摘要: 本文利用荧光猝灭技术和紫外可见分光光度法研究了黄芩苷和汉黄芩苷与人血清白蛋白的结合性质,由药物对血清白蛋白的荧光猝灭作用求出了其结合常数. 根据热力学参数,确定了结合力的性质. 并进一步研究了Zn2+, Mg2+, Al2+,和 Cu2+存在时对结合性质的影响. 不仅对于揭示体内药物动力学问题,指导临床合理用药具有一定意义,而且对于进行药物分子设计、开发新药等也具有重要指导意义.

Abstract: In this paper, the interactions of baicalin and wogonoside with human serum albumin (HSA) were studied by fluorescence quenching and ultraviolet-visible absorption spectrometry. The binding constants were obtained by fluorescence quenching of drug with serum albumin. The main acting binding forces of baicalin and wogonoside to serum albumins were hydrophobic force according to the thermodynamic parameters. The effects of metal ions, such as Zn2+, Mg2+, Al3+ and Cu2+on binding constants were also evaluated. It is not only valuable to reveal the pharmacokinetics, clinical therapy, but also have guiding significance for drug design and development of new drugs.
