木樨榄苷类化合物及其在制备抗肿瘤药物中的应用
技术领域
本发明属于化学药物技术领域，具体涉及木樨榄苷类化合物及其在制备抗肿瘤药物中的应用。
背景技术
肿瘤是世界上严重威胁人类健康的慢性疾病。木樨榄苷类化合物(Oleoside-typed glucosides)具有重要的细胞生物学功能，其典型化合物橄榄苦苷已被证实有抗肿瘤作用，且对正常细胞无明显毒性，但其抗肿瘤效果并不出众。目前该类化合物的研究尚不深入，因此，寻找高效、高选择性和药学性质良好的木樨榄苷类化合物具有重要的研究意义和应用前景。
天然产物是新药先导化合物的重要源泉，对天然活性化合物进行化学合成和改性研究又是实现创新药物研究的关键环节和重要课题。研究表明木樨榄苷类化合物有作为一类新型的抗肿瘤药物的潜质。针对其C-7位的修饰相对简便且活性增强的效果明显。

实施例2
本发明木樨榄苷类化合物在制备抗肿瘤药物中的应用
分别将上述化合物4-1～4-13及化合物5-1～5-13作为受试化合物，测试其对A549、HGC27、HepG2、A498、RAW、THP-1、Raji细胞毒性。
贴壁细胞(A549、HGC27、HepG2、A498、RAW)以CCK-8试剂盒检测，具体实验步骤为：取培养各细胞，消化并调整细胞浓度至4*104细胞/mL浓度，以100μL/孔分别接种于96孔板，将培养板放在培养箱(37℃，5％ CO2)中预培养4h。向每个细胞系分别加入终浓度为5μM的受试化合物，等体积的DMSO作为阴性对照，37℃、5％ CO2条件下培养48h。弃去各孔上清，每孔加入100μL溶液(10％CCK-8溶液+90％培养基)，细胞培养箱内继续孵育1h。酶标仪测定450nm吸光度，计算各样品各细胞系活率，计算公式为：细胞存活率＝[(As-Ab)/(Ac-Ab)]×100％，As为实验孔(含有细胞的培养基、CCK-8、待测药物)的吸光度，Ac为对照孔(含有细胞的培养基、CCK-8、没有待测药物)的吸光度，Ab为空白孔(不含细胞和待测药物的培养基、CCK-8)的吸光度。
悬浮细胞(THP-1、Raji)以乳酸脱氢酶细胞毒性检测试剂盒检测，具体实验步骤为：取培养各细胞，消化并调整细胞浓度至4*104细胞/mL浓度，以150μL/孔分别接种于96孔板，将培养板放在培养箱(37℃，5％ CO2)中预培养4h。向每个细胞系分别加入终浓度为5μM的受试化合物，等体积的DMSO作为阴性对照，37℃、5％ CO2条件下培养48h。在“样品最大酶活性对照孔”中加入原有培养液体积10％的LDH释放试剂，继续在细胞培养箱中孵育1h。将细胞培养板用多孔板离心机400g离心5min，分别取各孔的上清液100μL，加入到一新的96孔板相应孔中。各孔分别加入60μL LDH检测工作液，混匀并室温(约25℃)避光孵育30min，在490nm处测定吸光度。细胞存活率(％)＝1-(处理样品吸光度－样品对照孔吸光度)/(细胞最大酶活性的吸光度－样品对照孔吸光度)×100。
抑制率试验结果见表2。
