😃Good
Catalog No. T212527
KB-15 is a STAT3 inhibitor exhibiting significant antiproliferative activity against AGS gastric cancer cells (IC50 = 0.29 μM) and BGC-823 gastric cancer cells (IC50 = 0.65 μM). It exerts its antitumor effects by inhibiting STAT3 phosphorylation, downregulating HO-1 expression, and promoting intracellular reactive oxygen species (ROS) accumulation. Additionally, KB-15 induces G0/G1 phase cell cycle arrest and apoptosis while hindering colony formation and migration in gastric cancer cells. In the BGC-823 subcutaneous xenograft model, KB-15 demonstrates excellent antitumor efficacy.

| Description | KB-15 is a STAT3 inhibitor exhibiting significant antiproliferative activity against AGS gastric cancer cells (IC50 = 0.29 μM) and BGC-823 gastric cancer cells (IC50 = 0.65 μM). It exerts its antitumor effects by inhibiting STAT3 phosphorylation, downregulating HO-1 expression, and promoting intracellular reactive oxygen species (ROS) accumulation. Additionally, KB-15 induces G0/G1 phase cell cycle arrest and apoptosis while hindering colony formation and migration in gastric cancer cells. In the BGC-823 subcutaneous xenograft model, KB-15 demonstrates excellent antitumor efficacy. |
| In vitro | KB-15 exhibits potent antiproliferative effects on AGS gastric cancer cells (IC50 = 0.29 μM) and BGC-823 gastric cancer cells (IC50 = 0.65 μM) over 72 hours. It demonstrates significant colony formation inhibitory activity on both AGS and BGC-823 cells at concentrations of 0.25-2 μM over 14 days. Additionally, KB-15 strongly induces ROS in BGC-823 cells at 0.5-2 μM within 24 hours. It effectively causes G0/G1 phase cell cycle arrest and apoptosis in AGS and BGC-823 cells at concentrations between 0.25-2 μM over 24-36 hours. Furthermore, KB-15 inhibits STAT3 activation in a concentration-dependent manner and downregulates HO-1 expression in BGC-823 cells at 0.5-2 μM within 24 hours. |
| In vivo | The compound KB-15 (2.5 mg/kg, administered intraperitoneally, daily for 14 consecutive days) has demonstrated significant antitumor activity in a subcutaneous xenograft model using BGC-823 cells. |
| Storage | Powder: -20°C for 3 years | In solvent: -80°C for 1 year | Shipping with blue ice/Shipping at ambient temperature. |
Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Stock Solution Preparation:
Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation:
1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
