GSTM1 and neoplasm: It is shownthat with the catalysis of intracellular H2O2 and loaded Hb, luminol units excite the Ir2 core toproduce type I and II ROS through CRET; IrL2H promotescell apoptosis and even induces cell death under hypoxic conditions.In vivo, IrL2H achieves tumor imaging within 3 h andinhibits tumor growth in 4T1-bearing mouse models through intratumoralinjection.
