Synthesis And Characterization Of The Copper(Ii) Complex With 2,2-Bis(1h,3h,5h)Pyrimidine-4, 6-Dione-1,2-Diiminoethane: Fluorescence Quenching Studies In Proteins
SYNTHESIS AND REACTIVITY IN INORGANIC AND METAL-ORGANIC CHEMISTRY(2003)
摘要
The new ligand 2,2-bis(1H,3H,5H)pyrimidine-4,6-dione-1,2-diiminoethane (H2SB) has been synthesized and characterized by elemental analyses, IR, NMR spectroscopy. Its copper complex has also been prepared and charaterized by. various physico-chemical methods. The reactivity of the 2,2-bis (1H,3H,5H)pyrimidine-4,6-dione- 1,2-diiminoethanecopper(II) complex towards protein has been studied spectrophotometrically. Affinity constants and binding capacity constants of protein with 2,2-bis(I H,3H,5H)pyrimidine-4,6-dione- 1,2-diiminoethanecopper(II) [Cu(SB)] (SB = doubly deprotonated Schiff base) have been calculated.
