The reversible binding of ethacrynic acid was characterized by a difference circular dichroism method. A 2/1 stoichiometry was determined for the [drug]/[HSA] (human serum albumin) complex. The reversible binding of ethacrynic acid to HSA determines direct competition with ligands that selectivity b

β¦ Synopsis
Multidimensional fluorescence-detected circular dichroism (FDCD) is used to investigate the binding of bilirubin to four mammalian serum albumins. It is shown that the complexes formed with the albumins have distinctly different FDCD spectra. The effect of the pH-dependent transition from basic to acidic conditions on the complexes is examined. The binding of warfarin to albumin is also presented to demonstrate the general analytical utility of the multidimensional FDCD measurement for biochemical analysis. o 1987 Academic FVSS, I~C.

## Abstract The binding mechanism of myricetin (Myr) to bovine serum albumin was investigated by using steadyβstate and timeβresolved fluorescence and circular dichroism. The results of the steadyβstate fluorescence quenching experiment indicate that it is a static quenching process (__C__~Myr~/__C
