Small-Molecule Inhibitors of Human Galactokinase for the Treatment of Galactosemia and Cancers Back to Top

Description of Technology: Lactose, found in dairy products and other foods, is comprised of two simple sugars, glucose and galactose. In galactosemia, where galactose is not properly metabolized, build-up of toxic compounds, such as galactose-1-phosphate, can lead to liver disease, renal failure, cataracts, brain damage, and even death if this disorder is left untreated. Currently, the only treatment for galactosemia is elimination of lactose and galactose from the diet, but in some cases this is not sufficient to avoid long-term complications from the disorder.

This technology describes selective small-molecule inhibitors of human galactokinase, which inhibit the first step in galactose metabolism. These compounds could be used to treat galactosemia by eliminating the build-up of toxic metabolites in brain, liver and other tissues, and could form the basis for the first effective treatment for this disorder.

These inhibitors are also promising candidates for the treatment of certain cancers, such as PTEN/AKT misregulated cancers. The inventors have already shown that the inhibitors are cytotoxic for several cancer cell lines.

Potential Commercial Applications:

  • Treatment of galactosemia
  • Treatment of certain cancers, such as PTEN/AKT misregulated cancers

Competitive Advantages:

  • There is currently no effective treatment for classic galactosemia, where dietary restriction cannot prevent long-term complications in some cases.
  • Cancer therapeutics based on these inhibitors are predicted to have minimal side-effects.

Development Stage:

  • Early-stage
  • In vitro data available

The Cancer Stem Cell Finder: A Novel Reporter Construct Which Uses Transposition and Green Fluorescent Protein Expression To Identify Cancer Stem Cells Back to Top

Description of Technology: Scientists at the National Institutes of Health (NIH) have designed a novel reporter construct which can be used to identify, monitor, and allow for the manipulation of cancer stem cells (CSCs). CSCs are a subset of poorly differentiated tumor cells expressed at low frequency within a tumor and are resistant to conventional chemotherapies. CSCs have high metastatic potential and give rise to new tumors that spread cancer throughout the body. These characteristics make CSCs prime targets for developing new therapeutic agents to eradicate cancer.

The reporter construct is a novel expression vector composed of the Sleeping Beauty transposon plasmid and a Nanog promoter linked to green fluorescent protein (GFP). Nanog is a transcription factor that is overexpressed in embryonic stem (ES) cells and tumors that resemble ES cells. When introduced into a population of tumor cells, the Nanog-GFP-Sleeping Beauty transposon construct is able to integrate into tumor cell DNA via transposition. If the transposed cell is a CSC, the Nanog transcription factor overexpressed in that CSC will bind to the Nanog-promoter in the reporter construct to drive GFP expression within the cell. Thus, CSCs can be isolated based on their selective expression of the GFP label. The NIH scientists have utilized their reporter construct to identify small populations of CSCs in mouse and human breast cancer cell models.

Potential Commercial Applications:

  • Identify CSCs with high metastatic potential in patients to target with therapeutic intervention
  • Screen therapeutic drug candidates to identify their effectiveness against CSCs in comparison to more highly differentiated tumor cells
  • Investigate genes, surface proteins, and other markers responsible for CSC “stem-ness” to develop CSC diagnostics and identify therapeutic candidates to stop or reverse the properties contributing to the high metastatic potential of these cells
  • Identify transcription factors/genes activated in the tumor microenvironment that trigger metastasis

Competitive Advantages:

  • The reporter construct is validated to identify CSCs in both human and mouse tumor cell populations
  • Researchers and clinicians can monitor the “stem-ness” of a tumor cell population to predict the metastatic potential of a tumor
  • CSCs are identified in vivo in somatic cells via GFP labeling without utilizing a virus for transfection
  • CSCs can be isolated, monitored, and traced via their GFP label in both in vitro and in vivo experimentation
  • Facilitates the generation of a large quantity of CSCs for further study

Development Stage:

  • Early-stage
  • Pre-clinical
  • In vitro data available
  • In vivo data available (animal)

Genes and Autoantibodies To Diagnose and Treat Sjögren's Syndrome Back to Top

Description of Technology: Sjögren's syndrome (SS) is a chronic autoimmune disease of unknown etiology that targets salivary and lacrimal glands and may be accompanied by multi-organ systemic manifestations. To date, no specific diagnostic test has been developed for SS and, as a result, SS is often underdiagnosed and undertreated.

In order to further understand the immunopathology of SS and uncover both therapeutic and diagnostic targets, researchers at NIH compared gene expression profiles of salivary glands with severe inflammation to those with mild or no disease. Results from these studies identified target genes that were further characterized in tissues, serum and in cultured cell populations by real time PCR and protein analyses. Among the most highly expressed SS genes were genes associated with myeloid cells, including members of the mammalian chitinase family. In addition to genes, the researchers have also identified autoantibodies that have increase levels in SS patients. The gene expression levels and autoantibodies identified in the research represent both promising means for diagnosing SS earlier in disease progression as well as therapeutic targets to treat SS.

Potential Commercial Applications:

  • Diagnosis of Sjögren's syndrome
  • Treatment of Sjögren's syndrome

Competitive Advantages: The genes and autoantibodies identified in this technology may lead to one of the first diagnostic tests for Sjögren's syndrome.

Development Stage:

  • Early-stage
  • In vitro data available

Bacterially Expressed Influenza Virus Recombinant HA Proteins for Vaccine and Diagnostic Applications Back to Top

Description of Technology: Pandemic H1N1 influenza virus is a recently emergent strain of influenza virus that the World Health Organization (WHO) estimates has killed at least 14,711 people worldwide. Avian influenza viruses are emerging health threats with pandemic potential. Due to their global health implications, there has been a massive international effort to produce protective vaccines against these influenza virus strains. Currently, influenza virus vaccines are produced in chicken eggs, a production method that is disadvantaged by lengthy vaccine production times and by inability to meet large-scale, global demands.

The subject technologies are specific recombinant HA proteins from H1N1, H5N1, and other strains of influenza virus produced in bacteria. The HA proteins properly fold, form oligomers, bind fetuin, agglutinate red blood cells and induce strong neutralizing antibody titers in several in vivo animal models. The key advantages of this technology are that expression of these proteins in bacteria reduces the vaccine production time and offers the ease of scalability for global usage, an issue with current production methods. The recombinant HA proteins can also be used for diagnostic applications.

Potential Commercial Applications:

  • Vaccines for the prevention of influenza infection
  • Diagnostics for influenza virus specific antibodies

Competitive Advantages:

  • Novel vaccine candidates
  • Rapid production time
  • Ease of scalability

Development Stage:

  • In vitro data available
  • In vivo data available (animal)

Potent, Easy To Use Targeted Toxins as Anti-Tumor Agents Back to Top

Description of Technology: The invention discloses synthesis and use of novel derivatives of 2-[2'-(2-aminoethyl)-2-methyl-ethyl]-l,2-dihydro-6-methoxy-3H-dibenz-[de,h]isoquinoline-l,3-dione as targeted anti-tumor agents. The use of targeted toxin conjugates with anti-cancer antibodies, such as herceptin, is increasing. Based on a comparison with the structurally complex toxins, such as DM1, available in the market, these novel toxins are more stable in circulation, thus making the toxin-conjugates more tumor-selective and less toxic. As such, these compounds are superior alternatives to the existing toxins.

The invention describes a potent and easy to synthesize toxin that can be used for generating a variety of prodrugs. These compounds can be attached to a ligand that recognizes a receptor on cancer cells, or to a peptide that is cleaved by tumor-specific proteases. The compounds are topoisomerase inhibitors and are mechanistically different from DM1 that targets tubulin.

The structure of the toxin allows it to be modified with a peptide linker that is stable, but rapidly cleaved in lysosomes after the compound is specifically taken up by cancer cells.

Potential Commercial Applications: The compounds can be used for preparation of a variety of potent anti-cancer agents with low systemic toxicity.

Competitive Advantages:

  • Easy to prepare
  • Structural features make these compounds more stable in circulation
  • Toxin conjugates are more tumor-selective and less toxic

Development Status:

  • In vitro data available
  • In vivo data available (animal)
