Nipamovir: An Affordable, Oral Treatment for HIV Infection with a High Barrier to Resistance

This technology includes an oral treatment for HIV infection. Nipamovir is a low molecular weight mercaptobenzamide derivative that is simple to produce on kilogram scale and which can be used to lower or eliminate the infectivity of HIV. Extended treatment of Simian immunodeficiency virus (SIV)-infected macaques with Nipamovir lowers the viral load by 1 log unit, and eliminates the ability of remaining virus to infect other cells. Nipamovir shows similar antiviral activity in HIV-infected human cells. There are no toxic side-effects observed in animal studies with Nipamovir.

Therapeutics for Neurodegenerative Disorders and Cancer Using Lenalidomide Analogs

Inflammatory processes associated with the over-production of tumor necrosis-alpha (TNF-alpha), a potent activator of the immune system accompany numerous neurodegenerative diseases. TNF-alpha has been validated as a drug target with the development of the inhibitors Enbrel and Remicade (fusion antibodies) as prescription medications. Both, however, are large macromolecules that require direct injection and have limited brain access.

MRI-Based Method for Characterizing Axonal Microstructure in Traumatic Brain Injury

Neurites of the central nervous system can be conceptualized as cylindrical pores with finite lengths and radii. In response to physical trauma, axons may assume a “beaded” morphology which alters their ability to conduct electrical impulses, impairing brain function. These microstructural changes are thought to underlie some of the cognitive defects observed in patients with traumatic brain injury (TBI). Current methods for characterizing traumatic brain injury (TBI) cannot provide microstructural detail on the 3-dimensional shape of axonal segments.

Immunogenic Antigen Selective Cancer Immunotherapy

Melanoma is a particularly aggressive form of cancer primarily caused by over-exposure to sunlight.  Although melanoma can strike at any age, the malignancy disproportionately impacts persons of advanced age, as these individuals often have decades of repeated exposure to harmful levels of ultraviolet radiation.  Scientists at NIH among others have clarified the link between advanced melanoma and other malignancies and expression of SPANX-B.

Engineered Biological Pacemakers

The National Institute on Aging's (NIA) Cellular Biophysics Section is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate, or commercialize biological pacemakers.

A common symptom of many heart diseases is an abnormal heart rhythm or arrhythmia. While effectively improving the lives of many patients, implantable pacemakers have significant limitations such as limited power sources, risk of infections, potential for interference from other devices, and absence of autonomic rate modulation.

Methods of Synthesis of the Ketamine Analogs (2R, 6R)-kydroxynorketamine and (2S, 6S)-hydroxynorketamine for the Treatment of Pain and other Anxiety-related Disorders

This technology includes a method for synthesizing the ketamine analogs (2R,6R)-hydroxynorketamine (HNK) and (2S,6S)-hydroxynorketamine that may be useful for the treatment of pain, depression, anxiety, and related disorders. The drug ketamine was first used as an anesthetic but was found to be an effective treatment in a range of conditions, including paint, treatment-resistant bipolar depression, and other anxiety-related disorders. However, the routine use of ketamine is hindered by unwanted side effects, including the potential for abuse.

Use of the Ketamine Metabolite (R,6R)-hydroxynorketamine in Depression

This technology includes the identification and use of a ketamine metabolite, (2R,6R)-2-amino-2-(2-chlorophenyl)-6-hydroxycyclohexanone (HNK), for the treatment of depression. Ketamine is an NMDA receptor antagonist that exerts a rapid and sustained antidepressant and anti-suicidal effect. However, even low doses of ketamine has addictive and psychomimetic effects. The downstream metabolite, (2R,6R)-HNK, does not inhibit the NMDA receptor but recapitulates the antidepressant and anti-suicidal effect of ketamine.

4-Amino-2-(piperidin-3-yl)isoindoline-1,3-diones as Anti-inflammatory Agents for Systemic Degenerative and Neurodegenerative Disorders

Summary:

The National Institute on Aging (NIA) seeks research co-development partners and/or licensees for the pre-clinical and clinical development of the compounds as anti-inflammatory therapeutics for systemic degenerative and neurodegenerative disorders.
