Description
技术领域
本发明涉及染料探针制备领域,尤其涉及一种基于胸腺嘧啶的近红外方酸菁染料探针及其制备方法和应用。
背景技术
铁是维持人体正常生理机能或组织结构所必须的,是血红蛋白、肌球蛋白和细胞色素中的重要成分,是人体必需的微量元素之一。铁的缺乏会引起贫血,行为和智力方面的缺陷,即引起心理活动和智力发育的损害及行为改变,而且在以后补充铁后也难以恢复,然而,过多的摄入铁会在脑、肾、肝等部位聚集而引起病变。人们常说的补铁就是补充亚铁离子,因此,准确快速地检测各种食品、水中和生理样品中亚铁离子的含量非常重要。2006年Wayne E Jones设计了一种有机/无机杂化聚合化学传感器tmeda-PPETE来检测亚铁离子,该传感器选择性好,但是该探针的发射仍处在可见区λem=500nm,仍然没有达到近红外的激发发射,近红外的离子检测荧光效率高,可以避免蛋白质等生物大分子在紫外和近红外区的背景干扰,有利于活体细胞内离子的检测,因此必须在近红外处检测Fe2+,而目前并不存在能够在近红外处检测Fe2+的探针。
钴作为一种重要的微量元素,钴化合物在颜料、催化剂、制造业等方面都有重要的作用。钴是维生素B12的组成部分,因此,其生理功能的发挥离不开B12的支持。首先它需要合成维生素B12然后发挥造血功能,还可促进部分酶的合成。但是,它也有一些负面的效应,当钴离子浓度超标时会引起很多健康问题,会导致活细胞的基因突变。因此,人们对钴也产生了很大的关注,也有很多检测Co2+的可行的方法,比如,分光光度计法,ICP电感耦合等离子体质谱法等,但是成本高,耗时长,因此,荧光探针作为金属离子的识别受到很大关注。
方酸菁染料是由方酸与富电子芳基化合物或胺类化合物缩合生成的1,3_二取代衍生物。该类化合物的显著特征是在可见光至红外光区有狭窄而强的吸收带和较高的量子产率,这种光电特性主要来源于分子内强烈的供体-受体-供体(donor-acceptor-donor)间的电荷迀移作用。近年来,方酸菁类化合物以其优异的光学性能,即他能降低生物体内物质的自吸收和自发荧光的干扰,提高检测的选择性和灵敏度,降低对生命体的损伤。同时良好的光稳定性也备受青睐,成为功能性染料研究的热点之一。此外,方酸菁化合物对介质较为敏感,在不同溶剂中,其光学性能差别很大,并且与某些化合物作用后其自身颜色能够发生明显变化,是构筑化学传感器的理想材料。
发明内容

(4)称取等摩尔量的步骤(2)制得的产物和步骤(3)制得的蓝色产物,将步骤(3)制得的蓝色产物用二甲基甲酰胺(DMF)溶解于反应容器中,随后依次加入1-(3-二甲氨基丙基)-3-乙基碳二亚胺(EDCI)、1-羟基苯并三唑(HOBT)、N,N-二异丙基乙胺(DIPEA),室温搅拌1小时,将步骤(2)制得的产物加入到反应容器中,室温搅拌反应6-15小时,反应结束后,取出产物,旋蒸得到的蓝色固体,将二氯甲烷和甲醇以任意体积比混合,以其为洗脱剂,利用柱层析进行分离提纯,制得基于胸腺嘧啶的近红外方酸菁染料探针,反应过程如下,
作为优选,步骤(1)中(5-甲基-2,4-二氧代-3,4-二氢-2H-嘧啶-1-基)-乙酸和氯化亚砜的摩尔比为1~2:2~3。
作为优选,步骤(2)中白色固体和乙二胺的摩尔比为0.1~1:5~10。
作为优选,步骤(3)中6-羧基-2,3,3-三甲基-1-辛基-3H-吲哚盐与非对称吲哚方酸的摩尔比为0.5~1.5:0.5~1.5。
作为优选,步骤(4)中室温搅拌反应时间为12小时,室温搅拌反应时间为12小时制得的染料探针纯度最高。
一种基于胸腺嘧啶的近红外方酸菁染料探针的用途,所述染料探针用于识别Fe2+,具体操作步骤包括:
以二甲基亚砜为溶剂,把染料探针配制成浓度为10mM的染料探针溶液,在96孔板中依次加入2uL浓度为10mM的Fe2+溶液和2uL染料探针溶液,再加入196uL十二烷基磺酸钠溶液、丙酮水溶液、去离子水、乙酸水溶液或缓血酸铵-盐酸缓冲溶液,使每孔总体积为200uL,溶液由蓝色变成了橙黄色。
作为优选,所述的乙酸水溶液为乙酸和水体积比为4:6的乙酸水溶液。
一种基于胸腺嘧啶的近红外方酸菁染料探针的用途,所述染料探针用于识别Co2+,具体操作步骤包括:
以二甲基亚砜为溶剂,把染料探针配制成浓度为10mM的染料探针溶液,在96孔板中依次加入2uL浓度为10mM的Zn2+溶液和2uL染料探针溶液,再加入196uL乙醇、十二烷基磺酸钠溶液、丙酮水溶液、去离子水、乙酸水溶液或缓血酸铵-盐酸缓冲溶液,使每孔总体积为200uL,溶液由蓝色变成了无色。
本发明的有益效果是,本发明将1-(3-二甲氨基丙基)-3-乙基碳二亚胺(EDCI)和1-羟基苯并三唑(HOBT)作为催化剂,N,N-二异丙基乙胺(DIPEA)作为有机碱,二甲基甲酰胺(DMF)作为溶剂,进行酰胺键生成的关键反应,将乙二胺作为连接臂,通过共价键链接胸腺嘧啶与不对称方酸菁染料,制得一种非对称的基于胸腺嘧啶的近红外方酸菁染料探针,其具有大的共轭体系,电子可以在吲哚环的氮端到方酸环的氧端上自由移动,呈现离子性,最终产物呈现电中性。反应条件容易控制,通过简单的处理就能够得到纯的产物。该探针具有选择性好、水溶性好、灵敏度高、可用于活体检测等优点,可在不同的溶剂体系中识别不同的离子,具有高应用性。目前的近红外染料探针对于离子的识别主要集中在Fe3+的识别上,本发明解决了在近红外吸收区域对Fe2+和Co2+选择性识别的问题。胸腺嘧啶上的羰基以及二级胺都有孤对电子,可以与缺电子的金属离子通过氢键作用配位,利用胸腺嘧啶的结构特征,将它作为离子识别的靶点,对于识别Fe2+和Co2+起着决定性的作用。通过改变不同的溶剂,该探针可以通过吸收强度的变化,选择性地识别Fe2+和Co2+,对Fe2+的识别在颜色上表现为从蓝色变成了橙黄色,对Co2+的识别在颜色上表现为从蓝色变成了无色。
