LNPs comprised of 4-O10b1 and conjugated with the macrophage antibody F4/80 were able to delivery siRNA targeting TAK1 to RAW264.7 cells resulting in suppressed activation of NF-kB. Intranasal administration reduced lung injury in an influenza mouse model.

Lipid 35 is an novel ionizable lipid designed to enhance the delivery of mRNA to specific tissues, particularly the lungs.Lipid 35 demonstrates superior chemical stability, especially in storage conditions. This stability ensures that the lipid maintains its integrity over extended periods, making it ideal for long-term storage and large-scale production.Lipid 35 exhibits high transfection efficiency in various cell types, including nonimmune cells, endothelial cells, and epithelial cells. Lipid 35 has demonstrated excellent biocompatibility and safety in preclinical studies. It does not cause significant liver damage or adverse immune responses, making it a safer alternative for therapeutic applications.

L-608 is a novel ionizable amino lipid designed for formulating lipid nanoparticles (LNPs) to enable efficient subcutaneous (s.c.) delivery of mRNA therapeutics. Engineered to address inflammation associated with mRNA LNPs, L608 integrates seamlessly with steroid prodrugs, such as budesonide-C16 and budesonide-C18:1, to suppress local and systemic inflammatory responses while prolonging therapeutic protein expression. Preclinical studies demonstrate that L608 LNPs significantly reduce injection-site edema (>80% improvement) and lower systemic inflammatory markers (e.g., haptoglobin), while achieving 2–3× higher plasma AUC for proteins like hFGF21 compared to non-steroid LNPs.
