Embelin (Embelic acid), a potent, nonpeptidic XIAP inhibitor (IC₅₀=4.1 μM), inhibits cell growth, induces apoptosis, and activates caspase-9 in prostate cancer cells with high levels of XIAP. Embelin blocks NF-kappaB signaling pathway leading to suppression of NF-kappaB-regulated antiapoptotic and metastatic gene products. Embelin also induces autophagic and apoptotic cell death in human oral squamous cell carcinoma cells.

Tolinapant (ASTX660) is an orally bioavailable dual antagonist of cellular inhibitor of apoptosis protein (cIAP) and X-linked inhibitor of apoptosis protein (XIAP).

SM-164 hydrochloride is a cell-permeable Smac mimetic compound. SM-164 binds to XIAP protein containing both the BIR2 and BIR3 domains with an IC₅₀ value of 1.39 nM and functions as an extremely potent antagonist of XIAP.

Dasminapant (APG-1387), a bivalent SMAC mimetic and an IAP antagonist, blocks the activity of IAPs family proteins (XIAP, cIAP-1, cIAP-2, and ML-IAP). Dasminapant induces degradation of cIAP-1 and XIAP proteins, as well as caspase-3 activation and PARP cleavage, which leads to apoptosis. Dasminapant can be used for the research of hepatocellular carcinoma, ovarian cancer, and nasopharyngeal carcinoma.

Xevinapant (AT-406) hydrochloride is a potent and orally bioavailable Smac mimetic and an antagonist of the inhibitor of apoptosis proteins (IAPs). Xevinapant hydrochloride binds to XIAP, cIAP1, and cIAP2 proteins with K_is of 66.4, 1.9, and 5.1 nM, respectively. Xevinapant hydrochloride effectively antagonizes XIAP BIR3 protein in a cell-free functional assay, induces rapid degradation of cellular cIAP1 protein, and inhibits cancer cell growth in various human cancer cell lines. Xevinapant hydrochloride is highly effective in induction of apoptosis in xenograft tumors.

AZD5582 dihydrochloride is an antagonist of the inhibitor of apoptosis proteins (IAPs), which binds to the BIR3 domains cIAP1, cIAP2, and XIAP with IC₅₀s of 15, 21, and 15 nM, respectively. AZD5582 induces apoptosis.

SM-1295 is an inhibitor of apoptosis protein (IAP) antagonist, with K_d values of 3077 nM, 3.2 nM and 9.5 nM for XIAP-BIR3, c-IAP1-BIR3 and c-IAP2-BIR3, respectively.

SBP-0636457 (SB1-0636457) is a SMAC mimetic, and as an IAP antagonist. SBP-0636457 binds to the BIR-domains of the IAP proteins, with a K_i of 0.27 μM. SBP-0636457 can be used for the research of solid tumors and hematologic cancers.

MV1 is an antagonist of IAP (inhibitor of apoptosis protein), leads to protein knockdown of HaloTag-fused proteins when combined with HaloTag ligand.

CST530 is an inhibitor of apoptosis protein (IAP) antagonist. CST530 is an IAP-type Ligands for E3 Ligase. CST530 binds to the BIR3 domain of IAP and interferes with its function, thereby promoting the ubiquitination and degradation of cIAP1. CST530 can be used to prepare PROTACs.

BV6 TFA is an antagonist of cIAP1 and XIAP, members of the inhibitors of apoptosis (IAP) family. BV6 TFA shows an IC₅₀ of 7.2 μM in MTS assays in HCC193 cells. BV6 TFA can be used in the research of endometrial cancer and endometriosis.
