Patent number: 9725720Abstract: 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 demonstrates enhanced efficacy along with lower liver toxicity as a result of lower lipid levels in the liver. The present invention employs low molecular weight cationic lipids with one short lipid chain to enhance the efficiency and tolerability of in vivo delivery of siRNA.Type: GrantFiled: September 30, 2016Date of Patent: August 8, 2017Assignee: SIRNA THERAPEUTICS, INC.Inventors: John A. Bawiec, III, Zhengwu J. Deng
