  Synthesis, structural characterization, fluorescence, antimicrobial, antioxidant and DNA cleavage studies of Cu(II) complexes of formyl chromone Schiff bases

  摘要：

  Cu(II) complexes have been synthesized from different Schiff bases, such as 3-((2-hydroxy phenylimino)methyl)-4H-chromen-4-one (HL1), 2((4-oxo-4H-chromen-3-yl)methylneamino) benzoicacid (HL2), 3((3-hydroxypyridin-2-ylimino)methyl)-4H-chromen-4-one (HL3) and 3((2-mercaptophenylimino)methyl)-4H-chromen-4-one (HL4). The complexes were characterized by analytical, molar conductance, IR, electronic, magnetic, ESR, thermal, powder XRD and SEM studies. The analytical data reveal that metal to ligand molar ratio is 1:2 in all the complexes. Molar conductivity data indicates that all the Cu(II) complexes are neutral. On the basis of magnetic and electronic spectral data, distorted octahedral geometry is proposed for all the Cu(II) complexes. Thermal behaviour of the synthesized complexes illustrates the presence of lattice water molecules in the complexes. X-ray diffraction studies reveal that all the ligands and their Cu(II) complexes have triclinic system with different unit cell parameters. Antimicrobial, antioxidant and DNA cleavage activities indicate that metal complexes exhibited greater activity as compared with ligands. (C) 2012 Elsevier B.V. All rights reserved.

  3-Formylchromone (1), 3-methyl-7-hydroxychromone (2) and Schiff bases of 3-formylchromone 3-19 have been synthesized and their anti-thymidine phosphorylase inhibitory activity was evaluated. Compounds 1-19 showed a varying degree of thymidine phosphorylase inhibition with IC50 values 19.77 +/- 3.25 to 480.21 +/- 2.34 mu M. Their activity was compared with the standard 7-deazaxanthine (IC50 = 39.28 +/- 0.76 mu M). Compound 12 showed an excellent thymidine phosphorylase inhibitory activity with an IC50 value of 19.77 +/- 3.25 mu M, better than the standard. Compound 4 also showed an excellent inhibitory activity (IC50 = 40.29 +/- 4.56 mu M). The parent 3-formylchromone (1) and 3-methyl-7-hydroxychromone (2) were found to be inactive. The structures of the compounds were elucidated by using spectroscopic techniques, including H-1 NMR, EI MS, IR, UV and elemental analysis. (C) 2009 Elsevier Ltd. All rights reserved.
