We report the anti-breast cancer stem cell (CSC) properties of a series of Group 10-bis(azadiphosphine) complexes 1–3 under exclusively three-dimensional cell culture conditions. The breast CSC mammosphere potency of 1–3 is dependent on the Group 10 metal present, increasing in the following order: 1 (nickel complex) <2 (palladium complex) <3 (platinum complex). Notably, 3 reduces the formation and size of mammospheres to a greater extent than salinomycin, an established CSC-active compound, or any reported anti-CSC metal complex tested under similar conditions. Mechanistic studies suggest that the most effective complexes 2 and 3 readily penetrate CSC mammospheres, enter CSC nuclei, induce genomic DNA damage, and trigger caspase-dependent apoptosis. To the best of our knowledge, this is the first study to systematically probe the anti-CSC activity of a series of structurally related Group 10 complexes and to be conducted entirely using three-dimensional CSC culture conditions.
