(214) Novel Ether-Ionizable Lipids Complexed into Lipid Nanoparticles Enhance mRNA Delivery Efficiency

Introduction:

The ionizable lipid within lipid nanoparticles (LNPs) is pH-responsive, enabling cytosolic nucleic acid delivery [1,2]. Ionizable lipid design drives nucleic acid delivery efficiency [3], but structure:function relationships between lipid design and LNP delivery are not well understood. We synthesized a series of novel ionizable lipids with different numbers of ether groups and alkyl-tail lengths and identified top-performing ionizable lipids for mRNA delivery to cells. This work aims to understand how ether groups and tail length influence delivery while providing new lipids for diseases.

Learning Objectives:

Understand relationships between number of ethers and tail lengths and mRNA delivery.
Assess how ionizable lipid structure influences endocytic pathways.
Recognize that ether groups can greatly alter biodistribution in mice.
