2qtu | pdb_00002qtu
Estrogen receptor beta ligand-binding domain complexed 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 synthesis of a late stage intermediate that allowed us to combine A-ring and C-ring modifications and carry out simultaneous SAR studies at both positions. Modification of both positions proved additive, maintaining affinity and improving ERbeta selectivity up to 83-fold. An X-ray cocrystal structure confirms the previously observed binding mode in ERbeta.
