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
MUC-1C
In vitro
GO-203 inhibits MUC1-C homodimerization which blocks its oncogenic function. Treatment of MUC1-overexpressing SKCO-1 and Colo-205 colon cancer cells with this compound is associated with downregulation of the TP53-inducible glycolysis and apoptosis regulator (TIGAR) protein. This chemical regulates AKT-S6K1-elF4A signaling in colorectal cancer cells. Targeting MUC1-C with it inhibits p-AKT in colorectal cancer cells. This treatment also results in increases in reactive oxygen species (ROS) and loss of mitochondrial transmembrane potential.
In vivo
GO-203 is effective in inhibiting growth and survival of MUC1-positive colorectal cancer cells in mouse xenograft models. It is also effective in xenografts models of breast, prostate, lung and certain hematologic malignancy.
