Anti-TNBC agent-8

Anti-TNBC agent-8 (Compound TP2) is a photodynamic therapeutic agent targeting mitochondrial DNA G4 (mtG4) . Under white light irradiation, its IC50 against 4T1 cells is 0.42 μM. anti-TNBC agent-8 binds tightly to mtG4 and generates a large amount of reactive oxygen species (ROS) under white light irradiation, leading to the loss of mitochondrial membrane potential (MMP), a decrease in ATP production, and an increase in the ROS level. This, in turn, induces significant apoptosis in triple-negative breast cancer (TNBC) cells, exerting the activity of inhibiting tumor cell growth. anti-TNBC agent-8 can be used in the research of triple-negative breast cancer.
