Abstact

Benzopyrans are selective estrogen receptor (ER) beta agonists (SERBAs), which bind the ER subtypes alpha and beta in opposite orientations. Here we describe structure-activity relationship studies that led to the discovery of bezopyran 5b. X-ray crystal structures of 5b and a non-selective analog 5c in ERalpha help explain the observed selectivity of the benzopyran platform.
