alpha-amino acid derivatives were prepared as glycine transport inhibitors and their ability to block the uptake of [(14)C]-glycine in COS7 cells transfected with human glycine transporter-2 (hGlyT-2) was evaluated. An array of substituents at the chiral center was studied and overall, L-phenylalanine was identified as the preferred amino acid residue. Compounds prepared from l-amino acids were more
制备了多种α-氨基酸衍生物作为甘氨酸转运抑制剂,并评估了它们在人甘氨酸转运蛋白2(hGlyT-2)转染的COS7细胞中阻断[(14)C]-甘氨酸摄取的能力。研究了手性中心的一系列取代基,总的来说,L-苯丙氨酸被确定为优选的氨基酸残基。与衍生自相应的d-氨基酸的类似物相比,由l-氨基酸制备的化合物是更有效的GlyT-2抑制剂。引入非手性氨基酸(例如甘氨酸)或在α位置引入双链取代,会导致GlyT-2抑制特性显着降低。
