一种含有多级叔胺的不对称阳离子脂质

Resumen de: WO2025140594A1

The present invention belongs to the field of drug delivery. Provided is an asymmetric cationic lipid containing multiple tertiary amines, of which the structure is shown as a general formula (1), wherein the definition of each symbol is consistent with that in the description. In the present invention, a degradable group is introduced into a proper position of the cationic lipid, and the presence of the degradable group enables an LNP-drug composition prepared from the cationic lipid to be degradable in endosomes at a proper time and to have small cytotoxicity, thereby solving the problem that in the prior art, LNP-drug compositions prepared from non-degradable lipids will accumulate in endosomes and acidify the endosomal environment, which hinders the endosomal escape of drugs (such as mRNAs) and causes that the drugs delivered into cells fail to sufficiently exert the therapeutic effects. The cationic lipid in the present invention uses a heterofunctionalized piperazine-containing small molecule as a raw material, involves a simple preparation process and a lower cost, and is more green and environmentally-friendly. An LNP-mRNA composition prepared from the cationic lipid has the advantages of low toxicity, high biocompatibility, high cell transfection, etc.
