at-iap

AT-IAP is an effective dual antagonist of XIAP and cIAP1.

PROTAC ERα Degrader-2 is composed of a cIAP1 ligand binding group, a linker, and an estrogen receptor α (ERα) binding group, serving as an ERα degrader. It achieves maximal ERα degradation in human mammary tumor MCF7 cells at a concentration of 30 μM. Degradation inducers that utilize cIAP1 are referred to as specific and non-genetic IAP-dependent protein erasers (SNIPERs)[1].

PROTAC RAR Degrader-1, an RAR degrader, consists of a cIAP1 ligand binding group, a linker, and an RAR ligand binding group. It achieves maximal RAR degradation at a concentration of 30 μM in HT1080 cells. Degradation inducers that utilize cIAP1 are known as specific and non-genetic IAP-dependent protein erasers (SNIPERs)[1].

CST 530 is a monovalent IAP antagonist. It induces cIAP1 and cIAP2 autodegradation in MM.1S cells (cIAP1 degradation at 0.1 μM and cIAP2 degradation at 1 μM after 16 hours). CST 530 reduces cell viability in multiple cancer cell lines including SUDHL6, MOLM13, and HEL (IC50 values ​​of 170 nM, 420 nM, and 450 nM, respectively).

Xevinapant hydrochloride (AT-406 HCl) , an orally active antagonist of multiple inhibitor of apoptosis proteins(IAP), inhibits progression of human ovarian Y 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.

Xevinapant (Debio-1143) 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.
