The 14-aminodihydromorphinone and codeinone series of opioid ligands have produced a number of ligands of substantial interest. To investigate the importance of the 14-substituent, a series of analogues in which the side chain length is varied and the amide and alkene functions are reduced have been prepared. Binding affinity, particularly at the mu-opioid receptor (MOR), was largely determined by
14-氨基二氢吗啡酮和可待因酮系列阿片样物质配体已经产生了许多令人感兴趣的配体。为了研究14位取代基的重要性,已经制备了一系列类似物,其中侧链长度变化并且酰胺和烯烃的功能降低。结合亲和力,特别是对μ-阿片受体(MOR)的结合亲和力很大程度上取决于侧链的芳族基团。在[35S] GTPgammaS功能测定中,具有三碳侧链的配体比其长链对应物更有效,而较短的二碳链类似物具有更高的MOR功效,这一作用已在体内得到证实。在该系列中观察到耐洗涤结合,并且似乎与侧链长度无关。
