实施例7：

本发明化合物的抗肿瘤活性测试

1.实验原理

活细胞线粒体中的琥珀酸脱氢酶能使外源性MTT还原为不溶于水的蓝紫色结晶甲瓒(Formazan)并沉积在细胞中，而死细胞无此功能。二甲基亚砜(DMSO)，其作用是能够溶解细胞中甲瓒，用酶标仪测定其光吸收值就可反映活细胞数量。

2.抗肿瘤活性实验

试样：实施例化合物

细胞系：肝癌细胞系HepG2和肺癌细胞系A549

试剂：0.5％MTT溶液，RPMI 1640培养液、新生牛血清；胰酶；96孔培养板；二甲基亚砜；

仪器：超净台、培养箱、Perkin Elmer全自动多功能酶标仪

实验步骤：

1)将指数生长期的HepG2和A549细胞(2×10 ⁵个/mL)接种到96孔板上培养过夜，然后用设定浓度的药物处理细胞。

2)药物处理24小时后，向每个孔中加入20μL MTT试剂(5mg/mL)。5％CO₂，37℃孵育4小时后，吸出培养基的上清液，向每个孔中加入150μL DMSO溶解甲瓒晶体。

3)采用双波长法测定，通过酶标仪测定在492和630nm的吸光度。

3.抗肿瘤活性评价

1)细胞活力抑制率计算

细胞活力抑制率＝[1-加药(OD₄₉₂-OD₆₃₀)/对照(OD₄₉₂-OD₆₃₀)]×100(％)

2)IC₅₀值计算

试样浓度与细胞抑制率线性回归，利用软件计算试样对细胞的半数抑制浓度IC₅₀值。

表1细胞活力抑制IC₅₀值

由表1可以看出，对于HepG2细胞，有33个化合物的IC₅₀值低于10μM；对于A549细胞，有26个化合物的IC₅₀值低于10μM。并且，对于HepG2细胞，有11个化合物表现出了优于阳性对照阿霉素的活性；对于A549细胞，有34个化合物表现出了优于阳性对照阿霉素的活性。可见，该类结构新颖的内酰胺化合物具有优异的抗癌活性。
