Abstract
The instant invention provides for novel cationic lipids that can be used in combination with other lipid components such as cholesterol and PEG-lipids to form lipid nanoparticles with oligonucleotides. It is an object of the instant invention to provide a cationic lipid scaffold that is more efficacious than traditional cationic lipids. The present invention employs amino alcohols to enhance the efficiency of in vivo delivery of siRNA.
