The agonistic activity of fluorinated and nonfluorinated fentanyl analogs on µ-opioid receptor was investigated using a cell-based assay system. Based on the activity, fentanyl analogs were ranked as follows: fentanyl > isobutyrylfentanyl ≈ butyrylfentanyl ≈ methoxyacetylfentanyl > acetylfentanyl. However, among the fentanyl analogs fluorinated on the N-phenyl ring, 2-fluoro analogs and 3-fluoro analogs showed the strongest and weakest activities, respectively. These results suggest that the 2-fluorinated isomers of fentanyl analogs are more likely to cause poisoning.
使用基于细胞的检测系统研究了含氟和不含氟的芬太尼类似物在μ-阿片受体上的拮抗活性。根据活性,芬太尼类似物的排名如下:芬太尼 > 异丁酰芬太尼 ≈ 丁酰芬太尼 ≈ 甲氧基乙酰芬太尼 > 乙酰芬太尼。然而,在N-苯环上含氟的芬太尼类似物中,2-氟类似物显示出最强活性,而3-氟类似物显示出最弱活性。这些结果表明,2-氟化的芬太尼类似物更可能导致中毒。
