routes and all the analogs were found to be safer than fentanyl. Observational assessment on spontaneous activities of the central nervous system, peripheral nervous system, and autonomic nervous system revealed that all the analogs were similar to fentanyl. Further, the neurotoxic effects of all the analogs were reversed by naloxone hydrochloride (opioid antagonist), confirming that their effects were mediated
芬太尼[ N-(1-苯乙基-4-哌啶基)丙酰苯胺]是一种流行的麻醉镇痛剂,在世界范围内都在临床上使用。然而,由于剂量过量和狭窄的治疗指数,芬太尼及其几种类似物已在人类中引起滥用和死亡。本研究报告了芬太尼及其四个类似物,即N-(1-丙基-4-哌啶基)丙酰苯胺(1),N-(1-(2-苯氧基乙基)-4-哌啶基)的合成和比较生物功效。丙酰苯胺(2),N-(1-(3-(苯氧丙基)-4-哌啶基)丙酰苯胺(3)和N-(1-(2-氰基乙基)-4-哌啶基)丙酰苯胺(4),其中芬太尼的苯乙基链被不同的官能团取代,即烷基,醚基和腈基。通过三种不同的途径确定化合物的中值致死剂量(LD 50),发现所有类似物比芬太尼更安全。通过对中枢神经系统,周围神经系统和自主神经系统自发活动的观察评估,发现所有类似物均与芬太尼相似。此外,所有类似物的神经毒性作用均被盐酸纳洛酮(阿片类药物拮抗剂)逆转,证实它们的作用是通过阿片样物
