order to detect novel σ receptor ligands, the rigid spiro[[2]benzopyran-1,1′-cyclohexan]-4′-one was connected with amino moieties derived from σ2 receptor preferring lead compounds resulting in mixtures of trans- and cis-configured amines 6, 18, and 27. In a four step synthesis the methyl acetals 6 were converted into fluoroethyl derivatives 13 and 30. The most promising σ2 receptor ligand is the methyl
为了检测新的σ受体配体,所述刚性螺[[2]苯并吡喃-1,1'-环己烷] -4'-酮与来自σ衍生的氨基部分被连接2受体宁愿造成的混合物铅化合物反式-和顺式-型胺6,18,和27。在四步合成中,将甲基乙缩醛6转化为氟乙基衍生物13和30。最有前途的σ 2受体配体是甲基缩醛6A轴承2,4-二甲苄氨基部分。氟乙基衍生物13c和13d揭示了高σ 1在σ亲和力,但中度选择性2亚型。在小鼠中,13C和13D显示抗异常性疼痛活性在比基准的强σ 1拮抗剂BD-1063(34)。由于抗异常性疼痛活性13C只能部分地由σ逆转1激动剂PRE-084(35),但假定第二机构有助于其总体止痛作用。与此相反,非对映体其的抗异常性疼痛效果13D可以完全由σ说明1拮抗作用。
