Biological Activity
Ki: 0.12 μM (tau)[3].
Leucomethylene blue (100 nM, 48 h) mesylate not only decreases the tau and p-tau expression levels, but also reverses the promoting effects of Aβ25-35 on orexin A and adenosine A1R expression levels[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
