Supramolecular nanogels cross-linked by host-guest interaction between dextran grafted benzimidazole (Dex-g-BM) and thiol-β-cyclodextrin were designed. Their special supramolecular pH-sensitivity under acidic conditions (pH < 6, within the range of malignant cellular endosomes) and reduction sensitivity in response to biologically relevant stimuli will be of great advantage to the future of cancer chemotherapeutics.
设计了通过葡聚糖接枝苯并咪唑(Dex-g-BM)与硫醇-β-环糊精之间的主客体相互作用交联的超分子纳米凝胶。它们在酸性条件下(pH < 6,在恶性细胞内体范围内)具有特殊的超分子pH敏感性,并且对生物相关刺激具有还原敏感性,这将对未来的癌症化疗具有很大优势。
