this disease. Here, we describe a novel class of potent tryptophan hydroxylase inhibitors, characterized by spanning all active binding sites important for catalysis, specifically those of the cosubstrate pterin, the substrate tryptophan as well as directly chelating the catalytic iron ion. The inhibitors were designed to efficiently reduce serotonin in the periphery while not passing the blood–brain
色氨酸羟化酶催化血清素合成的第一步和限速步骤。5-羟色胺是中枢神经系统中的一种关键神经递质,在外周,作为具有多种生理功能的局部激素发挥作用。对转基因小鼠模型的研究表明,外周血清素水平的失调会导致代谢、炎症和纤维化疾病。肿瘤细胞过度产生血清素会导致类癌综合征典型的严重症状,色氨酸羟化酶抑制剂已经在临床上用于患有这种疾病的患者。在这里,我们描述了一类新的强效色氨酸羟化酶抑制剂,其特征在于跨越所有对催化重要的活性结合位点,特别是那些共底物蝶呤,底物色氨酸以及直接螯合催化铁离子。这些抑制剂旨在有效减少外周的血清素,同时不通过血脑屏障,从而保持大脑中的血清素水平。
