Figure 4. Effects of site marker ligands on the intensity of induced CD of curcuminoids- HSA systems (A: Cur; B: Dmc; C: Bdmc).

Figure 4

CD displacement measurements were performed in 0.1-HCl buffer (pH 9.0 and 37°C). WF, PBZ and IDP were used as the site I marker ligands, whereas IBF, CAP and DZP were used as the site II marker ligands. The displacement experiments were performed by recording the CD value (at 427 nm) of a solution containing 25 µM curcuminoids and 50 µM HSA with displacer (site marker ligands)-to-curcuminoids molar ratio increasing from 0 to 6.0.
