AMPHIPATHIC MOLECULE, MOLECULAR AGGREGATE COMPRISING THE AMPHIPATHIC MOLECULE, AND USE OF THE MOLECULAR AGGREGATE

摘要

Disclosed is an amphipathic molecule having two or more zwitterionic functional groups in its hydrophilic moiety. Also disclosed is a molecular aggregate comprising the amphipathic molecule as a constituent lipid. The molecular aggregate can form a stable vesicular structure under a physiological pH environment to carry a substance of interest in the vesicular structure, and can release the substance of interest to the outside of the vesicular structure when the vesicular structure is deformed under an acidic pH environment. The molecular aggregate can be used as a transporter for a drug, a probe, a nucleic acid, a protein or the like.
