Hesperetin Therapy for Metabolic Syndrome and Insulin Resistance

Description of Technology: Hesperidin is a flavonoid compound found in citrus fruits. Large epidemiological studies have linked increased consumption of flavonoid-rich foods, such as citrus, with reduced cardiovascular morbidity and mortality. Investigators from the National Center for Complementary and Alternative Medicine have demonstrated that administration of oral hesperidin to patients with metabolic syndrome attenuates biomarkers of inflammation and improves blood vessel relaxation, lipid cholesterol profiles, and insulin sensitivity when compared to controls. Thus, hesperidin and its active aglycone form, hesperetin, may be effective agents for the treatment of diabetes, obesity, metabolic syndrome, dyslipidemias, and their cardiovascular complications including hypertension, atherosclerosis, coronary heart disease, and stroke. This technology discloses methods for using a hesperetin composition to treat metabolic syndrome and insulin resistance.

Applications: Therapeutics for metabolic syndrome and insulin resistance.

Development Status: Clinical trial data available.

Substituted Triazine and Purine Compounds for the Treatment of Chagas Disease and African Trypanosomiasis

Description of Technology: Parasitic protozoa are responsible for a wide variety of infections in both humans and animals. Trypanosomiasis poses health risks to millions of people across multiple countries in Africa and North and South America. Visitors to these regions, such as business travelers and tourists, are also at risk for contracting parasitic diseases. There are two types of African trypanosomiasis, also known as sleeping sickness. One type is caused by the parasite Trypanosoma brucei gambiense, and the other is caused by the parasite Trypanosoma brucei rhodesiensi. If left untreated, African sleeping sickness results in death. Chagas disease, caused by Trypanosoma cruzi (T. cruzi), affects millions of people in Mexico and South and Central America. Untreated, Chagas disease causes decreased life expectancy and can also result in death.

The subject invention covers novel triazine and purine compounds that are inhibitors of key proteases (cruzain and Rhodesian) of the parasites Trypanosoma brucei rhodesiensi and Trypanosoma cruzi, respectively.

Applications: Prophylactic and therapeutic treatment of African trypanosomiasis and Chagas disease.


  • Novel compounds against the cysteine proteases, cruzain and rhodesain.
  • Compounds possess low nanomolar inhibitory potential against cruzain and rhodesain.

Development Status: In vitro and in vivo data are available upon request and upon execution of an appropriate confidentiality agreement.

A Novel, Inhibitory Platelet Surface Protein (TREM Like Transcript, TLT-1): New Target for the Treatment of Cancer, Infectious Diseases, Cardiac Diseases, and Platelet-Associated Disorders

Description of Technology: Triggering Receptors in Myeloid Cells (TREM) recently were discovered to modulate innate and adaptive immunity. Specifically, TREM1 amplifies the response to sepsis in innate immunity by activating neutrophils and other leukocytes; and TREM2 potentiates dendritic cell maturation in adaptive immunity.

This invention describes a novel, inhibitory platelet surface protein known as TREM like Transcript (TLT-1). TLT-1 is the first inhibitory receptor discovered to reside within the TREM gene locus. Structurally, TLT-1 also possesses inhibitory domains that indicate this regulatory function. TLT-1 is highly expressed in peripheral blood platelets and may modulate many other types of myeloid cells. Additionally, the invention describes specific, human, single chain antibodies (scFvs) that recognize TLT-1.


  • This discovery implies the receptor has an important regulatory role in both innate and adaptive immunity.
  • TLT-1 is a potential therapeutic target for thrombosis and other platelet-associated disorders, as well as immune disorders, cancer, septic shock, infectious disease, stroke, heart disease, myocardial infarction, vascular disorders.
  • Detection of soluble TLT-1 in patient plasma suggests the protein is a marker of ongoing coagulopathies.
  • Defective platelet aggregation in TLT-1 null mice confirms a role for the protein in regulation of thrombosis associated with inflammation.


  • In vitro proof of concept data available—Three of the anti-TLT-1 scFvs inhibit thrombin-induced aggregation of human platelets in a dose-dependent manner.
  • Complete human origin of these antibodies suggests negligible immunogenicity and minimizes the problem of adverse immune responses in human therapy.
  • Target validation is complete. TLT-1 null mice demonstrate defects in platelet aggregation with no gross bleeding defect.

Development Status: In vitro experiments completed. Target validation with null mice completed. In vivo animal studies with scFv are currently ongoing.
