CureVac Lipid C24(CVL1,VitE-C4DE-Pip- S) Datasheet DC Chemicals
Description
CVL1 (C24) is an ionizable lipid developed by CureVac for mRNA delivery, featuring a vitamin E (α-tocopherol) core linked via a thioether bridge to piperidine-based cationic headgroups. Its unique design enables pH-dependent charge switching (neutral at physiological pH, cationic in endosomes) for efficient mRNA encapsulation and endosomal escape. Formulated in lipid nanoparticles (LNPs) with DPhyPS and PMOZ4, CVL1 preferentially targets spleen and lymph node dendritic cells (DCs), enhancing antigen presentation and T-cell immunity. Key advantages include high mRNA encapsulation (>90%), stability under lyophilization, and reduced liver accumulation compared to PEGylated LNPs. In preclinical studies, CVL1-based LNPs induced robust CD8+/CD4+ T-cell responses and IgG2a-dominant antibody titers against tumor antigens (e.g., Trp2). With a particle size of 70–120 nm and low polydispersity (PDI <0.2), CVL1 balances delivery efficiency and biocompatibility, making it ideal for cancer and infectious disease vaccines requiring strong cellular immunity. Its degradable ester and thioether bonds further improve safety profiles.
