4-Methylumbelliferyl 2,3,4,6-Tetra-O-acetyl-α-D-glucopyranoside (CAS 67945-53-3)

4-Methylumbelliferyl 2,3,4,6-tetra-O-acetyl-α-D-glucopyranoside is a fluorogenic substrate commonly employed in biochemical and enzymatic assays to detect and quantify the activity of various glycosidases. The mechanism of action involves the enzymatic hydrolysis of the glycosidic bond by glycosidases, resulting in the release of 4-methylumbelliferone (4-MU), a highly fluorescent compound. This substrate exhibits minimal background fluorescence in its unhydrolyzed form, but upon enzymatic cleavage, it produces a strong and easily detectable fluorescence signal, making it suitable for high-throughput screening and kinetic analysis of glycosidase activities. Researchers utilize this compound to study the properties and functions of glycosidases in various biological processes, including carbohydrate metabolism, lysosomal storage disorders, and microbial degradation of polysaccharides. Furthermore, 4-Methylumbelliferyl 2,3,4,6-tetra-O-acetyl-α-D-glucopyranoside serves as a valuable tool for investigating glycosidase inhibitors and modulators, facilitating the development of agents for glycosidase-related diseases. Its versatility, sensitivity, and ease of use make it a widely utilized substrate in glycobiology research, contributing to the understanding of glycosidase-mediated processes.
