title: Exploration of the bicyclo[3.3.1]nonane system as a template for the development of new ligands for the estrogen receptor.
abstract: Three novel structural motifs based on a bicyclo [3.3.1]nonane template were examined as new ligands for estrogen receptor (ER). Type III compounds emerged as the most promising leads for developing high-affinity ER ligands, but they showed little selectivity for either ER subtype. Type II compounds, on the other hand, despite their lower affinity, exhibited significant ERbeta binding selectivity.
