Among a series of C-alkylated analogs of the weak mu opioid ligand spiro[benzofuran-3(2H),4'-1'-methylpiperidine-7-ol] (1), the 2-methyl, 2-ethyl, and cis 3'-methyl analogs, namely compounds (+/-)2, (+/-)-3, and (+/-)-4, showed much enhanced mu-affinities, with (+/-)-4 being almost as potent as (-)-morphine; while the trans 3'-methyl analog (+/-)-5 remained a weak mu-binder. Energy calculations and
在弱μ阿片样物质配体螺[苯并呋喃-3(2H),4'-1'-甲基哌啶-7-ol](1)的一系列C烷基化类似物中3'-甲基类似物,即化合物(+/-)2,(+/-)-3和(+/-)-4,显示出更高的mu亲和力,其中(+/-)-4几乎与如(-)-吗啡有效; 反式3'-甲基类似物(+/-)-5仍然是弱的mu-binder。能量计算和NMR数据表明,化合物2-4有利于苯基-轴向构象,而化合物1和5有利于苯基-赤道构象。
