Publication number: 20120202871Abstract: The present invention provides compositions and methods for the delivery of therapeutic agents to cells. In particular, these include novel cationic lipids and nucleic acid-lipid particles that provide efficient encapsulation of nucleic acids and efficient delivery of the encapsulated nucleic acid to cells in vivo. The compositions of the present invention are highly potent, thereby allowing effective knock-down of a specific target protein at relatively low doses. In addition, the compositions and methods of the present invention are less toxic and provide a greater therapeutic index compared to compositions and methods previously known in the art.Type: ApplicationFiled: June 30, 2010Publication date: August 9, 2012Inventors: James Heyes, Lorne Palmer, Magdalena Maslowski, Ian MacLachlan

Patent number: 8158827Abstract: Disclosed are cationic lipid compounds and compositions of lipid aggregates for delivery of macromolecules and other compounds into cells. The compounds can be used alone or in combination with other compounds to prepare liposomes and other lipid aggregates suitable for transfection or delivery of compounds to target cells, either in vitro or in vivo. The compounds are preferably polycationic and preferably form highly stable complexes with various anionic macromolecules, particularly polyanions such as nucleic acids. These compounds have the property, when dispersed in water, of forming lipid aggregates which associate strongly, via their cationic portion, with polyanions. Also disclosed are intermediates for preparing the compound and compositions of the invention and methods of using the compounds to introduce other compounds into cells.Type: GrantFiled: January 14, 2009Date of Patent: April 17, 2012Assignee: Life Technologies CorporationInventors: Yongliang Chu, Malek Masoud, Gulilat Gebeyehu
