A549 and HeLa cells. Cell imaging data reveal that AFR1, AFR1E, and AFR2 are mainly located in the mitochondria, while AFR3 is a lysosome tracker. As far as we know, NIR AFR3 is the longest fluorescent rhodamine derivative containing the amino group. These amino group-containing AFR dyes hold great potential in fluorogenic detection, biomolecule labeling, and cell imaging.
通过基于3-香豆素酮衍生物的有效缩合,构建了具有氨基的氨基苯并呋喃-融合罗丹明染料(AFR染料)。AFR染料具有显着改善的性能,包括深红色和近红外发射,大的斯托克斯位移,良好的光稳定性和宽的pH稳定性。3-(4,5-二甲基噻唑-2-基)-2,5-二苯基-2 H-四唑鎓测定实验表明,这些AFR染料对A549和HeLa细胞均具有低细胞毒性,因此具有生物相容性。细胞成像数据显示AFR1,AFR1E和AFR2主要位于线粒体中,而AFR3是一个溶酶体追踪器。据我们所知,NIR AFR3是含有氨基的最长的荧光罗丹明衍生物。这些含氨基的AFR染料在荧光检测,生物分子标记和细胞成像中具有巨大的潜力。
