Receptor Profile
Der 5-HT1A-Rezeptor ist ein Gi/Go-gekoppelter Serotoninrezeptor, der als Autorezeptor auf serotonergen Neuronen und als Heterorezeptor in verschiedenen Hirnregionen vorkommt. Er moduliert Angst, Stimmung und Kognition.
Der Dopamintransporter (DAT) ist ein Natrium-abhängiger Monoamintransporter, der Dopamin aus dem synaptischen Spalt entfernt. Er ist ein zentrales Ziel von Stimulants und spielt eine Schlüsselrolle im Belohnungssystem.
Der α1-adrenerge Rezeptor ist ein Gq/11-gekoppelter GPCR, der Vasokonstriktion, Mydriasis und glatte Muskelkontraktion vermittelt. Er spielt eine zentrale Rolle bei der sympathischen Kreislaufregulation.
