Description
技术领域
本发明属于药用化合物开发和应用技术,特别是涉及一种淫羊藿素类似物及其制备方法和应用。
背景技术
多发性骨髓瘤(MM)的特征是恶性浆细胞的克隆扩增,是一种恶性疾病。全世界每年诊断出MM的病例超过100000例,占所有恶性肿瘤的1~2%和血液学肿瘤的10%。多发性骨髓瘤(MM)的特征在于细胞增殖不受控制,导致整个骨髓中积累了突变的浆细胞(PC)。过多的异常PC产生会导致骨髓过度拥挤,并阻碍其他正常和健康血细胞的完全形成。另外,多发性骨髓瘤的特征是染色体异质性和一系列基因中的大量突变,这两种突变均难以靶向该疾病。MM在许多地区的发病率和患病率正在上升,并且已经经历了复发过程,这使其成为一项重大且不断增长的医学挑战。多发性骨髓瘤的治疗通常包括皮质类固醇,蛋白酶体抑制剂(例如来那度胺,沙利度胺),免疫调节或单克隆抗体的组合。尽管新的治疗方法和药物改善了结局,但大多数患者最终还是复发了并且具有多重耐药性。因此,扩展现有的治疗应用并设计其他有效的疗法是迫切且未得到满足的需求。
从植物中发现生物活性化合物一直是研究人员关注的焦点,许多重要的化合物都是从植物、微生物代谢产物和海洋生物中开发出来的。天然产物在药物开发中起着关键作用,特别是在抗肿瘤药的研究中,超过60%的抗肿瘤药与天然产物密切相关。黄酮是一大类天然产物,具有广泛的生物活性。这些化合物大多数具有差的溶解度,低的生物利用度和弱的生物活性,这限制了它们的药物开发。淫羊藿素是淫羊藿中主要活性成分淫羊藿苷的水解产物,是异戊烯基取代的黄酮醇,具有多种生物活性,例如抗肿瘤、调节骨代谢、神经保护作用、抗炎和抗氧化作用。淫羊藿素已被用作临床候选天然小分子药物来治疗肿瘤。但是,由于淫羊藿素的抗肿瘤效果一般,限制了其在临床的应用。

实验步骤:
按照CCK8法进行测定化合物对多种癌细胞增殖的抑制作用,并得出化合物抑制细胞增殖活性的半数抑制浓度IC50。
1)将细胞在37%的5.0%二氧化碳气氛中孵育,细胞以8×103 cells/孔的密度接种在96孔板中,并在含有8%胎牛血清的100μl培养基中培养12小时。将目标化合物和阳性对照溶于100μl培养基中,加入不同浓度的目标化合物,在37℃孵育72小时,加入10μl CCK8试剂。培养后,可以通过Synergy H1(BioTek)测定吸光度。由对照百分比和浓度的对数曲线确定IC50值。所有样品和对照均进行三次重复测试。
2)将对数生长期细胞以8×103 cells/孔接种于96孔板,置于37 ℃,5% CO2条件下培养,直至细胞90%融合后,用无血清的DMEM培养基或RPMI-1640培养基或L-15培养基或F12K培养基或MEM培养基或F-12培养基或IMDM培养基孵育2 h使细胞同步化。
3)向培养板加入梯度稀释的不同浓度的待测化合物溶液100 μL,将培养板在37 °C,5% CO2培养箱条件下孵育72小时。
4)孵育结束前4 h,每孔加入10 μL CCK8溶液。孵育结束后,用酶标仪测定OD450,抑制率=(对照组OD值-实验组OD值)/对照组OD值×100%。
5)得出数据后,GraphPad Prism 8拟合得出IC50。
本发明中的化合物对多种癌症细胞增殖活性的试验进行测定,测得的IC50值见表1。
