以多酚类化合物和多取代苯乙酸类化合物为原料, 用“一锅法”合成了24个7-羟基异黄酮类化合物|并从“一锅法”制得的3d, 3g经脱除甲基得到两个2-羟基取代的异黄酮化合物4a4b. 雌激素受体(Estrogen receptors, ERs)的选择性结合活性试验表明: 26个化合物(包括4个新化合物3r, 3s, 3u3v)中, 9个化合物与ERβ相对于ERα的选择性作用强于染料木素(Genistein)|发现7,8-二羟基异黄酮类化合物与ERβ相对结合能力高于相应7-羟基异黄酮类化合物|4取代基对化合物与ERβ结合相对于ERα的选择性影响从大到小为: H>Cl>F>OH|2, 3及5位取代基降低异黄酮对ERα和ERβ的亲和性.

关键词: 7-羟基异黄酮, 雌激素受体, 选择性激动, 构效关系

Twenty six 7-hydroxylisoflavones, including four new compounds 3r, 3s, 3u and 3v, were successfully synthesized. Among which twenty four, 3a3x, were directly given by “One-Pot” strategy from polyphenolic compounds and substituted phenylacetic acids. 2-Hydroxylisoflavones 4a and 4b were further developed from 2-methoxylisoflvones 3d and 3g by demethylation. Nine out of twenty-six synthesized compounds exhibited higher selectivity for estrogen receptor ERβ than genistein|7,8-dihydroxylisoflavones showed better binding affinities for ERβ than 7-hydroxylisoflavones|4-substituents of isoflavones influenced relative binding affinities (RBA) of ERβ/ERα in the order: H>Cl>F>OH|2, 3 and 5-substituents reduced the binding affinity to both ERα and ERβ.

Key words: 7-hydroIsoflavone, estrogen receptor, binding affinity, structure-activity relationship (SAR)
