Antiproliferative activity of platinum(II) complexes containing triphenylphosphine: Correlation between structure and biological activity

Add time:07/23/2019    Source:sciencedirect.com

A series of neutral complexes of platinum(II) of general formula [PtCl2L(PPh3)] [L = Et2NC(Me)NH, SOMe2, CO, Et2NH, (HOCH2CH2)2NH, Bz2NH, N-morpholine] was prepared starting from suitable precursors. The syntheses and spectroscopic characterizations of the two new complexes trans-[PtCl2(N-morpholine)(PPh3)] and cis-[PtCl2(SOMe2)(PPh3)] are described as well as their X-ray structures. The antiproliferative activity of all the available compounds was tested in vitro against HeLa, H460 and A549 human tumor cell lines. A brief discussion regarding the structure–activity correlation is presented.
