Background:

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 Kis 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[1][2].

Xevinapant (AT-406) hydrochloride potently inhibits cell growth in the MDA-MB-231 breast and SK-OV-3 ovarian cancer cell lines with IC50=144 nM and 142 nM, respectively.Xevinapant (0-3 μM; 0-48 horus) hydrochloride effectively induces cell death in a time- and dose-dependent manner[1].

Xevinapant (AT-406) hydrochloride is very effective in inhibition of tumor growth in the MDA-MB-231 xenograft model, and has minimal toxicity to animals[1]. Xevinapant hydrochloride evaluated for its pharmacokinetic (PK) properties in mice, rats, non-human primates and dogs[1].
