Fig. 3. Fluorescence titration of compound 14 into a 1 μM solution of α-synuclein in PBS buffer at pH 7.4 (squares) and into PBS 1× buffer with no protein (circles) at 298 K. The spectra were recorded using 355 nm as excitation wavelength and using the emission spectra at 425 nm. The lines show the best fit to eqn (1)–(3).
