4-Nitrophenyl3-O-(2, 3, 4, 6-tetra-O-acetyl-a-D-mannopyranosyl)-4, 6-O-cyclohexylidene-b-D-mannopyranoside

4-Nitrophenyl 3-O-(2,3,4,6-tetra-O-acetyl-a-D-mannopyranosyl)-4,6-O-cyclohexylidene-b-D-mannopyranoside 4-Nitrophenyl 3-O-(2,3,4,6-tetra-O-acetyl-a-D-mannopyranosyl)-4,6-O-cyclohexylidene-b-D-mannopyranoside is a chromogenic pNP enzyme substrate, which features a cyclohexylidene-protected mannopyranosyl core. Upon enzymatic hydrolysis by glycosidases or other related enzymes, it releases a yellow-colored product, 4-nitrophenol, that can be easily detected spectrophotometrically. This substrate is useful for studying enzyme specificity, kinetics, and inhibition, as well as for the screening of enzyme inhibitors, the identification of glycosidase-producing organisms, and the development of new analytical methods.
