  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。

  of hexafluoroisopropyl carbamate-based irreversible inhibitors of MGLL, culminating in a highly potent, selective, and orally available, CNS-penetrant MGLL inhibitor, 28 (ABX-1431). Activity-based protein profiling experiments verify the exquisite selectivity of 28 for MGLL versus other members of the serine hydrolase class. In vivo, 28 inhibits MGLL activity in rodent brain (ED50 = 0.5-1.4 mg/kg)

  丝氨酸水解酶单酰基甘油脂酶（MGLL）将内源性大麻素受体激动剂2-花生四烯酰基甘油（2-AG）和其他单酰基甘油转化为脂肪酸和甘油。MGLL的遗传或药理失活导致中枢神经系统2-AG升高，花生四烯酸和类二十烷酸相应减少，从而产生抗伤害性，抗焦虑和抗神经炎作用，而没有引起直接大麻素受体激动剂的全部精神活性作用。在这里，我们报告了基于六氟异丙基氨基甲酸酯的MGLL不可逆抑制剂的优化，最终形成了一种高效，选择性和口服的CNS渗透性MGLL抑制剂28（ABX-1431）。基于活性的蛋白质谱分析实验证明了MGLL与丝氨酸水解酶类别的其他成员相比具有28的出色选择性。在体内，28在鼠福尔马林疼痛模型中抑制了啮齿动物大脑中的MGLL活性（ED50 = 0.5-1.4 mg / kg），增加了大脑2-AG的浓度，并抑制了疼痛行为。ABX-1431（28）目前正在人类临床试验中进行评估。
