摘要:
The present invention provides compositions and methods for the delivery of therapeutic agents to cells. In particular, these include novel lipids and nucleic acid-lipid particles that provide efficient encapsulation of nucleic acids and efficient delivery of the encapsulated nucleic aicd to cells in vivo . The compositions of the present invention are highly potent, thereby allowing effective knock-down of 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. Formulae (I), (II), (III), (IV).
