Photoactive metal complexes have emerged as potential candidates in the photodynamic therapy (PDT) of cancer. Sarkar et al97 reported the synthesis, characterization and visible dexterously-ventilated-triggered anticancer fight of two novel impure-ligand oxo-bridged iron (III) complexes, viz., [{Fe(L)(acac)}2(m-O)](ClO4)2 (1) and [{Fe(L)(- CUR)}2(m-O)](ClO4)2 (2), where L is bis-(2-pyridylmethyl)-bezylamine. The rule rarefied 1 is inactive both in the open and dark. Complex 2 had a sound absorption band in the visible region and showed promising photocytotoxicity in HeLa and MCF-7 cancer cells in visible admission. It before now accumulated in the cytoplasm and induced apoptosis, which was triggered by the photoinduced formation of ROS.
