Epstein-Barr Virus (EBV) is the causative agent of infectious mononucleosis and is associated with certain types of cancers, such as Hodgkin's lymphoma, Burkitt's lymphoma, gastric carcinoma, and nasopharyngeal carcinoma. There are currently no vaccines against EBV on the market and there is only supportive treatment available for EBV infection.

This technology includes the development and use of small molecule activators of pyruvate kinase (PK) for the treatment of inherited nonspherocytic hemolytic anemia, including PK deficiency. PK deficiency is caused by an inherited deficiency in an enzyme that reduces the lifespan of red blood cells. More than 150 unique mutations have been identified in the PK gene that lead to decreased activity in this essential enzyme in the glycolytic pathway. The prematurely lysed red blood cells can lead to jaundice, splenomegaly, and a hemolytic anemia.

This technology includes the synthesis and use of novel PI3K and HDAC dual inhibitors for the treatment of several cancers. Phosphatidylinositol 3-kinase (PI3K) is activated in many human cancers, and inhibition of these kinases is an established cancer treatment. Histone deacetylases (HDACs) are key regulators of the cell cycle that function through regulating expression of tumor suppressors (p21 and p27), c-Myc and cyclin D1. HDAC inhibition is an emerging therapeutic approach for the treatment of several cancers.

This technology includes the identification and use of a combination therapy consisting of human recombinant N-acetylgalactosamine-6-sulfate sulfatase (hrGALNS) and the pharmacological chaperone compounds Ezetimibe and Pranlukast for the treatment of Mucopolysaccharidosis Type IVA (MPS IVA). MPS IVA is a rare disease caused by mutations in the gene encoding the lysosomal enzyme N-acetylgalactosamine-6-sulfate sulfatase (GALNS). Currently, hematopoietic stem cell transplantation (HSCT) and enzyme replacement therapy (ERT) are available for patients with MPS IVA.

This technology includes the use of the small molecule metarrestin (ML246) for the treatment of several types of pancreatic cancer. A subcellular structure called the perinucleolar compartment (PNC) is frequently found in metastatic tumors and cancer stem cells. Reduction of PNC prevalence followed by medicinal chemistry was used to identify metarrestin as a compound that reduces PNC prevalence without significantly impacting cell viability. In vitro and in vivo animal work have demonstrated desirable pharmacokinetic properties as well as a reduction in metastatic burden and extended survival.

Local inflammation processes are crucially important in the host defense against pathogens and for successful immunization because proinflammatory cytokines are necessary for initiation and propagation of an immune response. However, normal inflammatory responses are eventually terminated by physiological termination mechanisms, thereby limiting the strength and duration of immune responses, especially to weak antigens. The inventors have shown that adenosine A2a and A3a receptors play a critical role in down-regulation of inflammation in vivo.

Homocystinuria (HCU), a group of inherited disorders, causes symptoms ranging from failure to thrive and developmental delays in infants or young children to abnormal blood clots with onset in adults.1 Approximately 1 in 200,000 to 335,000 people have HCU globally.2

Vitamin D receptor (VDR) is a nuclear receptor that is activated by calcitriol, the active form of vitamin D. It is best known for regulating dietary calcium uptake necessary for bone growth, but it also affects cell proliferation and differentiation. Therefore, it was thought that treatment with calcitriol or its derivatives could be useful to treat the uncontrolled proliferation typical of cancer cells. However, this approach has been unsuccessful to date because it leads to toxic levels of calcium in the blood.

The claimed invention provides highly specific and sensitive methods for in vivo, in vitro, or ex vivo imaging of specific extracellular protease activity using an anthrax binary toxin system. The system targets cells that express extracellular proteases of interest. Such a system would be highly useful since various studies have demonstrated a positive correlation between the activity of extracellular proteases and various diseases and undesirable physiological conditions.

Adeno-associated virus (AAV) is being developed for gene therapy applications. This virus type presents several advantages over alternate vectors for therapeutic gene delivery. AAV is not considered pathogenic and transduces stably dividing and non-dividing cells. AAV also shows good serotype specificity to various cell types for targeted gene delivery.
