Delta Tocopherol for the Treatment of Lysosomal Storage Disorders

   Description of Technology: Delta Tocopherol is identified as a novel therapeutic to treat lysosomal disorders characterized by defective cellular cholesterol and other lipid trafficking and storage. Currently, there is no treatment for many of Lysosomal Storage Disorders. In some cases, such as Gaucher disease, enzyme replacement therapy and substrate deduction treatment are available with very high cost (over $100,000 per patient per year). NIH investigators have identified an unexpected and previously unrecognized use for delta tocopherol, which is a form of vitamin E, in the treatment of diseases and conditions related to lysosomal storage disorders. Scientists at the National Center for Advancing Translational Sciences, NIH discovered a clear difference between the effects of delta-tocopherol and alpha tocopherol on the cell-based disease models of Niemann Pick C (NPC) disease. They found that while delta-tocopherol significantly reduced the cholesterol accumulation in NPC cells and reduced the size of enlarged lysosomes, alpha-tocopherol only showed weak effects in the same cells.

   The present invention can be used to develop new therapies involving delta-tocopherol to treat lysosomal disorders, such as Niemann-Pick type C disease, Mucopolysaccharidoses disorder, and Neuronal Ceroid Lipofuscinoses. This invention provides potential novel methods for the modulation of cholesterol and other lipids' recycling. It may be also possible to use delta-tocopherol for the reduction of the size of enlarged lysosomes caused by accumulation of lipids and macromolecules.

   Potential Commercial Applications:

    * Therapeutics for lysosomal disorders

    * Therapeutics for Niemann-Pick type C disease

   Competitive Advantages: delta-tocopherol is a novel lead compound for drug development to treat a variety of lysosomal storage diseases characterized by lipid/macromolecule accumulation and defective lipid trafficking.

   Development Stage:

    * Early-stage

    * In vitro data available

18F-Labeled Calcofluor Derivatives for PET Imaging and Diagnosis of Aspergillus Infection

   Description of Technology: Aspergillus is a common fungal lung infection with high mortality rates in immune compromised patients. The inability to diagnose this infection impedes treatment. Blood based diagnostic tests for this infection lack sensitivity and specificity due to cross reactivity. Other methods of diagnosis are invasive and labor intensive. The ability to accurately and non-invasively diagnose infection in Aspergillus immune compromised populations may greatly improve treatment and lower mortality rates. This technology uses 18F-labeled calcofluor derivatives for positron emission tomography (PET) imaging of filamentous fungal infections. 18F-labeled calcofluor derivatives have low toxicity, high binding specificity to Aspergillus species due to uptake by Aspergillus -specific siderphore system, and low binding affinity to patient tissue. These compounds may be used for rapid and accurate PET diagnostic imaging of infection by species of Aspergillus.

   Potential Commercial Applications: Diagnosis of Aspergillus infection.

   Competitive Advantages: Non-invasive, low toxicity, specific for Aspergillus.

   Development Stage: In vivo data available (animal).

Nucleic Acid Nanoparticles for Triggering RNA Interference

   Description of Technology: RNA interference (RNAi) is a naturally occurring cellular post-transcriptional gene regulation process that utilizes small double-stranded RNAs to trigger and guide gene silencing. By introducing synthetic RNA duplexes called small-interfering RNAs (siRNAs), we can harness the RNAi machinery for therapeutic gene control and the treatment of various diseases.

   The present invention discloses RNA, RNA-DNA, DNA-RNA, hybrid nanocubes consisting of a DNA or RNA core (composed of six strands) with attached RNA or DNA hybrid duplexes. The nanocubes can induce the reassociation of the RNA duplexes, which can then be processed by the human recombinant Dicer enzyme, thus activating RNAi. This technology opens a new route for the development of "smart" nucleic acid based nanoparticles for a wide range of biomedical applications. Immune responses can be controlled by altering the composition of the particles.

   Potential Commercial Applications:

    * Treatment for various diseases

    * Clinical research

    * Basic research

   Competitive Advantages:

    * Low cytotoxicity

    * Chemical stability

    * More specificity

    * Controlled activation

    * Multiple targets

    * Visualization
