SM-433, a Smac mimetic, function as inhibitor of inhibitor of apoptosis proteins (IAPs). SM-433 exhibits strong binding affinity XIAP BIR3 protein with an IC 50 <1 μM (patent WO2008128171A2).
In Vitro
SM-433 exhibits strong inhibitory activity against MDA-MB -2131 human breast cancer cells and SK-OV-3 ovarian cancer cells (IC 50 s<10 μM, respectively). MCE has not independently confirmed the accuracy of these methods. They are for reference only.
