Abstract
A water‐soluble cationic gallium corrole, 5,10,15‐tris(N‐methyl‐4‐pyridyl)corrolatogallium(III) (3), was prepared and characterized. The photocytotoxicity of 3 was investigated using Hep G2 cancer cell line. Upon treatment with corrole 3 and irradiation, fragmentation of tumor cell nuclei was observed, which led to apoptosis. Flow cytometric analysis clearly showed the efficient induction of apoptotic cell death, and corrole 3 exhibited high photocytotoxicity towards Hep G2 cancer cells (IC50 = 60 nM). Furthermore, the binding behavior of corrole 3 with c‐MYC G‐quadruplex DNA, a potent target for antitumor drugs, was investigated using spectroscopic methods and molecular docking simulation.
