四环三萜衍生物及其药物组合物和应用的制作方法

本发明属于药物学领域,具体地涉及一种四环三萜衍生物及其药物组合物和应用。



背景技术:

肿瘤作为人类健康的一大威胁一直受到广泛的关注,寻找新的抗肿瘤药物是全世界药物化学家研究的重点和热点。从天然产物(naturalproducts)中寻找新的抗肿瘤药物是抗肿瘤药物发现的主要途径之一。三萜是一类具有30个碳原子构成基本碳架的结构独特的化合物,广泛存在于自然界,已经被分离、鉴定的化合物超过了20000种,具有抗炎、抗氧化、抗增殖、抗病毒等多种生物活性。

dammarane-typetriterpenoidsfromgentianellaazurea,journalofnaturalproducts和bioactivedammaranetriterpenoidsfromthebarkofdrypetesacuminatafrompaluma,northqueensland,australia构效关系研究结果表明,母核结构的影响:原人参二醇型>原人参三醇型;糖基的影响:抗肿瘤活性研究表明,低糖链的皂苷及苷元具有更强的抗肿瘤作用。表现为:皂苷元>单糖苷>二糖苷>三糖苷>四糖苷。羟基的影响:在c-25位引入-oh或-ch3可以增强皂苷的活性。人参皂苷元ad-1,ad-2,ppd、pd、f11等能抑制人肿瘤细胞(人乳腺癌、人小细胞肺癌、人胃癌、人结肠癌、人神经胶质癌、人黑色素瘤、人宫颈癌、人肝癌、早幼粒白血病、肉瘤s-180、肝癌腹水型、小鼠宫颈癌-14及艾氏腹水癌等)生长与增殖,诱导肿瘤细胞分化、凋亡,抑制肿瘤新生血管生成、抑制肿瘤的浸润和转移、增强机体免疫力和降低化疗药物毒副作用等抗肿瘤活性。

细胞毒实验

实验目的:

通过体外培养人肺癌细胞a549,人胃癌细胞mgc-803,人胃癌细胞sgc-7901,人乳腺癌细胞mcf-7,人前列腺癌细胞pc-3,卵巢上皮细胞iose144,采用srb法检测细胞增殖活性,筛选受试化合物的体外抗肿瘤活性。

实验材料:

实验方法:

1.受试药物的配制:准确称取受试样品各2mg,用dmso配置成10mm,100μm的母液,用相应培养基配制成不同的浓度,0.22μm滤膜过滤备用。

2.细胞增殖抑制实验:取对数生长期细胞,调整密度为5×104加入不同浓度含药培养基100μl,对照组每孔加培养基100μl,对照组与药物组均设3个复孔,另设空白对照组,不加细胞只加培养基的作为对照组调零。将96孔板置5%co2培养箱(37℃)培养48h,加入0.04%srb20μl,继续培养4h后,弃上清,加入dmso150μl,振荡溶解10min,酶标仪于515nm处测定od值。

按公式计算抑制率,计算三次平行试验的ic50平均值,结果参见表1。

抑制率(%)=[(1-用药组平均od值/对照组平均od值)]×100%。

表1:化合物的细胞毒性

由表1中数据可知,本发明四环三萜衍生物对所测肿瘤细胞系均有不同程度的抑制细胞增长作用,抑制作用强于母体化合物。且对iose144无细胞毒活性。其中化合物17对所测肿瘤细胞系的活性最优(ic50=1.07±0.05μm至6.51±0.3μm),显著提升丙氨酸的活性,且显著优于对照丝裂霉素。

实施例25

将实施例1~实施例23分别进行阻滞和细胞凋亡,现选取最优实施例17进行详细说明。针对实施例17进行周期阻滞实验。

从图1~图4中,周期阻滞评估表明,相比对照组,经化合物17给药的a549细胞中,处于s期的细胞数目显著增多,提示化合物17能够诱导a549细胞s期阻滞。

实施例26

进行细胞凋亡实验。

如图5~图9所示,以及图10、图11,细胞凋亡实验结果显示,同母体化合物ad-2相比,实施例17对肺癌a549细胞具有显著的促进凋亡作用。
