The present application provides a branched cationic lipid containing an ester bond, the structure of which is represented by formula (1), wherein the definition of each symbol is consistent with that described herein. The branched cationic lipid containing an ester bond has a plurality of hydrophobic hydrocarbon tail chains. The cross-sectional area of the hydrophobic end increases, forming a conical geometric configuration, which is conducive to promoting membrane fusion and content release; moreover, a charged head group can interact with oppositely charged molecules on the cell membrane, thereby enabling the multi-tailed lipid to pass through the cell membrane more easily and exert its endosome-disrupting effect inside the cell, and thus improving drug release efficiency. The branched cationic lipid containing an ester bond of the present application comprises one or more biodegradable groups between a branching center and the hydrophobic tails. The presence of the degradable groups enables a lipid nanoparticle (LNP) prepared from the branched cationic lipid to be degraded timely within endosomes, such that the endosomal escape of drug molecules (such as nucleic acids) is promoted, thereby solving the problem that drugs delivered into the cell fail to exert their effects.
