| Bioactivity | Leucomethylene blue (TRx0237) mesylate, an orally active second-generation tau protein aggregation inhibitor (Ki of 0.12 μM), could be used for the study of Alzheimer's Disease. Leucomethylene blue mesylate is a common reduced form of Methylene Blue, Methylene Blue is a member of the thiazine class of dyes[1][2][3]. |
| Target | Ki: 0.12 μM (tau). |
| Invitro | Leucomethylene blue (100 nM, 48 h) mesylate not only decreases the tau and p-tau expression levels, but also reversed the promoting effects of Aβ25-35 on orexin A and adenosine A1R expression levels[2]. Western Blot Analysis[2] Cell Line: |
