Product Introduction

Bioactivity
Description
Leucomethylene blue mesylate (TRx0237 mesylate) is a second-generation tau protein aggregation inhibitor for the treatment of Alzheimer's disease (AD) and frontotemporal dementia.
Targets&IC50
Tau:0.12 μM (Ki)
In vitro
Leucomethylene blue is a second-generation tau protein aggregation inhibitor for the treatment of Alzheimer's disease (AD) and frontotemporal dementia. It is a purified forms of Methylene Blue, an old drug that predates the FDA and is being widely used in Africa for the treatment for malaria as well as for methemoglobinemia and other conditions[2]. An in vitro study showed the ability of Leucomethylene blue in disrupting PHFs(paired helical filaments) isolated from Alzheimer's Disease brain tissues at the concentration at 0.16 μM[1].
In vivo
Leucomethylene blue dose-dependently rescues the learning impairment and restores behavioral flexibility in a spatial problem-solving water-maze task in L1 (minimum effective dose: 9 mg MT/kg for TRx0237) and correctes motor learning in L66 (effective doses: 4 mg MT/kg). It reduces the number of tau-reactive neurons, particularly in the hippocampus and entorhinal cortex in L1 and in a more widespread manner in L66[1].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
