Methylene blue (methylthioninium chloride) is a synthetic phenothiazine dye first synthesized in the 19th century and among the most extensively characterized redox-active small molecules in the biochemical literature. It has a long history of laboratory and clinical use in areas such as methemoglobinemia and historically as an antimalarial, and remains a frequently studied compound in mitochondrial and neurodegeneration-focused research.

What is Methylene Blue?
Methylene blue is studied in laboratory research primarily for its role as an alternative electron carrier in the mitochondrial electron transport chain. Research describes methylene blue as able to accept electrons from NADH and donate them directly to cytochrome c, effectively bypassing Complex I and III activity in tested cell and tissue models — a property study authors have linked to observed changes in cellular oxygen consumption and ATP production in those models. At different concentrations, published research also describes both antioxidant and pro-oxidant behavior for the compound, a dose-dependent pattern noted repeatedly across the in vitro literature.

Research Applications
Mitochondrial & Cellular Metabolism Research
Published in vitro and animal-model research has examined methylene blue’s effect on mitochondrial respiration and cellular energy metabolism, reporting measurable changes in oxygen consumption and electron transport chain activity in tested cell lines and tissue preparations under specific dosing conditions.
Neurodegeneration-Related Models
A substantial body of preclinical research has examined methylene blue’s interaction with tau protein aggregation in cell and animal models relevant to tauopathies, along with its effects on markers of oxidative stress and mitochondrial function in neuronal cell models. Study authors describe these as laboratory findings requiring further mechanistic work rather than established clinical outcomes.
Historical Antimicrobial Research
Methylene blue has a long-documented research history as an antimalarial and antimicrobial redox agent, with in vitro and animal-model studies examining its activity against Plasmodium species and other pathogens dating back over a century.
