Abstract:
Copper complexes of molecular formulae, [CuL(1)(OAc)], [CuL(2)(H(2)O)], [CuL(3)(H(2)O)], [CuL(4)(H(2)O)], [CuL(5)(H(2)O)] where L(1)-L(5) represents Schiff base ligands [by the condensation of 3-hydroxyflavone with 4-aminoantipyrine (L(1))/o-aminophenol (L(2))/o-aminobenzoic acid (L(3))/o-aminothiazole (L(4))/thiosemicarbazide (L(5))], have been prepared. They were characterized using analytical and spectral techniques. The DNA binding properties of copper complexes were studied using electronic absorption spectra and viscosity measurements. Superoxide dismutase and antioxidant activities of the copper complexes have also been studied. Furthermore, the copper complexes have been found to promote pUC18 DNA cleavage in the presence of oxidant. Anti-tuberculosis activity was also performed.
