laboratories produce analogues of fentanyl, known as fentalogues to circumvent legislation regarding its production. Three pyridyl fentalogues were synthesized and then hyperpolarized by signal amplification by reversible exchange (SABRE) to appraise the forensic potential of the technique. A maximum enhancement of ‐168‐fold at 1.4 T was recorded for the ortho pyridyl 1H nuclei. Studies of the activation parameters
芬太尼,也被称为“困境”,是一种合成的阿片类药物,效力比吗啡高50-100倍。秘密实验室生产芬太尼的类似物,被称为fentalogues,以绕开有关其生产的立法。合成了三个吡啶基苯甲酸酯类化合物,然后通过可逆交换(SABRE)进行信号放大来超极化,以评估该技术的法医潜力。对于正吡啶基1 H核,在1.4 T时记录到最大168倍的增强。对于三个fentalogues激活参数的研究表明,配位体损失的比率反向氢化物和氢化物损失的配合物[Ir(IMES)(L)3(H)2 ] +(IMES = 1,3-双(2,4,6-三甲基苯基)咪唑-2-亚基)的范围为0.52至1.83。在地球磁场下进行SABRE之后,具有最接近于单位的比率的fentalogue产生了最大的增强作用。可以从主要由海洛因组成的基质(97:3海洛因:fentalogue)中选择性地使吡啶基苯妥英钠超极化,以验证SABER作为法医工具的用途。
