A Effect of compounds 1 (filled inverted triangle), 2 (open circle), 3 (filled square), 5 (open triangle), and 7 (filled circle) on α-glucosidase activities and hydrolysis of p-nitrophenyl-α-D-glucopyranoside. B Catalytic activity of α-glucosidase as a function of enzyme concentration at different concentrations of CS (filled circle 0 μM; open circle 5 μM; filled inverted triangle 10 μM; open triangle 20 μM). C Lineweaver–Burk plots for inhibition by CS. D Dixon plot for inhibition by CS
