摘要
将一种具有近红外荧光性能的氟硼荧染料(BDDIPY)作为显影基团,制成新型的检测肿瘤细胞的近红外荧光分子探针。首先以氟硼二吡咯烷(BOD)为起始原料,通过缩合反应,将具有强供电子作用的N-苯基亚氨基二苄引入到氟硼荧中,得到了荧光光谱处于近红外区的氟硼荧化合物,接着用N-羟基琥珀酰亚胺为活化剂,将具有肿瘤亲和力的甘氨酸引入到荧光基团-氟硼荧(BDDIPY),最终得到甘氨酸-氟硼荧近红外荧光探针,并对其结构进行了核磁和质谱表征,并进行了光学和生物学性能测试。实验结果显示:甘氨酸-氟硼荧近红外荧光分子探针的荧光发射波长大于700 nm,与肺癌细胞(GLC-82)具有较好的亲和力,达到23.65,是一个具有良好应用前景的检测肿瘤细胞的近红外荧光分子探针。
In this paper, we used a BDDIPY with near-infrared fluorescent properties as imaging group to produce a new type of near infrared fluorescence molecular probe for detecting tumor cells. Firstly, BOD was used as the starting materials, and then introduced N-phenyl iminodibenzy] with strong electron-dona- ting ability into the BDDIPY dye through condensation reaction. Then we gained the glycine-BDDIPY com- pound which has the near-infrared fluorescence spectrum. Next, with N-hydroxy succinimide as an activa- tor,glycine methyl ester was introduced into the BDDIPY. Finally we get a biocompatible glyeine-BDDIPY molecular fluorescent probe which having affinity with tumors. All the intermediates and target products were characterized by 1H NMR and MALDI-TOF. These BODIPYs were tested to characterize their optical and biological properties. Experimental results showed that the fluorescence emission wavelength of glycine- BDDIPY is longer than 700 nm. And it had a good affinity with lung cancer cells at about 23.65. This indicates that glycine-BDDIPY has a good application prospect for detecting tumor cells.
