Abstract

An enkephalin analogue coupled to 'aminofentanyl' has been synthesized and tested for biological activities at the mu and delta opioid receptors. Aminofentanyl which represents a structural derivative of fentanyl has been synthesized by acylation of 1-(2-phenethyl)-4-(N-anilino)piperidine with phthaloyl protected beta-alaninyl chloride in the presence of DIPEA, followed by deprotection with hydrazine hydrate. Aminofentanyl has also been successfully acylated with ethyl isocyanate, various acid anhydrides, to further investigate structure-activity relationships of these new fentanyl derivatives. Among the new derivatives compound 7 which carries a Tyr-D-Ala-Gly-Phe opioid message sequence showed good opioid affinity (1 nM at both delta and mu opioid receptors) and bioactivity (34.9 nM in MVD and 42 nM in GPI/LMMP bioassays).

摘要

一种与“氨基芬太尼”偶联的脑啡肽类似物已被合成,并在μ和δ阿片受体上测试了其生物活性。代表芬太尼结构衍生物的氨基芬太尼是通过在二异丙基乙胺(DIPEA)存在下,用邻苯二甲酰保护的β-丙氨酰氯对1-(2-苯乙基)-4-(N-苯胺基)哌啶进行酰化反应,然后用水合肼脱保护而合成的。氨基芬太尼也已成功地用异氰酸乙酯、各种酸酐进行酰化,以进一步研究这些新型芬太尼衍生物的构效关系。在新衍生物中,带有Tyr-D-Ala-Gly-Phe阿片信息序列的化合物7显示出良好的阿片亲和力(在δ和μ阿片受体上均为1 nM)和生物活性(在MVD生物测定中为34.9 nM,在GPI/LMMP生物测定中为42 nM)。
