“…The best SI values for Ph3P-Au-tuH complex were found for the glioma (U251, SI = 4.07), renal (786-0, SI = 2.65) and leukemia lines (K-562, SI = 24.4). According to the literature, the chlorido(triphenylphosphine)gold(I) (Ph3P-Au-Cl) compound is able to induce apoptosis in breast tumor cells (MCF-7) with low level of ct-DNA interaction, and Ph3P-Au-Cl interacts with sulphydryl groups present in serum albumin (BSA) [145]. These activities could partially explain the antiproliferative effect observed for Ph3P-Au-Cl.…”
