What is Methylene Blue (Basic blue 9)?
Methylene blue is methylthioninium chloride, a phenothiazine dye first synthesised in 1876 and one of the oldest compounds still in active research use. It cycles between oxidised and reduced forms, which underlies both its use as a stain and its studied activity as an alternative mitochondrial electron carrier.
Methylene Blue research focus
- Redox cycling — the oxidised / reduced couple
- Alternative electron carrier — bypassing complex I/III in the respiratory chain
- Nitric oxide pathway — guanylate cyclase inhibition
- Monoamine oxidase — reported inhibitory activity
- Historical breadth — one of the longest research records of any compound
What researchers look at in Basic blue 9
- Mitochondrial oxygen consumption under complex I inhibition
- Redox potential and cycling kinetics
- Soluble guanylate cyclase activity
- MAO-A inhibition constants
- Concentration dependence — effects reverse at higher concentrations
