WebNov 3, 2016 · Surgery and radiotherapy are key players for treating primary non-metastasised solid tumours, but for patients with co-morbidities that are unfit for surgery, deep-seated tumours, especially those associated with major blood vessels, or brain tumours, combined chemotherapy approaches are common. Webtriphenylphosphine monosulfonate cause death of metastatic melanoma (MV3) and nonmalignant cell lines. Three mechanisms have been proposed to explain the toxicity of Au55 clusters: the first, their perfect fit in the major grooves of DNA, the second, increased ROS production and the third, blockage of membrane ion channels (Tsoli et al 2005, Pan
