  摘要：

  Purpose. Aromatase inhibitors are known to prevent the conversion of androgens to estrogens and play a significant role in the treatment of estrogen dependent diseases such as breast cancer. Some flavonoids have been reported as potent aromatase inhibitors: therefore. in an effort to develop novel anti breast cancer agents. B ring substituted flavanones with a 7-methoxy group on A ring were synthesized and tested to assess their ability to inhibit aromatase activity and to determine the optimal B ring substitution pattern.Methods. A series of flavanones was prepared by cyclisation of 2'-hydroxychalcones previously obtained by Claisen-Schmidt condensation and the aromatase inhibitory activity or these compounds was investigated using human placental microsomes and radiolabeled [1.2,6,7-H-3]-androstenedione as substrate.Results. Almost all flavanones exhibited inhibitory effect on the aromatase activity but their potency was dependent on their B ring subtitution pattern. Hydroxylation at position 3' and/or 4' enhanced the anti-aromatase activity thus, 3'.4'-dihydroxy-7-methoxyflavanone was found to he twice more potent than aminoglutethimide. the first aromatase inhibitor clinically used.Conclusions. These results indicated that these flavanones could be considered as potential anti breast cancer agents through the inhibition of aromatase activity and allowed us to select some of these Compounds as skeleton for the development of flavonoid structurally-related aromatase inhibitors.

  Abstract A facile ethylenediamine diacetate (EDDA)-catalyzed one-pot synthesis of biologically interesting flavanone derivatives from 2-hydroxyacetophenones, aromatic aldehydes, and aniline via a Mannich-type reaction is described. This synthetic method provides a rapid access to biologically interesting flavanone derivatives. To demonstrate this method, several biologically interesting natural products

  摘要 描述了一种简便的乙二胺二乙酸酯（EDDA）催化通过曼尼希型反应从2-羟基苯乙酮，芳族醛和苯胺进行一锅式合成生物学上令人感兴趣的黄烷酮衍生物的方法。这种合成方法可快速获得生物学上令人感兴趣的黄烷酮衍生物。为了证明该方法，合成了带有黄烷酮部分的几种生物学上有趣的天然产物，它们是外消旋体。 描述了一种简便的乙二胺二乙酸酯（EDDA）催化通过曼尼希型反应从2-羟基苯乙酮，芳族醛和苯胺进行一锅式合成生物学上令人感兴趣的黄烷酮衍生物的方法。这种合成方法可快速获得生物学上令人感兴趣的黄烷酮衍生物。为了证明该方法，合成了带有黄烷酮部分的几种生物学上有趣的天然产物，它们是外消旋体。
