Summary: | Piano-stool-{CpRu} complexes containing 1,3,5-triaza-7-phosphaadamantane (PTA), N-methyl-1,3,5-triaza-7-phosphaadamantane
(mPTA), and 3,7-dimethyl-1,3,7-triaza-5-phosphabyciclo[3.3.1]nonane (dmoPTA) were evaluated as drugs against breast cancer.
'e evaluated compounds include two new examples of this family, the complexes [RuCp(DMSO-9S)(HdmoPTA)(PPh3)](CF3SO3)2
(8) and [RuCp(PPh3)2-μ-dmoPTA-19P-292N,N -PdCl2](CF3SO3) (11), which have been synthesized and characterized by NMR, IR,
and single-crystal X-ray di@raction.'e cytotoxic activity of compounds was evaluated against MDA-MB-231 breast cancer cells, and
the three most active complexes were further tested against the hormone-dependent MCF-7 breast cancer cell line. 'eir cell death
mechanism and ruthenium uptake were also evaluated, as well as their binding ability to human serum albumin.
