Neu5Ac2-α-PNP (CAS 123549-14-4)

Neu5Ac2-α-PNP, a synthetic derivative of sialic acid, plays a crucial role in glycobiology research due to its ability to mimic sialic acid residues found on glycoproteins and glycolipids. Its chemical structure consists of a neuraminic acid moiety linked to a para-nitrophenyl (PNP) aglycone via an α-glycosidic bond. Researchers utilize this compound as a substrate for sialidases, enzymes involved in the hydrolysis of sialic acid residues from glycoconjugates. By monitoring the enzymatic cleavage of Neu5Ac2-α-PNP, scientists can explain the substrate specificity, kinetics, and catalytic mechanisms of sialidases, contributing to a deeper understanding of sialic acid metabolism in various biological contexts. Moreover, Neu5Ac2-α-PNP serves as a valuable tool in the development of high-throughput screening assays for sialidase inhibitors, facilitating drug discovery efforts targeting sialidase-mediated pathologies such as viral infections and cancer metastasis. Its versatility and reliability make it an indispensable component in glycobiology research, enabling investigations into the role of sialic acid biology in health and disease.
