3-O-tert-Butyldimethylsilyl-D-erythro-sphingosylphosphorylcholine (CAS 168411-99-2)

3-O-tert-Butyldimethylsilyl-D-erythro-sphingosylphosphorylcholine, with CAS number 168411-99-2, is a chemically modified sphingolipid. This compound is particularly notable for its tert-butyldimethylsilyl (TBDMS) protective group attached at the 3-oxygen of the sphingosine backbone. The presence of the TBDMS group is crucial as it makes the molecule more resistant to chemical breakdown and reactive conditions, thereby stabilizing the sphingosine component, which is sensitive to hydrolysis and oxidation. This stabilization is particularly useful in synthetic chemistry and biochemistry research, where the molecule is employed to study the structure, function, and synthesis of more complex sphingolipids. The protective group allows researchers to manipulate the molecule without altering the integrity of the sphingosine base, facilitating the exploration of biochemical pathways involving sphingolipids and their metabolites. In lipidomics, this compound aids in understanding the role of sphingosine derivatives in cellular signaling and membrane structure. Researchers use this derivative to trace the incorporation of sphingosine into cellular mechanisms and to dissect the interaction of sphingolipids with other biomolecules in the cell, thereby providing insights into the fundamental roles of these complex lipids in cellular physiology and the mechanism of action within various lipid-driven pathways.
