Arsenical Compounds as Therapeutics for Inflammatory Diseases

Description of Technology: FDA approved Arsenic trioxide (Trisenox or As2 O3) and other arsenical compounds for treatment of acute inflammatory conditions have been shown to be anti-inflammasome therapies. Inflammasomes are large cytoplasmic multi-protein complexes that form in response to intracellular danger signals and play a key role in many infections by controlling the innate immune response. Inflammasome activation has been implicated in metabolic disorders, such as diabetes, and inflammatory diseases, such as gout, arthritis, and cholesterol-associated atherosclerosis. The technology relates to arsenical compounds that inhibit a number of inflammasomes, including the Nlrpl, Nlrp3 and Naip5/Nlrc4, primarily by acting as an inhibitor of caspase-1 activity in innate immune cells (macrophages). It was shown that arsenical compounds induce a cellular condition which inhibits both the autoproteolytic activity of caspase-1, as well as its ability to cleave cytokine substrates. Further, it was shown that the inhibition does not occur through direct modification or inhibition of the caspase-1 enzyme, but rather through induction of a cellular environment inhibitory to its activity. Efficacy in inhibiting immune cell recruitment in a mouse model of gout has been demonstrated. The arsenicals have potential as treatment for a variety of inflammatory conditions.

Potential Commercial Applications: Therapeutics for rheumatoid arthritis, gout, colitis and various inflammatory skin diseases.

Competitive Advantages: These FDA-approved compounds have potential off-target use for treatment of acute inflammatory conditions shown to be responsive to anti-inflammasome therapies.

A Novel HIV-1 Drug Resistant Integrase Inhibitor

Description of Technology: The subject invention describes a novel and highly potent inhibitor of HIV-1 integrase (IN) that has high efficacy against the major forms of Raltegravir-resistant mutant forms of IN. Thus, this IN inhibitor can be developed as a therapeutic for patients who have developed resistance to current IN inhibitors, such as Raltegravir and Elvitegravir.

Potential Commercial Applications: HIV therapeutic.

Competitive Advantages:

  • High efficacy against the major forms of Raltegravir-resistant mutant forms of IN in in vitro and whole cell assays.
  • An HIV therapeutic for patients resistant to current IN inhibitors.

Development Stage:

  • Early-stage
  • In vitro data available

Potent and Selective Analogues of Modafinil and Uses Thereof

Description of Technology: This invention describes novel analogues of modafinil, a wake-promoting agent that has been used to treat narcolepsy and other sleep disorders.

Modafinil has attracted attention for the treatment of cognitive dysfunction in disorders such as attention-deficit/hyperactivity disorder (ADHD) as well as cocaine and methamphetamine dependence. However, modafinil has relatively low affinity for binding to the dopamine transporter (DAT) to block dopamine reuptake, and is water-insoluble, thus requiring large doses to achieve pharmacological effects.

Investigators at the National Institute of Drug Abuse have synthesized a series of modafinil analogues that have higher affinity for the dopamine (DAT), serotonin (SERT) and/or norepinephrine (NET) transporters and improved water solubility. These novel analogues present the advantage of higher potency, which may translate into lower effective doses and better bioavailability over modafinil.

Potential Commercial Applications:

  • Therapeutic agent for substance abuse (such as nicotine, cocaine, methamphetamine, opioids)
  • Therapeutic agent for attention/cognitive disorders (such as ADHD)
  • Therapeutic agent for sleep disorders

Competitive Advantages:

  • Higher affinity for monoamine transporters (DAT, SERT, and NET)
  • Lower effective doses
  • Better bioavailability,
  • Improved water solubility

Development Stage: Early-stage

Translocator Protein 18 kDa PET Radioligands With High Affinities Regardless of Genotype

Description of Technology: This technology relates to a group of Translocator protein 18 kDa (TSPO) radioligands for Positron Emission Tomography (PET) that are specific and accurate, regardless of genotype. TSPO is a mitochondrial protein expressed in inflammatory cells, which is a marker for neuroinflammation. Neuroinflammation is symptomatic of many neuropsychiatric and neurodegenerative disorders, such as multiple sclerosis, stroke, epilepsy, dementia, and traumatic brain injuries. Monitoring and quantifying TSPO 18 kDa with radioligands in PET may have clinical application in understanding, diagnosing and treating many neuropsychiatric disorders. However, current TSPO 18 kDa radioligands either lack specificity or, due to TSPO polymorphisms, have highly variable inter-subject sensitivities depending on genotype. These new ligands are specific and accurate, regardless of genotype, allowing simplified interpretation and quantification of the binding signal.

Potential Commercial Applications: Biomarker or diagnostic for neuroinflammation

Competitive Advantages: Specific and accurate, regardless of genotype

Development Stage:

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