    STRUCTURAL AND MOLECULAR DOCKING STUDIES OF BIOLOGICALLY ACTIVE MERCAPTOPYRIMIDINE SCHIFF BASES
    (Elsevier, 2017-01-05) JoneKirubavathy S; Velmurugan R; Karvembu R; Bhuvanesh N S P; Enoch I V M N; MosaeSelvakumar P; Premnath D; Chitra S
    Novel Schiff bases derived from the treatment of mercapto-diamino pyrimidine with two different aldehydes are characterized using elemental analysis, single crystal X-ray diffraction and 1H NMR spectroscopy. The pharmacological action of the synthesized compounds viz., antimicrobial, anticancer and antitubercular activities is studied. The Schiff bases show a very good activity against various test pathogens. DNA and β-CD binding interactions of the compounds are studied using UV–Visible absorption and fluorescence spectral measurements. The binding constants of the compounds towards β-CD are in the order of 103 to 104. Molecular docking is done using MOE program on the 3D structure of the enzymes, viz., human thymidylate synthase complexed with dump and raltitrex, candida albicans N-myristoyltransferasepeptidic inhibitor, catalytic domain of protein kinase pKnb from mycobacterium tuberculosis in complex with mitoxantrone, pare, topoisomerase atpase inhibitor, E. coli and lactobacillus casdihydrofolatereductase. The MIC/IC50 values of the Schiff bases are compared with the glide scores from the molecular docking studies. The number of hydrogen bonding interactions between the Schiff bases and amino acid residues are also reported.

    SYNTHESIS, CHARACTERIZATION, SINGLE-CRYSTAL XRD, AND BIOLOGICAL EVALUATION OF NICKEL(II) SALEN SULFADIAZINE COMPLEX
    (Synthesis and Reactivity in Inorganic, Metal-Organic, and Nano-Metal Chemistry, Taylor and Francis, 2016) Jone Kirubavathy S; Velmurugan R; Tamilarasan B; Karvembu R; Bhuvanesh N S P; Chitra S
    Nickel(II) Salen sulfadiazine complex was prepared and characterised by the spectral studies such as FT-IR, UV-Vis and NMR, and single-crystal XRD. The nickel(II) complex was screened for in vitro antimicrobial activities against various test organisms Aeromonashydrophila, Serratiamarcescens, Bacillus licheniform, Pseudomonas aeruginosa, Acinetobacterbaumanii, Aspergillusniger, and Candida albicans by the well diffusion method and in vitro anticancer activity against the human breast cancer cell line HeLa. The NiO obtained by the thermal decomposition of Ni (salen) sulfadiazine complex was characterised using TEM images and their SAED pattern

    SYNTHESIS, STRUCTURE, AND PHARMACOLOGICAL EVALUATION OF CO(III) COMPLEX CONTAINING TRIDENTATE SCHIFF BASE LIGAND
    (Springer, 2015-05-07) JoneKirubavathy S; Velmurugan R; Karvembu R; Bhuvanesh N S P; Parameswari K; Chitra S
    A Co(III) Schiff base complex with the formula [Co(L)2]Cl • H2O (I) (L = monoanionic tridentate Schiff base ligand derived from salicylaldehyde and ethylene diamine) has been synthesized and characterized by elemental analysis and spectroscopic techniques. The structure of I was confirmed by single crystal X-ray diffraction studies (CIF file CCDC no. 1009967), which showed the presence of two Schiff base molecules in an octahedral fashion. The complex has been screened for its in vitro antibacterial and anticancer activities. Complex I was found to be more active in anti-microbial and anti-cancer activity than the ligand.
