  Synthesis and evaluation of 4-(substituted styryl/alkenyl)-3,5-bis(4-hydroxyphenyl)-isoxazoles as ligands for the estrogen receptor

  摘要：

  A series of 3,5-bis(4-hydroxyphenyl) isoxazoles bearing a styryl/alkyl vinyl group at the 4-position were prepared and evaluated as ligands for the estrogen receptor-alpha (ER alpha). The target compounds were prepared using the Suzuki reaction to couple an iodo-isoxazole intermediate with a series of styryl/alkenyl boronic acids, followed by O-demethylation. The products were evaluated for their estrogen receptor-alpha ligand binding domain (ER alpha-LBD) binding affinity using a competitive binding assay. The 4-(4-hydroxy-styryl) derivative 4 h displays binding properties similar to those of the previously described pyrazole class of ER ligands, indicating that the ER alpha-LBD tolerates the presence of the added vinyl group at the 4-position of the isoxazole ring.
