α-2,3-sialyltransferase-IN-1 is primarily used in biochemical research to study the function and inhibition of α-2,3-sialyltransferase enzymes. These enzymes are involved in the addition of sialic acid to glycoproteins and glycolipids, which plays a critical role in cell-cell interactions, immune response, and pathogen recognition. By inhibiting this enzyme, researchers can investigate its role in various biological processes, including cancer metastasis, inflammation, and viral infections. This compound is particularly valuable in developing therapeutic strategies targeting diseases where abnormal sialylation is a factor, such as certain cancers and autoimmune disorders. Additionally, it aids in understanding the molecular mechanisms underlying glycosylation pathways, contributing to advancements in glycobiology and drug development.
