A series of four phenothiazine dyes, including methylene blue (MB), were previously tested for their ability to photoinactivate viruses in red cell suspensions. One of the dyes, 1,9-dimethyl-3-dimethylamino-7-dimethylaminophenothiazine (1,9-dimethylmethylene blue), exhibited good intracellular and extracellular virucidal activity for several RNA

A simple and rapid isocratic high-performance liquid chromatographic method for the analysis of methylene violet, a neutral phenothiazine dye, in the presence of DNA has been developed. These chromatographic conditions are also applicable to its N-demethylated, bromo and iodo analogs.
