Ir(III) Compounds Containing a Terdentate Ligand Are Potent Inhibitors of Proliferation and Effective Antimetastatic Agents in Aggressive Triple-Negative Breast Cancer Cells.

ABSTRACT: Herein, we report a series of new octahedral iridium(III) complexes Ir1-Ir9 of the type [Ir(N^N^N)(C^N)Cl]PF₆ (N^N^N = 4'-(p-tolyl)-2,2':6',2″-terpyridine; C^N = deprotonated 2-arylbenzimidazole backbone) to introduce new metal-based compounds for effective inhibition of metastatic processes in triple-negative breast cancer (TNBC). The results show that the structural modifications within the C^N scaffold strongly impact the antimetastatic properties of these complexes in TNBC cells. Furthermore, testing the antimetastatic effects of the investigated Ir complexes revealed that the highest antimetastatic activity in TNBC cells is exhibited by complex Ir1. This result was in contrast to the effects of the clinically used drug doxorubicin used in convent
