制备方法与用途

生物活性

(R)-Equol 是 ERα 和 ERβ 的激动剂,其 Ki 值分别为 27.4 nM 和 15.4 nM。

靶点

Ki: 27.4 nM (ERα), 15.4 nM (ERβ)

体外研究

(R)-Equol 是 ERα 和 ERβ 的激动剂,其 Ki 值分别为 27.4 nM 和 15.4 nM。在体外实验中,(R)-Equol 对 MDA-MB-231 细胞的侵袭能力表现出剂量依赖性的抑制作用,在最高浓度(50 μM)时尤为显著。暴露 48 小时后,50 μM (R)-Equol 可使细胞侵袭减少约 62%(p=0.009,与未处理组相比)。同时,(R)-Equol 还能显著下调基质金属蛋白酶-2 (MMP-2) 的表达(p=0.035)。

体内研究

喂食 (R)-Equol 的动物在时间上形成的可触及肿瘤数量明显减少(P=0.002)。此外,(R)-Equol 喂食组的每只大鼠形成的可触及肿瘤数量显著低于 S-(-)equol 组(P=0.008),(R)-Equol 喂食动物比对照组少 43% 的肿瘤,并且这一差异具有高度统计学意义(P=0.004)。与对照组相比,喂食 (R)-Equol 的动物每只携带肿瘤的动物的肿瘤数量显著减少(3.3±0.4 对于对照组为 5.5±0.5,P=0.004)。在解剖检查时,(R)-Equol 喂食大鼠平均每只的肿瘤重量显著减轻(5.3±1.1 mg 对比对照组 9.9±1.4 mg,P=0.04),并且 (R)-Equol 的喂食还导致肿瘤发生时间显著延长(P=0.003)。

    名称:
    Equol, a natural estrogenic metabolite from soy isoflavones
    摘要:
    Equol is a metabolite produced in vivo from the soy phytoestrogen daidzein by the action of gut microflora. It is known to be estrogenic, so human exposure to equol could have significant biological effects. Equol is a chiral molecule that can exist as the enantiomers R-equol and S-equol. To study the biological activity of racemic (+/-)-equol, as well as that of its pure enantiomers, we developed an efficient and convenient method to prepare (+/-)-equol from available isollavanoid precursors. Furthermore, we optimized a method to separate the enantiomers of equol by chiral HPLC, and we studied for the first time, the activities of the enantiomers on the two estrogen receptors, ERalpha and ERbeta. In binding assays, S-equol has a high binding affinity, preferential for ERbeta (K-i[ERbeta] = 16 nM; beta/alpha = 13 fold), that is comparable to that of genistein (K-i[ERbeta] = 6.7 nM; beta/alpha= 16), whereas R-equol binds more weakly and with a preference for ERalpha (K-i[ERalpha] = 50 nM; beta/alpha = 0.29). All equol isomers have higher affinity for both ERs than does the biosynthetic precursor daidzein. The availability an the in vitro characterization of the equol enantiomers should enable their biological effects to be studied in detail. (C) 2004 Elsevier Ltd. All rights reserved.

    Subject of the invention is a method for enantioselective production of an isoflavane from an isoflavone, comprising the steps: (a) selectively reducing the isoflavone, such that the 4-keto group of the isoflavone is converted to a 4-hydroxy group, and the 2,3-double bond of the isoflavone is converted to a 2,3-single bond, thereby obtaining a 4-hydroxy intermediate, and (b) reacting the 4-hydroxy intermediate with a chiral reagent, such that a chiral group is covalently attached to the C4-position of the 4-hydroxy intermediate, thereby obtaining a chiral intermediate. The invention also relates to intermediates of formulae (IV), (V), (VI) and (VII) obtainable in the inventive process.

    Abstract

    Equol, a nonsteroidal estrogen produced from the metabolism of the isoflavonoid phytoestrogen daidzein, has been synthesized as both enantioenriched forms based on MacMillan’s α-arylation of carbonyl compound mediated by amino acid derived indazolidinones and copper precatalysts. The natural form of (S)-equol and its enantiomer (R)-equol have been synthesized in 8 steps from 2,4-dimethoxybenzaldehyde with good enantiomeric purity (90% ee and 90% ee, respectively).
