Biological Activity for Bz 423

Bz 423 is an ATP synthase inhibitor (IC₅₀ ~5 μM). Binds the oligomycin sensitivity conferring protein (OSCP) component of mitochondrial F₁F₀-ATPase in vitro resulting in generation of superoxide and apoptosis. Kills primary B and T cell in mice in vivo. Suppresses autoimmunity and prolongs survival in mouse lupus model.
