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
