What is Methylene Blue?

Methylene Blue is a phenothiazine dye with multiple pharmacological mechanisms: (1) mitochondrial electron carrier — bypasses Complex I-III by accepting electrons from NADH and donating to cytochrome c, rescuing mitochondrial dysfunction; (2) weak MAO inhibitor; (3) guanylate cyclase inhibitor; (4) tau aggregation inhibitor (Alzheimer’s research). CAS 61-73-4.
