技术领域
[0001] 本发明属于药物技术领域,具体涉及倍半萜内酯scaberol C硫醚衍生物及其制备方法和应用。
相关背景技术
[0002] 细胞内氧化应激与多种疾病如癌症、炎症和神经退行性疾病具有紧密的联系。尤其在癌细胞内,体现为ROS和氧化应激会诱导癌症的发生,而肿瘤细胞却比正常细胞产生更多的ROS,同时TrxR和GSH等抗氧化防御系统在恶性肿瘤中表达量也随之大大增加,而且这种高表达的抗氧化防御系统对于肿瘤细胞的生存和进展至关重要。细胞内氧化应激的程度主要依赖于ROS生成速率和抗氧化防御系统的活性之间的平衡,因此,针对肿瘤细胞内具有更高的ROS水平这一特性,研究人员已开发出了许多促ROS的生成或降低细胞内ROS清除能力的化疗试剂,从而将细胞内氧化应激推向临界点并达到选择性杀死肿瘤细胞的目的。
[0003] scaberol C可通过化学修饰的方法从地胆草全草粗提物中获得,其衍生物具有显著的抗肿瘤活性且毒性较低。前期研究的构效关系表明α‑亚甲基‑γ‑丁内酯片段是这类倍半萜内酯发挥抗肿瘤活性的关键药效团(J.Nat.Prod.2022,85,352‑364;Eur.J.Pharmacol.2022,925:174989)。但是α‑亚甲基‑γ‑内酯作为Michael加成受体片段,具有共价化合物共同的短处,其与体内的亲核中心结合选择性差,血浆中稳定性差。这大大限制了这类含α‑亚甲基‑γ‑丁内酯片段的倍半萜内酯的应用。
[0004] 硫醚作为一种在药学中十分重要的官能团,经常被引入到药物分子中,用以改善药物分子的理化性质,增强其生物活性,增强药物分子的亲和力和稳定性。

[0242] (3)阳性对照物:顺铂。
[0243] 2.实验方法:
[0244] (1)受试药物的配制:准确称取各受试样品1‑2mg,用DMSO配置成50mM的母液,用基础培养基配制成不同的浓度的工作液。
[0245] (2)细胞增殖抑制实验:取对数生长期细胞,接种到96孔板中,培养过夜后,分别加入不同浓度的化合物孵育24h,然后每孔加入20μL的MTT共孵育4h,弃上清,加入DMSO 150μL,振荡溶解10min,采用酶标仪在490nm处检测OD值,并通过GraphPad计算相应化合物的IC50值。
