E10i-494 is a branched ionizable lipid designed to enhance the delivery of mRNA and CRISPR-Cas9 ribonucleoprotein (RNP) complexes. It belongs to the Branched Endosomal Disruptor (BEND) lipid family, which features terminal branching to improve endosomal escape and cellular uptake.E10i-494 demonstrated exceptional performance in T cell engineering, achieving >80% transfection efficiency in primary human T cells.

IAJD-34 is a one-component ionizable amphiphilic Janus dendrimer specifically engineered for targeted mRNA delivery to the lung parenchyma, as described by Meshanni et al. in Nature Communications article "Targeted delivery of TGF-β mRNA to murine lung parenchyma using one-component ionizable amphiphilic Janus Dendrimers" . This synthetic nanoparticle self-assembles with mRNA through simple mixing in acetate buffer, forming stable dendrimersomes approximately 93-97 nm in size with high encapsulation efficiency (>95%) and a positive zeta potential (~48 mV). Its defining feature, highlighted in the study, is exceptional lung tropism after intravenous injection, enabling significantly higher luciferase expression in murine lungs compared to other organs. As demonstrated by Meshanni et al., IAJD 34 effectively delivers therapeutic mRNA (e.g., TGF-β mRNA) to the lower lung, inducing transient protein production with minimal systemic toxicity at appropriate doses (e.g., 10 µg), offering a promising strategy for treating parenchymal lung diseases.

​​C-a16​​ is an ionizable lipid engineered through Mannich reaction chemistry, designed to revolutionize mRNA delivery by synergizing high efficiency with minimized immune activation. Synthesized by reacting a phenolic tail derivative, formaldehyde, and a branched tertiary amine core under optimized ethanol conditions, this lipid integrates antioxidant phenol groups directly into its structure. These phenol moieties serve as intrinsic radical scavengers, effectively neutralizing intracellular reactive oxygen species that typically degrade mRNA and trigger inflammation.In lipid nanoparticle formulations, C-a16 constitutes the functional backbone, enabling superior mRNA encapsulation efficiency while maintaining a stable nanoparticle size of approximately 80–100 nm. Critically, it outperforms conventional lipids like DLin-MC3-DMA by achieving significantly higher target-protein expression in vivo alongside markedly reduced pro-inflammatory cytokine secretion. The antioxidant capability is not incidental but fundamental—quenching the phenol groups drastically diminishes both ROS suppression and delivery efficacy, confirming the design's mechanistic elegance.C-a16 represents a paradigm shift: its biomimetic antioxidant architecture addresses the chronic trade-off between delivery potency and immunogenicity, unlocking safer therapeutic applications for vaccines and gene therapies.

306-N16B is a lipidnanoparticle, and allows systemic codelivery of Cas9 mRNA and sgRNA. 306-N16B can transport mRNA to the pulmonaryendothelial cell. 306-N16B can be used for research of genome editing-based therapies. Based on the same lipid libraries with 306-O12B, the researchers also found that N-series ionizable lipids were able to selectively deliver mRNA to the lungs of mice. Compared with the liver-targeted O-series ionizable lipids which contained ester bond in lipid tail found in previous work, such as 306-O12B, the N-series ionizable lipids with the lipid tail containing amide bond prefer to deliver mRNA to the lung. As a N-series ionizable lipid, the chemical structure of the 306-N16B is shown in Figure 4a,b. The difference of organ targeting may be due to their adsorption of different protein coronas during blood circulation caused by their different structures mentioned earlier.It has shown that the second major protein of the protein corona adsorbed by liver-targeting 306-O12B iLNPs was apolipoprotein E (ApoE), while the three dominant proteins in the protein corona adsorbed by lung-targeting 306-N16B iLNPs were serum albumin, fibrinogen beta chain, and fibrinogen gamma chain. However, the 306-N16B iLNPs showed less organ selectivity when systematically codelivered Cas9 mRNA and sgRNA in vivo, which could simultaneously activate tdTomato expression in the liver and lung of Ai14 mice, whereas single mRNA delivery could almost exclusively deliver mRNA to the lungs. This surprising phenomenon requires further investigation. Both the change of iLNPs charge and the change of lipids functional group can influence the distribution of iLNPs in vivo due to the altering of protein corona composition. Therefore, it is possible to control the organ targeting of iLNPs by controlling the composition of the outer protein corona of iLNPs.

L649 is a next-generation, lung-targeting ionizable lipid specifically designed for systemic mRNA delivery developed by Hopewell. Belonging to the novel "N-series" lipid class, it features a unique structure with an amine-containing head group and hydrophobic tails incorporating amide bonds. This design enables L649 to form highly stable lipid nanoparticles (LNPs) that exhibit exceptional tropism for the lower respiratory tract (lungs, bronchi, trachea) following intravenous administration. It demonstrates superior efficiency in delivering therapeutic payloads (like mRNA) specifically to key lung cell types, including alveolar epithelial cells (AT1 and AT2) and bronchial cells, while minimizing off-target accumulation in organs like the liver. L649-based LNPs, particularly when formulated with helper lipids like POPE, combine high potency with significantly improved tolerability, allowing for effective dosing in vivo. This makes L649 a promising candidate for developing treatments for various lung diseases such as pulmonary fibrosis, COPD, lung cancer, and infectious diseases like COVID-19.​

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.​​

Compared to GL3 (TRIS scaffold, same PEG length), GL6’s simplified lysine scaffold improves manufacturability. In LDLR-deficient models, GL6 enabled ​61% liver editing (vs. 5% with standard LNPs) at 2 mg/kg, demonstrating superior ASGPR targeting. Its design minimizes ligand crowding (0.05 mol% surface density) while maximizing endosomal escape and durable gene editing.
