The invention relates to an oil-in-water nanoemulsion for MRI, including:
an aqueous phase,
a fluorinated phase including at least one fluorinated oil,
a surfactant at the interface between the aqueous and fluorinated phases, the surfactant comprising:
at least one amphiphilic targeting ligand,
at least one amphiphilic lipid, and
at least one diblock or triblock fluorophilic compound,
as well as to the use thereof as a contrast agent.
Electrochemical fluorination of N-cyclopentylpyrrolidine gave the corresponding F-amine together with a ring-opened compound N-(F-pentyI)-F-pyrrolidine in the ratio of 1 to 1, in 55% yield. N-cyclohexylpyrrolidine, N-cyclopentylpiperidine, and N-cyclohexylpiperidine were also eletrochemically fluorinated in the same manner to give the corresponding F-amines, their isomers with rearranged structures

Perfluorocarbon emulsions may be used to enhance the activity of lipophilic drugs, chemotherapy and chemical and radiation therapy of cancer. Preferred methods for preparing the emulsion and compositions comprising the emulsion are described.
Compositions having enhanced gas and drug transporting capability, are prepared by providing a perfluoro compound dispersed in an aqueous medium with a surfactant to form an aqueous initial dispersion, concentrating the perfluoro compound phase of the dispersion as by centrifugation or filtration, wherein a portion of the surfactant remains complexed with the particles of the perfluoro compound phase and the balance of the surfactant is in the aqueous phase, separating the phases, and redispersing the particles of the concentrated perfluoro compound phase to form a final dispersion in which a major portion of the surfactant is complexed with the perfluoro compound particles.

The present invention is directed, inter alia, to compositions and their use for delivering compounds into a cell. In a preferred embodiment, the compositions comprise, in combination with the compound to be delivered, an organic halide, a targeting ligand, and a nuclear localization sequence, optionally in the presence of a carrier. Ultrasound may be applied, if desired. The compositions are particularly suitable for the treatment of inflammatory diseases.
