Piperidine, 1-methyl-4,4-bis[(9Z,12Z)-9,12-octadecadien-1-yloxy]- Usage And Synthesis

Uses

YSK 05 is a pH-sensitive cationic lipid. YSK 05 improves the intracellular trafficking of non-viral vectors. YSK 05-MEND shows significantly good gene silencing activity and hemolytic activity. YSK 05 overcomes the suppression of endosomal escape by PEGylation. YSK 05 effectively enhances siRNA delivery both in vitro and in vivo[1].

Biological Activity

YSK05 is an ionizable amino lipid (apparent pKa = ~6.5) that has been used in combination with other lipids in the formation of liposomes and lipid nanoparticles (LNPs).1,2,3 Administration of cyclic di-GMP in YSK05-containing liposomes increases serum levels of IFN-β, IFN-γ, IL-6, and TNF-α and activates natural killer (NK) cells in mice, as well as decreases lung metastasis in a B16/F10 murine melanoma model of metastasis.2 Intravenous administration of factor VII siRNA in YSK05-containing LNPs reduces factor VII activity in isolated mouse plasma.3
