  Essential structure of opioid κ receptor agonist nalfurafine for binding to the κ receptor 2: Synthesis of decahydro(iminoethano)phenanthrene derivatives and their pharmacologies

  摘要：

  To clarify the essential structures of an opioid kappa receptor selective agonist, nalfurafine, for binding to the kappa receptor, we designed and synthesized some nalfurafine derivatives and the decahydro(iminoethano)phenanthrene derivatives with a cyclohexene moiety as a surrogate for the phenol ring. In addition to the 6-amide side chain and the 17-nitrogen substituted by a cyclopropylmethyl group, the 4,5-epoxy ring, phenolic hydroxy group, and angular hydroxy group played important roles in eliciting the binding properties of nalfurafine but these three moieties were not indispensable for binding to the kappa receptor. Moreover, the phenol ring was also not essential for the binding to the kappa receptor, and the cyclohexene moiety would play an important role in fixing the conformation of decahydro(iminoethano) phenanthrene derivatives to effectively raise the amide side chain, rendering a conformation that resembled the active one of nalfurafine.
