ABSTRACT
The interaction between warfarin and bovine serum albumin (BSA) under pseudophysiological conditions was investigated by UV-Vis absorption spectrometry and spectrofluorimetry. The quenching mechanism of BSA by warfarin was discussed. It showed that the quenching process was a dynamic quenching, and the quenching constants were 6.05 x 10(4) L x mol(-1) at 16 degrees C and 6. 14 x 10(4) L x mol(-1) at 37 degrees C, separately. Based on the Förster theory of non-radiative energy transfer, the energy transfer efficiency and the distance of BSA to warfarin were calculated, which was 0.37 and 3.15 nm, respectively.
