Description

一种基于环三聚磷腈的荧光材料及其制备方法和应用
技术领域
本发明属于荧光探针领域,特别涉及一种基于环三聚磷腈的荧光材料的制备方法及其溶酶体靶向的应用。
背景技术
溶酶体是具有单层膜囊状结构的细胞器,内含多种水解酶,可分解蛋白质、核酸、多糖等生物大分子。溶酶体参与生命活动中很多重要过程如细胞内物质运输、代谢、细胞凋亡、自体吞噬等。异常的溶酶体pH变化则常常与矽肺、风湿,癌症、炎症等疾病密切相关。因此,溶酶体的定位研究具有十分重要的生物学和医学价值。荧光方法作为生命过程"可视化"的重要方法之一,由于其高灵敏性及可应用于活细胞成像等优点,已成为检测细胞内溶酶体的一种重要方法。如吖啶橙、中性红染料及LysoTracker系列荧光探针已商业化。因此,开发多样化溶酶体定位的荧光探针显得非常必要。
六氯环三磷腈环(N3P3Cl6,HCCP)是一种经典的含磷杂环化合物,可通过选择性取代而易功能化,生成各种含磷衍生物,可广泛应用于阻燃,催化,生物,医学和成像领域。近年来,随着荧光的发展,环三聚磷腈环已发展成为一种通用的功能平台,可以用多种功能衍生物制备用于荧光检测和成像领域。当与各种不同类型的荧光团连接时,环三磷腈的衍生物通常呈现出与单体不同的特殊光学性质。此外调研文献可知,萘酰亚胺类衍生物具有性能优良的荧光特性,广泛应用于荧光分子的构建;吗啉结构的分子嗜酸性,具有一定的溶酶体选择性。基于以上性质我们致力于开发一种基于环三聚磷腈,接枝萘酰亚胺-吗啉基团的荧光材料,应用于高效探测溶酶体。
检索国内外文献尚没有发现关于利用基于环三聚磷腈的荧光材料用于溶酶体靶向的研究报道。

实施例2
制备MNI和HCCP-MNI浓度为1mmol/L的储备液,溶剂为二甲基亚砜,分别将制备的储备液取20μL加不同溶剂稀释至2mL,材料最终浓度为0.01mmol/L。荧光分光光度计测定激发波长为390nm,激发带宽5nm,发射带宽2nm。若以Dimroth ET(30)值作为溶剂的极性参数,与MNI和HCCP-MNI在不同溶剂中的荧光光谱峰值波长λmax作图,如图9所示,(A)为HCCP-MNI,(B)为MNI。结果显示在不同的溶剂条件下荧光光谱峰值波长λmax与ET(30)呈线性关系。
取HCCP-MNI浓度为1mmol/L的储备液,加入到pH为4-9的PBS缓冲溶液中,以HCCP-MNI的荧光光谱为纵坐标作图,如图10所示。结果显示,HCCP-MNI在不同的pH条件下的荧光状态稳定,并且在酸性条件下,亮度更强,有利于溶酶体靶向。取制备MNI和HCCP-MNI浓度为1mmol/L的储备液,以超纯水为分散相,稀释到二甲基亚砜含量为1%,通过马尔文激光粒度仪(Malvern,ΜK,633nm激光)对其水动力学粒径及表面电势进行了表征,如图11的(A)和(B)。结果证明,HCCP-MNI毒性比较低。
实施例3
本实施例利用CCK-8法评价MNI和HCCP-MNI对小鼠成纤维细胞(L929)抑制效果:收集对数生长期L929细胞,按照10,000细胞每孔的密度接种在96孔细胞培养板上,培养于含10%FBS和1%双抗的RPMI 1640培养基中,于5%CO2,37℃条件下孵育过夜。弃掉培养基后,每孔更换含有材料(相对MNI浓度为2.5、5、7.5、10、12.5、15、17.5、20、22.5、25μM)或PBS(对照组)的新鲜培养基,5%CO2,37℃继续孵育12小时。随后弃掉原培养基,加入含100μL含有10%CCK-8的新鲜培养基溶液,继续培养4h后,多功能酶标仪测试波长450nm下测试吸光值,结果如图12所示。
与PBS缓冲溶液对照组相比,在试验浓度范围内HCCP-MNI处理过的L929细胞,其存活率均在80%以上,说明HCCP-MNI本身没有毒性,具有更高的生物安全性。因此HCCP-MNI可以在细胞内行使其生物学功能。
实施例4
以L929细胞为模型细胞来检验细胞对MNI和HCCP-MNI的吞噬效果。以15×105/孔的密度将L929细胞种于直径35mm激光共聚焦专用培养皿中,于37℃及5%CO2条件下培养过夜。随后将培养基换成1000μL含浓度为10%FBS的RPMI 1640培养基,培养基中分别加入MNI、HCCP-MNI材料加入细胞中转染4h。使用PBS缓冲溶液清洗细胞,之后用商业溶酶体染色液染色1h,使用PBS缓冲溶液清洗细胞,每个培养皿加入200μL,2.5%的戊二醛固定液,固定5min,去除固定液,用DAPI和商业溶酶体染色液染色。激光共聚焦显微镜观察两种材料在L929细胞内的分布情况(如图13)。
结果显示,将MNI和HCCP-MNI与细胞培养4h后,HCCP-MNI的绿色荧光分布在细胞胞浆中。那么可以说明HCCP-MNI能够很好地进入细胞,并且进入细胞后与商业溶酶体探针对比显现出优异的溶酶体选择性。
