This podcast discusses the historical synthesis of Methylene Blue in medicine, its role in rerouting electrons and therapeutic applications, the effects and risks of Methylene Blue including decreased brain connectivity, and its potential benefits as a disinfectant and in treating respiratory chain disorders.
Methylene blue has versatile applications, including treating methemoglobinemia, Alzheimer's disease, cyanide/hydrogen sulfide poisoning, and enhancing memory.
Methylene blue acts as an MAOI, providing antidepressant and anti-anxiety effects, but has potential risks of serotonin toxicity, hypertension, and dependence.

Methylene Blue: A Synthetic Drug and Redox Reactive Dye
Methylene Blue, first synthesized in 1876, became the first synthetic drug through successful malaria treatment in 1891. Its redox reactive properties are demonstrated in the blue bottle experiment, where it can turn a mixture blue and then colorless. These properties make methylene blue effective in catalyzing phototherapy for superficial infections and tumors. Furthermore, it has the ability to oxidize or reduce different targets, allowing it to rewire the mitochondrial respiratory chain.
Medical Use and Potential Benefits of Methylene Blue
Methylene blue is employed for treating methemoglobinemia, Alzheimer's disease, and cyanide/hydrogen sulfide poisoning. It can enhance memory and prevent certain poisons from reaching cells. However, its effects on the brain's visual motor loop could potentially increase the risk of falls. Methylene blue also acts as an MAOI, offering antidepressant and anti-anxiety effects, but may carry risks of serotonin toxicity, hypertension, and dependence. It is used for various medical purposes, including treating inherited methemoglobinemia, preventing surgical complications, and addressing superficial infections and skin cancer in conjunction with phototherapy.
