Popis: Amino acid-tuned self-assembly has become an attractive strategy for constructing various functional materials. Here, a series of dibenzocyclooctyne (DIBO) functionalized amphiphilic amino acid derivatives are designed and screened as building blocks of functional supramolecular self-assembly nanoparticles for cancer immunotherapy. One top-performing supramolecular self-assembly material (named DA6C1) is identified through combinatorial screening, and spherical nanoparticles can be easily prepared by this material tuned multicomponent synergistic self-assembly of ovalbumin (OVA) and CpG oligonucleotide. DA6C1 based nanovaccine can significantly enhance the cellular uptake of OVA and CpG into the same bone marrow derived dendritic cells (BMDCs) and greatly improve the activation of DCs. Moreover, after subcutaneous injection, this nanovaccine flows rapidly to the lymph nodes and elicits strong immune responses to achieve effective prophylactic and therapeutic effect. Therefore, our work highlights the great potential of clickable amino acid derivatives as a convenient and powerful tool to construct nanovaccine for effective immunotherapy.
