专利号:US-12208146-B2 优先权日:2018-11-19 标 题 :Reconstituted HDL nanoparticles for delivery of radioactive agents and uses thereof 发明人:LACKO ANDRAS G; PROKAI LASZLO; ISAAC-OLIVÉ KEILA 权利人:UNIV OF NORTH TEXAS HEALTH SCIENCE CENTER; THE AUTONOMOUS UNIV OF THE STATE OF MEXICO 摘要: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.

The size- and shape-specific gold nanostructure materials prepared by the present invention may find use as: highly conductive interconnections for single-electron transistors, catalysts for the oxidation of carbon monoxide; biological and chemical sensors; and as contrasting agents for electron microscopic and medical imaging applications.
专利号:WO-0120995-A9 优先权日:1999-09-23 标题:Compounds directed against pilus biogenesis and activity in pathogenic bacteria; methods and compositions for synthesis thereof 发明人:KIHLBERG JAN; LARSSON ANDREAS; SVENSSON ANETTE; FEX TOMAS; HULTGREN SCOTT J; PINKNER JERRY 权利人:UNIV WASHINGTON; KIHLBERG JAN; LARSSON ANDREAS; SVENSSON ANETTE; FEX TOMAS; HULTGREN SCOTT J; PINKNER JERRY 摘要:Many Gram-negative pathogens assemble adhesive structures on their surfaces that allow them to colonize host tissues and cause disease. Novel compositions which inhibit or prevent the formation of a pilus chaperone-subunit complex are disclosed. Interfering with the function of the pili chaperone negatively affects the chaperone/usher pathway which is one molecular mechanism by which Gram-negative bacteria assemble adhesive pili structures and thus prevent or inhibit pilus assembly. Also provided are methods for the treatment or prevention of diseases caused by tissue-adhering pilus-forming bacteria by inhibiting the function of pilus chaperones. Also provided are pharmaceutical preparations capable of inhibiting or preventing the formation of a pilus chaperone-subunit complex. Also provided are methods of synthesizing the N-substituted amino acid compounds and compounds useful for the synthesis thereof. In particular, novel fluorinated linker compounds and methods of synthesis are provided. Methods for using the fluorinated linker compounds in methods of solid-phase synthesis of the N-substituted amino acid compounds are also disclosed.
