Biological Activity

Description WS3 is a β cell proliferation inducer via modulation of Erb3 binding protein-1 (EBP1) and the IκB kinase pathway.
Targets
EBP1 [1] IκB kinase [1]
In vitro
In vitro WS3 induces proliferation of the mouse β cell line R7T1 with EC50 of 0.074 μM. [1] WS3 reversibly induces proliferation of primary fetal and adult human retinal pigment epithelial (RPE) cells. [2]
Cell Research Cell lines R7T1 cells
Concentrations ~10 μM
Incubation Time 4 days
Method R7T1 cells are growth-arrested by removal of doxycycline for 2 days and plated into 384-well plates at a density of 3,000 cells/well in growth medium. Β cell proliferation is assessed using CellTiter Glo after 4 days. Fold increase in cell number is calculated by normalizing compound-treated wells to the median of DMSO-treated wells.

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.
