Dimethyl-DL-2,3-distearoyloxypropyl(2-hydroxyethyl)ammonium acetate (CAS 13106-14-4)

Dimethyl-DL-2,3-distearoyloxypropyl(2-hydroxyethyl)ammonium acetate, a synthetic cationic lipid, is extensively used in research for studying lipid bilayers and gene delivery systems. This compound, known for its strong amphiphilic properties, is instrumental in the formation of liposomes and lipid nanoparticles. These structures are crucial for examining the biophysical properties of lipid bilayers, including membrane fluidity, stability, and permeability. By incorporating this lipid into model membrane systems, researchers can investigate how cationic lipids interact with other lipid species and proteins, influencing membrane organization and dynamics. In the field of gene delivery, Dimethyl-DL-2,3-distearoyloxypropyl(2-hydroxyethyl)ammonium acetate is used to create lipoplexes, which are complexes formed between cationic lipids and nucleic acids. These lipoplexes facilitate the encapsulation and delivery of genetic material into cells, providing a tool to study transfection efficiency and the mechanisms of cellular uptake and intracellular trafficking. The compound′s positive charge enables it to bind effectively with negatively charged nucleic acids, promoting cellular entry through endocytosis. Researchers also utilize this lipid to explore the effects of lipid composition on the transfection process, optimizing formulations for increased stability and efficiency. Current studies focus on its role in enhancing the delivery and expression of plasmid DNA, siRNA, and mRNA in various cell types. By understanding the interactions and mechanisms of this cationic lipid, scientists aim to advance the development of lipid-based delivery systems for research applications.
