Application

4-甲基伞形酮N-乙酰-β-D-氨基葡萄糖苷在酸性几丁质酶活性测定中用作荧光底物。它还用于测定水样滤液中β-N-乙酰己糖胺酶(NAGase)的总活性。

Biochem/physiol Actions

4-甲基伞形酮-N-乙酰-β-D-氨基葡萄糖苷(4-MUF-NAG)是一种用于氨基己糖苷酶的合成不带电荧光底物。它由几丁质单体（N-乙酰-β-D-氨基葡糖苷）和4-甲基伞形酮（7-氢氧基-4-甲基香豆素）(4-MUF)组成。4-MUF-NAG用于通过测定β-N-乙酰己糖胺酶(NAGase)活性来检测和估计真菌的生长。

A new fluorogenic substrate, 4-methylumbelliferyl beta-D-glucosaminide, was used for the assay of acetyl CoA:glucosaminide N-acetyltransferase in chorionic villi, cultured villus cells, and amniocytes. Optimal conditions for the assay and the ranges of enzyme activity were established for the various types

Temperature-jump relaxation methods have been used to study the binding kinetics of fluorescent 4-methylumbelliferyl glycosides of N-acetyl-beta-D-glucosamine and its beta (1 leads to 4)-linked di- and trisaccharides with wheat germ agglutinin. The mono- and disaccharide derivatives yielded biexponential progress curves.

This paper describes a comparison of the recently developed substrate 2-methoxy-4-(2'-nitrovinyl)-phenyl-2-acetamido-2-deoxy-beta-D-gluc opyranoside (MNP-GlcNAc) and the corresponding 4-methylumbelliferyl substrate (4-MU-GlcNAc) for the determination of urinary NAG. A good correlation (r = 0.977) was found between NAG activities in 366 urine samples
