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)
