6,6′-Trehalose Dioleate - CAS 338733-40-7

6,6′-Trehalose dioleate (6,6′-TDO) is a glycolipid extensively used for in vivo and in vitro mRNA delivery. This compound effectively encapsulates mRNA encoding hemagglutinin A (HA) from influenza A virus for use within lipid nanoparticles (LNPs), enhancing the secretion of Ifn-γ, Il-2, and Tnf-α from isolated murine spleen cells. When administered via intramuscular injection in mice, LNPs containing 6,6′-TDO predominantly accumulate in the liver and spleen. Unlike LNP formulations without 6,6′-TDO, those containing 6,6′-TDO do not reduce serum levels of blood urea nitrogen (BUN) or elevate levels of lactate dehydrogenase (LDH), troponin I, alanine aminotransferase (ALT), or aspartate aminotransferase (AST) . Additionally, these LNPs enhance the serum titers of IgG1 and IgG2a antibodies in mice.
