L-苯丙氨酸
(S)-2-Amino-3-phenylpropionic acid

L-Phenylalanine ((S)-2-Amino-3-phenylpropionic acid) 是分离自大肠杆菌的必需氨基酸。L-Phenylalanine 是一种电压依赖性 α2δ 亚基Ca2⁺通道拮抗剂，K_i为 980 nM。L-Phenylalanine 是NMDARs(K_B573 μM) 和非NMDARs的甘氨酸和谷氨酸结合位点的竞争性拮抗剂。L-Phenylalanine 广泛用于食品香料和药品的生产中。

生物活性

L-Phenylalanine ((S)-2-Amino-3-phenylpropionic acid) is an essential amino acid isolated fromEscherichia coli. L-Phenylalanine is aα2δ subunit of voltage-dependent Ca⁺channelsantagonist with aK_iof 980 nM. L-phenylalanine is a competitive antagonist for the glycine- and glutamate-binding sites ofN-methyl-D-aspartate receptors (NMDARs)(K_Bof 573 μM ) andnon-NMDARs, respectively. L-Phenylalanine is widely used in the production of food flavors and pharmaceuticals^[1]^[2]^[3]^[4].

体外研究
(In Vitro)

DAHP synthetase (DS) and chorismate mutase/prephenate dehydratase (CM/PD) are key enzymes in the L-Phenylalanine biosynthesis pathway. DS is sensitive to feedback inhibition by tyrosine, and CM/PD is subject to feedback inhibition by L-Phenylalanine^[1]. L-Phenylalanine attenuates non-NMDA receptor function in cultured neurons with an IC₅₀of 980 μM^[5].

体内研究
(In Vivo)

The effects of L-Phenylalanine on NMDA-activated currents (I_NMDA) are studied in cultured hippocampal neurons from newborn rats using the patch-clamp technique. L-Phenylalanine specifically and reversibly attenuates I_NMDAin a concentration-dependent manner (IC₅₀of 1.71 mM). L-Phenylalanine inhibits specifically NMDAR current in hippocampal neurons by competing for the glycine-binding site^[3].
