Background

Potent sepiapterin reductase (SPR) inhibitor (IC50 = 53 - 74 nM for human SPR). Inhibits BH4 synthesis pathway and attenuates proliferation in naive CD4+ T cells. Suppresses proliferation of human effector CD4+ T cells following stimulation. Reduces SPR activity in mouse primary cultures of sensory neurons (IC50 = 450 nM). Ameliorates colitis, suppressing the intestinal infiltration of T cells and other immune cells in vivo. Also reduces immune-cell infiltration into mouse lungs. Reduces neuropathic and inflammatory pain in mouse models.

In vivo Formulation Calculator (Clear solution)

Step 1: Enter information below (Recommended: An additional animal making an allowance for loss during the experiment)

mg/kg g μL

Step 2: Enter the in vivo formulation (This is only the calculator, not formulation. Please contact us first if there is no in vivo formulation at the solubility Section.)

Calculation results:

Working concentration: mg/ml;

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.
3. All of the above co-solvents are available for purchase on the GlpBio website.
