4-Methylumbelliferyl-2-acetamido-2-deoxy-β-D-Glucopyranoside is a fluorogenic substrate for β-hexosaminidases that releases fluorescent 4-methylumbelliferone upon enzymatic cleavage, enabling sensitive quantification of enzyme activity across pH-dependent excitation and emission ranges, and is extensively used in clinical and research assays for GM2 gangliosidoses such as Tay-Sachs disease.

| Description | 4-Methylumbelliferyl-2-acetamido-2-deoxy-β-D-Glucopyranoside is a fluorogenic substrate for β-hexosaminidases that releases fluorescent 4-methylumbelliferone upon enzymatic cleavage, enabling sensitive quantification of enzyme activity across pH-dependent excitation and emission ranges, and is extensively used in clinical and research assays for GM2 gangliosidoses such as Tay-Sachs disease. |
| In vitro | Method: Enzymatic assays using 4-Methylumbelliferyl-2-acetamido-2-deoxy-β-D-Glucopyranoside as substrate were employed to screen inhibitors against the N-terminal fragment of O-GlcNAcase (nOGA). Result: Compound 4 selectively inhibited nOGA with a Ki of 48 μM, showing 15-fold selectivity over full-length OGA and 10-fold selectivity over lysosomal hexosaminidase[1]. |
