Organoiridium(III) complexes containing N,P-ligands and their antiproliferative activity in 2D and 3D cell-based models
Original language description
Platinum-based cytostatic drugs are taken as etalon in the cancer therapy; however, they possess many adverse side effects. This fact leads to the developing of new non-platinum metallodrugs with different mechanism of action (MoA). One such group is represented by half-sandwich iridium(III) complexes, which offer high antiproliferative activity and different MoA than conventional platinum-based drugs. Herein we report on a series of [Ir(η5 Cp*)Cl(LNP)]PF6 (1–3) and [Ir(η5 Cpph)Cl(LNP)]PF6 (4–6) complexes involving three different N,P-donor phosphinoalkylamines (LNP); HCp* = pentamethylcyclopentadiene and HCpph = (2,3,4,5-tetramethylcyclopenta-2,4-dien-1-yl)benzene. The most potent complexes 3 and 6 bearing 3-(diphenylphosphanyl)propan-1-amine possessed the highest cytotoxic effect against different cancer cell lines (THP-1, HeLa, SW982, A549, MOR) including cisplatin-resistant lung carcinoma cell line (MOR/CPR) (IC50 values lie between 3.1 and 9.1 μM for particular cell lines). On the other hand, complex 3, but not 6, did not decrease cell viability of non-cancerous cells (chondrocytes, PBMCs) under 50% at the concentration of 20 µM. The cytotoxic effect was further demonstrated on 3D lung cancer cell spheroids, which revealed anti-cancer and anti-migration potential of complexes 3 and 6. The cell cycle and the cell death analyses showed a different mechanism in comparison with the effect of cisplatin. Moreover, we described for the first time that organoiridium complexes trigger the expression of stress-related genes connected with oxidative stress, DNA damage, and endoplasmic reticulum stress.
