tetrametallic gold(I) phosphine dithiocarbamate complexes were synthesized, starting from cyclam and dimethylcyclam polyazamacrocycles, respectively, along with their monometallic gold(I) chloridophosphine precursors. Their antiproliferativeproperties were evaluated on two cancer cell lines (A549 and NSCLC-N6-L16). Most of the mono- and bimetallic complexes displayed strong activities and, in particular
A promising gold-based optical theranosticagent was conceived. This phosphine-phosphonium gold(I) complex can be tracked by two-photon imaging thanks to a coumarin moiety. It displayed strong anti-proliferative properties against cancercell lines and induced an anti-cancer effect in vivo.
