Synthesis and 2D H-bonded Cd（ Ⅱ ） Network Structure of [Cd（C10H15N3）Cl2]

1 INTRODUCTION Transition metal Schiff base complexes have been extensively studied in the past two decades for their various crystallographic features, enzymatic reactions, steric effects[1～4], catalysis and magnetic properties[5, 6] as well as their important role in organisms[7, 8]. Most of these first-row materials are biologically essential with a number of their complexes showing bioactivities[9, 10]. Herein we describe the synthesis and X-ray structure of the cadmium (Ⅱ) compl…     

多柔比星稀土配合物与人血清白蛋白相互作用的研究

运用荧光光谱法研究了多柔比星稀土配合物(ADM-M)与人血清白蛋白(HSA)的相互作用.结果表明:多柔比星稀土配合物对HSA的荧光有较强的猝灭作用,其荧光猝灭为混合猝灭过程.求得多柔比星稀土配合物与HSA的结合常数、结合位点数.由热力学参数确定了多柔比星稀土配合物与HSA的作用力类型.同时用同步荧光光谱法考察了多柔比星...     

多柔比星稀土金属离子配合物与DNA相互作用的研究

用紫外分光光度法和荧光光谱法研究了多柔比星( Adriamycin,ADM)稀土金属离子配合物(ADM-M)与DNA的相互作用.结果发现,在pH=7.0时,ADM与Eu3+、yb3+能形成稳定配合物,该配合物可使DNA的最大吸收产生明显的减色效应及红移,并能够竞争置换溴化乙锭(EB)与DNA的结合点.KI猝灭试验发现D...
