Benzopyrans are selective estrogen receptor (ER) 0 agonists (SERBAs), which bind the ER subtypes a and 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 ER alpha help explain the observed selectivity of the benzopyran platform. (c) 2007 Elsevier Ltd. All rights reserved.

chalcone derivatives and by examining the structure-activity relationships on the inhibition of rat lens aldosereductase as well as on antioxidant effects. A series of 35 flavonoid derivatives were synthesized by Winget's condensation, oxidation, and reduction of appropriate acetophenones with appropriate benzaldehydes. The inhibitoryactivity of these derivatives on rat lens aldosereductase and their
