KBP-089
Based on 1 Customer Validation
KBP-089 is a dual Amylin and Calcitonin Receptor agonist. KBP-089 reduces body weight, decreases adipose tissue mass and improves glucose tolerance in obese rats. KBP-089 also eliminates lipid accumulation in the liver and muscle, and ameliorates glycemic homeostasis and insulin sensitivity. KBP-089 is applicable to the research of diseases such as obesity and type 2 diabetes.

Biological Activity
KBP-089 (3 h) potently activates human CTR and AMY3-R in heterologous cell lines with its pEC50 values ranging from 8.7 to 9.9, and can induce sustained receptor activation for up to 72 hours[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
KBP-089 (0.625-40 μg/kg; s.c.; 6 weeks) reduces body weight and improves glucose tolerance in high-fat diet-fed rats following 4-fold dose escalation administration[1].
KBP-089 (0.625-40 μg/kg; s.c.; single dose) dose-dependently suppresses caloric intake in overnight-fasted high-fat diet-fed rats within 48 h[1].
KBP-089 (5-20 μg/kg; s.c.; 8 weeks total) reduces blood glucose levels, improves glucose tolerance and enhances insulin action in diabetic obese rats[2].
KBP-089 (2.5 µg/kg; s.c.; 7 days) reduces total caloric intake in rats fed a normal diet and shifts their food preference from chocolate to standard chow[2].

-
Administration:s.c.; daily; 8 weeks total
-
Result:Reduced fasting blood glucose over 7 weeks.
Reduced HbA1c at study end; Lowered oral glucose tolerance test tAUC.

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 (0.71 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 (0.71 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
