RECONSTITUTED HDL NANOPARTICLES FOR DELIVERY OF RADIOACTIVE AGENTS AND USES THEREOF
20220008571 · 2022-01-13 ·

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 .sup.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.
