Gold(I) phosphinecomplexes exhibit promising properties for anticancer drug development. Here we report on a series of gold(I) phosphinecomplexes containing a naphthalimide ligand. Strong antiproliferative effects were observed in MCF-7 breast cancer cells as well as in HT-29 colon carcinoma cells. The cellular and nuclear gold levels were increased compared to analogues, in which the naphthalimide

The reaction of 4-chloro-1,8-naphthalicanhydride with sulfur and sodium sulfide in boiling ethanol lead to 4-mercapto-1,8-naphthalic anhydride. The condensation of a later compound with amines produced 4-mercapto-1,8-naphthalimides and with ethylenediamine and orthophenylenediamine, respectively, led to 4-mercapto-7H-imidazo[2,1-a]benz[d,e]isoquinoline-7-one and 4-mercapto-7H-imidazo[2,1a]benz[d,
