Biological Activity
| Description | Lomeguatrib (PaTrin-2) is a potent inhibitor of O6-alkylguanine-DNA-alkyltransferase with IC50 of 5 nM. | ||
|---|---|---|---|
| Targets |
|
||
| In vitro | Lomeguatrib inactivates O6-alkylguanine-DNA-alkyltransferase (ATase) with a IC50 10-fold lower than O6-Benzylguanine. Lomeguatrib inhibits the activity of ATase in Raji cells with IC50 of 10 nM. [1] Lomeguatrib effectively inactivates MGMT in MCF-7 cells with IC50 of ~6nM ). |
||
| In vivo | The Lomeguatrib combination results in considerably less toxicity (0/9 vs. 2/9 deaths; 6.84% weight loss vs. 9.48%). Lomeguatrib alone has no significant effect on tumour growth. [3] |
