alpha-synuclein / mitochondrial ATP

Class

restoration small molecule

Alpha-synuclein is a small neuronal protein whose misfolding and aggregation into insoluble fibrils is a hallmark of a group of neurodegenerative disorders called synucleinopathies, including Parkinson's disease and related conditions. Normally, alpha-synuclein helps regulate synaptic vesicle trafficking, but when it misfolds it forms toxic oligomers and fibrils that impair cellular function, including mitochondrial activity. Mitochondria are the organelles responsible for producing adenosine triphosphate (ATP), the cell's primary energy currency. In neurons affected by synucleinopathies, mitochondrial ATP production is often compromised, both as a consequence of alpha-synuclein-related toxicity and, in some cases, as an independent driver that promotes further aggregation. This creates a bidirectional relationship in which energy failure and protein misfolding reinforce one another. A therapeutic strategy addressing both processes together, rather than either in isolation, aims to interrupt this cycle by restoring cellular energy supply while limiting the burden of misfolded protein. Because neurons are highly energy-dependent and particularly vulnerable to mitochondrial dysfunction, mechanisms of this kind are being explored broadly across neurodegenerative diseases where energy failure and protein aggregation coexist, with Parkinson's disease being the most prominent example.
