  • Patent number: 9670487
    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 susceptible to hydrolytic instability that may translate into reduced liver residence times and reduced hepatocellular toxicity. The present invention employs acetals and ketals to provide a low pH sensitive chemical handle for degradation.

  • Publication number: 20170135962
    Abstract: The instant invention provides for novel cationic lipids of Formula A 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 coupled with inclusion of hydrolysable functionality in the lipid chains to enhance the efficiency and tolerability of in vivo delivery of siRNA.
