    INVESTIGATION OF DNA BINDING AND CLEAVAGE ACTIVITIES OF BORON COMPLEXES IN THE PRESENCE OF HYDROGEN PEROXIDE
    (Univ Babes-Bolyai, 2014) Devrim, Alparslan Kadir; Arslantas, Ali; Sudagidan, Mert; Kose, Dursun Ali; Karan, Birgul
    Magnesium [di(hydroxy)mono(citratoborate)]dihydrate (Mg[B(Cit)(OH)(2)](2)center dot 2H2O), Lithium [di(hydroxy)mono(citratoborate)]hydrate Li[B(Cit)(OH)(2)]center dot H2O, Sodium [di(hydroxy)mono(salicylato) borate)hydrate Na[B(Sal)(OH)(2)]center dot H2O and Magnesium[bis(salicylatoborate)]decahydrate Mg[B(Sal)(2)](2)center dot 10H(2)O) complexes have been synthesized and characterized. The cattle genomic DNA (CG-DNA) interaction of the complexes was studied by spectroscopic methods, viscosity, and electrophoresis measurements. The complexes partially intercalated to CG-DNA. Furthermore, DNA cleavage activity of these complexes was also investigated using agarose gel electrophoresis and the complexes show moderate ability of cleavage to the DNA.

    Tetraaquabis(orotato-?O)cobalt(II) dihydrate
    (Wiley-Blackwell, 2010) Ay, Ahmet Nedim; Kose, Dursun Ali; Tercan, Baris; Yuksel, Fatma; Hokelek, Tuncer
    In the title Co(II) complex, [Co(C(5)H(3)N(2)O(4))(2)(H(2)O)(4)]center dot 2H(2)O,the CoII ion is located on an inversion center and is coordinated by two orotate (2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate) anions and four water molecules in a slightly distorted octahedral geometry. The dihedral angle between the carboxylate group and the attached orotate ring is 1.2 (3)degrees. In the crystal structure, intermolecular O-H center dot center dot center dot O, N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds link the molecules into a three-dimensional network. pi-pi contacts between the orotate rings [centroid-centroid distances = 3.439 (2) and 3.438 (2) angstrom] further stabilize the structure.
