Description
技术领域
本发明涉及一例用于检测体内硝基还原酶有机染料分子的设计、合成及其在生物分析中的应用,尤其是对硝基还原酶(NTR)与还原型辅酶烟酰胺腺嘌呤二核苷酸(NADH)具有双响应的有机荧光染料。
背景技术
细胞缺氧现象是由于细胞内氧气供应不足而引起的,缺氧状态下会引发一系列疾病,如心脏局部缺血、中风和炎症等。此外,缺氧状态也是恶性肿瘤生长过程中普遍存在的现象。恶性肿瘤不易治愈是肿瘤细胞的易转移性所造成的,同时会增加对化疗、放疗的抗性,从而使治疗效果降低。因此,探究细胞缺氧,发展细胞缺氧状态的检测办法,对于疾病诊断、临床治疗及增强机体适应能力等研究具有及其重要的意义。肿瘤细胞由于恶性增殖会导致细胞缺氧,而缺氧又会导致细胞内硝基还原酶(NTR)活性升高。在缺氧状态下,以还原型烟酰胺腺嘌呤二核苷酸(NADH)为电子供体,细胞内的NTR可将含硝基的芳香族化合物还原为响应羟胺或者氨基化合物。
烟酰胺腺嘌呤二核苷酸(NADH)是细胞内许多脱氢酶的辅酶,在细胞内以NADH和NAD+两种形式存在。主要形式是氧化型的NAD+在热力学上是更稳定的。近些年的研究表明,NADH参与了许多生物学过程,在细胞能量代谢、抗氧化、基因表达、细胞凋亡及癌变等生物过程中有着极其重要的作用。正常生理状态下及不同的病理情况下,NAD+/NADH的含量是不同的。通过检测细胞内NAD+/NADH的变化可以对生物体内的生理过程进行评估。
荧光成像是一种极具前景的检测活体系统中生物活性分子的方法。荧光成像是一种高灵敏度、高选择性能快速响应和高效分析生物体的有利工具,可用于追踪体内目标状态、变化和活动状况,从而促进细胞生物学的进展。小分子荧光探针具有良好的稳定性、灵敏度和选择性,用于荧光成像还可以保持生物样品完整性。由于其优良的特性,被广泛应用与生物检测和成像中。近年已经开发了许多用于NTR和NADH检测的小分子荧光探针,但均不能实现NTR与NADH双线检测。
发明内容
本发明的目的在于提供一类对于硝基还原酶(NTR)与辅酶烟酰胺腺嘌呤二核苷酸(NADH)具有双响应荧光染料分子,其具有通式I的结构:
通式I中:
所述的M是N或P;
所述的R1和R2各独立选自:
其中的x选自0-8的整数;
所述的L选自:
其中的n选自于0-6的整数。
另一方面,本发明提供上述荧光染料的制备方法,包括如下步骤:
在催化剂存在条件下,化合物a和b按照摩尔比1:1-1:10反应,制备通式I的化合物;
反应温度为0-200℃,反应时间为1-32小时,反应溶剂选自乙醇、冰醋酸、乙二醇单甲醚、甲醇、二氯甲烷、丙酮、丙三醇、乙酸乙酯、N-N-二甲基甲酰胺或其混合物;催化剂选自哌嗪、哌啶、氢氧化钾、氢氧化钠、吡啶、甲醇钠、甲醇-氢氧化钾、碳酸钾、三乙胺和4-二甲氨基吡啶。催化剂与反应物摩尔比为1:0.05-1:0.2。
本发明所述的荧光染料具有高的灵敏度和分辨率、低/无毒性、合适的水溶性、高选择性识别以及特殊的光学性质等特点。其光谱范围与生物样品的光谱范围有足够大的差异,可以避免生物自发荧光的产生。
除此之外,本发明所述的荧光染料具有对生物体内硝基还原酶(NTR)与烟酰胺腺嘌呤二核苷酸(NADH)具有双线响应的特性。因此,本发明另一方面的目的还在于提供本发明所述的荧光染料在制备硝基还原酶(NTR)与烟酰胺腺嘌呤二核苷酸(NADH)检测试剂中的应用。特别是具有NTR与NADH双线检测功能的检测试剂。区别于目前市面上存在的具有单一检测功能的硝基还原酶(NTR)或者烟酰胺腺嘌呤二核苷酸(NADH)检测试剂,本发明的双响应荧光染料分子可以用于制备对其具有双线检测功能的试剂,在生物学检测方面具有良好的应用前景。
