| | In Vitro Fucosidase Inhibition |
| Description: | Fucosidase inhibition was assessed by preparing a reaction mixture of 50 mM phosphate-citrate pH 4.5, 5 mM MgCl2, 640 nM 4-methylumbelliferyl-alpha-L-fucopyranoside (4MU-FUC), 1 ng/mL rhFUCA1 (R&D Systems), and compound II, III, or IV. Reactions (100 μL) were incubated at 37° C. for 30 minutes and then quenched with the same volume of 600 mM citrate-carbonate buffer, pH 9. Fluorescence was measured by excitation at 360 nm and emission at 450 nm. |
