Mice Genetically Deficient in the Chemoattractant Receptor FPR (Formyl Peptide Receptor)

Description of Invention: The present research tool is a knockout mouse model (FPR-/-) that lacks the high affinity N-formylpeptide receptor (FPR), created by targeted gene disruption.

N-formylpeptides derive from bacterial and mitochondrial proteins, and bind to specific receptors on mammalian phagocytes. Since binding induces chemotaxis and activation of phagocytes in vitro, it has been postulated that N-formylpeptide receptor signaling in vivo may be important in antibacterial host defense, although direct proof has been lacking. The inventors have found that FPR-/- mice have no obvious developmental defects and do not develop spontaneous infection when derived in specific pathogen-free conditions. This suggests that, under these conditions, FPR is dispensable. However, when challenged with L. monocytogenes, FPR-deficient mice have accelerated mortality and increased bacterial burden in liver and spleen early after infection, which suggests a role for FPR in host defense, specifically through regulation of innate immunity.

Applications and Modality: New mouse model to study antibacterial host defense.

Market: Research tool useful for innate immunity studies.

Development Status: The technology is a research tool.

Inventors: Philip Murphy and Ji-Liang Gao (NIAID).

Patent Status: HHS Reference No. E-258-2007/0—Research Tool.

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

Description of Technology: Tyrosyl-DNA phosphodiesterase (Tdp1) is an enzyme that repairs topoisomerase I (Top1)-mediated DNA damage induced by chemotherapeutic agents and ubiquitous DNA lesions that interfere with transcription. The current technology are steroid derivatives that human inhibit Tdp1.

Currently, there are various types of Top1 inhibitors used in chemotherapy, e.g., camptothecin. However, Tdp1 inhibitors are expected to be effective in combination therapy with Top1 inhibitors for the treatment of cancers. Combining Tdp1 inhibitors with Top1 inhibitors would allow Tdp1 to potentiate the antiproliferative activity of Top1 inhibitors. In addition to Tdp1's effect on Top1, Tdp1 inhibitors can also exhibit antitumor activity independently, as tumors are shown to Start Printed Page 39633have excess free radicals, and Tdp1 repairs DNA damage by oxygen radicals.

Applications and Modality: It is anticipated that Tdp1 inhibitors in association with Top1 inhibitors can have selective activity toward tumor tissues. Tdp1 inhibitors may exhibit antitumor activity by themselves because tumors have excess free radicals.

Market: 600,000 deaths from cancer related diseases were estimated in 2006. In 2006, cancer drug sales were estimated to be $25 billion.

Development Status: The technology is currently in the pre-clinical stage of development.

Inventors: Yves Pommier et al. (NCI).

Relevant Publication: A manuscript directly related to the above technology will be available as soon as it is accepted for publication.

Patent Status: U.S. Provisional Application No. 60/921,980 filed 05 Apr 2007 (HHS Reference No. E-130-2007/0-US-01).

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