(2S)-3-Keto sphinganine (d6:0) ((2S)-3-Keto-C6-dihydrosphingosine) hydrochloride is a lipid compound utilized in the preparation of liposomes. Liposomes, characterized by concentric phospholipid bilayer vesicles, are critical in constructing drug delivery systems for anti-cancer and anti-infection applications. They effectively encapsulate hydrophilic solutes within their aqueous interiors and incorporate lipophilic cargoes into their phospholipid bilayers, making them integral to the bilayer structure. This compound is particularly valuable in delivering antisense oligonucleotides, addressing challenges such as inefficient cellular uptake and rapid loss in the body.
