Biological Activity

Description GSK2981278 is a highly potent and selective inverse agonist for RORγ.
RORγ [1]
In vitro

GSK2981278 has no significant effect on RORα-dependent activation. GSK2981278 significantly inhibits production of the Th17 signature (IL-17A, IL-17F, IL-22 and IL-23) in multiple in vitro and human tissue-based assays[1].

In vivo

GSK2981278 attenuates inflammation in a mouse model of psoriasis. Topical treatment with GSK2981278 will significantly limit Th17-type cytokine expression and should therefore lead to improved clinical outcomes for patients[1].

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.
