The present invention provides a cationic lipid which is able to be used for nucleic acid delivery to the cytoplasm. A cationic lipid according to the present invention is, for example, a compound represented by formula (1) or a pharmaceutically acceptable salt thereof, wherein L
1
and L
2
independently represent an alkylene group having 3 to 10 carbon atoms; R
1
and R
2
independently represent an alkyl group having 4 to 24 carbon atoms or an alkenyl group having 4 to 24 carbon atoms; R
3
represents an alkyl group having 1 to 3 carbon atoms; and X
1
represents a single bond or CO—O—.

The present invention provides a cationic lipid which is able to be used for nucleic acid delivery to the cytoplasm. A cationic lipid according to the present invention is, for example, a compound represented by formula (1a) or a pharmaceutically acceptable salt thereof. (In formula (1a), each of L1 and L2 independently represent an alkylene group having 3-10 carbon atoms; each of R1 and R2 independently represent an alkyl group having 4-22 carbon atoms or an alkenyl group having 4-22 carbon atoms; X1 represents a single bond or -CO-O-; and ring P represents one of formulae (P-1) to (P-5).)(In formulae (P-1) to (P-5), R3 represents an alkyl group having 1-3 carbon atoms.)

The disclosure features novel lipids and compositions involving the same. Lipid nanoparticles (e.g., empty LNPs or loaded LNPs) include a novel lipid as well as additional lipids such as phospholipids, structural lipids, and PEG lipids. Lipid nanoparticles (e.g., empty LNPs or loaded LNPs) further including therapeutic and/or prophylactics such as RNA are useful in the delivery of therapeutic and/or prophylactics to mammalian cells or organs to, for example, regulate polypeptide, protein, or gene expression.
