Benzopyrans are selective estrogen receptor (ER) beta agonists (SERBAs), which bind the ER receptor subtypes alpha and beta in opposite orientations. We have used structure based drug design to show that this unique phenomena can be exploited via substitution at the 8-position of the benzopyran A-ring to disrupt binding to ER alpha, thus improving ER beta subtype selectivity. X-ray cocrystal structures with ER alpha and ER beta are supportive of this approach to improve selectivity in this structural class. (c) 2007 Elsevier Ltd. All rights reserved.
