2,7-二(苄胺酰乙氧基)萘稀土苦味酸配合物的合成、表征及其与DNA的作用
Synthesis, Characterization and DNA-Binding of Rare Earth Picorate Complexes with 2,7-Bis(Benzylamine carbonyl ethoxy) Naphthaedi
摘要
Abstract
2,7-Bis(benzylamine carbonyl ethoxy) naphthaedi (L) and its rare earth picorate complexes [RE(pic)3]L2(RE = Y,La,Eu,Tb) were synthesized and characterized by H NMR ,IR spectra,elemental analysis and molar conductivity.The complexation with ct-DNA was studied by spectrometry,cyclic voltammetry and,viscosity measurements in Tris-HCl buffer solution ( pH = 7.20 ) ,and the interaction strength was La(Ⅲ) >Tb(Ⅲ) >Y(Ⅲ) >Eu(Ⅲ).关键词
