| 生化机理 | 犬尿氨酸(KynA)是 N-甲基-d-天冬氨酸(NMDA)、α-氨基-3-羟基-5-甲基-4-异恶唑丙酸(AMPA)和凯因酸受体的非选择性拮抗剂。它能阻断凯尼克酸的神经毒性。犬尿氨酸还能阻断烟碱乙酰胆碱受体。它是色氨酸分解途径的副产品。犬尿氨酸是一种神经调节剂,可控制谷氨酸、多巴胺、乙酰胆碱和α-氨基丁酸(GABA)的水平。KynA 控制神经内分泌功能,KynA 水平的改变是抑郁症、精神分裂症、阿尔茨海默氏症和亨廷顿氏症的潜在标志。大脑中正常水平的 KynA 对认知功能至关重要。它是离子型、甘氨酸 β 和 α7 尼古丁受体的内源性拮抗剂。在体内具有神经保护作用。 | |||||||||

| 产品介绍 |
Kynurenic acid is a metabolite of tryptophan in mammals via the kynurenine pathway. Studies have observed that Kynurenic acid acts as a ligand to the GPR35 G protein-coupled receptor. The binding of Kynurenic acid to GPR35 has been noted to affect calcium mobilization and inositol phosphatase synthesis and may indicate potential signaling functions by Kynurenic acid via the GPR35 receptor. Additionally reported to be a broad spectrum, excitatory amino acid (EAA) antagonist. Other studies have reported that Kynurenic acid acts as an antagonist to mammalian ionotropic glutamate receptors especially NMDA (N-methyl-D-aspartate receptors).Kynurenic acid is an inhibitor of AChR α7, GluR and GlyR.
Kynurenic acid has been used as a constituent in dissection saline solution for embryonic cerebral cortical cells[7] and human primary astrocytes. It has also been used as a medium supplement for murine intestinal epithelial cell line, MODE-K and induced pluripotent stem cell (iPSC)-derived neurons cells.
