Description of GS-143

GS-143 is an inhibitor of IκBα ubiquitylation.[1] It inhibits ubiquitylation of phosphorylated IκBα mediated by the SCFβTrCP1 E3 ubiquitin ligase complex in vitro (IC50 = 5.2 μM) and reduces TNF-α-induced degradation of phosphorylated IκBα, but not β-catenin, another SCFβTrCP1 substrate, in HeLa S3 cells. GS-143 inhibits LPS-induced expression of TNF-α, IL-6, IL-12, ICAM-1, and NF-κB in THP-1 cells in a concentration-dependent manner. Intranasal administration of GS-143 (32 μg/animal) reduces the number of eosinophils, lymphocytes, and total cells in bronchoalveolar lavage fluid (BALF) in an ovalbumin-sensitized mouse model of allergic asthma.[2]

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.
