Methylene-blue
An organic cation that is phenothiazin-5-ium substituted by dimethylamino groups at positions 3 and 7. The chloride salt is the histological dye 'methylene blue'. Solutions in water or alcohol have a deep blue color. Methylene blue is used as a bacteriologic stain and as an indicator (E-numbers for permitted antioxidant food additives are from E 300 to E 324). It inhibits guanylate cyclase, and has been used to treat cyanide poisoning and to lower levels of methemoglobin. Methylthioninium chloride (INN, or methylene blue, proposed trade name Rember) is an investigational drug being developed by the University of Aberdeen and TauRx Therapeutics that has been shown in early clinical trials to be an inhibitor of Tau protein aggregation. The drug is of potential interest for the treatment of patients with Alzheimer's disease
