Birinapant binds with XIAP and cIAP1 with Kd of 45 and Birinapant in combination with TNF-α exhibits a strong antimelanoma effect in vitro. Birinapant in combination with TNF-α(1 ng/mL) inhibits the growth of human melanoma cell lines WTH202, WM793B, WM1366 and WM164 with IC50s of 1.8, 2.5, 7.9 and 9 nM, respectively, while neither compound is effective individually. Birinapant singly treatment induces inhibition on proliferation of WM9 cells with IC50 of 2.4 nM. Birinapant significantly inhibits the target protein cIAP1 and cIAP2 in these cell lines.

Birinapant (30 mg/kg) treatment significantly induces abrogation of tumor growth in melanoma xenotransplantation models 451Lu with.
