IUPAC Name: N-((S)-1-(((S)-1-(((S)-5-guanidino-1-((4-methyl-2-oxo-2H-chromen-7-yl)amino)-1-oxopentan-2-yl)amino)-3-methyl-1-oxobutan-2-yl)amino)-1-oxo-3-phenylpropan-2-yl)benzamide
InChIKey: PAMBMLAUEGWIPT-DZQJYWQESA-N
SMILES: CC(C1=CC=C(O[C@@H]2O[C@@H]([C@@H]([C@@H]([C@H]2O)O)O)COS(=O)(O)=O)C=C1O3)=CC3=O
Biological Activity: 4-Methylumbelliferyl-β-D-galactopyranoside 6-sulfate is a fluorescent dye. 4-Methylumbelliferyl-β-D-galactopyranoside 6-sulfate undergoes desulphation by galactose-6-sulphate sulphatase to form 4-methylumbelliferyl-β-D-galactopyranoside, which is cleaved by β-galactosidase to release fluorescent 4-methylumbelliferone. 4-Methylumbelliferyl-β-D-galactopyranoside 6-sulfate interacts with N-acetylgalactosamine-6-sulfate sulfatase (GALNS) via hydrogen bonds, electrostatic interactions, and steric interactions. 4-Methylumbelliferyl-β-D-galactopyranoside 6-sulfate serves as a substrate in assays measuring galactose-6-sulphate sulphatase and GALNS activity. 4-Methylumbelliferyl-β-D-galactopyranoside 6-sulfate can be used for the research of Morquio disease type A (mucopolysaccharidosis IV A)[1][2].
