Abstract: Despite the widespread use of nanotechnology in radio-imaging applications, lipoprotein based delivery systems received only limited attention so far. The subject application provides for the synthesis of a novel hydrophobic radio-imaging tracer. This tracer, comprising a hydrazinonicotinic acid (HYNIC)-N-dodecylamide and 99mTc conjugate can be encapsulated into rHDL nanoparticles (NPs). These rHDL NPs can selectively target the Scavenger Receptor type B1 (SR-B1) that is overexpressed on most cancer cells due to excess demand for cholesterol for membrane biogenesis and thus can target tumors in-vivo. Details of the tracer synthesis, characterization of rHDL/tracer complex, in-vitro uptake, stability studies and in-vivo application of this new radio-imaging approach are provided.

Abstract: The present invention provides high density lipoprotein (HDL) or reconstituted HDL (rHDL) particles for the delivery of non-nucleic acid therapeutic agents, therapeutic agents or nucleic acids to cells and tissues. The use of HDL or rHDL particles has advantages over other delivery systems because they are smaller in size and their contents are rapidly internalized by receptors of specific cells, including receptors on the surface of tumor tissue. The HDL or rHDL nanoparticles of the present invention may include a positively charged polyamino acid, which neutralizes the negatively charged nucleic acid, thus allowing for successful incorporation of the nucleic acid into an HDL or rHDL particle. Methods of delivering therapeutic agents to cells and target tissues using the disclosed HDL or rHDL particles are provided as are methods of treating various diseases and disorders.

Abstract: Compositions and methods for delivery of a pharmaceutical to an individual. Delivery vehicles are provided in a formulation of a pharmaceutical that is encapsulated in a synthetic self assembled nanoparticle that includes a lipid binding protein and a lipid monolayer. The interior of the particle represents a hydrophobic core region where lipophilic highly-water insoluble drug molecules may be incorporated. In contrast to liposomes, that include an aqueous interior core surrounded by phospholipid bilayer, the drug carrier nanoparticle described here is composed of a monolayer and a hydrophobic interior.
