Thioxothiazolidinone Derivatives—A Novel Class of Anti Cancer Agents

Description of Technology: The invention provides for a novel class of heterocyclic compounds (i.e. thioxothiazolidinone derivatives) that exhibit anticancer activity in a unique mechanism. More specifically, the compounds of the invention act as inhibitors of the enzyme human tyrosyl DNA phosphodiesterase1 (Tdp1), a DNA repair enzyme involved in topoisomerase1 (Top1) mediated DNA damage, such as damage induced by the Top1 inhibitors and chemotherapeutic agents, camptothecins. As such, these compounds can serve as potentiators of camptothecins. The experimental data indeed point at a synergistic effect achieved in a combination therapy of the thioxothiazolidinone derivatives of the invention and the established anticancer agents camptothecins. Moreover, due to this synergistic effect, a lower therapeutic dose of the latter may be needed, resulting in reduced side effects. In addition, it is possible that the Tdp1 inhibitors of the invention may be effective as anti tumor agents on their own. This is based on the fact that Tdp1 is involved also in repairing DNA damage resulting from oxygen radicals, and the observation that tumors contain excess free radicals.

Potential Commercial Applications

  • Effective cancer therapy in combination with camptothecins.
  • Cancer therapy as standalone anti cancer agents.

Competitive Advantages: The compounds of the invention act in unique mechanism that can enhance the therapeutic efficacy of the anticancer drugs camptothecins, and at the same time can serve as standalone anticancer agents.

Development Stage: In vitro data available.

Monospecific and Bispecific Human Monoclonal Antibodies Targeting IGF-II

Description of Technology: The type 1 insulin-like growth factor (IGF) receptor (IGF1R) is over-expressed by many tumors and mediates proliferation, motility, and protection from apoptosis. Agents that inhibit IGF1R expression or function can potentially block tumor growth and metastasis. Its major ligands, IGF-I, and IGF-II are over-expressed by multiple tumor types. Previous studies indicate that inhibition of IGF-I, and/or IGF-II binding to its cognizant receptor negatively modulates signal transduction through the IGF pathway and concomitant cell proliferation and growth. Therefore, use of humanized or fully human antibodies against IGFs represents a valid approach to inhibit tumor growth. The present invention discloses two monoclonal antibodies, designated m610.27 and m630, and a bispecific monoclonal antibody, m660, generated by linking domains from m610.27 and m630. All three antibodies display high affinities for IGF-I and IGF-II in the pM to nM range. The antibodies inhibited signal transduction mediated by the IGF-1R interaction with IGF-I and IGF-II and blocked phosphorylation of IGF-IR and the insulin receptor. m610.27 and m630 are the first pair of human antibodies that target nonoverlapping epitopes on IGF-II. All three antibodies in an IgG1 or IgG1-like format could lead to irreversible elimination of IGF-II from circulation making it a viable candidate for cancer treatment.

Potential Commercial Applications

  • Therapeutic for the treatment of various human diseases associated with aberrant cell growth and motility such as breast, prostate, and leukemia cancers.
  • Research reagent to study IGF-I and/or IGF-II binding and its association with tumor growth.

Competitive Advantages

  • m610.27 and m630 are the first characterized antibodies that target nonoverlapping epitopes on IGF-II.
  • m660 was generated from two domains; one each from m610.27 and m630.
  • Small size of the m610.27 and m630 domains prevent overlapping in binding to IGF-II.

Development Stage

  • Pre-clinical.
  • In vitro data available.

Genetic Interactions That Predict Attention Deficit Hyperactivity Disorder Outcome and Severity

Description of Technology: Genotyping of attention deficit hyperactivity disorder (ADHD) linked chromosomal regions containing single nucleotide polymorphisms (SNPs) was used by researchers at the National Human Genome Research Institute (NHGRI) to discover gene interactions that increase the risk of developing ADHD and predict ADHD severity.

NHGRI researchers discovered an ADHD linked gene interaction between the latrophilin 3 (LPHN3) gene and a haplotype on chromosome 11q that contains the gene coding for the dopamine receptor D2 (DRD2) and neural cell adhesion molecule 1 (NCAM1). In a similar invention, mutations in LPHN3 were shown to increase the risk of developing ADHD (HHS E-312-2006, TAB 1504). Expanding on those findings, this invention describes an interaction between LPHN3 and 11q that not only doubles the risk of developing ADHD, but also the severity of ADHD. Furthermore, the LPHN3-11q interaction correlates with patient response to therapeutic treatments.

In summary, this invention can be used to develop biomarkers for determining susceptibility to and severity of ADHD, as well as, developing theranostic assays for determining prognosis of ADHD treatments. In addition, signaling pathways delineated from these genetic sites can be used to develop better ADHD therapeutics.

Potential Commercial Applications

  • Biomarkers for ADHD susceptibility and severity.
  • Prognostic assays.
  • Personalized treatment options.

Competitive Advantages: Improved prediction of ADHD susceptibility, severity, and possibly patient response to treatment.

Development Stage

  • Early-stage.
  • In vivo data available (human).

Modulating Autophagy as a Treatment for Lysosomal Storage Diseases

Description of Technology: Researchers at NIAMS have developed a technology for treatment of lysosomal storage diseases by inhibition of autophagy. Pompe disease is an example of a genetic lysosomal storage disease caused by a reduction or absence of acid alpha-glucosidase (GAA). Patients with Pompe disease have a lysosomal buildup of glycogen in cardiac and skeletal muscle cells and severe cardiomyopathy and skeletal muscle myopathy. Treatment of Pompe disease by GAA enzyme replacement therapy is quite ineffective for the skeletal muscle myopathy. Skeletal muscle resistance to therapy is associated with increased cellular buildup of autophagic debris. Inactivation of autophagy results in effective GAA replacement therapy and a reduction in glycogen back to normal levels. This technology provides a novel approach for the treatment of Pompe disease as well as other diseases where autophagy is a critical contributor to disease development.

Potential Commercial Applications

  • Development of tools for autophagy suppression and treatment of a variety of diseases.
  • Development of chemical inhibitors of autophagy.
  • Development of animal models to study lysosomal storage diseases.

Competitive Advantages

  • This technology is the first use of autophagy disablement to reverse an intracellular pathology.
  • More effective than enzyme replacement therapy alone for the treatment of the lysosomal storage disease, Pompe disease.

Development Stage: In vivo data available (animal).
