Xevinapant (AT406, ARRY-334543, Debio1143, SM-406)是一种有效的,拟Smac的IAP(通过E3泛素连接酶起作用的凋亡蛋白抑制剂)拮抗剂,与XIAP-BIR3, cIAP1-BIR3和cIAP2-BIR3结合,Ki为66.4 nM, 1.9 nM和5.1 nM,比作用于Smac AVPI肽亲和力高50到100倍.
Information
Xevinapant (AT406, ARRY-334543, Debio1143, SM-406) is a potent Smac mimetic and an antagonist ofIAP(inhibitor of apoptosis protein via E3 ubiquitin ligase), binding to XIAP-BIR3, cIAP1-BIR3 and cIAP2-BIR3 withKiof 66.4 nM, 1.9 nM, and 5.1 nM, 50- to 100-f
In vitro
AT-406 is a Smac mimetic and appears to mimic closely the AVPI peptide in both hydrogen bonding and hydrophobic interactions with XIAP, with additional hydrophobic contacts with W323 of XIAP. AT-406 is more sensitive to these IAPs than Smac AVPI peptide with 50-100 fold binding affinities. AT-406 (at 1 μM) completely restores the activity of caspase-9, which is suppressed by 500 nM XIAP BIR3 in a cell-free system. In MDA-MB-231 cell, AT-406 induces rapid cellular cIAP1 degradation and also pulls down the cellular XIAP protein. AT-406 effectively inhibits lots of human cancer cell lines and shows IC50 of 144 and 142 nM in MDA-MB-231 cell and SK-OV-3 ovarian cell, with low toxicity against normal-like human breast epithelial MCF-12F cells and primary human normal prostate epithelial cells. AT-406 induces apoptosis in MDA-MB-231 cell by inducing activation of caspase-3 and cleavage of PARP.
In vivo
AT-406 has good pharmacokinetic (PK) properties and oral bioavailability in mice, rats, non-human primates, and dogs. In the MDA-MB-231 xenograft, AT-406 effectively induces cIAP1 degradation and processing of procaspase-8, cleavage of PARP in tumor tissues at 100 mg/kg with well toleration even at 200 mg/kg. AT-406 induces significant tumor growth inhibition with p of 0.0012 at 100 mg/kg.
