  B-Ring unsaturated estrogens: biological evaluation of 17α-Dihydroequilein and novel B-Nor-6-thiaequilenins as tissue selective estrogens

  摘要：

  The pharmacology and SAR of representative equine estogens is described. 17alpha-Dihydroequilenin was found to prevent bone loss after 5 weeks of oral administration to ovariectornized rats. The stereochemical significance of the D-ring and the C/D ring juncture was investigated with a series of benzothiophene-based equilenin analogues. (C) 2003 Published by Elsevier Ltd.
