摘要: 研究了不同酸度条件下,环丙沙星(CPFX)与牛血清白蛋白(BSA)间的相互作用,讨论了药物对BSA构象的影响,证实了二者间相互作用为单一的动态猝灭过程,求出了猝灭常数,并依据能量转移理论确定了药物与蛋白的最近距离.

Abstract: In this paper, the study of the reaction between Ciprofloxacin(CPFX) and bovine serum albumin(BSA) at different pHis reported. The conformational change of BSA due to the addition of CPFX is discussed. It is proved that only dynamic quenching exits between CPFX and BSA. Quenching constant is obtained and the distance between CPFX and BSA is determined according to the theory of energy transfer.

Key words: Ciprofloxacin, Bovine serum albumin, Fluorescence quenching
