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.

Research Applications

Mitochondrial ETC Bypass

NADH→MB→cytochrome c — Complex I/III bypass for mitochondrial rescue

Cognitive Enhancement

Low-dose cognitive effects — memory and attention in rodent models

Alzheimer’s/Tau Research

Tau aggregation inhibition — Alzheimer’s disease models

Mitochondrial Rescue

ETC dysfunction models — rotenone/antimycin Complex I/III blockade rescue

NO/cGMP Inhibition

Guanylate cyclase inhibition — NO research and vasodilation studies
