Description

TRx 0237 mesylate (LMTX, Hydromethylthionine) is a second-generation tau protein aggregation inhibitor for the treatment of Alzheimer's disease (AD) and frontotemporal dementia.

Targets

tau protein aggregation ^[1]

In vitro
In vitro	TRx 0237 (LMTX™) 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 TRx 0237 in disrupting PHFs(paired helical filaments) isolated from Alzheimer's Disease brain tissues at the concentration at 0.16 μM^[1].

In Vivo
In vivo	TRx 0237 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].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
