Boc-Pro-OMe (Boc-L-proline methyl ester) is a lipid compound utilized in liposome preparation. Liposomes consist of concentric phospholipid bilayer vesicles, which serve as vital components in constructing drug delivery systems for anticancer and anti-infection applications. These systems effectively encapsulate high-polarity water-soluble payloads within the internal aqueous space of the liposome, while lipophilic payloads are integrated into and become part of the lipid bilayer. This compound is particularly effective for delivering antisense oligonucleotides, addressing issues of low cellular uptake and rapid bodily excretion.
