Estrogen receptor alpha ligand-binding domain complxed to a benzopyran ligand
|
Overview
Benzopyrans are selective estrogen receptor (ER) beta agonists (SERBAs), which bind the ER subtypes alpha and beta in opposite orientations. Here, we describe the syntheses of cyclopentanone and cyclohexanone, intermediates for SAR studies of the C-ring on the benzopyran scaffold., Modification of the C-ring disrupts binding to ERalpha, thus improving, ERbeta selectivity up to 100-fold. X-ray cocrystal structures confirm, previously observed binding modes.
