We designed highly selective non-peptide agonists for the delta-opioid receptor. On the basis of the "message-address" concept in this field and the accessory site hypothesis, a novel class of heterocycle-fused octahydroisoquinoline derivatives were synthesized. One of these compounds [(4aS*,12aR*)-4a-(3-hydroxyphenyl)-2-methyl-1,2,3,4,4a,5,12, 12a -octahydropyrido[3,4-b]acridine, TAN-67 (2)] showed
我们为δ阿片受体设计了高度选择性的非肽激动剂。基于该领域的“消息地址”概念和辅助位点假说,合成了一类新的杂环稠合八氢异喹啉衍生物。这些化合物之一[(4aS *,12aR *)-4a-(3-羟基苯基)-2-甲基-1,2,3,4,4a,5,12,12a-八氢吡啶并[3,4-b] ac啶,TAN-67(2)]对豚鼠大脑中的δ-阿片样物质受体具有很高的选择性(Ki = 1.12 nM),对μ-阿片样物质受体的亲和力低2070倍,而对阿片类药物的亲和力低1600倍。 κ阿片受体。TAN-67是一种有效的δ阿片受体激动剂,在小鼠输精管测定中的IC50值为6.61 nM,被纳曲酮(NTI)逆转(Ke = 0.21)。此外,TAN-67在小鼠乙酸腹部收缩试验中皮下给药后显示具有抗伤害感受活性,该试验被NTI(δ1和δ2拮抗剂)和7-苄基纳曲酮(δ1拮抗剂)拮抗,但纳曲本没有(δ2-拮抗剂)。这种全身适用的
