  Synthesis and Characterization of 3-Arylquinazolinone and 3-Arylquinazolinethione Derivatives as Selective Estrogen Receptor Beta Modulators

  摘要：

  On the basis of the stucture of genistein, a new series of 3-arylquinazolines was prepared and tested for their estrogen receptor (ER) alpha and beta affinities. 5,7-Dihydroxy-3 -(4-hydroxyphenyl)-4(3H)-quinazolinone (1aa) acts as an agonist on both ER subtypes. It has 62-fold higher binding affinity [IC50(ER beta) = 179 nM] and 38-fold higher functional potency in a transcription assay [EC50(ER beta) = 76 nM] with ER beta than with ER alpha, thus improving upon the selectivity of genistein. All of the analogues showed preferential binding affinity for ER. Many are also more potent in activating transcription by ER beta than by ER alpha. Transformation of the C=O functionality at position 4 into a C=S group provided 5,7-dihydroxy-3-(4-hydroxyphenyl)4(3H)-quinazolinethione (1ba), which acts as an agonist on both ER subtypes but has 56-fold higher binding affinity for ER beta over ER alpha [IC50(ER beta) = 47 nM] and 215-fold higher potency in the transcription assay [EC50(ER beta) = 13 nM]. These ER beta-selective compounds may represent valuable tools in understanding the differences in structure and biological function of ER beta and ER alpha.
