9(10)-Nitrooleate（NOA）is an endogenous nitrated fatty acid that functions as a highly efficient bioactive molecule. Its primary role is the specific inhibition of the STING protein, a key inflammatory signaling sensor within cells. When STING is aberrantly activated, it can trigger a severe inflammatory response, leading to cellular damage.Mechanistically, NOA acts as an electrophile, capable of covalently modifying specific cysteine residues on the STING protein, thereby effectively blocking its ability to activate downstream signaling pathways. This inhibitory action establishes NOA as a potent endogenous anti-inflammatory agent. In practical application, loading NOA into delivery systems, such as lipid nanoparticles, equips them with an intrinsic "molecular fire extinguisher." It significantly mitigates the acute inflammatory response triggered by delivered cargo, effectively transforming otherwise toxic delivery vehicles into safe platforms. The core value of NOA lies in its ability to provide exceptional safety without compromising the functional expression of therapeutic payloads, offering a crucial safeguard for achieving long-term treatments.

The AA15 lipid, an amino acid-derived ionizable lipid, integrates a carboxylic acid-containing headgroup and biodegradable branched ester tails (R2) to enhance mRNA delivery. Optimized as AA15V LNP, it exhibits a hydrodynamic diameter of 102.3 ± 4.1 nm, low polydispersity (PDI <0.15), and slightly positive zeta potential (+4–6 mV), enabling efficient tumor-targeted delivery. With a pKa ~6.1–6.4, AA15V ensures protonation in acidic endosomes, promoting mRNA release. It achieves >85% mRNA encapsulation efficiency, critical for stable saRNA delivery. In vitro, AA15V LNP-sSE-SCTs induced sustained SE-SCT expression (69% H-2Kb+β2m+ B16F10 cells at 72 h), outperforming mRNA formulations. In vivo, a single intratumoral dose of AA15V LNP-sSE-SCTs suppressed tumor growth by 22-fold in vaccinated mice, synergizing with checkpoint inhibitors (anti-PD-1/CTLA-4) for complete regression in 28.6% of lymphoma models. Ex vivo, AA15V enabled SE-SCT expression in human glioblastoma (7.1% CD45− cells) and lung cancer samples (5.8–8.7%), underscoring clinical potential. Key data: pKa ~6.3; encapsulation: 85–89%; zeta: +4–6 mV; size: 102.3 ± 4.1 nm.

iChol15-C4A2 is a groundbreaking ionizable cholesteryl lipid, expertly designed to overcome the primary challenge of liver-centric accumulation in mRNA therapeutics. Its innovative "two-in-one" structure seamlessly integrates cholesterol with an ionizable headgroup, enabling the formation of stable, three-component Lipid Nanoparticles (Tc-LNPs).The key advantage of Tc-LNPs formulated with iChol15-CA2 is their significantly reduced adsorption of Apolipoprotein E (ApoE).This unique property directly attenuates ApoE/LDLR-mediated uptake by liver cells, dramatically shifting biodistribution toward extrahepatic tissues. Peer-validated research demonstrates a remarkable 20-50 fold increase in the spleen-to-liver mRNA expression ratio compared to standard LNPs like ALC-0315, unlocking unparalleled potential for targeting the immune system. Beyond its superior targeting capability, iChol15-C4A2 ensures high mRNA encapsulation efficiency, excellent colloidal stability, and proven biocompatibility. It offers a powerful, off-the-shelf solution to advance next-generation mRNA applications, from innovative vaccines and cancer immunotherapies to treatments for splenic disorders. Discover how iChol15-C4A2 can transform your delivery platform.
