Study on the interaction of silver(I) complex with bovine serum albumin by spectroscopic techniques.

The interaction of silver(I) complex, [Ag (2,9-dimethyl-1,10-phenanthroline)(2)](NO(3))·H(2)O, and bovine serum albumin (BSA) was investigated by spectrophotometry, spectrofluorimetry and circular dichroism (CD) techniques. The experimental results indicated that the quenching mechanism of BSA by the complex was a static procedure. Various binding parameters were evaluated.

DNA binding and gel electrophoresis studies of a new silver(I) complex containing 2,9-dimethyl-1,10-phenanthroline ligands.

The silver(I) complex, [Ag(2,9-dimethyl-1,10-phenanthroline)(2)](NO(3)) · H(2)O, has been synthesized and characterized by physicochemical and spectroscopic methods. The binding interactions of this complex with calf thymus DNA (CT-DNA) were investigated using emission, absorption, circular dichroism, viscosity measurements, and gel electrophoresis studies. The calculated binding constant, K(b), obtained from UV-vis absorption studies was 5.
