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
已经合成了与“氨基芬太尼”偶联的脑啡肽类似物,并测试了在mu和delta类阿片受体上的生物活性。通过在DIPEA存在下用苯甲酰基保护的β-丙氨酰氯将1-(2-苯乙基)-4-(N-苯胺基)哌啶酰化,然后用水合肼脱保护,合成了代表芬太尼的结构衍生物的氨基芬太尼。氨基芬太尼也已成功地被异氰酸乙酯,各种酸酐酰化,以进一步研究这些新的芬太尼衍生物的构效关系。在带有Tyr-D-Ala-Gly-Phe阿片类信息序列的新衍生物化合物7中,阿片类药物具有良好的阿片类亲和力(δ和μ阿片受体均1 nM)和生物活性(MVD中34.9 nM,GPI / LMMP中42 nM)生物测定)。
