The present invention relates to an amphiphilic compound having a dendronic hydrophobic group, a method for preparing the same, and a method for extraction, solubilization, stabilization, or crystallization of a membrane protein by using the same. The use of the compound according to the present invention leads to an excellent membrane protein solubilization effect and a stable storage of a membrane protein in an aqueous solution for a long time, and thus can be utilized for functional analysis and structural analysis of the membrane protein. Especially, the amphiphilic compound having a dendronic hydrophobic group showed very remarkable characteristics in the visualization of protein composites through an electronic microscope. The membrane protein structural and functional analysis is one of the fields of greatest interest in current biology and chemistry, and more than half of the new drugs that are currently being developed are targeted at membrane proteins, and thus the amphiphilic compound of the present invention can be applied to membrane protein structure studies closely related to the development of new drugs.
The present invention provides a technique capable of transferring an active ingredient, particularly, a nucleic acid, to a cell with excellent efficiency and a cationic lipid for use in this technique, etc. The cationic lipid of the present invention is a compound represented by the formula (I) or a salt thereof. n1 represents an integer of 2 to 6, n2 represents an integer of 0 to 2, n3 represents an integer of 0 to 2, L represents —C(O)O— or —NHC(O)O—, Ra represents a linear C

Disclosed herein are polyethylene glycol (PEG)-lipids, functionalized PEG-lipids, and functionalized PEG-lipids that are conjugated to a binding moiety which can comprise an antibody antigen binding domain. Also disclosed are methods for synthesizing and functionalizing the PEG-lipids. The PEG-lipids are useful components lipid nanoparticles (LNP) used for the delivery of nucleic acids into living cells, in vivo or ex vivo. LNP comprising functionalized PEG-lipids that are conjugated to a binding moiety are useful as targeted LNP for delivering nucleic acids into cells or tissues expressing the ligand of the binding moiety.
