title: Synthesis, spectroscopy and antiproliferative activity of cis- and trans-platinum(II) complexes with diethyl (pyridin-4-ylmethyl)phosphate. X-ray crystal structure of trans-Pt(II) complex.
abstract: Preparations of cis- and trans-platinum(II) complexes of diethyl (pyridin-4-ylmethyl)phosphate (4-pmOpe) have been described. These complexes were identified and characterized by far-IR, 1H NMR, 13C NMR, 31P NMR and 195Pt NMR and microanalyses. The crystal and molecular structure of trans-platinum(II) complex i.e., trans-[PtCl2(4-pmOpe)2] was determined by the X-ray diffraction. Novel complexes were assayed for their potential antiproliferative effect against HT 29 (colorectal adenocarcinoma) and A 549 (non-small cell lung cancer) cell lines as well as normal human peripheral blood lymphocytes. The results obtained indicate that novel analogues of cis-diamminedichloroplatinum(II) cause inhibition of cells growth which suggest that they could be chemotherapeutic drugs in the future.
