SIRT2 Inhibitors as Novel Therapeutics for Myocardial Infarction and Ischemic Stroke and to Prevent Necrosis Back to Top

Description of Technology: Sirtuin 2 (SIRT2) inhibitors to reduce necrosis and, thereby, as novel therapeutics to treat ischemic stroke and myocardial infarction. Accumulating evidence indicates that programmed necrosis plays a critical role in cell death during ischemia-reperfusion. NIH investigators have shown that the NAD-dependent deacetylase SIRT2 binds constitutively to receptor-interacting protein 3 (RIP3) and that deletion or knockdown of SIRT2 prevents formation of the RIP1-RIP3 complex in mice. These investigators also found that genetic or pharmacological inhibition of SIRT2 blocks cellular necrosis induced by TNF-alpha and RIP1 is a critical target of SIRT2-dependent deacetylation. Further studies also showed that the hearts of Sirt2 -/- mice, or wild-type mice treated with a specific pharmacological inhibitor of SIRT2, show marked protection from ischemic injury. These results implicate SIRT2 as an important regulator of programmed necrosis and indicate that SIRT2 inhibitors may constitute a novel approach to protect against necrotic injuries, including ischemic stroke and myocardial infarction.

Potential Commercial Applications:

  • Novel therapeutics to protect against necrotic injuries.
  • Novel therapeutics to treat ischemic stroke and myocardial infarction.
  • Novel therapeutics to treat diseases in which necrosis is involved.

Competitive Advantages:

  • None of the currently available drugs address the necrotic damage caused due to ischemia and reperfusion.
  • Using a SIRT2 inhibitor could limit the damage caused by necrosis and contribute to accelerated recovery in patients suffering from these conditions.

Development Stage:

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

Multivalent Meningiococcal Conjugates and Methods for Preparing Conjugates Back to Top

Description of Technology: Among 13 isolated meningococcal serogroups, A, B, C, W-135 and Y are the most prevalent. There are three FDA-approved capsular polysaccharide (PS)-based vaccines, one tetravalent PS vaccine, and two tetravalent conjugate vaccines for protection against meningococcal disease caused by groups A, C, W-135 and Y Neisseria meningitidis. Group B capsular PS is similar to the PS structure expressed in certain human tissues, thus making it a poor immunogen. Furthermore, if used as a vaccine, the possibility exists of it inducing an autoimmune response. Thus, a need remains to develop additional meningococcal vaccines, particularly for group B and group X meningococcal serogroups.

This application claims immunogenic conjugates including at least one polysaccharide conjugated to a group B factor H binding protein (fHbp). Also claimed are immunogenic conjugates including at least one polysaccharide conjugated to a Neisserial surface protein A (NspA). Additionally, improved methods for preparing conjugates are claimed.

Potential Commercial Applications:

  • Multivalent meningitis vaccine
  • Research tool

Competitive Advantages:

  • Higher vaccine yield
  • More efficient conjugation method
  • Lower cost vaccines

Development Stage:

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

Enhanced Cancer Therapy Using Photoimmunotherapy (PIT) in Combination With Anti-Cancer Agents Back to Top

Description of Technology: The invention is in the field of Photoimmunotherapy (PIT). More specifically, the invention relates to antibody-fluorophore conjugates where the antibody is specific for cancer cells and the fluorophore is IR700 dye. Binding of such conjugates to targeted cancer cells followed by irradiation with near infrared light (NIR) was shown to kill cancer cells in a highly specific manner. Furthermore, the invention discloses that the therapeutic effect of the PIT conjugate is significantly enhanced by the administration of one or more anti-cancer agents following the irradiation step. This is achieved by the markedly rapid accumulation of the therapeutic agent in the PIT-treated tissue. Also provided in the invention are wearable devices that incorporate NIR light emitting diodes (LEDs) and can be used to activate the PIT conjugates.

Potential Commercial Applications: Anti-cancer therapy.

Competitive Advantages:

  • Highly specific to cancer cells
  • Do not affect surrounding normal cells
  • Negligible toxicity
  • Enhancement of therapeutic effects when administered in combination with one or more other therapeutic agents
  • Possible to follow the cell killing process in real time, using fluorescence lifetime imaging

Development Stage: In vivo data available (animal).
