4-Methylumbelliferyl-α-D-Glucopyranoside (Synonyms:4-甲基伞形酮-ALPHA-D-葡萄糖苷; 4-Methylumbelliferyl-α-D-Glucose; 4-Methylumbelliferyl-α-D-Glucoside; 4-MU-α-D-Glucopyranoside)
目录号 : KCM12039 CAS No. : 17833-43-1 纯度 : ≥95%
4-Methylumbelliferyl-α-D-glucopyranoside is a fluorogenic substrate for α-glucosidase. 4-Methylumbelliferyl-α-D-glucopyranoside is cleaved by α-glucosidase to release the fluorescent moiety 4-methylumbelliferyl (4-MU). 4-MU fluorescence is pH-dependent with excitation maxima of 320 and 360 nm at low (1.97-6.72) and high pH (7.12-10.3), respectively, and an emission maximum ranging from 445 to 455 nm, increasing as pH decreases. 4-Methylumbelliferyl-α-D-glucopyranoside has been used to quantify α-glucosidase activity in infant blood spot samples as a biomarker of Fabry and Pompe diseases, lysosomal storage disorders characterized by a deficiency in the enzyme.

4-Methylumbelliferyl-α-D-Glucopyranoside is a fluorescent substrate for α-glucosidase, which releases the fluorescent moiety 4-methylumbelliferyl (4-MU) upon cleavage. 4-MU has pH-dependent fluorescence excitation activity, with excitation wavelengths of 320 nm at low pH (1.97-6.72) and 360 nm at high pH (7.12-10.3), respectively. The emission wavelength of 4-Methylumbelliferyl-α-D-Glucopyranoside increases with decreasing pH, ranging from 445-455 nm. 4-Methylumbelliferyl-α-D-Glucopyranoside can be used as a biomarker for Fabry and Pompe diseases to quantify α-glucosidase activity in infant blood spot samples.
