peptides and other medicinal molecules across tight epithelial barriers would overcome the major obstacle to oral delivery. We have already demonstrated that peptides conjugated to gangliosides (GM1 and GM3) having non-native short N-acyl groups hijack the endogenous process of intracellular lipid sorting resulting in transcytosis and delivery across epithelial barriers in vitro and in vivo. Here, we report
治疗性肽和其他药物分子穿过紧密的上皮屏障的稳健运输将克服口服递送的主要障碍。我们已经证明,与具有非天然短 N-酰基的神经节苷脂(GM1 和 GM3)结合的肽会劫持细胞内脂质分选的内源性过程,从而在体外和体内导致转胞吞作用和跨上皮屏障的递送。在这里,我们报告了将肽直接共价结合到短酰基链 C6-神经酰胺的合成方法。我们发现短酰基链神经酰胺结构域仅负责体外转胞吞作用。这澄清并扩展了短酰基链鞘脂的平台,用于将共轭肽从神经节苷脂传递到神经酰胺本身,穿过紧密的粘膜细胞屏障。
