Fig. 3From: A novel BACE inhibitor isolated from Eisenia bicyclis exhibits neuroprotective activity against β-amyloid toxicitya Lineweaver-Burk plots for the inhibition of β-secretase in the presence of FF. Concentrations of FF for the curves were 50, 100, and 200 μg/mL, using the substrate as the control. b Dixon plots for the inhibition of β-secretase by FF in the presence of different concentrations of the substrate: 500 nM (black circle), 750 nM (white circle), 1000 nM (white square), and 1500 nM (black square)Back to article page
