tryptophan, two N (1)-fluoroalkylated tryptophan derivatives, are described here. In vitro enzymatic assays with these two new potential substrates of hIDO show that 1-FETrp is a good and specific substrate of hIDO. Therefore, its radioactive isotopomer, 1-[(18)F]FETrp, should be a molecule of choice to visualize tumoral and inflammatory tissues and/or to validate new potential inhibitors.
吲哚胺2,3-二加氧酶(hIDO)是一种酶,可通过犬尿氨酸途径催化1-色氨酸吲哚环的氧化裂解,从而在炎症和肿瘤组织中发挥免疫抑制特性。1-(2-氟乙基)-色氨酸(1-FETrp)和1-((1-(2-氟乙基)-1H-1,2,3-三唑-4-基)甲基)-色氨酸的合成,两个在此描述了N(1)-氟代烷基色氨酸衍生物。用hIDO的这两种新的潜在底物进行的体外酶分析表明1-FETrp是hIDO的良好而特异性的底物。因此,其放射性同位素异构体1-[((18)F] FETrp)应该成为可视化肿瘤和炎性组织和/或验证新的潜在抑制剂的分子选择。
