| In Vivo | 4-Ethynyl-L-phenylalanine hydrochloride (30 mg/kg; i.p.) decreases in 5-HT and 5-HIAA levels in the rat midbrain but not in tissue[1]. 4-Ethynyl-L-phenylalanine hydrochloride is not inhibiting the aromatic amino acid decarboxylase[1]. 4-Ethynyl-L-phenylalanine hydrochloride has a low affinity for various recombinant 5-HT receptors[1]. Animal Model: Male Sprague-Dawley rats (200 g)[1] Dosage: 30 mg/kg Administration: Intraperitoneal injection Result: Decreased in 5-HT and 5-HIAA levels in the rat midbrain. |
