Abstract
本发明公开了含有1,2,3‑三氮唑基团的粉背蕨酸衍生物及其制备方法和应用,属于医药化工领域,本发明以粉背蕨酸为底物,首先在缩合剂作用下,与炔丙胺反应得到中间体N‑炔丙基粉背蕨酰胺,之后与叠氮化合物发生点击反应合成一系列含有1,2,3‑三氮唑的粉背蕨酸衍生物。对所得的粉背蕨酸衍生物,测试了它们对五种常见癌细胞系的细胞毒性。结果表明,大部分化合物对五种癌细胞系均表现出明显的抗增殖活性,同时有部分化合物在10μM浓度下,即可对5种癌细胞系均可达到半数以上的抑制率。本发明合成过程简易快捷,合成效率高,是继胺化之后对粉背蕨酸结构改造合成新化合物的另一种有效途径,合成制备得到的粉背蕨酸衍生物有望应用于抗肿瘤药物领域。
Description
技术领域
本发明属于医药化工领域,涉及一种化合物的制备和应用,具体地,涉及含有1,2,3-三氮唑基团的粉背蕨酸衍生物及其制备方法和应用。
背景技术
银粉背蕨[Aleuritopteris argentea(Gmel.)Fée)]是原中国蕨科粉背蕨属植物,现归并到凤尾蕨科粉背蕨属。其背部常覆盖一层银白色粉状物,因之得名。其干燥茎状如铜丝,俗称铜丝草,又因其能活血调经、治疗月经不调,闭经腹痛等症状,又称为通经草,在我国蒙古族、藏族等少数民族中作为民间药材使用。
银粉背蕨含有多种天然次级代谢产物,比如黄酮、绿原酸、多糖及萜类化合物。上田博之等于1962年首次从中分离得到了一种半日花烷型二萜类化合物,即粉背蕨酸,并通过化学讲解的方法确定了其基本构型(Ageta,H等.Proc.Symp.Nat.Org.Compd.1962,6,136)。哈婧等还从银粉背蕨分离了两个新的二萜(Li,J.-C.等.Phytochem.Lett.2017,20,22)。粉背蕨酸及其类似物还从古巴香胶树的精油,非洲驼足帽柱豆等植物中分离得到(Afolayan,M.等.Med.Chem.Res.2018,27,2325-2330)。
前期科学家对于粉背蕨酸的药理研究尚少。公开号为109810017A的中国发明专利公开了一种含有粉背蕨酸的通经草提取物在制备抗癌药物中的应用。该提取物能显著地抑制小鼠肉瘤血管形成,并抑制瘤体生长。发明人前期研究发现,对粉背蕨酸的15-位羧基进行改造,合成的粉背蕨酸酰胺类衍生物,能够显著地提高其抗癌活性。合成的新化合物能刺激细胞色素c从线粒体中释放,切割并激活caspase-3和caspase-9,并导致PARP-1被切割,最终通过线粒体介导的内源性凋亡通路引起HeLa细胞的凋亡。
1,2,3-三氮唑作为最重要的杂环化合物之一,可以与不同的生物靶点形成疏水作用、氢键、范德华力等多种非共价相互作用。化合物经过1,2,3-三氮唑衍生之后可产生具有更好生物活性性能的杂化分子,具有1,2,3-三氮唑基团的化合物具有多种生物活性,例如抗菌、抗疟疾、抗真菌、抗病毒、抗结核和抗肿瘤活性等等。很多天然产物,经过与1,2,3-三氮唑基团的拼合,都能获得更好的生物活性。但是尚没有对粉背蕨酸和1,2,3-三氮唑基团的杂合研究。考虑到1,2,3-三氮唑基团也可看作是酰胺键的生物电子等排体,而粉背蕨酸的酰胺衍生物又有良好抗肿瘤活性,本发明对粉背蕨酸进行结构修饰,引入1,2,3-三氮唑药效团,以期发现新的抗癌活性分子。
点击反应是制备1,2,3-三氮唑化合物的重要手段之一。铜(I)催化叠氮化合物和末端炔烃形成1,2,3-三氮唑的反应具有高度的可靠性、完全的特异性以及良好的生物相容性,可以创建用于药理活性筛选的新化合物库。基于此,我们采用点击反应条件,以硫酸铜和抗坏血酸钠相互作用之后形成的铜(I)作为催化剂,通过点击反应得到一系列粉背蕨酸的1,2,3-三氮唑衍生物。
发明内容
本发明的目的在于克服现有技术的缺陷,提供一种含有1,2,3-三氮唑基团的粉背蕨酸衍生物及其制备方法和应用,本发明以从银粉背蕨中分离的粉背蕨酸为底物,首先合成中间体N-烯丙基粉背蕨酰胺,然后在铜离子的催化条件下,经由点击反应与叠氮化合物相互作用生成一系列目标产物。经过产物的分离及结构鉴定后,对目标产物进行抗肿瘤活性的研究。
本发明的目的可以通过以下技术方案实现:

将合成的24个衍生物3a-3x进行抗肿瘤活性研究。
2.抗肿瘤活性实验步骤
(1)在光学显微镜中观察细胞状态,选择对数生长期细胞株,同细胞传代方法,先用无菌PBS清洗一次,再将细胞用胰酶消化几分钟(根据细胞消化变圆时间而定),离心收集细胞,1mL DMEM完全培养基重悬,充分吹打,配成单细胞悬液。在96孔板中,每孔加入100μL细胞悬液,计数后,铺板使待测细胞调密度至1000-10000个/孔(边缘孔用无菌PBS填充)。将96孔板放入37℃、5%CO2细胞培养箱中培养。
(2)培养约24h后,细胞贴壁完全,确定药物加药浓度梯度,一般为5-6个,每组设3个复孔,单药共测三组。
(3)5%CO2,37℃孵育72小时,倒置显微镜下观察。
(4)每孔加入20μL浓度为5mg/mL的MTT溶液,37℃、5%CO2细胞培养箱中孵育2h。
(5)2h后,因活细胞线粒体中的琥珀酸脱氢酶能使外源性MTT还原为水不溶性的蓝紫色结晶甲瓒并沉积在细胞中,而死细胞无此功能。因此,小心弃去孔中原有培养基,每孔加入100μL三联液,置于5%CO2,37℃培养箱中过夜,使结晶物充分溶解。使用酶联免疫检测仪在570nm条件下,测量各孔的吸光值。
(6)同时设置调零孔(培养基、MTT、二甲基亚砜),对照孔(细胞、相同浓度的药物溶解介质、培养液、MTT、二甲基亚砜)。
各化合物对人非小细胞肺癌细胞A549、人肺癌细胞PC-9、人乳腺癌细胞MCF-7、人前列腺癌细胞PC-3、人宫颈癌细胞HeLa以及人正常肝细胞HL-7702的IC50如表1所示。
表1.化合物(3a-3x)抗肿瘤活性结果
本发明以粉背蕨酸为底物,首先与丙炔胺缩合得到中间产物N-炔丙基粉背蕨酰胺,之后在铜(Ⅰ)离子催化条件下,与叠氮化合物发生点击反应,得到一系列粉背蕨酸的1,2,3-三氮唑衍生产物,并对这些化合物通过理化性质和多种波谱方法进行了结构鉴定。在抗肿瘤活性筛选中,以顺铂为阳性对照,采用MTT法测定了其对人非小细胞肺癌细胞A549、人肺癌细胞PC-9、人乳腺癌细胞MCF-7、人前列腺癌细胞PC-3、人宫颈癌细胞HeLa以及人正常肝细胞HL-7702细胞系的细胞毒性。
在抗肿瘤活性筛选中,大部分的化合物均表现出明显的抗肿瘤活性,其中部分化合物具有较为明显的抗肿瘤效果,例如化合物3b、3n、3o、3q、3r、3s以及3u,对于以上5种不同人癌细胞系的大多数癌细胞,IC50值均为10μM左右。这当中,化合物3n对A549细胞和PC-9细胞的IC50分别为4.0μM和7.23μM;化合物3s对MCF-7细胞、PC-3细胞和HeLa细胞的IC50值分别为2.12μM、5.74μM、7.58μM,且与其他5个化合物相比,这两种化合物对人正常肝细胞(HL-7702)具有相对较低的细胞毒性,在人正常肝细胞和癌细胞之间具备较高的选择性,因此3n及3s为抗肿瘤效果较好的两个化合物。
