DSPE-PEG-N3 is a click chemical PEG reagent. Azide group is easy to react with alkynyl group under the catalysis of copper catalyst. It can also react directly with DBCO without any catalyst. DSPE (1,2-distearoyl-sn-glycerol-3-phosphoethanolamine) is a saturated 18 carbon phospholipid, which is commonly used in the synthesis of liposomes. Polyethylene glycol (PEG) - coupled DSPE is hydrophilic and can be used for drug delivery, gene transfection and biomolecular modification. The PEG of phospholipid significantly improved the blood circulation time and stability of the capsule drug. Polyethylene glycol can enhance the solubility and stability, reduce the non-specific binding of charged molecules on the surface, and reduce the immunogenicity of polypeptides. Azide (- N3) can react with copper catalyzed alkynes in aqueous solution and be reduced to amino groups. Polyethylene glycol can increase solubility and stability. It can also inhibit the nonspecific binding of charged molecules on the modified surface.

L202 is an ionizable lipid designed for mRNA vaccines, featuring a pH-responsive N-methylpiperidine head and a unique branched-tail structure with ester linkages to enable biodegradability. With a pKa of ~6.04–6.29, it facilitates efficient endosomal escape while maintaining stability in physiological conditions. Formulated into lipid nanoparticles (LNPs) of ~103 nm (PDI 0.08), L202 achieves >97% mRNA encapsulation efficiency. Its optimized structure drives robust immunogenicity: in mice, a single 0.1–10 μg dose induced dose-dependent SARS-CoV-2 spike-specific IgG titers, outperforming MC3-based LNPs and protein-alum vaccines. L202-LNPs elicited balanced Th1/Th2 responses (IgG2a/IgG1 ratio) and potent germinal center B cell activation, critical for durable immunity. Lyophilization with 16% sucrose preserved mRNA integrity and immunogenicity after 1-month storage at 5°C or 25°C, addressing cold-chain limitations. In nonhuman primates, two 100-μg doses generated neutralizing antibody titers exceeding convalescent human sera, with broad efficacy against Alpha, Beta, Gamma, and Delta variants. Rapid tissue clearance (72 hours post-injection) and minimal hepatic accumulation, attributed to ester hydrolysis, enhanced safety profiles. Additionally, L202-LNPs functioned as intrinsic adjuvants, amplifying protein vaccine responses. Combined with its lyophilization compatibility, potent cross-variant immunity, and favorable pharmacokinetics, L202 represents a promising platform for next-generation mRNA vaccines.
