Synthesis, structure and in vitro cytotoxicity of platinum(II) complexes containing eugenol and a quinolin-8-ol-derived chelator

C. Nguyen Thi Thanh, M. Truong Thi Cam, T. Pham Van, L. Nguyen, M. Nguyen Ha and L. Van Meervelt

The synthesis of potassium (η²-4-allyl-2-methoxyphenol)trichloridoplatinate(II), K[PtCl₃(C₁₀H₁₂O₂)], (1), starting from Zeise's salt and Ocimum sanctum L. oil has been optimized. Starting from (1), three new platinum(II) complexes, namely (η²-4-allyl-2-methoxyphenol)chlorido(2-methylquinolin-8-olato-κ²N,O)platinum(II), (2), (η²-4-allyl-2-methoxyphenol)chlorido(5-nitroquinolin-8-olato-κ²N,O)platinum(II), (3), and (η²-4-allyl-2-methoxyphenol)chlorido(5,7-dichloroquinolin-8-olato-κ²N,O)platinum(II), [Pt(C₉H₄Cl₂NO)Cl(C₁₀H₁₂O₂)], (4), containing eugenol and a quinolin-8-ol derivative (R-OQ), have been synthesized and characterized by elemental analyses, MS, IR, ¹H NMR and NOESY spectra. For (1) and (4), single-crystal X-ray diffraction studies were also carried out. Complexes (2)–(4) show good inhibiting abilities on three human cancer cell lines, i.e. KB, Hep-G2 and LU, with IC₅₀ values of 1.42–17.8 µM. Complex (3) gives an impressively high activity against KB, Hep-G2, LU and MCF-7, with IC₅₀ values of 1.42–4.91 µM, which are much lower than those of cisplatin and some other platinum(II) complexes.

Keywords: platinum(II) complexes; crystal structure; eugenol; quinolin-8-ol derivatives; cytotoxicity.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
