  Selective Disruption of Early/Recycling Endosomes: Release of Disulfide-Linked Cargo Mediated by a N-Alkyl-3β-Cholesterylamine-Capped Peptide

  摘要：

  The use of endocytic uptake pathways to deliver poorly permeable molecules into mammalian cells is often plagued by entrapment and degradation of material in late endosomes and lysosomes. As a strategy to prevent the exposure of cargo to these highly hydrolytic membrane-sealed compartments, we synthesized derivatives of the membrane anchor N-alkyl-3 beta-cholesterylamine that selectively target linked compounds to less hydrolytic early/recycling endosomes. By targeting a pH-dependent membrane-lytic dodecapeptide and dislufide-linked flurophore to these compartments in Chinese hamster ovary cells or Jurkat lymphocytes, membranes of early-recycling endosomes were selectively disrupted, resulting in cleavage of the disulphide and escape of the fluorophore into cytosol and nucleus with low toxicity. The ability os appropriately designed N-alkyl-3 beta-cholesterylamines to deliver cargo into and release dislufide-linked cargo from relatively nonhydrolytic early/recycling endosomes may be useful for the delivery of a variety of sensitive molecules into living mammalian cells.

  The present invention relates to new synthetic receptors. More particularly, the present invention relates to methods for synthesizing preferred membrane-binding elements, preferably cholesterylamine derivatives, including 3β-amino-5-cholestene (3β-cholesterylamine) and related 3β-halides through i-steroid and retro-i-steroid rearrangements. The invention further relates to use of the synthetic receptors for delivering a protein, peptide, drug, prodrug, lipid, nucleic acid, carbohydrate or small molecule into a target cell via receptor-mediated endocytosis. According to the invention, novel synthetic mimics of cell surface receptors have been designed and methods for use of the same are disclosed.

  本发明涉及新的合成受体。更具体地说，本发明涉及用于合成首选膜结合元素（优选为胆固醇胺衍生物，包括3β-氨基-5-胆甾烷（3β-胆固醇胺）和相关的3β-卤化物）的方法，包括通过i-类固醇和retro-i-类固醇重排。本发明进一步涉及利用合成受体通过受体介导的内吞作用将蛋白质、肽、药物、前药、脂质、核酸、碳水化合物或小分子输送到靶细胞的用途。根据本发明，新的细胞表面受体合成类似物已被设计，并公开了使用这些类似物的方法。
