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.

Lipid 17 is a novel, highly potent ionizable lipid designed for mRNA delivery within lipid nanoparticles (LNPs) developed by AstraZeneca . Its structure features a secondary amine head group attached to a cyclic ether moiety (specifically, the 2-oxaspiro[3.3]heptan-6-amine head group). It possesses an asymmetric tail architecture: one tail is derived from heptadecan-9-ol (a branched C17 secondary alcohol), while the other tail is a modified nonyl chain (C9) with a key ethyl branch at the 3-position. The linker connecting the head group to the tails has a length equivalent to n=3 (three methylene units) as defined in the study. This specific combination of the secondary amine cyclic ether head group, asymmetric tails, and the ethyl branch at the 3-position of the nonyl chain proved critical for its exceptional performance. When formulated into LNPs and administered intravenously in mice, Lipid 17 demonstrated a remarkable 6-fold increase in functional protein (eGFP) expression in the liver compared to the benchmark lipid MC3, with high statistical significance (P < 0.0001). This makes Lipid 17 one of the most active lipids identified in the study and a promising candidate for liver-targeted mRNA therapeutics.​​

OF-02 (OF-2) is an alkenyl amino alcohol (AAA) ionizable lipid for highly potent in vivo mRNA delivery.Alkenyl amino alcohols (AAA) are a functional group found in sphingosine and other bioactive molecules. It was used to prepare AAA-based ionizable lipids through ring-opening reactions between alkenyl epoxides (AEs) and polyamine cores. These AAA-based iLNPs could promote high-level protein expression Therefore, AAA-based ionizable lipids OF-00, OF-01, OF-02, and OF-03 were prepared. The results of in vivo delivery of human erythropoietin (hEPO) mRNA showed that the AAA ionizable lipid OF-02 with the linoleic acid derivative could effectively deliver hEPO mRNA. Compared with the positive control CKK-E12, OF-02 showed an increased ability to induce serum EPO protein expression by nearly twofold (Figure 7b). Likewise, it outperformed two benchmark ionizable lipids (503013 and C12-200) in the nucleic acid delivery field. Furthermore, the mRNA delivered by OF-02 iLNPs was mainly in vivo.translated into the liver. The liver-targeting ability of OF-02 iLNPs improves their delivery efficiency. Therefore, the OF-02 iLNPs may become excellent delivery vehicles for the treatment of liver diseases without other side effects of damage to other organs during the treatment
