CD BioGlyco has a compound-rich natural product library, etc., to meet the needs of Glycosylation Inhibitor Development. Sialic acid is one of the most vital sugars in the human body after glucose. It plays a key role in intercellular recognition, adhesion, protein-lectin interaction, receptor binding, etc. Sialyltransferase (ST) mediates the synthesis of sialic acid-containing glycoconjugates. ST6Gal is a type of ST that adds α2,6-conjugated sialic acid to galactose residues of N-glycans. We provide ST6Gal inhibitor development services in multiple orientations. Our goal is to screen compounds from natural products or high throughput for high inhibitory activity even at high concentrations of ST6Gal substrates.

Different STs catalyze different chemical bonds and receptor substrates. Based on the differences in bond and receptor substrates, several types of ST inhibitors have been developed. Among them, transition state analogs have relatively good inhibitory activity. Based on the receptor specificity of ST6Gal, we screen, design, and synthesize transition-state analogs, dual-substrate analogs, donor analogs, and acceptor analogs that effectively inhibit ST6Gal based on CMP-Neu5Ac or acceptor oligosaccharides.
Natural products, including aromatic compounds, Flavonoids, Lithocholic Acid Analogs, etc., have a variety of biological activities such as antioxidant, anticancer and antibacterial. Their natural products have excellent biological activities and specific active skeletons and active groups, which are important resources for inhibitor development. Our natural product library contains a rich variety of compounds. Rare natural products, selected products, and natural product analogs are available, which fully meet the needs of ST6Gal inhibitor development.

Results: In this study, a series of uridine analogs were designed and synthesized by coupling hetaryl α-hydroxyphosphonates and coupling aryl with a 5'-amino-5'-deoxyuridine fragment. The design strategy for this class of compounds was to replace the phosphodiester junction with carbamate and cytidine with uridine. Five of these compounds were tested and found to exhibit inhibitory activity against recombinant human ST6Gal I. This study provides a new compound design idea for the development of ST inhibitors.
