Bz-423 has been used as a mitochondrial inner membrane pore (MIMP) reagent to study its effect on oxygen consumption rate (OCR) and ATP synthesis in HepG2 cells.
Bz-423 is an inhibitor of mitochondrial F1F0 ATP synthase. It binds the oligomycin sensitivity conferring protein (OSCP) component of mitochondrial F1F0-ATPase, resulting in superoxide generation and apoptosis. BZ-423 was shown to block multidrug-resistant melanoma cells. In another study, Bz-423 selectively increased superoxide and induced the apoptosis of alloreactive T cells, which arrested established Graft versus Host Disease.
