A Computer Program To Predict Optimal Sites on Protein Sequences for Production of Peptide-Directed Antibodies (NHLBI AbDesigner)

Description of Technology: The invention offered for licensing is a computer program called “NHLBI AbDesigner” that allows the user to input a unique identifier for an individual mammalian protein to be analyzed in order to find out what short peptides in its amino sequence would most likely result in a strong immunogenic response when injected into a research animal. The software displays standard predictors of immunogenicity and antigenicity in easy-to-view heat maps and also allows users to choose peptides most likely to elicit antibodies that are specific to said protein. The computer code is written in Java and would be made available in the form of jar files.

Nanoparticle Probes and Mid-Infrared Chemical Imaging for DNA Microarray Detection

Description of Technology: The technology offered for licensing is a faster, more flexible, cost-effective microarray visualization. The invention describes and claims the mid-infrared chemical imaging (IRCI) to detect nanostructure-based DNA microarrays, which can be utilized in the life science research arena to examine gene expression and single nucleotide polymorphisms (SNPs), as well as to characterize entire genomes. The IRCI improves the signal-to-noise ratio (SNR) obtained for hybridized microarrayed spots compared to the commonly used fluorescence detection method. The improved method of this invention results in the sensitivity and precision for detecting pathogenic bacterial genes and can be utilized to detect low-expressing genes which cannot be identified by fluorescent-based DNA microarrays. Furthermore, the automated IRCI systems can also be fabricated for the dedicated detection of other (protein, tissue, biochemical, or chemical) microarrays.

Applications: DNA microarrays can be applied to the areas of environmental sciences, agriculture research, bio-defense, diagnostics, forensics, pharmacogenomics and toxicogenomics.

Advantages: The invention provides a cost-effective, faster, more flexible, and less labor intensive microarray technology.

Development Status:

  • The invention is fully developed.
  • Need to develop a commercialized kit and protocol.

Inventors: Magdi M. Mossoba, et al. (FDA).

Patent Status: U.S. Provisional Application No. 61/395,635 filed 15 Oct 2010 (HHS Reference No. E-127-2010/0-US-01).

Licensing Status: Available for licensing.

Fluoroquinolone Derivatives as Inhibitors of Human Tyrosyl-DNA Phosphodiesterase (Tdp1)

Description of Technology: Chemotherapy can provide therapeutic benefits in many cancer patients, but it often ultimately fails to cure the disease since cancer cells can become resistant to the chemotherapeutic agent. To overcome these limitations, additional strategies are needed to restore or amplify the effect of antitumor agents. Tyrosyl-DNA phosphodiesterase 1 (Tdp1) is a DNA repair enzyme involved in the repair of DNA lesions created when the activity of the Topoisomerase 1 (Top1) is inhibited. Tdp1 has been regarded as a potential therapeutic co-target of Top1 in that it seemingly counteracts the effects of Top1 inhibitors, such as camptothecin. By reducing the repair of Top1-DNA lesions, Tdp1 inhibitors have the potential to augment the anticancer activity of Top1 inhibitors.

The NIH investigators discovered fluoroquinolone derivatives as specific Tdp1 inhibitors that could potentiate the pharmacological action of Top1 inhibitors, which are currently used in cancer treatment. The instant invention discloses a method of treating cancers with a therapeutically effective amount of a Top1 inhibitor, and a fluoroquinolone derivative that inhibits Tdp1 activity.

Applications and Market:

  • This invention may provide a new combination of drugs to target various cancers for treatment.
  • Cancer is the second leading cause of death in the U.S. The National Cancer Institute estimates the overall annual costs for cancer in the U.S. at $107 billion; development of more effective cancer therapies is always in high demand.

Development Status: Pre-clinical stage of development.

HMG3 for Detecting and Treating Diabetes

Description of Technology: This invention relates to the use of High Mobility Group N 3 (HMGN3) as a marker for detecting diabetes and as a therapeutic agent for treating diabetes.

Diabetes is disabling largely because commonly available anti-diabetic drugs do not adequately control blood sugar levels to completely prevent the occurrence of high and low blood sugar levels. Inappropriate blood sugar levels can be toxic and can cause long-term complications including renopathy, retinopathy, neuropathy and peripheral vascular disease. Those with diabetes are also at risk for developing related conditions such as obesity, hypertension, heart disease and hyperlipidemia.

This invention relates to the discovery that reduced expression of HMGN3 (also called TRIP7) gives rise to elevated blood glucose levels, reduced serum insulin levels and impaired glucose tolerance.

Applications: Diagnostic and therapeutic for diabetes.

Development Status: Early stage.

Molecular Motors Powered by Proteins

Description of Technology: The technology available for licensing and commercial development relates to molecular motors powered by proteins. Some implementations describe a molecular motor in which multiple concentric cylinders or nested cones rotate around a common longitudinal axis. Opposing complementary surfaces of the cylinders or cones are coated with complementary motor protein pairs, such as actin and myosin. The actin and myosin interact with one another in the presence of ATP to rotate the cylinders or cones relative to one another, and this rotational energy is harnessed to produce work. Speed of movement is controlled by the concentration of ATP and the number of nested cylinders or cones. The length of the cylinders or cones can also be used to control the power generated by the motor.

Another configuration forms the motor out of a set of stacked disks, much like CDs on a spindle. The advantage of this form is extreme simplicity of construction compared to the nested cylinders or cones. In yet another configuration, which has aspects of both of the previous forms, the surfaces are broken into annular rings in order to overcome that the inner surfaces rotate at a different rate than the outer surfaces. This belt form may ultimately be used in molecular manufacturing.


  • Supplying power to prosthetic implants and other medical devices without external power sources.
  • Many other applications that could use a motor in other biotechnological areas, in addition to the medical applications.
  • The inventions can be implemented on either a microscopic or macroscopic scale.

Development Status: Very early stage of development.
