N,N '-bis(aniline)glyoxime (H2L, 1) has been prepared from aniline and (E,E)-dichloroglyoxime (DCGO) or (E,E)-dibromoglyoxime (DBGO). The reaction of N,N '-bis(aniline)glyoxime (H2L, 1) with solution of PtCl2 in dimethylsulfoxide produced brown-colored bis(E,E-dioximato)platinum(II) complex {[(E,E)-Pt(HL)(2)]} (1a) featuring N-chelating ligand. The crystal structure of this complex has been identified by X-ray diffraction on a single-crystal. In vitro assay of proliferation, cell death, DNA-damage and cell uptake activities of 1 and 1a were tested in HCC cell lines, SNU-182 and HUH-7. 1a has an anti-proliferative effect in HCC cells, however, 1 did not. Furthermore, the cellular uptake of 1a was relatively high compared to cisplatin cellular platinum levels. Compatible with proliferation and cellular uptake results, treatment with 1a caused DNA-damage and subsequent apoptosis in both HCC cell lines.
