| Description | Antalarmin is a selective and potent corticotropin-releasing factor receptor 1 (CRHR1) antagonist that crosses the blood-brain barrier and blocks CRF activation and carrageenan-induced subcutaneous inflammation in rats. |
| Targets&IC50 | CRHR1:2.7 nM (Ki) |
| In vitro | Antalarmin (100 nM; 48 hours) treatment was able to block CRF-induced increases in PKAIIβ levels in hippocampal neurons derived from Tg2576 mice[2]. |
| In vivo | In the chronic mild stress model using BALB/cByJIco male mice, intraperitoneal administration of Antalarmin (10 mg/kg; once daily for 4 weeks) was able to significantly improve the physical state of the mice[1]. |
