We used the derivatives to do the MTT assay test and to discuss the SAR, the result teld us the isoprenyl group and the 3,4-olefinic bond of osthol is essential for its activity,and the isoprenyl group at position 8 had the better cytotoxicity. When osthol and demethylsuberosin reacted with ferulic acid to form the derivatives of (26) and (35) have the better effect of anti-cancer and IC50 value than osthol.

所以我们选择蛇床子素进行结构上的修饰并与姜黄素的部分结构形成的化合物ferulic acid结合合成出一系列的衍生物，进行抗癌细胞毒杀活性测试来探讨其结构与活性的关系，发现osthol上的isoprenyl group对於抗癌活性有重要的影响，且isoprenyl group位於C8的位置对於抗癌活性有较好的表现。

The invention comprises the following steps: summating and counting the added playing times of the acoustic frequency song in the portable media device when playing any acoustic frequency song; updating and saving in the current playing acoustic frequency song list; displaying the first acoustic frequency song list and the second acoustic frequency song list for the users in the picture according to the summated and counted acoustic frequency song playing frequency and the updated and saved current playing acoustic frequency song list when the user requests to play the song and uses the quick search music function; displaying the acoustic frequency song list according to the high sequence of the user playing frequency.
