Used primarily in biochemical research to study glycosphingolipid metabolism, this compound acts as a potent inhibitor of glucosylceramide synthase. By blocking this enzyme, it helps in understanding the role of glycosphingolipids in cell function and disease. It is particularly valuable in cancer research, where altered glycosphingolipid expression is often observed. Additionally, it aids in exploring potential therapeutic strategies for diseases like Gaucher's disease, where glycosphingolipid accumulation is a key issue. Its application extends to neuroscience, where it helps in studying the impact of glycosphingolipids on neuronal development and function.
