• Estrogen potentiating activity of two spiro compounds having approximately similar molecular dimensions to stilbestrol
  作者：Neil S. Doggett、David J. Bailey、Tariq Qazi

  DOI：10.1021/jm00212a031

  日期：1977.2

  Pharmacological investigation of members of a series of synthetic spiro derivatives with similar molecular dimensions to stilbestrol revealed that two compounds, spiro[cyclohexane-1,2'-tetralin]-1,4'-dione and spiro[cyclohexane-1,2'-indan]-1,4'-diol, exhibited a marked ability to potentiate stilbestrol at doses which had no intrinsic estrogenic activity. It is postulated that such compounds may be of use in reducing the side effects associated with estrogen therapy.
