W19-LNP
W19-LNP is a lipid nanoparticle formulated with a Ugi-reaction-derived ionizable lipid (W19). W19-LNP demonstrates highly selective mRNA delivery to the spleen in female BALB/c mice upon intravenous administration. W19-LNP can be used for the research of mRNA-based vaccine delivery, immune cell reprogramming, and gene-engineered cell preparation.

Biological Activity
W19-LNP (200 ng; 6 h) exhibit exceptional mRNA transfection efficiency in 16HBE and HepG2 cells[1].
W19-LNP (0.125-4.00 ng/µL; 24 h) show good in vitro safety in 16HBE cells, with relative cell viability remaining above 80%[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:BALB/c (female, eight-week-old)[1]
-
Dosage:0.2 mg/kg
-
Administration:i.v.; single dose
-
Result:Achieved high mRNA transfection potency.
Exhibited highly selective spleen targeting, with a proportion of splenic transfection (PST) of 95.4%.
-
Animal Model:BALB/c (female, six-week-old)[1]
-
Dosage:1 mg/kg
-
Administration:i.v.; single dose
-
Result:Showed no remarkable pathological alterations in major tissues: uniform myocardial fibers with distinct boundaries in heart, indistinct liver lobule boundaries without inflammatory cell infiltration in liver, evenly distributed red pulp with clear white pulp boundaries in spleen, no significant vascular abnormalities in lung, and evenly distributed glomeruli without inflammatory cell infiltration in kidney.
Revealed statistically significant increases in aspartate aminotransferase (AST) and blood urea nitrogen (BUN) compared to PBS controls, but all values remained within the normal safety range.
