DNP, mitochondrial uncoupling, and neuroprotection: A little dab’ll do ya

Recent findings have elucidated roles for mitochondrial uncoupling proteins (UCPs) in neuronal plasticity and resistance tometabolic and oxidative stress. UCPs are induced by bioenergetic challenges such as caloric restriction and exercise and may protect neurons against dysfunction and degeneration. The pharmacological uncoupler 2,4-dinitrophenol (DNP), which was once prescribed to >100,000 people as a treatment for obesity, stimulates several adaptive cellular stress-response signaling pathways in neurons including those involving the brain-derived neurotrophic factor (BDNF), the transcription factor cyclic AMP response element-binding protein (CREB), and autophagy. Preclinical data show that low doses of DNP can protect neurons and improve functional outcome in animal models of Alzheimer’s and Parkinson’s diseases, epilepsy, and cerebral ischemic stroke. Repurposing of DNP and the development of novel uncoupling agents with hormeticmechanisms of action provide opportunities for new breakthrough therapeutic interventions in a range of acute and chronic insidious neurodegenerative/neuromuscular conditions, all paradoxically at body weight–preserving doses.

About Mitochon Pharmaceuticals
Mitochon was founded in 2014 with the mission to develop treatments for insidious diseases through the modulation of mitochondrial physiology, with applications to neurodegeneration, neuromuscular, and developmental diseases. Mitochon’s lead programs, MP101 and MP201, specifically harnesses the power of the mitochondria to provide broad neural protection. These compounds elicit mild increases in energy expenditure that result in strengthening cellular survival—similar to the positive effects seen with fasting and exercise. These compounds also induce an important neurotrophin, Brain Derived Neurotrophic Factor (BDNF), involved in cognition and neural growth. Mitochon is supported by Ben Franklin Technology Partners Southeastern PA, an initiative of the Pennsylvania Department of Community and Economic Development funded by the Ben Franklin Technology Development Authority.
