一种多信号比率型区分检测H2O2和H2S的荧光探针的设计、合 成及应用
技术领域
本发明涉及的是化学分析检测技术领域,具体涉及一种多信号比率型区分检测H2O2和H2S的荧光探针的制备方法以及该荧光探针在体外和活细胞内检测H2O2和H2S方面的应用。
背景技术
H2O2是其他活性氧的前体分子,在宿主防御,免疫应答和细胞信号传导中起着重要的作用。作为氧化应激的标志物,越来越多的研究表明,体内H2O2浓度的增加会诱导细胞蛋白的氧化损伤,导致神经退行性疾病,心血管疾病,癌症和阿尔兹海默症等。H2S作为体内的一种信号传递分子,在神经调节,细胞凋亡,抗炎症,抗氧化和抑制胰岛素信号传导等生理过程中起着广泛而重要的作用。研究发现,H2S通过提高细胞内谷胱甘肽的水平、调节抗氧化蛋白的高表达等途径,来保护细胞免受氧化应激的损伤。H2S本身具有的还原性也会直接清除H2O2等活性氧物质。H2S和H2O2在生理过程中有如此重要的作用,同时彼此互相影响,开发一种有效的检测方法是至关重要的,特别是对细胞内H2S和H2O2的浓度的监测,对生物学研究和临床诊断至关重要。
目前对H2S和H2O2的检测方法主要有比色法、电化学分析法、气相色谱法、滴定法、分光光度法和荧光法等。在这些方法中,荧光探针成像技术由于操作简单,灵敏度高,选择性好,实时成像等优点,特别是对组织的非破坏性而受到特别的关注。近年来开发了大量的荧光探针来检测H2S和H2O2,但他们都是独立的对H2S或H2O2进行选择性检测,还没有一个探针分子可以同时区分检测H2S和H2O2
发明内容
本发明目的之一是提供一种合成路线简单、反应条件温和、成本较低的荧光探针合成方法;目的之二是提供一种灵敏度高、选择性好,抗干扰能力强,斯托克斯位移大,发射波长在近红外,能够对体外或者活细胞内进行监测或者细胞成像的荧光探针。比率型荧光信号通过两个荧光信号的比值作为输出信号,探针分子本身的自校准能够克服诸如探针浓度、仪器灵敏度和环境因素带来的影响,提高荧光检测的准确性。通过探针与H2S和H2O2反应后获得不同组合的荧光信号来实现对H2S和H2O2的区分检测。
本发明解决问题采取的技术方案为,一种多信号比率型区分检测H2O2和H2S的荧光探针,其分子结构式如下:合成路线如下:
具体合成方法如下:将化合物(7-羟基-2-氧代-2H-色烯-4-基)甲基(E)-3-(7-((4- 叠氮苯基)氧基)-1,4-二乙基-1,2,3,4-四氢喹喔啉-6-基)-2-氰基丙烯酸酯和4-溴甲基苯硼酸频哪醇酯溶于丙酮,置于圆底烧瓶中,加入碳酸钾60℃搅拌回流反应。TLC监测反应完成后,停止反应,减压蒸馏除去溶剂,剩余物用柱层析分离纯化,二氯甲烷/乙酸乙酯(v:v =20:1,含1%三乙胺)作为洗脱剂。干燥得到红色固体
本发明的荧光探针测试方法如下,将探针分子溶于二甲基亚砜(DMSO)中,配制成1.0×10-3mol/L的溶液,室温下进行测试。并且对低浓度的H2S和H2O2可以进行定量检测,具体实施方法在实施实例中详细介绍。
本发明的荧光探针的作用机理如下,在探针分子中,探针本身发蓝色荧光,且有两个反应位点。当探针与H2S反应时,位点1的叠氮基被还原,随后醚键被切断,经过快速的分子内成环反应得到发蓝色荧光的HCB和发红色荧光的TQC。当探针TCAB与H2O2反应时,位点2的醚键被切断,释放出发蓝绿色荧光的化合物TCA,探针的荧光发生了从蓝光到蓝绿色的比值变化。通过探针TCAB与H2S和H2O2反应得到不同的荧光信号:H2S(蓝光+红光), H2O2(蓝光→蓝绿光),可以实现对H2S和H2O2的区分检测。随后,我们进一步研究了探针与两种响应物叠加响应的情况。当向探针TCAB与H2S响应后的溶液中继续加入H2O2时,前一步的产物HCB上的苯硼酸酯会继续被H2O2切断,从而释放出蓝绿色的荧光染料HC,同时之前得到的红光染料TQC不受影响。同样的,向探针TCAB与H2O2响应后的溶液中继续加入H2S时,TCA上的叠氮基会继续被H2S还原,醚键断裂,再经过快速的分子内成环反应得到发蓝绿色荧光的染料HC和发红色荧光的染料TQC。由此可见,探针TCAB可以实现对H2S和H2O2的连续检测。
探针分子的响应过程:
本发明的荧光探针探针TCAB与H2S和H2O2的荧光响应测试在HEPES缓冲液(20 mM,1.0mM CTAB,pH=7.4)中进行。探针本身在413nm处发蓝色荧光。当探针TCAB的溶液中加入H2O2时,413nm处的荧光下降,同时在486nm处有新的蓝绿色荧光生成(激发波长为325nm)。荧光滴定实验结果显示,随着H2O2浓度的增大,486nm处的荧光强度(F486nm) 与413nm处的荧光强度(F413nm)的比值显著增大,当H2O2浓度达到400μM时,F486nm/F413nm的值达到最大。并且F486nm/F413nm的值与H2O2的浓度在20-100μM范围内有很好的线性关系,线性相关系数为0.9968。另外,当探针TCAB与H2S响应时,反应液在413nm处的蓝色荧光增强(激发波长为325nm),同时在627nm处有新的红色荧光生成(激发波长为475 nm)。随着H2S浓度的增加,反应体系在413nm和627nm处的荧光强度逐渐增强,在350μM 的H2S加入时,荧光强度达到最大值。并且探针TCAB在413nm和627nm处的荧光强度与 H2S在浓度范围为0-150μM时具有很好的线性关系,线性相关系数分别为0.9905和0.9901。根据信噪比S/N=3,计算出探针TCAB对H2S和H2O2的检测限分别为0.058和0.044μM。随后,我们还测定了探针TCAB与H2S和H2O2响应前后的紫外光谱变化情况
本发明所述的探针分子合成路线简单,成本较低,对H2S和H2O2的选择性好、抗干扰能力强,斯托克位移大,该荧光探针在生物化学,环境科学等领域具有实际的应用价值。
