Cancer is a disease that is responsible for many deaths worldwide. It is therefore crucial to synthesise and evaluate new anticancer agents that may be more effective towards the cancer cells. A number of silver(I) p-substituted phenyl diphenyl phosphine complexes, were synthesised in a 1:2 M ratio of silver thiocyanate to phosphine ligand. Once characterised, these complexes, [Ag{PPh2(4-C6H4CH=CH2)-kappa p}(2)-mu-SCN-kappa S-2:N;kappa N-2:S](2) 1; [Ag(PPh2(4-MeC6H4)-kappa P)(2)-mu-SCN-kappa S-2:N;kappa N-2:S](2) 2; [Ag(PPh2(4-NMe2C6H4)-kappa P}(2)mu-SCN-kappa S-2:N;kappa N-2:S](2) 3, as well as [Ag(PPh3-kappa P)(2)-mu-SCN-kappa S-2:N;kappa N-2:S](2) 4, were evaluated on a malignant SNO cell line for anticancer activity. The cytotoxicity of the complexes was compared to that of complex 4 and other silver(I) phosphine complexes. After a 24 h exposure of the complexes, the mode of cell death was determined by morphological studies of the cells under a microscope. An alamarBlue (R) viability assay was used to evaluate the toxicity of these complexes. All the complexes showed high toxicity at a 10 mu M treatment (silver concentration), compared to the untreated, vehicle and apoptotic (cisplatin) control. Morphological studies suggest an apoptotic mode of cell death. (C) 2016 Elsevier B.V. All rights reserved.
