Sample solution is provided at 25 µL, 10mM.



Description of A 1899

Potent K2P3.1 (TASK-1) and K2P9.1 (TASK-3) channel blocker (IC50 values are 7 nM and 70 nM for human TASK-1 and TASK-3 expressed in CHO cells, respectively). Displays >12.5-fold selectivity for TASK-1 and TASK-3 over other K+ channels (IC50 = 0.9 μM for K2P18.1/TRESK and >2 μM for all other channels tested). Binds within open channel pore.

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 saline, 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.
