DOPE-PEG2000-EB1

(Synonyms: DOPE-PEG2000-Mal-Cys-LIRLWSHLIHIWFQNRRLKWKKK)

DOPE-PEG2000-EB1 (DOPE-PEG2000-Mal-Cys-LIRLWSHLIHIWFQNRRLKWKKK) is an amphiphilic lipid-PEG-peptide conjugate composed of DOPE (1,2-dioleoyl-sn-glycero-3-phosphoethanolamine), PEG2000, and the EB1 peptide (a penetratin analog). EB1 peptide is an endosomolytic agent that forms an amphipathic alpha helix upon protonation in endosomes, driving endosomal membrane permeabilization. DOPE-PEG2000-EB1 is used for intracellular delivery of nucleic acids (e.g., siRNA) and other macromolecular therapeutics.

Biological Activity

Description

In Vitro

DOPE-PEG2000-EB1: functionalization of liposomes and nanoparticles for enhanced intracellular delivery of siRNA, nucleic acids, and macromolecular drugs, particularly to overcome the endosomal escape barrier.
Structural composition:
(1) DOPE; a fusogenic phospholipid with two oleoyl chains that anchors into lipid bilayers and promotes membrane destabilization and fusion under acidic conditions;
(2) PEG2000; a hydrophilic polymer that provides steric stabilization, reduces opsonization, and extends circulation time;
(3) EB1 peptide; a penetratin analog and endosomolytic agent that forms an amphipathic alpha helix upon protonation in early-to-late endosomes, permeabilizing endosomal membranes and enabling encapsulated cargo (e.g., siRNA) to escape into the cytosol for effective gene silencing.
