摘要
The interation of caffeine and theophylline with bovine serum albumins has been studied by fluorescence spectroscopy. The results indicated that enoxacin could bind with BSA strongly at molar ratio 1 : 1 and the equilibrium constants were K-c = 1.673 X 10(4) L circle mol(-1) and K-t = 6.802 X 10(3) L circle mol(-1), respectively. Good linear Stern-Volmer lines were observed on the fluorescence of BSA quenched by enoxacin of different concentration, indicating that the combination reaction of enoxacin with BSA is a single static quenching process.
