  Indazole Estrogens:  Highly Selective Ligands for the Estrogen Receptor β

  摘要：

  The estrogen receptors, ERalpha and ERbeta, are important pharmaceutical targets. To develop ERbeta-selective ligands, we synthesized a series of nonsteroidal compounds having a phenyl-2H-indazole core with different groups at C-3. Several of these show high affinity and good ERbeta selectivity, especially those with polar and/or polarizable substituents at this site (halogen, CF3, nitrile); the best compounds have affinities for ERbeta comparable to estradiol, with ERbeta affinity selectivity > 100. This potency and ERbeta selectivity is also seen in cell-based transcriptional assays, where several compounds showed ERbeta efficacies equivalent to that of estradiol with ERbeta potency selectivities of 100. These compounds might prove useful as selective pharmacological probes to study the biological actions of estrogens mediated through ERP, and they might lead to the development of useful pharmaceuticals. These findings also contribute to an evolving pharmacophore that characterizes certain nonsteroidal ligands having high ERbeta subtype affinity and potency selectivity.

  A new efficient copper-catalyzed intramolecular amination reaction has been developed to readily synthesise a wide variety of multi-substituted 2H-indazole and 1H-pyrazole derivatives from easily accessible starting materials under mild conditions. A highly selective ligand for estrogen receptor β was prepared in three steps by employing this method.
