| Description | SKLB-197 is a potent and highly selective inhibitor of ataxia telangiectasia and Rad3-related kinase (ATR) with an IC50 value of 0.013 μM and minimal activity against more than 402 other kinases. SKLB-197 shows strong antitumor efficacy in ATM-deficient tumors both in vitro and in vivo, while also exhibiting favorable pharmacokinetic properties for oncology research. |
| Targets&IC50 | ATR:> 10 μM |
| In vitro | In enzymatic assays, SKLB-197 inhibited ATR kinase (IC50 = 13 nM) with selectivity over ATM and DNA-PK. In cellular models, it inhibited UV- or Gemcitabine-induced CHK1 phosphorylation and demonstrated antiproliferative activity against cancer cells with high replication stress, leading to cell cycle arrest and apoptosis [1]. |

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.
