• Flavonoids: structural requirements for antiproliferative activity on breast cancer cells
  作者：Christelle Pouget、Fabienne Lauthier、Alain Simon、Catherine Fagnere、Jean-Philippe Basly、Christiane Delage、Albert-José Chulia

  Several classes of flavonoids (flavones, flavanones, 2'-hydroxychalcones and flavan-4-ols) having a variety of substituents on A ring were investigated for their antiproliferative activity against MCF-7 human breast cancer cells. Structure-activity relationships of these compounds were discussed. 2'-hydroxychalcones and methoxylated flavanones were found to be potent inhibitors of MCF-7 cells growth

  研究了在A环上具有各种取代基的几类类黄酮（类黄酮，黄烷酮，2'-羟基查耳酮和黄烷-4-醇）对MCF-7人乳腺癌细胞的抗增殖活性。讨论了这些化合物的构效关系。发现2'-羟基查耳酮和甲氧基黄酮是MCF-7细胞生长的有效抑制剂，而黄酮和flavan-4-ols除7,8-二羟基黄酮外似乎是弱抑制剂。
