Description: Biological stain; also neuroprotective and antimalarial
Chemical Name: 3,7-bis(Dimethylamino)phenazathionium chloride
Biological Activity for Methylene Blue
Methylene Blue is a biological stain and redox indicator. Methylene blue inhibits monoamine oxidase A, tau filament formation and nitric oxide synthase (IC50 values = 0.07 μM, 1.9 μM and 5.3 μM, respectively), and inhibits guanylate cyclase. Methylene Blue delays senescence and stimulates proliferation of fibroblasts and skin cells. In vitro, Methylene Blue promotes wound healing, upregulates elastin expression and production, increases synthesis of heme, is neuroprotective (EC50 = 0.18 nM) and rescues the loss of dopaminergic neurons induced by Rotenone (Cat. No. 3616). Also antimalarial.
