Species-Independent A3 Adenosine Receptor Agonists

Description of Technology: The A3 adenosine receptor (A3AR) subtype has been linked with helping protect the heart from ischemia, controlling inflammation, and regulating cell proliferation. Agonists of the human A3AR subtype have been described; however, they lack selectivity for the corresponding receptor of the mouse. This poses a problem for clinical development because animal model testing is important for pre-clinical validation of drug function. Consequently, a novel agonist was made that is selective for the mouse A3AR while retaining selectivity for the human receptor. This innovation should facilitate moving A3 agonists into the clinical phase of drug development with confidence.

This invention claims species-independent agonists of A3AR, specifically (N)-methanocarba adenine nucleosides. In addition, it describes pharmaceutical compositions comprising such nucleosides, and methods of use such as administering an effective amount to a mammal.

Applications: cardiac arrhythmias or ischemia; inflammation; stroke; diabetes; asthma; cancer.

Market: Heart disease and cancer are the leading causes of death for both women and men in the United States despite many advances in drug development. Hence, there is a need for drugs with unique mechanism of action. It is noteworthy that the first synthetic adenosine receptor agonist has recently been approved for use in humans.

Development Status: Research quantities of compounds have been synthesized and tested for receptor selectivity.

Inventors: Kenneth A. Jacobson and Artem Melman (NIDDK).

Patent Status: U.S. Provisional Application No. 61/040,985 filed 31 Mar 2008 (HHS Reference No. E-140-2008/0-US-01).

Licensing Status: Available for exclusive or non-exclusive licensing.

Fluorescent Cell Lines for Detection of DNA Damage

Description of Technology: The Enhanced Level of Genomic instability 1 (ELG1) protein suppresses genomic instability caused by DNA damage. Cell lines for studying human ELG1 (hELG1) have been established that stably express a fusion protein combining hELG1 and either Green Fluorescent Protein (GFP) or Cyan Fluorescent Protein (CFP). It has been shown that the fluorescent hELG1 is an excellent reporter for DNA damage within the cell, with increased hELG1 localization to the cell nucleus upon exposure to a genotoxin. Therefore, these cell lines may have utility as a screening tool to detect genotoxic agents.

Available for licensing are the RPE cell line (immortalized normal retinal pigment epithelial cells) stably expressing hELG1-CFP, and the U2OS cell line (human osteosarcoma cells) stably expressing hELG1-GFP.

Applications: High-sensitivity screening tool for genotoxic agents.

Inventor: Kyungjae Myung (NHGRI).

Relevant Publication: In preparation.

Patent Status: DHHS Reference No. E-108-2008/0—Research Tool. Patent protection is not being pursued for this technology.

Licensing Status: Available for non-exclusive licensing.
