Abstract:

In the present study, we developed a simple approach for the structural modifications of kaempferol (1). A new compound, 3,5-dihydroxy-2-(4-hydroxyphenyl)-6,8,8-tris(3-methylbut-2-en-1-yl)-4H-chromene-4,7(8H)-dione (5) together with three known compounds, 8-prenylkaempferol (2), 6-prenylkaempferol (3) and 6,8-diprenylkaempferol (4), were synthesized under different reaction conditions. All of derivatives were synthesized in a structural modification way for the first time. Their structures were primarily elucidated by NMR and MS analyses. Compounds 2, 3 and 5 exhibited prominent cytotoxic activity against MDA-231 (IC50 values were 9.45±0.20μM, 7.15±0.37 μM and 6.92±0.30 μM, respectively) and MCF-7 (IC50 values were 10.08±0.57μM, 10.04±0.23 μM and 2.15±0.20 μM,respectively) breast cancer cells.
