KU-60019
KU-60019 is a selective inhibitor of the Ataxia telangiectasia (A-T) mutated (ATM) protein with an IC50 value of 6.3 nM. In literature report, KU-60019 radiosensitizes h-TERT-immortalized normal fibroblasts but not A-T fibroblasts, suggesting it is a specific ATM kinase radiosensitizer [1].
KU-60019 can reduce radiation-induced AKT phosphorylation in human glioma cell lines that are p53 wild type (U87) and p53 mutant (U1242). However, the suppression of AKT does not enhance radiosensitization of KU-60019 [1].
KU-60019 has been reported to inhibit cell migration and invasion in human glioma cells U87 and U1242 in a dose-dependent manner. Besides, KU-60019, to some extent, has also been shown to suppress the growth of U1242 cells [1].

| Shipping Condition | Small Molecules with Blue Ice, Modified Nucleotides with Dry Ice. |
| General tips | We do not recommend long-term storage for the solution, please use it up soon. |
| Cell experiment [1]: | |
| Cell lines | U87 and U1242 cells |
| Preparation method | The solubility of this compound in DMSO is > 27.4 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 μM; 1, 3 and 5 days |
| Applications | In U87 cells, KU-60019 at 3 μM significantly inhibited cell migration and invasion by > 70% and ~ 60%, respectively. Similarly, KU-60019 also substantially inhibited migration and invasion of human glioma U1242 cells by > 50% and ~ 60%, respectively. |
| Animal experiment [2]: | |
| Animal models | Athymic female mice implanted with U1242/luc-GFP cells |
| Dosage form | KU-60019 (10 μM) delivered intratumorally at a rate of 0.5 μL/h by osmotic pump, for 14 days |
| Applications | In athymic female mice implanted with U1242/luc-GFP cells, the combination of KU-60019 and radiation significantly inhibited tumor growth than radiation alone, which suggested that KU-60019 might radiosensitize U1242 gliomas. |
| Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
