Description
技术领域
本发明涉及药物化学技术领域,是一类色胺酮1位或3位取代芳香硫醚衍生物的制备方法及其应用。
背景技术
癌症是一类异常细胞的病理性增殖,快速、不受控制,是世界范围内仅次于心血管疾病的第二大死因。在全球范围内,最新的建康统计结果显示,2020年的癌症发病率为1930万例新癌症病例,相比2018年的1810万例增加了6.2%。因此开发新型高效的抗肿瘤药物具有较好的前景。
细菌性病害是作物种植常见病害,但其严重危害农产品的质量和安全,构成全球性粮食安全问题。例如水稻白叶枯病菌(Xanthomonas oryzae pv.oryzae)是一类世界性的重要细菌病害。
色胺酮(Tryptanthrin)一类天然源生物碱,存在于产蓝植物中,如马蓝、菘蓝、蓼蓝(Strobilanthes cusia(Nees)Kuntze)等,在中药制成品青黛、板蓝根以及微生物发酵液和海洋微生物中均有所发现。色胺酮具有广泛的生物活性,主要有抗肿瘤、抗炎、抗菌、抗冠状病毒(NL63)和抗植物病毒(TMV)等方面活性。以色胺酮为先导化合物对其进行结构修饰,合成更高效的色胺酮类衍生物已成为国内外的研究热点
色胺酮类衍生物生物活性的研究进展如下:
2020年,Catanzaro等[Catanzaro,E.,Betari,N.,Arencibia,J.M.,Montanari,S.,Sissi,C.,Simone,A.D.,Vassura,I.,Santini,A.,Andrisano,V.,Tumiatti,V.,Vivo,M.D.,Krysko,D.V.,.Rocchi,M.B.,Fimognari,C.,Milelli,A.Targeting topoisomeraseII with trypthantrin derivatives:Discovery of7-((2-(dimethylamino)ethyl)amino)indolo[2,1-b]quinazoline-6,12-dione as an antiproliferative agent andto treat cancer.[J]Eur.J.Med.Chem.2020,202,112504-112513.]发现N,N二甲基乙胺取代的色胺酮衍生物对人类拓扑异构酶II(topoII)具有较强的抑制活性,其IC50为26.6±4.7mM,相比临床药物依托泊苷效果更强。由于增强了水溶性,对不同的肿瘤细胞系如急性白血病、结肠癌和乳腺癌抗增殖活性有了很大的提高,为抗癌药物的研发提供了一个具有广泛前景的先导化合物。
2020年,Hao等,[Hao,Y.N.,Guo,J.C.,Wang,Z.W.,Liu,Y.X.,Li,Y.Q.,Ma,D.J.,&Wang,Q.M.Discovery of Tryptanthrins as Novel Antiviral and Anti-Phytopathogenic-Fungus Agents.[J]J.Agric.Food Chem.2020,68,5586-5595]设计、合成了一系列色胺酮衍生物,对烟草花叶病毒(TMV)和植物性病原真菌进行了活性评价。发现色胺酮衍生物对TMV具有较高的抗病毒活性,大多数化合物抗TMV活性优于商品药利巴韦林。进一步的抗病毒机制研究发现,其通过分解20S外壳蛋白(CP)盘,进行抑制病毒组装。色胺酮作为新型抗病毒先导化合物,具有良好的抗病毒活性,具有较好应用开发价值。
2020年,Tsai等[Tsai,Y.C.,Lee,C.L.,Yen,H.R.,Chang,Y.S.,Lin,Y.P.,Su-HuaHuang,S.H.,&Lin,C.W.Antiviral Action of Tryptanthrin Isolated fromStrobilanthes cusia Leaf against Human Coronavirus NL63.[J]Biomolecules 2020,10,366-383]研究了植物菟丝子叶的甲醇提取物及其主要成分对人冠状病毒NL63(HCoV-NL63)的抗冠状病毒活性。发现所鉴定的6种成分中,色胺酮表现出较强的抗病毒活性,降低CPE和子代病毒的产生,对病毒产量的IC50值分别为1.52μM,而且对HCoV-NL63的作用与细胞类型无关。
硫醚类衍生物生物活性的研究进展如下:
2021年,El-Adl等[El-Adl,K.,El-Helbya,A.G.A.,Ayyada,R.R.,Mahdya,H.A.,Khalifaa,M.M.,Elnagara,H.A.,Mehanyc,A.B.M.,Metwalyd,A.M.,Elhendawye,M.A.,Radwanf,M.M.,ElSohly,M.A.,Eissa,I.H.Design,synthesis,and anti-proliferativeevaluation of new quinazolin-4(3H)-ones as potential VEGFR-2 inhibitors[J]BIOORGAN MED CHEM2021,29,115872]设计合成了一系列喹唑啉酮硫醚类衍生物,采用MTT法测定了肝癌细胞系(HepG-2,MCF-7和HCT-116细)的胞毒性,对所有细胞系均有一定的细胞毒活性,硫醚类取代基团能够促进细胞的毒性。并进一步评估了高活性化合物在体外抑制VEGFR-2的活性,体外抑制VEGFR-2的结果与细胞毒性数据一致。
2020年,Zan等[Zan,N.N.,Xie,D.D.,Li,M.,Donghao Jiang,and BaoanSong.Design,Synthesis,and Anti-ToCV Activity of Novel PyrimidineDerivativesBearing a Dithioacetal Moiety that Targets ToCV CoatProtein[J]J.Agric.FoodChem.2020,68,6280-6285]设计合成了一系列嘧啶硫醚类衍生物,采用番茄褪绿病毒外壳蛋白(ToCVCP)定向筛选方法,研究其对番茄褪绿病毒(ToCV)的抗病毒活性。发现了两个化合物均显著降低了本氏烟草ToCVCP基因的表达量,降低值分别为88%和83%,优于宁南霉素(65%)和先导化合物(73%)。因此,嘧啶硫醚类化合物在新型anti-ToCV药物的研究和开发中具有重要意义。

药理实施例1:
抗肿瘤活性测试。
通过MTT法测定化合物对A549(人非小细胞肺癌细胞)、PC-3(人前列腺癌细胞)、HepG2(人肝癌细胞)、K562(人慢性髓系白血病细胞)的抑制活性。
接种细胞步骤(适用于贴壁细胞、悬浮细胞)。
1.选取细胞:选择根据细胞生长曲线,选取对数生长期的细胞;
2.消化细胞:用0.25%胰蛋白酶消化单层培养细胞,用含10%FBS的DMEM/1640培养液配成单个细胞悬液;
3.细胞计数:用无水乙醇浸泡细胞计数板及血盖片;取10μL细胞悬液,滴加在血盖片边缘,使悬液充满血盖片和计数板之间,不能溢出血盖片也不能溢入两侧的玻璃槽内;在显微镜下观察计数板四角大方格中的细胞数。按照公式计算:(4个大格细胞数之和/4)×104×细胞液体积=3×104×所需总的细胞混液(一般密度为3×104,也可根据细胞性质不同换成其他密度计算);
4.显色,测值(适用于贴壁细胞)。加入MTT溶液(5mg/mL,10%MTT)20μL,孵育4h,终止培养;采用吸液的方式,将培养板内的溶液吸出;每孔加入150μLDMSO溶解甲臜颗粒,摇床震荡10min(150rpm/min),混匀,使用酶标仪,在490、570nm测定OD值。
抑制率=1-(加药组OD值-空白组OD值)/(阴性组OD值-空白组OD值)×100%;
空白对照孔:200μL培养液+150μL DMSO;
阴性对照孔:180μL细胞混悬液+20μL DMSO+20μLMTT+150μL DMSO;
加药孔:180μL细胞混悬液+不同浓度的药物20μL+20μLMTT+150μL DMSO;
本发明实施例辅以说明本发明的技术方案,但实施例的内容并不局限于此,目标化合物实验结果如表3所示。
表3目标化合物色胺酮1位或3位取代芳香硫醚衍生物对四种肿瘤细胞的抑制活性
表3色胺酮1位或3位取代芳香硫醚衍生物对四株肿瘤细胞的抑制活性
药理实施例2:
抗植物病原菌性测试。
采用浊度法测试色胺酮1位或3位取代芳香硫醚衍生物对植物病原菌细菌的抑制率,测试病原菌为水稻白叶枯病菌(Xoo)、柑橘溃疡病菌(Xac)和猕猴桃溃疡病菌(Psa)。空白对照为DMSO,阳性对照为叶枯唑和噻菌酮。恒温摇床在28℃和180rpm条件下,将Xoo、Xac和Psa病原菌接种于固体培养基(NA)中,使用时在28℃/180rpm恒温摇床中振荡培养到对数生长期备用。将被测试化合物和阳性对照药配置不同浓度的含毒NB液体培养基,分别加入40μL生长至对数期的含植物病原菌的NB培养基液体,在28℃/180rpm恒温摇床中振荡,水稻白叶枯病菌培养约36小时,猕猴桃溃疡菌和柑橘溃疡菌培养约48小时,待摇床中对照组的OD值在生长对数期时,通过酶标仪在595nm处分别测定空白对照组、阳性对照药和化合物OD值。
校正OD值和抑制率的计算公式如下:
校正OD值=含菌培养基OD值-无菌培养基OD值。
抑制率%=[(校正后对照培养基菌液OD值-校正含毒培养基OD值)/校正后对照培养基菌液OD值]×100。
本发明实施例辅以说明本发明的技术方案,但实施例的内容并不局限于此,部分目标化合物实验结果如表4所示。
表4色胺酮1位或3位取代芳香硫醚衍生物对三种植物病原菌细菌的抑制活性
测试结果为三次测定平均值。
上述实验活性数据表明,所测试的色胺酮1位或3位取代芳香硫醚衍生物对植物病原菌细菌均具有较好的抑制活性,该测试浓度下部分化合物的初筛抑制率优于阳性对照化合物叶枯唑和噻菌酮,可作为潜在的抑制植物细菌的候选先导化合物,具有较好的研究应用价值。
