The fluorescence spectra a-c of α-glucosidase at different concentrations (0, 3.125, 6.25, 12.5, 25.0, and 50.0 μM for curves a → f, T = 37 °C, a For compound 1, b For compound 8, c For compound 2. (Inset) Areas under curves of fluorescence emission spectra for HNE are shown for compounds 1, 8, and 2, respectively. d The correlation curve between the inhibitory potencies (IC50s) and the Stern–Volmer constant (KSV)
