Description
技术领域
本发明属于粉背蕨酸衍生物技术领域,涉及一种新型粉背蕨酸酰胺衍生物及其合成与应用。
背景技术
癌症是当今世界直接危害人类生命的一种最常见、最严重的疾病,目前抗癌药物多为化学合成药,多半会对人体健康细胞产生毒副作用,因此寻找无毒害的、有效的抗癌药物和方法已成为国内外医学研究的热点。近年来从植物中分离并鉴定出大量具有强生物活性的天然产物,其中很大部分具有优良的抗癌活性,且毒副作用较小。因此从植物中分离、鉴定、修饰并筛选抗癌药物已成为治疗癌症的一条有效途径。
粉背蕨酸是从中国蕨科植物银粉背蕨(Aleuritopteris argentea(Gmél.)Fée)中分离得到的一种半日花烷型二萜类化合物,研究表明其具有多种生物活性,如:抗菌、抗寄生虫、抗病毒等。(Trindade R D,Silva J D,Setzer W.Copaiferaof the neotropics:areview of the phytochemistry and pharmacology.International Journal ofMolecular Sciences,2018,19(5):1511.)也有研究者发现粉背蕨酸对人胃癌和XG恶性胶质瘤细胞有一定的抑制作用。(Vargas,F.D.S.;de Almeida,P.D.O.;Aranha,E.S.P.;Boleti,A.P.D.A.;Newton,P.;de Vasconcellos,M.C.;Veiga Junior,V.F.;Lima,E.S.Biological activities and cytotoxicity of diterpenes from Copaiferaspp.oleoresins.Molecules,2015,20,6194–6210.)

实施例19:
将粉背蕨酸及其上述实施例1-实施例18制备的18个芳香酰胺衍生物进行抗癌活性筛选。
抗肿瘤活性实验步骤
(1)收集对数生长期细胞,调整细胞悬液浓度,每孔加入100μL细胞悬液,铺板使待测细胞调密度至1000-10000孔,(边缘孔用无菌PBS填充)。
(2)5%CO2,37℃孵育,原则上,细胞贴壁后即可加药,2~16小时左右,常在前一天下午铺板,次日上午加药。加入对应浓度梯度的药物,一般3-5个梯度,每孔10μL,设3-5个复孔。
(3)加药完成后,5%CO2,37℃孵育72小时,倒置显微镜下观察。
(4)每孔加入20μL MTT溶液(5mg/ml,即0.5%MTT),继续培养4h。若药物与MTT能够反应,可先离心后弃去培养液,小心用PBS冲2-3遍后,再加入含MTT的培养液。
(5)每孔加入100μL三联液,置5%CO2,37℃培养过夜,使甲瓒结晶物充分溶解。在酶联免疫检测仪OD 570nm处测量各孔的吸光值。
(6)96孔板需同时设置调零孔(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)。通过吸光值计算每种药物的IC50。
各化合物对非小细胞肺癌A549,乳腺癌MCF-7,前列腺癌PC-3以及宫颈癌Hela,以及正常人肝细胞HL-7702的IC50如下表1。
表1.化合物ZFB-ZFB18抗肿瘤活性结果
可见,上述各实施例中,通过以粉背蕨酸为底物,在缩合剂作用下,与各种胺类化合物反应,得到一系列粉背蕨酸芳香酰胺类衍生物,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。在抗癌活性筛选中,以顺铂为阳性对照,采用MTT法测定了其对前列腺癌PC-3、乳腺癌MCF-7、前列腺癌PC-3、非小细胞肺癌A549、宫颈癌Hela以及正常人肝细胞的抑制作用。
抗肿瘤结果显示大部分的化合物均表现出明显的抗肿瘤活性,ZFB-4、ZFB-6、ZFB-12和ZFB-16效果较好,对4种不同人癌细胞系,包括前列腺癌PC-3、乳腺癌MCF-7、前列腺癌PC-3、非小细胞肺癌A549、宫颈癌Hela的IC50均为10μM左右,其中化合物ZFB-12对MCF-7细胞的IC50为5.79μM。同时这些化合物对正常肝细胞HL-7702表现出较低的毒性。这些结果显示,这类新型粉背蕨酸酰胺衍生物有望应用于抗肿瘤药物领域。
上述的对实施例的描述是为便于该技术领域的普通技术人员能理解和使用发明。熟悉本领域技术的人员显然可以容易地对这些实施例做出各种修改,并把在此说明的一般原理应用到其他实施例中而不必经过创造性的劳动。因此,本发明不限于上述实施例,本领域技术人员根据本发明的揭示,不脱离本发明范畴所做出的改进和修改都应该在本发明的保护范围之内。
