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	COX LOX
In vivo	Phenidone has provided neuroprotection in various experimental paradigms of neurodegeneration including kainate-induced excitotoxicity, ischemia, microglia-mediated neurotoxicity, and autoimmune encephalomyelitis. However, the neuroprotective effect of the compound appeared to be associated not only with inhibition of COX and LOX activities but also with its direct antioxidant property. Microglia-related neurotoxicity is believed to be partially mediated by oxidative/nitrosative stress.
