Description
技术领域
本发明属于有机合成领域,具体涉及一种3-芳基吲哚嗪乙酸酯衍生物及其制备方法和应用。
背景技术
如今,吲哚嗪已成为一类重要的含氮杂环结构,其普遍存在于天然产物合成和医药领域。吲哚嗪类衍生物体现出抗菌活性、雌激素受体结合活性、抗结核性、磷酸酶抑制活性和抗癌活性。并已经作为抗糖尿病药、抗炎药、抗组胺剂和抗乙酰胆碱剂、抗氧化剂、磷酸二酯酶抑制剂、PDE5A抑制剂、L型钙通道阻滞剂和白三烯的合成抑制剂得到了广泛应用(V.Sharma and V.Kumar,Med.Chem.Res.2014,23,3593.)。
因此,许多关于合成功能化吲哚嗪的方法已大量报道,关于修饰吲哚嗪核心及其衍生化,在过去这些年里吲哚嗪的C-3芳基化方法已经成熟了很多。
2004年,Gevorgyan课题组报道了第一篇关于钯催化下的使用芳基溴化物的C-3芳基化反应(Park C H,Ryabova V,Gevorgyan,V,et al.Palladium-Catalyzed Arylation and Heteroarylation of Indolizines.Org.Lett,2004(6):1159~1162)。该反应需在钯催化条件下,而且在NMP溶剂环境中,收益较好,产物为吲哚嗪的五元环上的C-3苯取代。具体反应方程式如式1-1所示。
2009年,Fagnou课题组报道了类似的催化体系(Liegault B,Lapointe D,Caron L,Vlassova A.Fagnou K.Establishment of Broadly ApplicableReaction Conditions for the Palladium-Catalyzed Direct Arylation ofHeteroatom-Containing Aromatic Compounds J.Org.Chem,2009(74):1826-1834)。该反应所用的芳基源为对溴甲苯,并在催化量的醋酸钯及PCy3·HBF4及1.5当量的碳酸钾存在条件下,于100℃下反应4小时,便可得到收益良好的吲哚嗪C-3芳化产物。具体反应方程式如式1-2所示。
在钯催化条件下,以芳基氯化物作为基底相对而言更加具有挑战性,因为其化学反应性差以及芳基氯键难以用钯氧化。游劲松课题组应用芳基氯作为芳基化底物,成功地实现这一目标(Liu B,Wang Z,Wu N,Li M,YouJ,Lan J.Discovery of a Full-Color-Tunable Fluorescent Core Frameworkthrough Direct C-H(Hetero)arylation of N-Heterocycles[J]Chem.Eur.J,2012(18):1599~1603)。该反应所用的芳基源为芳基氯化物,并在催化量的醋酸钯及PCy3·HBF4配体存在条件下,于130℃下回流24小时,便可得到收益良好的吲哚嗪C-3芳化化合物。具体反应方程式如式1-3所示。
芳基硼酸衍生品被视为非常重要的试剂。2009年,You课题组报道了重要性进程(Xia J B,You S L.Synthesis of 3-Haloindolizines by Copper(II)Halide Mediated Direct Functionalization of Indolizines.Org.Lett,2009(11):1187~1190)。他采用C-3加氯作用和Suzuki-Miyarua交叉耦合,实现了用芳基硼酸的吲哚嗪C-3芳基化。该反应没有使用钯催化剂,而是以二价的卤代铜作为反应条件,在乙腈的溶剂环境中,于40℃或室温下反应,即可得到收益良好的吲哚嗪C-3芳化化合物。说明此反应具有低能耗高收益的优点。具体反应方程式如式1-4所示。
2014年5月,Huayou Hu课题组报道了采用芳基硼酸的吲哚嗪的直接芳基化反应(Hu H,Liu Y,Xu J,Kan Y,Wang C,Ji M.Palladium catalyzedoxidative Suzuki coupling reaction of indolizine at the 3-position using oxygengas as the only oxidant RSC Adv,2014(4):24389~24393)。该反应通过Pd(OAc)2/O2系统,使用吡啶甲酸作为配合物,以芳基硼酸作为芳基源,成功地实现了吲哚嗪的C-3芳基化。具体反应方程式如式1-5所示。
在2012年,我们课题组也报道了此类反应(Zhao B.Pd-Catalyzed C-3functionalization of indolizines via C–H bond cleavage Org.Biomol.Chem,2012(10):7108~7119)。该反应使用ArBF3K作为芳基源,在相应的催化剂和溶剂中,于90℃下反应12小时,便可得到收率良好的吲哚嗪C-3芳化产物。具体反应方程式如式1-6所示。
发明内容
本发明提供了一种3-芳基吲哚嗪乙酸酯衍生物及其制备方法和应用,该3-芳基吲哚嗪乙酸酯衍生物具有一定的细胞增殖抑制活性,具有作为抗癌药的潜力;该制备方法所用的原料稳定易得,并且反应条件温和,转化率高,副反应少。

式(Ⅰ)中,Ar为取代或者未取代的芳基;
所述芳基上的取代基选自C1~C4烷基、C1~C4烷氧基、卤素、硝基、三氟甲基或者烷酰基。
通过对本发明的3-芳基吲哚嗪乙酸酯衍生物进行活性测试,发现其对肿瘤细胞的抑制具有较好的抑制活性,具有较低的IC50值,具有作为抗癌药的潜力。
其中,表示
作为优选,所述的芳基为苯基或者萘基。
作为优选,所述的芳基上的取代基选自甲氧基、甲基、叔丁基、F、Cl、Br、-NO2、CF3或者甲酰基。

反应方程式如下:
近年来,芳基亚磺酸钠已广泛应用于有机化学、生物有机化学和药物化学中合成各种生物活性化合物的功能结构,成为了一类新颖且便宜易得的合成试剂。相对于易水解而释放HCl的芳基磺酰氯,芳基亚磺酸钠更稳定易处理,是构建C-C键的理想芳基来源。本发明通过采用二价钯催化剂/含氮配体/过氧化物体系,成功地实现了吲哚嗪乙酸酯的3位芳基化反应,具有重要的应用意义。
二价钯催化剂的种类会对反应效率产生很关键的影响,作为优选,所述的二价钯催化剂为Pd(OAc)2,此时,反应收率高。
影响反应效率的另外一个重要因素是含氮配体的种类,作为优选,所述的含氮配体为2,2’-联吡啶。
作为优选,所述的过氧化物为过氧化醋酸叔丁酯。
反应介质的选择也会对反应结果产生较大的影响,作为优选,所述的有机溶剂为乙腈。
作为优选,反应温度为90~100℃,反应时间为6~10小时。
本发明还提供了一种所述的3-芳基吲哚嗪乙酸酯衍生物在制备抗肿瘤药物中的应用。

抗增殖活性测试:
取刚刚长成完整单层的细胞一瓶(HCT116肠癌细胞),胰蛋白酶消化后收集细胞,用移液管吹打均匀,取两滴细胞悬液台盼蓝(Trypan Blue)染色,于显微镜下计数活细胞数目(死细胞数目不得超过5%),用完全培养液调整细胞数目至1×105个细胞/mL。于96孔细胞培养板中每孔加入100μL细胞悬液,将培养板置于CO2培养箱中培养12h,取出培养板后于每孔中加11μL含不同浓度被测样品的溶液,使得药物终浓度分别为40.0、20.0、10.0、5.0、1.0和0.1μg/mL,每个浓度设3个平行孔,另设3孔细胞不加被测药作正常对照孔。加完药后培养板于微孔板振荡器上振荡混匀,置于CO2培养箱中继续培养48h。取出培养板,每孔加入25μL 4mg/mL的MTT液,振荡混匀,继续培养6h。加入每孔100μL SDS裂解液(90mL三蒸水+10g SDS+5mL异丙醇+2mL浓盐酸)后培养12h。于酶标仪测定各孔光吸收(OD值),测定波长570nm,参考波长630nm。根据各孔OD值计算药物对细胞增殖的抑制率,检测结果见表4。
实验中通过酶标仪测定的各孔光吸收(OD值),计算药物对细胞增殖的抑制率:
抑制率=[1-(测试样品OD值-空白OD值)/(阴性对照OD值-空白OD值)]×100
按如下公式计算被测样品的IC50值(寇式法):
lgIC50=Xm-I[P-(3-Pm-Pn)/4]
其中Xm:设计的最大浓度的对数值;I:最大剂量比相临剂量的对数值;P:阳性反应率之和;Pm:最大阳性反应率;Pn最小阳性反应率。
