(七)实验预示的结论及可能的问题和建议
1.实验检验了中药提取液对人非小细胞肺癌细胞株 (A549), 人大肠癌细胞株 (HT29), 人前列腺细胞株 (PC3), 人成纤维肉瘤细胞株 (HT1080), 人宫颈癌细胞株(Hela), 人乳腺癌细胞株 (MDA-MB-231 ), 人肝癌细胞株 (HepG2) 7个不同器官细胞株的细胞毒作用。
2.由于药物在不同细胞株上的作用情况不同, 选择 4个时间点 (加药后 12hr, 24hr, 48hr, 72hr), 根据各 个细胞的具体状况, 获得了相应时间点的 IC50值。
3.中药提取液对所选的 7个细胞株的增殖都有抑制作用, 呈现很好的浓度梯度, 其中对 HT1080、 HeLa, MDA-MB-231、 A549细胞的作用较强, 对 HepG2、 HT29、 PC3细胞的作用较弱。
4.从药物开发的角度, 可继续该药物对肺癌, 宫颈癌, 乳腺癌等癌症治疗方面的研究, 同时可以考虑实验 该药物对非肿瘤细胞的细胞株是否存在细胞毒性作用。 杭州高通新药筛选中心 艾森生物

5. 化合物机理探讨:根据化合物特异性反应图谱, 中药提取液在这几个细胞株上都表现出明显的细胞毒作 用, 在 H 29和 PC3细胞上的图谱显示出 DNA Damage的细胞毒性作用特征。

( 1 )中药提取液对 A549细胞株体外迁移能力的抑制作用检测。
(见图 9)

左图为药物抑制细胞迁移曲线, 右图为平行进行的药物对细胞增殖影响的实时动态图。 其中, 横坐标表示 细胞培养及药物作用时间; 纵坐标表示标准化细胞指数(NCI)。 细胞指数提示细胞生长状态。 在细胞迁移 实验中, 其值越高, 反应迁移至下室的细胞数越多; 在细胞增殖实验中, 其值越高反映活细胞越多。 加药 浓度见图中所示。

加入的药物浓度高于 55.56ug/ml时, 对细胞有明显的毒性作用, 这种毒性作用下由于上室细胞死亡或者活 性降低, 迁移至下室的细胞数量减少。 而当药物浓度低于 55.56ug/ml时, 对细胞基本没有毒性作用, 细胞 的迁移却也受到一定的抑制, 且当抑制作用呈药物浓度依赖性, 因此该药物对 A549细胞迁移有一定的抑 制作用。

该实验说明加入不同浓度的细胞提取液, 对细胞有明显的毒性作用, 这种毒性作用下由于上室细胞死亡或 者活性降低, 迁移至下室的细胞数量减少。 但在中药提取液浓度低于 7.11mg/ml时, 在药物的作用下, 细 胞迁移量高于 control, 有刺激迁移的作用。

加入的药物浓度高于 18.52ug/ml时, 对细胞有明显的毒性作用, 这种毒性作用下由于上室细胞死亡或者活 性降低,迁移至下室的细胞数量减少。而当药物浓度低于或等于 18.52ug/ml时,对细胞基本没有毒性作用, 细胞的迁移却也受到一定的抑制, 且当抑制作用呈药物浓度依赖性, 因此该药物对 A549细胞迁移有一定 的抑制作用。

在实验前期 (20hr前), 加入药物对 MDA-MB-231细胞的迁移有一定的刺激作用。 且当药物浓度低于 0.15mg/ml时, 对细胞没有明显的毒性作用, 此时, 加入药物量越高, 对细胞迁移的刺激作用越强。 加入 的药物浓度高于 0.4mg/ml时,对细胞有比较明显的毒性作用,这种毒性作用下由于上室细胞死亡或者活性 降低, 迁移至下室的细胞数量减少。

(见图 15)
图 15 HT29细胞株体外迁移能力检测。 如图所示, 细胞浓度分别为 80k/well, 40k/well,20k/well,l Ok/well 时, HT29没有明显的细胞迁移能力, 因此无法进行药物对细胞迁移能力的抑制作用检测。
(七) 实验预示的结论及可能的问题和建议

1.项目简介
本实验采用实时心肌细胞分析系统, 在原代新生大鼠心肌细胞上, 对贵州中药提供的中药提取液进行 药物心脏安全性的检测及评估。 本实验所采用的评估参数为时间依赖性的体外心肌细胞跳动频率、 心肌细 胞跳动幅度以及心肌细胞跳动节律和波型。
2.背景介绍
2.1.研究背景
艾森生物是一家致力于研发和制造本公司拥有自主专利的以阻抗技术为基础的实时细胞检测仪的高 科技生物公司。 艾森公司所创新设计的安装于微孔板底部的微电极传感器, 可用于实时、 无标记检测细胞 状态, 具有高通量、 高精确度、 高灵敏度及可定量检测等优点。
由心脏疾病或药物心脏毒性引起的心脏功能损伤威胁着人类的健康和安全。 深入揭示重大心脏疾病发 生机制, 并在此基础上探讨新的有效防治措施, 以及在新药开发过程中, 揭示部分药物心脏毒性是心脏硏 究工作者面临的重大挑战。艾森生物与罗氏共同开发的实时心肌细胞分析系统(xCELLigence RTCACardio System), 可动态监测心肌细胞兴奋收缩偶联反应, 并实时短时程 /长时程检测并记录心肌细胞跳动电信号。 当化合物作用于心肌细胞影响细胞形态和活性, 或者导致相关通道开放程度改变, 或者引起收缩兴奋传导 性发生变化时, 可以通过实时心肌细胞分析系统进行实时监测。
该系统可用于筛选影响心肌细胞收縮兴奋传导性变化的药物, 包括离子通道和非离子通道靶点药物。 艾森公司使用小鼠胚胎干细胞诱导的心肌细胞(CorAt, Axiogenesis)和人 iPS细胞诱导的心肌细胞对超过 50种已知化合物进行了验证, 稍后又用原代大鼠心肌细胞做了补充验证。研究结果表明, 实时心肌细胞分 析系统能够可靠和定量检测心律失常化合物以及非 ERG通道和电压门控性钙通道化合物对心肌细胞的作 用。 因此, 本系统可作为一个早期药物开发过程中的化合物的心脏毒性筛査的工具, 进行相关药物高通量 筛选和药物毒性研究。 工作内容:
本项目的目标是使用阻抗检测系统, 进行药物心脏安全性的检测及评估, 评估和鉴定化合物引起的原 代大鼠心肌细胞跳动率变化的能力。
本项目中每种化合物使用 7个不同浓度进行测试, 在检测前后选定不同时间点监测细胞跳动状态, 通 过观察中药提取液对原代大鼠心肌细胞的剂量依赖性作用来评估其对原代心肌细胞跳动的影响作用。

低浓度的药物 (5.33和 lJ8mg/ml ) 在加药后 2-12小时区间内引起心肌细胞跳动频率略降低并幅度增大, 12小时候跳动恢复正常。
药物浓度低于 0.59mg/ml对心肌细胞跳动无明显影响。
4.1中药提取液对新生大鼠原代心肌细胞活性影响
(见图 20)
中药提取液: (H20 ctrl, blank et, 7.32ug/ml, 21.95ug/ml,65.84ug/ml,0.20mg/ml,

中药提取液抑制原代心肌细胞活性动态检测。 上图为细胞生长及药物作用实时动态图。 其中, 横坐标表示 细胞培养及药物作用时间; 纵坐标表示标准化细胞指数(NCI)。 细胞指数提示细胞生长状态。 其值越高反 映活细胞越多。 箭头所指为加药吋间, 加药浓度见图中所示。 该图显示细胞在药物作用下的药物浓度依赖 性动态反应曲线, Ctrl为阴性对照, 显示正常的细胞生长动态曲线。 (注: H20 Ctrl对照孔加入 10% (与最 高浓度的药物原液量相同) 的 H20)
从中药提取液对新生大鼠原代心肌细胞活性影响的结果可见, 当给予高浓度药物时(16mg/ml), 一段时间 后细胞指数迅速下降, 反映高浓度药物具有明显细胞毒性, 可导致细胞形态变化、 贴壁不良甚至死亡。 而当药物浓度低于 5.32mg/ml时, 药物对细胞活性的影响不明显。 但是此浓度的药物却会引起心肌细胞在 跳动频率和跳动幅度上一定程度的变化。

4. 4中药提取液影响跳动频率 (Beating rate ) 的作用
(见图 22)
该图为心肌细胞跳动频率的中药提取物药物浓度和时间依赖性变化量效关系。使用的参数为标准化跳动频 率 (Normal ized Beat ing Rate, NBR) , 参数计算方法为选择时间点的跳动频率与标准化时间点 (Omin ) 的跳动频率的比值。
其中图 A为加药 lh以内细胞跳动频率的变化过程; 图 B为药物在加药前 lOmin至加药后 24h之间全程细 胞跳动频率变化过程。
从图中可见, 加药前 lOmin内细胞跳动频率一致, 均一性好。 加药后短期内药物对细胞跳动无明显影响, 2hr后高浓度药物引起细胞跳动频率降低, 直至 6hr后跳动完全停止, 5. 33ing/rnl药物在一段时间段内引 起跳动频率略降低, 药物浓度小于 1. 78mg/ml对细胞跳动则无明显影响。 说明该药物高浓度时对有明显的 影响心脏跳动作用, 低浓度对心脏跳动作用无严重影响。
4. 5中药提取液影响跳动幅度 (Ampl itude) 的作用
(见图 23)
该图为心肌细胞跳动幅度的药物浓度和时间依赖性变化。 使用的参数为标准化跳动幅度 ( Normal ized

从图中可见, 加药前 lOmin内细胞跳动幅度稳定, 加药后短期内药物对细胞跳动幅度无明显影响, 2hr后 高浓度 16mg/ml药物引起细胞跳动频率降低, 直至 6hr后跳动完全停止, 5. 33mg/ml药物引起跳动频率略 降高, 药物浓度小于 1. 78mg/ml对细胞跳动则无明显影响。 说明该药物高浓度时对有明显的影响心脏跳动 作用, 低浓度对心脏跳动作用无严重影响。 杭州高通新药筛选中心 艾森生物

5. 1该药物在高浓度时 (16mg/ml) 迅速影响细胞活性, 导致细胞死亡。
5. 2该中药以浓度依赖的方式影响原代新生大鼠心肌细胞跳动的频率和幅度。高浓度(16mg/ml)时会导致 细胞在 6hr左右以后停止跳动; 而中等浓度(5. 33mgAil ; 1. 78mg/ml ) 时可以引起细胞在 6hr左右以后跳 动频率略变慢, 幅度略增大。 说明该药物高浓度时对有明显的影响心脏跳动作用, 低浓度对心脏跳动作用 无严重影响。
5. 3未见药物引起的特异性离子通道相关心肌细胞跳动波形。 以上结果仅供参考, 具体机制还需进一步筛选研究。 实验记录信息
