4-METHYLUMBELLIFERYL SULFATE POTASSIUM SALT Chemical Properties,Usage,Production

Chemical Properties

Crystalline Solid

Uses

4-Methylumbelliferyl sulfate potassium salt is a fluorometric substrate for the determination of sulfatase. This substrate has been used in the discovery of tyrosine sulfotransferase inhibitors, particularly in P-selectin glycoprotein ligand-1 binding. This compound is virtually non-fluorescent until cleavage by sulfatase enzymes, then emits blue fluorescence (450 nm) with excitation at 360 nm. Use of this compound in high-throughput fluorescence based screening led to the discovery of several potent beta-arylsulfotransferase IV (beta-AST-IV) inhibitors.

Uses

Met-enkephalin analog found in opioid extracts of brain and adrenal chromaffin cells that is an artifact generated by trichloroacetic acid extraction. MUS is used as a fluorimetric substrate for arylsulphatase enzyme. Subsitution of the hydroxyl group of 4-Methylumbelliferyl sulfate potassium salt causes the excitation wavelength of the umbelliferone to shift to shorter values and also brings about a decrease in fluorescence. Fluorescence: max. Abs = 334 mm; max. Em. = 370 mm

Biological Activity

4-Methylumbelliferyl sulfate (4MUS) is capable of undergoing desulfation and involve in futile cycling with 4MU. It can be utilized to measure the arylsulfatase activity of several sulfatases.
