L-Phenylalanine ((S)-2-Amino-3-phenylpropionic acid) is an essential amino acid isolated from Escherichia coli. L-Phenylalanine is a α2δ subunit of voltage-dependent Ca channels antagonist with a Ki of 980 nM. L-phenylalanine is a competitive antagonist for the glycine- and glutamate-binding sites of N-methyl-D-aspartate receptors (NMDARs) (KB of 573 μM ) and non-NMDARs, respectively. L-Phenylalanine is widely used in the production of food flavors and pharmaceuticals.

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.L-Phenylalanine attenuates non-NMDA receptor function in cultured neurons with an IC50 of 980 μM.Medlife has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
The effects of L-Phenylalanine on NMDA-activated currents (INMDA) are studied in cultured hippocampal neurons from newborn rats using the patch-clamp technique. L-Phenylalanine specifically and reversibly attenuates INMDA in a concentration-dependent manner (IC50 of 1.71 mM). L-Phenylalanine inhibits specifically NMDAR current in hippocampal neurons by competing for the glycine-binding site.Medlife has not independently confirmed the accuracy of these methods.
