WB403
Based on 1 Customer Validation
WB403 is an orally active TGR5 activator with an EC50 of 5.5 μM against human TGR5. WB403 activates TGR5 to stimulate downstream signaling pathways, promote GLP-1 secretion, improve glucose tolerance in mice with type 2 diabetes, and reduce levels of fasting blood glucose, postprandial blood glucose and HbA1c. WB403 increases pancreatic β-cell mass and restores the distribution of α-cells and β-cells in islets. WB403 is applicable to the research of type 2 diabetes.

Biological Activity
WB403 (1-20 μM; 16 h) dose-dependently activates human TGR5 in transiently transfected 293T cells with an EC50 of 5.5 μM, as measured by a CRE-luciferase reporter assay[1].
WB403 (10 μM; 30 min) significantly stimulates active GLP-1 secretion from human NCI-H716 enteroendocrine cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:293T cells (transiently transfected with pTGR5)
-
Concentration:0, 1, 5, 10, 20, 50 μM
-
Incubation Time:30 min
-
Result:Dose-dependently stimulated TGR5-mediated cAMP accumulation, with statistically significant increases observed at all tested concentrations relative to the DMSO (+TGR5) control.
Showed no stimulation in control 293T cells transfected with an empty plasmid.
WB403 (50-100 mg/kg; p.o.; daily; for 4 consecutive weeks) significantly reduces fasting and postprandial blood glucose levels, decreases HbA1c, increases insulin levels, restores the normal distribution of islet cells, and expands islet area in spontaneous type 2 diabetic db/db mice[1].
WB403 (50-100 mg/kg; p.o.; single administration) significantly improves glucose tolerance and increases serum GLP-1 levels in normal ICR mice[1].

-
Animal Model:ICR mice (male, 5 weeks old, high-fat diet + streptozotocin-induced type 2 diabetes)[1]
-
Dosage:50 mg/kg; 100 mg/kg
-
Administration:p.o.; daily; 8 weeks
-
Result:Significantly decreased fasting blood glucose and postprandial blood glucose starting from the first week of intervention, with effects sustained throughout the 8-week treatment period.
Significantly reduced serum HbA1c levels compared to vehicle controls.
Restored pancreatic islet area to near-normal levels, reversing β-cell loss induced by streptozotocin.
Decreased water intake, indicating improved hyperglycemia, while food intake and body weight did not vary significantly compared to vehicle controls.
-
Animal Model:db/db (C57BL BKS cg-M+/+ lepr-/-) mice (male, 8 weeks old, spontaneous type 2 diabetes)[1]
-
Dosage:50 mg/kg; 100 mg/kg
-
Administration:p.o.; daily; 4 weeks
-
Result:Significantly decreased fasting blood glucose and postprandial blood glucose after 1 week of treatment, with effects sustained throughout the 4-week period.
Significantly reduced serum HbA1c levels and increased serum insulin levels compared to vehicle controls.
Decreased water intake, indicating improved hyperglycemia, while food intake and body weight did not vary significantly compared to vehicle controls.
Reduced α-cell infiltration in the islet core, restoring the normal distribution pattern of α-cells (peripheral) and β-cells (core), and increased pancreatic islet area compared to vehicle controls.
-
Animal Model:ICR mice (male, non-diabetic)[1]
-
Dosage:50 mg/kg; 100 mg/kg
-
Administration:p.o.; single dose; 30 minutes before glucose challenge
-
Result:Significantly improved glucose tolerance in normal mice, as shown by reduced blood glucose levels during oral glucose tolerance test and decreased area under the curve (AUC) compared to vehicle controls.
Significantly increased serum GLP-1 concentrations compared to vehicle controls.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
