Abstract
We performed a comparative study of the cytotoxicity of cisplatin, JM216 complex, and aminonitroxyl platinum(IV) complexes for HeLa cells grown in monolayer and 3D culture. The growth dynamics of spheroids was studied and optimal conditions for evaluation of cytotoxicity were determined. Spheroids were less sensitive to the test compounds than cells in a monolayer. The resistance index (RI) of spheroids was determined as the ratio of IC50 for spheroids to IC50 for monolayer culture. Resistance index was 5.0±1.5 for cisplatin and ranged from 1.8 to 2.3 for platinum(IV) complexes. The observed differences are related to different physicochemical properties of the complexes and different mechanisms of their penetration into cells.

Mitochondria-targeted spin-labelled luminescent iridium anticancer complexes. Chem Sci 2017; 8:8271-8278.

Abstract
Mitochondria generate energy but malfunction in many cancer cells, hence targeting mitochondrial metabolism is a promising approach for cancer therapy. Here we have designed cyclometallated iridium(iii) complexes, containing one TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl) spin label [C43H43N6O2Ir1·PF6]˙ (Ir-TEMPO1) and two TEMPO spin labels [C52H58N8O4Ir1·PF6]˙ (Ir-TEMPO2). Electron paramagnetic resonance (EPR) spectroscopy revealed spin-spin interactions between the TEMPO units in Ir-TEMPO2. Both Ir-TEMPO1 and Ir-TEMPO2 showed bright luminescence with long lifetimes (ca. 35-160 ns); while Ir-TEMPO1 displayed monoexponential decay kinetics, the biexponential decays measured for Ir-TEMPO2 indicated the presence of more than one energetically-accessible conformation. This observation was further supported by density functional theory (DFT) calculations. The antiproliferative activity of Ir-TEMPO2 towards a range of cancer cells was much greater than that of Ir-TEMPO1, and also the antioxidant activity of Ir-TEMPO2 is much higher against A2780 ovarian cancer cells when compared with Ir-TEMPO1. Most notably Ir-TEMPO2 was particularly potent towards PC3 human prostate cancer cells (IC50 = 0.53 μM), being ca. 8× more active than the clinical drug cisplatin, and ca. 15× more selective towards cancer cells versus normal cells. Confocal microscopy showed that both Ir-TEMPO1 and Ir-TEMPO2 localise in the mitochondria of cancer cells.
