摘要:
The invention pertains to a lipid-based microbubble stably binding a plurality of nucleic acids, and a method of delivering the microbubble and nucleic acids to a specific target site using ultrasound. The delivered nucleic acids create transgenic cells (i.e., for example, a transgenic tumor cell), wherein the transgenic cell expresses the proteins encoded by the delivered nucleic acids. This technology provides a significant improvement for microbubble-drug delivery platforms as known microbubble do not efficiently bind nucleic acids. The improvements described herein include but are not limited to identifying proper lipid proportionality ratios and/or cationic surfactant layers that provide an optimum mechanical index compatible with ultrasonics. Microbubble perfusion and/or nucleic acid delivery may be performed by a combination of imaging and ultrasound/microbubble targeted delivery to simultaneously perform low power two-dimensional imaging and high power microbubble destruction. Such systems are useful in therapeutics and/or diagnositics. For example, the data disclosed herein shows proof of principle in conjunction with the deliviery of therapeutic siRNA molecules to slow tumor growth.
摘要:
The present invention relates to reverse micelle system based on sterols, acylglycerols, phospholipids or sphingolipids and nucleic acids. The reverse micelle system of the invention is able to cross mucosa and cellular membranes. It thus allows vectorization of nucleic acids to target sites. It is advantageously useful in the pharmaceutical and dietetic fields.

摘要:
MuIti-component therapeutic strategies are frequently indicated for the treatment of heterogeneous diseases as cancer. However, the antitumor activity of drug combinations is extremely dependent of the molecular ratio of the combined drugs. This patent describes a multi -targeting system comprising a nanocarrier that was engineered in order to exhibit small size, high stability over time, high encapsulation yields of nucleic acids and the ability to specifically bind to receptors overexpressed at the surface of cancer cells. Further developments were performed in order to simultaneously encapsulate nucleic acids (gene silencing agents) and antitumural drugs (imatinib) in molar ratios allowing both molecules to be used in therapeutic doses. Therefore, with this product it is possible to mediate specific delivery to cancer cells and to address two specific molecular targets (a transcript and a protein) This unique properties thus render the system a great potential for cancer treatment, namely when resistance to chemotherapy is associated.

Es wird ein Konjugat aus Agens-Komplex und mindestens einem Zielfindungsliganden, wobei der Agens-Komplex ein Agens umhüllt von einem Hüllmaterial umfasst und wobei der Zielfindungsligand ein Prostacyclinanalogon ist, sowie dessen Verwendung beschrieben.
摘要:
A lipid particle can include a plurality of cationic lipids, such as a first cationic lipid and a second cationic lipid. The first cationic lipid can be selected on the basis of a first property and the second cationic can be selected on the basis of a second property. The first and second properties are complementary. The attributes of the lipid particle can reflect the selected properties of the cationic lipids, and the complementary nature of those properties.
