Description
IC50 & Target
Ki: 0.12 μM (tau)[3].
In Vitro
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.
-
Cell Line:Human SH-SY5Y cell line.
-
Concentration:100 nM.
-
Incubation Time:48 h.
-
Result:Aβ25-35 and TRx 0237 co-treatment significantly reversed the promoting effects of Aβ25-35 on tau, p-tau, orexin A and adenosine A1R expression.
