Camellia sinensis. It has received much attention because of its pleiotropic physiological and pharmacological activities leading to health benefits in humans, especially. We describe here a new, easy, efficient, and environmentally friendly chemical synthesis of l-theanine and l-γ-N-propyl-Gln and their corresponding d-isomers. l-Theanine, and its derivatives obtained so far, exhibited partial coagonistic
l-茶氨酸(或l - γ - N-乙基-谷氨酰胺)是山茶中发现的主要氨基酸。由于其多效性的生理和药理活性特别是对人类健康有益,因此受到了广泛的关注。在这里,我们描述了一个新的,方便,高效和环境友好的化学合成升-theanine和升-γ- ñ丙基谷氨酰胺和它们对应的d异构体。到目前为止,l-茶氨酸及其衍生物在N-甲基-d处表现出部分拮抗作用。-天冬氨酸(NMDA)受体,对培养的海马神经元没有其他谷氨酸受体的激动作用。该活性保留在非洲爪蟾卵母细胞中表达的NMDA受体上。另外,含有1-甲基茶氨酸的NMDA受体的GluN2A和GluN2B均被1-茶氨酸同样地调节。如在培养的海马神经元上所测量的,从1-茶氨酸到d-茶氨酸的立体化学变化以及乙基取代1-和d-茶氨酸的γ- N位置上的丙基部分显着增强了生物学功效。升因此,-茶氨酸结构代表了开发新型NMDA受体调节剂的有趣骨架。
