Description

一种透明质酸-茶皂素及其制备方法和抗肿瘤作用
技术领域
本发明涉及医药领域,特别是涉及一种透明质酸-茶皂素及其制备方法和抗肿瘤作用。
背景技术
油茶树是我国南方特有的经济树种,在赣南地区种植面积广、资源多。茶皂素(teasaponin,TS)广泛存在于山茶科植物的根、茎、叶、花、果,籽之中,其作为油茶树中的天然绿色提取物,具有杀菌、抗氧化、抗肿瘤和抗炎症等多种生物活性。近年研究发现,TS能够通过阻滞细胞周期中的S期,抑制肿瘤血管生成等方式,诱导肿瘤细胞产生自噬、凋亡,具有一定的抗肿瘤能力。但是,过量的茶皂素会通过破坏细胞膜的通透性,导致细胞质外渗,最终引发人红细胞溶血。而且当药物临床前期研究中如果剂量超过50μM,则认为无体内抗肿瘤作用。因此,如何提高TS的抗肿瘤药学,减少使用量,是其在抗肿瘤研究中亟需解决的问题。
CD44是哺乳动物细胞表面普遍存在的跨膜糖蛋白,在多种实体瘤细胞表面过量表达,在正常细胞不表达或微量表达。透明质酸(hyaluronic acid,HA)是细胞外基质的主要成分,主要通过与CD44受体特异性结合,实现靶向性抗肿瘤作用。经HA修饰后的药物具有体内滞留时间延长、疗效增强、不良反应降低等特点。
发明内容
本发明的第一个目的是提供一种抗肿瘤效果好的透明质酸-茶皂素。
本发明的透明质酸-茶皂素或其药用盐,其结构如式1所示:
Figure BDA0003632245480000021
本发明的第二个目的是提供一种透明质酸-茶皂素的合成方法,其合成路线如下所示:
Figure BDA0003632245480000022
其是将透明质酸和茶皂素在N-(3-二甲氨基丙基)-N′-乙基碳二亚胺盐酸盐(EDC)的存在下,通过酯化反应合成透明质酸-茶皂素。
本发明的第三个目的是提供透明质酸-茶皂素或其药用盐在制备抗肿瘤药物中的应用。
本发明的第四个目的是提供一种抗肿瘤药物,其含有透明质酸-茶皂素或其药用盐作为活性成分。
优选,所述的抗肿瘤药物是抗人肝癌、人结直肠癌、人肺癌或人前列腺癌的药物。
本发明基于赣南地区特色产业油茶提取物茶皂素TS,首次将TS通过化学合成的方法接枝HA,合成了HA-TS。利用HA的生物特性,提高了TS的靶向性和生物利用度,提高其抗肿瘤效果,对基于TS的抗肿瘤药物研发具有重大的理论和现实意义,并具有良好的油茶产业开发应用价值。

具体实施方式
以下实施例是对本发明的进一步说明,而不是对本发明的限制。
实施例1:
1、本发明的透明质酸-茶皂素的制备与鉴定
1.1HA-TS的合成:在N-(3-二甲氨基丙基)-N′-乙基碳二亚胺盐酸盐(EDC)的存在下,通过酯化反应合成HA-TS(图1、2)。首先称取500mg 1.32mmol的HA(透明质酸)置于圆底烧瓶中,用6ml蒸馏水溶解;后将304mg 1.584mmol的EDC用1ml蒸馏水溶解,并将溶解的EDC逐滴加入HA中。冰浴搅拌1h后,再将2.78g 1.98mmol的TS(茶皂素)完全溶解于4ml H2O并加入上述反应体系中,常温搅拌24h,将所得溶液转移至透析袋中(截留分子量3500)透析8h,冷冻干燥即得。
1.2HA-TS的鉴定:利用核磁共振氢谱对合成的HA-TS进行鉴定,确定分子结构(图3-5)。
由此确定合成的HA-TS的结构式如下所示:
Figure BDA0003632245480000041
2、本发明的透明质酸-茶皂素的抗肿瘤作用
选取表达HA受体的细胞株:人肝癌HepG-2细胞、人结直肠癌HCT-116细胞、人肺癌A549细胞、人前列腺癌C4-2、LNCaP和PC-3细胞,对上述细胞进行体外培养。利用CellCounting Kit-8(CCK-8)法,研究HA-TS对多种肿瘤细胞的作用。
实验方案:将上述细胞以1×104个/孔的数量种于96孔板,加DMEM培养液,置于含5%CO2的37℃培养箱培养,待细胞贴壁后,每孔加入DMEM培养液倍比稀释的100μL不同浓度的HA-TS,对照组加入等体积的DMEM培养液,每组不少于3复孔。HA-TS处理24h或48h后,每孔加入10μL CCK-8溶液,继续孵育30min后,多功能酶标仪检测450nm处的吸光值。通过与对照组相比,计算肿瘤细胞增殖情况。利用Graphpad8.3.4软件处理数据,绘制柱状图,并采用非线性拟合法计算半数抑制率(half maximal inhibitory concentration,IC50)值及95%的可信区间(95%confidence interval,95%CI)。
结果显示,HA-TS对体外培养的人肝癌HepG-2细胞、人结直肠癌HCT-116细胞、人肺癌A549细胞、人前列腺癌C4-2、LNCaP和PC-3细胞均具有抑制作用(图6-11、表1)。
表1HA-TS对体外培养肿瘤细胞抑制作用的IC50(CCK8法)
Figure BDA0003632245480000051
根据美国国家癌症研究中心(National Cancer Institute)划分标准:IC50值小于1μM为强效抑制剂,1μM<IC50<10μM为中效抑制剂,10μM<IC50<50μM为弱效抑制剂,IC50值大于50μM为体外无有效抑制作用。HA-TS可能为HCT-116细胞、C4-2细胞和LNCaP细胞的中效抑制剂,可能为HepG-2细胞和A549细胞的弱中效抑制剂,可能为PC-3细胞的弱效抑制剂。
本发明公开了HA-TS的合成方法,并明确了其在体外的抗肿瘤作用,所合成的HA-TS不仅在体外实验中表现出较好的抗肿瘤效果,而且茶皂素改造后其对肝癌细胞株HepG-2的作用发生了根本性的变化:即由无抑制作用转变为强抑制作用。因此,HA-TS赋予了TS新的抗肿瘤特性,具有良好的推广应用前景。
