Abstract:

Two di-2,4-dichlorobenzyltin complexes (C1, C2) have been synthesized from p-methoxybenzoyl hydrazide-2-ketobutyric acid or 2-thiophene hydrazide2-ketobutyric acid with di-2,4-dichlorobenzyltin dichloride, respectively. The properties and the crystal structures of the complexes C1 and C2 were characterized by Fourier transform infrared spectrometer (FTIR), nuclear magnetic resonance spectroscopy (NMR) and single crystal X-ray diffraction (SCXRD). Two complexes are all binuclear molecules containing a Sn2O2 four-membered ring. The central tin atom and the coordination atom form a hepta-coordinationed distorted pentagonal bipyramid configuration. The complexes C1 and C2 are stable under 120 ℃ in air, and exihibit good inhibitory effects on human non-small cell lung cancer (NCI-H460), human liver hepatocellular carcinoma (HepG2) and human breast adenocarcinoma (MCF-7) cancer cells cancer cells, but complex C1 is slightly better than complex C2. The interaction between two complexes and calf thymus DNA is intercalation, and the effect of complex C1 and DNA is slightly stronger than that of complex C2.
