体外研究(In Vitro)
p-Ethynylphenylalanine hydrochloride selectively and reversibly inhibits the biosynthesis of serotonin.p-Ethynylphenylalanine hydrochloride has a low affinity for various recombinant 5-HT receptors (5-HT1, 5-HT2, 5-HT4, 5-HT5, 5-HT6, and 5-HT7). has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
p-Ethynylphenylalanine hydrochloride (30 mg/kg; i.p.) decreases in 5-HT and 5-HIAA levels in the rat midbrain but not in tissue.
p-Ethynylphenylalanine hydrochloride does not inhibit the aromatic amino acid decarboxylase. has not independently confirmed the accuracy of these methods. They are for reference only.
