6bK TFA
Based on 2 publication(s) in Google Scholar
6bK TFA is a selective insulin-degrading enzyme (IDE) inhibitor with an IC50 of 50 nM. 6bK TFA binds to the distal pocket of IDE, thereby blocking substrate binding, peptide unfolding and cleavage processes, and reducing the degradation of insulin, glucagon and amylin. 6bK TFA improves oral glucose tolerance but impairs intraperitoneal glucose tolerance. 6bK TFA can be used in research related to type 2 diabetes.

Biological Activity
|
IDE 50 nM (IC50) |
6bK TFA potently inhibits IDE activity with an IC50 of 50 nM[2].
6bK (1 h) TFA exhibits a high plasma protein binding rate, as well as favorable 1-hour stability in mouse plasma and microsomes[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Acute inhibition of insulin-degrading enzyme by 6bK (40-90 mg/kg) TFA improves oral glucose tolerance in lean and DIO mice, delays gastric emptying via the amylin signaling pathway, impairs intraperitoneal glucose tolerance via the glucagon signaling pathway, and enhances insulin-mediated hypoglycemic responses, all of which depend on IDE activity[2].
6bK (80 mg/kg; i.p.; single administration) TFA exhibits a potentiated hypoglycemic response to insulin injection in mice[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:C57BL/6J mice (male; lean: 14-16 weeks old; diet-induced obese: 24-26 weeks old, >20 weeks on high-fat diet)[2]
-
Dosage:40-90 mg/kg
-
Administration:single injection
-
Result:Increased relative blood glucose profile areas during IPGTT.
Reduced relative blood glucose during the OGTT.
Showed stronger hypoglycaemic responses to insulin, stronger hyperglycaemic responses to amylin and glucagon.

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
Solubility: ≥ 2.5 mg/mL (2.87 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (2.87 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
