This disclosure provides compositions consisting of solid mixture of cationic lipids and a polynucleotide, wherein the cationic lipid molecules form a water-insoluble ionic complex with the polynucleotide. What is also described is an anhydrous mixture of the cationic lipids and the polynucleotide solubilized in an organic or polar aprotic solvent. The anhydrous compositions are useful in preparing therapeutic formulations and in the diagnosis and treatment of diseases and conditions. The compositions are useful for delivery of agents such as nucleic acid therapeutics to cells, tissues, organs, and subjects.

What is described are macrocyclic compounds formed by reaction of a cyclic compound, which contains an amine, with an epoxide. The macrocyclic compound has the following structure: When substituents R and R′ that are hydrophobic substituents, the macrocyclic compound functions as a lipid and is compatible with lipid systems, including liposomes and lipid particles. When present in certain lipid systems, the macrocyclic compound enhances the ability of the lipid system to facilitate delivery of therapeutic molecules to target cells in a mammalian subject.

摘要:
Compositions and methods are provided that include a biologically active agent and a permeabilizing agent effective to enhance mucosal delivery of the biologically active agent in a mammalian subject, in which the permeabilizing peptide is a tight junction modulating peptide (TJMP), a TJMP analogue, a conjugate of a TJMP, a conjugate of a TJMP analogue, or complexes thereof. The permeabilizing agent reversibly enhances mucosal epithelial paracellular transport, typically by modulating epithelial junctional structure and/or physiology at a mucosal epithelial surface in the subject.

摘要:
Nanoparticles of double-stranded nucleic acid complexed about a complexing agent such as the melamine derivatives of formulae I and II, preferably forming a trimeric nucleic acid complex. In alternative embodiments, polyarginine or a polymer of Gln and Asn further complexed with the double-stranded nucleic acid complex. In a preferred embodiment, the ds nucleic acid is a double stranded RNA having 15 to 30 base pairs suitable for RNA interference. In another aspect of the invention, a ds RNA is produced in which all of the uridines are changed to 5-methyluridine. Preferably, the resultant ds RNAs have 15 to about 30 base pairs and are suitable for RNA interference.
