以下通过试验例来具体说明本发明的有益效果。

试验例1、抗肿瘤研究

1、实验肿瘤细胞株

人乳腺癌mb468细胞株、人乳腺癌skbr3细胞株、人乳腺癌mb231细胞株、小鼠黑色素瘤a375细胞株均由四川大学生物治疗国家重点实验室提供，以上肿瘤细胞均冻存于四川大学生物治疗国家重点实验室。

2、实验方法

2.1细胞的准备及处理

4种肿瘤细胞均培养于含10％灭活新生小牛血清的rpmi-1640培养液，37℃、5％co2培养箱中生长至80％细胞融合，用0.1％胰酶溶液消化，制成单细胞悬液，调整细胞浓度为5×104个/ml，均匀接种于96孔微量培养板中，每组3个复孔，100μl/孔，置37℃饱和湿度、5％co2孵箱内培养24h后，正常对照组加入含等量的培养液；加入浓度梯度的受试药物(100、50、25、12.5、6.25μg/ml)，每个浓度设3个复孔，实验平行2次。待药物与细胞作用24h后，每孔加入10μlmtt溶液(5mg/ml)，继续培养4h后每孔加入100μldmso，振荡混匀，使结晶物充分溶解，在酶标仪490nm波长处测其吸光度值(a值)，各个浓度组取其平均值。

2.2肿瘤细胞增殖抑制率的测定

按下列公式计算细胞增殖抑制率：细胞增殖抑制率(％)＝(1－试验组a值/对照组a值)×100％。所有实验数据采用spss13.0进行统计分析。实验结果采用probit求得ic50值。

3、实验结果

表1本发明化合物对受试细胞生长的抑制情况

实验结果表明，本发明化合物具有优异的抗肿瘤效果。(以上数值大于50才具有抗肿瘤效果)

综上所述，本发明化合物的制备方法简便、反应温和、收率高，并且具有优良的抗肿瘤活性，具有广阔的市场应用前景。
