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.

Mechanism of Action

Targets/IC₅₀/Ki	Aβ
In vitro	EUK 134 shows potent catalase and SOD activities, and protects human fibroblasts against cytotoxicity by glucose and glucose oxidase. This compound (20 μM) prevents Aβ-induced microglial proliferation in vitro. In SK-N-MC cells, it protects neuronal cells against H(2)O(2) toxicity by attenuating oxidative stress through inhibition of MAPK pathway, and also results in decreased expression of pro-apoptotic genes p53 and Bax as well as enhanced expression of anti-apoptotic Bcl-2 gene. It significantly inhibits amyloid formation at two molar ratios of 1:1 and 5:1 (drugs to protein).
In vivo	EUK 134 (2.5 mg/kg), in a middle cerebral artery occlusion model, significantly reduces brain infarct size, and apparently prevents further infarct growth. This compound prevents oxidative stress and attenuates rat brain damage induced by systemic administration of systemic kainic acid (KA).
