2-Mercaptoethyl 2-(Acetylamino)-2-deoxy-β-D-galactopyranoside (CAS 95074-13-8)

2-Mercaptoethyl 2-(Acetylamino)-2-deoxy-β-D-galactopyranoside is a thiol-modified derivative of N-acetylgalactosamine, serving as a versatile tool for glycoscience research due to its unique functional groups. The acetylamino modification mimics N-acetylgalactosamine, a common sugar residue in glycoproteins and glycolipids, providing researchers with a structurally relevant analog. The mercaptoethyl group acts as a reactive handle, allowing covalent attachment to gold surfaces, fluorescent tags, or solid supports. This facilitates the study of carbohydrate-protein interactions, enabling the formation of glycan microarrays or glyco-engineered surfaces. These platforms are used to profile the binding specificity of lectins and glycan-binding proteins, crucial for understanding cell recognition and signal transduction. Researchers leverage this compound in synthetic chemistry to produce neoglycoconjugates, expanding the toolkit for studying carbohydrate-mediated processes. Its incorporation into glycopolymers or nanoparticles aids in the exploration of multivalent binding interactions, revealing how structural variations influence glycan-protein recognition. Additionally, it supports the analysis of enzymatic specificity, particularly glycosyltransferases and glycosidases, by serving as a substrate analog. Overall, 2-Mercaptoethyl 2-(Acetylamino)-2-deoxy-β-D-galactopyranoside is invaluable for probing glycan-related pathways, advancing our comprehension of carbohydrate function in biological systems through synthetic and analytical approaches.
