技术领域:
本发明涉及有机合成、光学材料和药物化学领域,使用了较简单的原料和方法一步合成目标产物。
背景技术:
西弗碱是一种结构比较特殊的化合物,根据引入基团的不同可以合成不同种类的西弗碱;西弗碱在医学、催化、分析化学、腐蚀以及光致变色等领域都有重要应用,例如,在医学领域,西弗碱具有抑菌、杀菌、抗肿瘤、抗病毒的生物活性;在光学材料领域,由于其富电子和刚性平面的特点,使其具有良好的荧光性能及非线性光学性质。
联苯乙酮腙类西弗碱报道较少,但是该类化合物具有较大的共轭体系,使其更容易在光学材料领域产生特殊的性质;在药物设计领域,联苯环体系稳定了药物分子的芳香疏水相互作用,因此常被用于药物分子的构建。
发明内容
本发明的内容是合成了一种联苯乙酮腙-4-吲哚甲醛西弗碱化合物,该化合物外观呈棕黄色粒状微晶,熔点287.7-288.0℃,分子式C23H19N3,化学名为:4-((E)-((E)-(1-联苯-4-基)亚乙基)-肼叉)-甲基-1-H吲哚,[英文系统命名为:4-((E)-((E)-(1-(biphenyl-4-yl)ethylidene)-hydrazono)methyl)-1H-indole),缩写为4-BEHI;结构如下。
1、结构鉴定。
元素分析表明,其C、H、N的百分含量分别为81.86%、5.65%和12.46%(基于分子式C23H19N3的理论值分别为81.87%、5.68%和12.45%),有关的1HNMR谱见附图1。
2、合成方法。
该化合物合成方法上的特征在于:以联苯乙酮腙和4-吲哚甲醛为原料,采用溶液合成或固相合成法。步骤如下:
1)将联苯乙酮腙和4-吲哚甲醛分别溶于合适的有机溶剂中,然后按一定的摩尔比混合,在一定的温度下搅拌反应一定时间;也可以不用有机溶剂,直接混合两种反应物,研磨反应。
2)液相反应时,将得到的溶液采用一定的方法除去大部分溶剂,可得到粉末或结晶状物,即为目标产物;固相反应时,研磨一定时间可得目标产物。
3)目标产物可以在合适的有机溶剂中重结晶以纯化产品。
优选的,上述反应溶剂或重结晶用有机溶剂选自:甲醇、乙酸乙酯、二氯甲烷、乙醇、乙腈、丙酮、氯仿、四氢呋喃。
优选的,联苯乙酮腙和4-吲哚甲醛的反应摩尔比为1:4至4:1。
优选的,所述反应温度为室温至加热回流。
优选的,所述反应时间为:0.5-12小时。
优选的,所述除去溶剂的方法为自然挥发或常/减压蒸馏。
本发明的有益效果是:能够以比较简单的步骤和反应物一步合成比较复杂的功能分子材料,并且分离方法简单。
3、紫外和荧光性质。
在10-6mol/L乙醇溶液中测试本化合物的紫外光谱,发现其在207nm,296nm和360nm处有三个主要的紫外吸收峰,紫外光谱图见附图2。
在10-5mol/L乙醇溶液中,测试本化合物的荧光性质,发现其在450-550nm范围内有强的荧光发射,荧光光谱见附图3。
4、体外抗肿瘤活性:
将处于对数期生长的乳腺癌细胞4T1用0.25%胰酶消化细胞,使其成为单细胞,用含10%胎牛血清的F12K培养液制成浓度为1.25×107个/L的单细胞悬液,将细胞接种于96孔培养板中,每孔200μL(每孔2.5×103个细胞)。将96孔细胞培养板置于CO2培养箱中,在37℃,5%CO2条件下,培养48h。
当孔内细胞长满(90%满即可)时,按实验分组加入不同剂量的本西弗碱溶液(200μL/孔),使待测化合物的终浓度分别为5μM、10μM、30μM、50μM、100μM,每组设3个复孔,培养96h。
各个孔中分别加入20μL浓度为0.5g/L的MTT,继续培养4h,使MTT还原为甲瓒(Formazan)。吸出全部上清液后,每孔加入200μL的DMSO,震摇15min,使甲瓒充分溶解后,运用酶联免疫检测仪测定490nm处的吸光度(OD值)。然后按照下式进行计算:
细胞抑制率%=(对照组OD值-实验组OD值)/对照组OD值×100%
测试结果表明,该西弗碱对乳腺癌细胞4T1的IC50(药物的半数抑制浓度)为33.5μM,这表明该化合物对该癌细胞具有较好的抑制效果。
具体实施方式
为了更好的理解本发明内容,下面通过两个具体实施例进一步说明本发明的技术方案:
