Several 2,3-diarylbenzopyrans have been evaluated in an ovariectomized
rat model and found to exhibit tissue selective estrogen agonist acti
vity on bone and serum lipid parameters. A structural model that accou
nts for the pharmacological similarity of these benzopyrans and the be
nzothiophene SERM, raloxifene, is proposed. Copyright (C) 1996 Elsevie
