an isoflavone analog with antineoplastic activity that activates the caspase system, inhibits XIAP (X-linked inhibitor of apoptosis), and disrupts FLICE inhibitory protein (FLIP) expression, resulting in tumor cell apoptosis. Phenoxodiol also inhibits DNA topoisomerase II.

Selective
S5600 Flavokawain A

Flavokawain A, extracted from kava, is an apoptotic inducers and anticarcinogenic agent. Flavokawain A can down-regulation of antiapoptotic proteins, such as XIAP, survivin, and Bcl-xL, thereby changing the balance between apoptotic and antiapoptotic molecules and then induce cell death in tumor cells.

Selective
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 XIAP, 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 XIAP-BIR2, Ki: 112 nM; XIAP-BIR3, Ki: 28 nM
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 XIAP, IC50: 40 nM
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.

Pan XIAP, Kd: 45 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.

Pan XIAP-BIR3, Ki: 66.4 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).

S7597 BV-6

BV-6 is a SMAC mimetic, dual cIAP and XIAP inhibitor.
