Abstract
Photocatalytic anticancer profile of a Ir(III) photocatalyst ( Ir3 ) with strong light absorption, high turnover frequency, and excellent biocompatibility is reported. Ir3 showed selective photo-cytotoxicity against cisplatin- and sorafenib-resistant cell lines while remaining dormant to normal cell lines in the dark. Ir3 exhibited excellent photo-catalytic oxidation of cellular co-enzyme, the reduced nicotinamide adenine dinucleotide phosphate (NADPH), and amino acids via a single electron transfer mechanism. The photo-induced intracellular redox imbalance and change in mitochondrial membrane potential resulted in necrosis and apoptosis of cancer cells. Importantly, Ir3 exhibited high biocompatibility and photo-catalytic anticancer efficiency as evident from in-vivo zebrafish and mouse cancer models. To the best of our knowledge, Ir3 is the first Ir(III) based photocatalyst with such a high biocompatibility and photocatalytic anticancer therapeutic effect.
