| Description | Pitolisant is a potent and selective nonimidazole inverse agonist that targets the recombinant human histamine H3 receptor, with a Ki of 0.16 nM. |
| Targets&IC50 | H3 receptor:1.5 nM (EC50), H3 receptor:0.16 nM (Ki) |
| In vitro | When stimulating [35S]-thiophosphate-labeled GTPγS binding to recombinant human H3 receptors, Pitolisant (BF2.649) acts as a competitive antagonist with a Ki value of 0.16 nM. As a reverse agonist, its EC50 value is 1.5 nM, with intrinsic activity about 50% higher than that of ciproxifan[1]. |
| In vivo | Pitolisant (BF2.649) dose-dependently enhances histamine levels in the mouse brain, with an ED50 value of 1.6 mg/kg p.o. This effect persists after repeated administration for 17 days[1]. |
