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

AA-T3A-C12 is a leading anisamide-tethered lipidoid (AA-lipidoid) identified through a combinatorial library screening for targeted RNA delivery to activated fibroblasts, offering a promising approach to treat liver fibrosis.AA-T3A-C12 is a leading anisamide-tethered lipidoid (AA-lipidoid) identified through a combinatorial library screening for targeted RNA delivery to activated fibroblasts, offering a promising approach to treat liver fibrosis. It is synthesized via a one-pot, two-step modular method that combines anisamide—a ligand for sigma receptors overexpressed on activated hepatic stellate cells (HSCs)—with a T3A polyamine core and C12 epoxide tails, enabling efficient siRNA encapsulation in lipid nanoparticles (LNPs). In vitro, AA-T3A-C12 LNPs exhibit enhanced cellular uptake and gene silencing in activated fibroblasts, dependent on sigma receptor binding, as confirmed by haloperidol blockade studies, and outperform non-targeted analogs and the FDA-approved MC3 LNPs in fibroblast selectivity.In a mouse model of CCl4-induced liver fibrosis, AA-T3A-C12/siHSP47 LNP achieves approximately 65% knockdown of heat shock protein 47 (HSP47), a key fibrotic target, leading to significant reduction in collagen deposition and fibrosis alleviation, with a good safety profile and no exacerbation of liver injury.

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.

Lipid 5 is an ionizable lipid based on a macrocyclic cyclam headgroup. Its structure incorporates a benzylmethyl carbonate (BMC) linker, which contains an aromatic benzene ring, and a saturated C18 hydrophobic tail. Lipid 5 was mixed with helper lipids at a fixed molar ratio and formulated into mRNA-loaded lipid nanoparticles (LNPs) using microfluidic technology. Characterization data show that these LNPs have a hydrodynamic diameter of approximately 50-80 nanometers and a polydispersity index (PDI) below 0.2, indicating a small particle size with a uniform distribution. Their zeta potential at physiological pH is near neutral (ranging from -3 to +3 mV). The mRNA encapsulation efficiency, as determined by the Ribogreen assay, exceeds 95%. Cryo-transmission electron microscopy images reveal that the LNPs exhibit a typical spherical bilayer structure. In in vitro experiments, Lipid 5 LNPs mediated a higher level of luciferase protein expression in HEK293FT cells compared to the benchmark lipid DLin-MC3-DMA. In Balb/c mice, intravenous injection of LNPs encapsulating luciferase mRNA resulted in in vivo imaging signals predominantly concentrated in the lungs. Quantitative analysis indicated that the signal intensity in the lungs was over 100 times greater than that in the liver, with more than 95% of the total signal distributed in the lungs. In Ai9 reporter gene mice, two intravenous injections of Lipid 5 LNPs encapsulating Cre mRNA led to quantitative analysis of lung tissue sections showing that approximately 30% of lung cells were positive for tdTomato signal.
