IR-783 (ADS 780WS) is a heptamethine cyanine dye. IR-783 induces Mitochondrial membrane potential loss, ATP depletion, mitochondrial permeability transition pore opening, Cytochrome c release and Apoptosis in breast cancer cells. IR-783 promotes the translocation of Drp1 from the cytosol to mitochondria. IR-783 increases the expression of mitochondrial fission proteins such as MFF and Fission-1. IR-783 possesses imaging, cancer-targeting and anticancer properties. IR-783 exerts anticancer effects against breast cancer. IR-783 can be used in breast cancer-related research[1].
