7-[[4-O-(6-Deoxy-α-L-galactopyranosyl)-β-D-galactopyranosyl]oxy]-4-methyl-2H-1-benzopyran-2-one

Description:

The chemical substance known as "7-[[4-O-(6-Deoxy-α-L-galactopyranosyl)-β-D-galactopyranosyl]oxy]-4-methyl-2H-1-benzopyran-2-one," with the CAS number 383160-15-4, is a flavonoid glycoside. This compound features a benzopyran backbone, which is characteristic of flavonoids, and is substituted with multiple sugar moieties, specifically a 6-deoxy-α-L-galactopyranosyl group and a β-D-galactopyranosyl group. These sugar attachments enhance its solubility and bioactivity. The presence of the methyl group at the 4-position of the benzopyran ring contributes to its structural diversity and potential biological activity. Flavonoid glycosides are known for their antioxidant properties and may exhibit various pharmacological effects, including anti-inflammatory and antimicrobial activities. The specific arrangement of the sugar units and the benzopyran structure may influence its interaction with biological systems, making it a subject of interest in medicinal chemistry and natural product research. Further studies would be necessary to elucidate its precise biological functions and potential applications.

4-Methylumbelliferyl 4-O-(α-L-fucopyranosyl)-β-D-galactopyranoside

CAS: 383160-15-4

4-Methylumbelliferyl 4-O-(alpha-L-fucopyranosyl)-beta-D-galactopyranoside is a fluorogenic substrate for alpha-L-fucosidase. After enzymatic cleaveage, free 4-methylumbelliferone (also known as hymecromone) is released, exhibiting blue fluorescence upon excitation with UV light. The strongest fluorescence of 4-methylumbelliferone requires deprotonation of the hydroxyl group (thus requires alkaline pH), with a maximal fluorescence intensity obtained with excitation at 350 to 370 nm and emission at 440 to 470 nm. The use of 4-methylumbelliferyl 4-O-(alpha-L-fucopyranosyl)-beta-D-galactopyranosideas a substrate for measuring the alpha-L-fucosidase activity is used for fucosidosis diagnosis and in screening studies of glycoprotein metabolism disorders.
