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 & PRIME,-(p-tolyl)-2,2 & PRIME,:6 & PRIME,,2 & DPRIME,-terpyridine,C^N = deprotonated 2-arylbenzimidazole backbone) to introduce newmetal-based compounds for effective inhibition of metastatic processesin triple-negative breast cancer (TNBC). The results show that thestructural modifications within the C^N scaffold strongly impact theantimetastatic properties of these complexes in TNBC cells. Furthermore,testing the antimetastatic effects of the investigated Ir complexesrevealed that the highest antimetastatic activity in TNBC cells isexhibited by complex Ir1. This result was in contrastto the effects of the clinically used drug doxorubicin used in conventionalchemotherapy of TNBC, which conversely promoted metastatic propertiesof TNBC cells. Thus, the latter result suggests that doxorubicin chemotherapymay increase the risk of metastasis of breast cancer cells, so thesearch for new drugs to treat breast cancer that would show betterantitumor effects than doxorubicin is justified.
