Two mitochondrial-targeted fluorescent probes, 2 and 3, based on a BODIPY scaffold and one or two piperidinyl groups were easily synthesized by Knoevenagel condensation. The biological imaging applications of the two probes 2 and 3 in live HepG2 cells reveal that these two probes display excellent mitochondrial imaging ability. Thus, these probes appear as promising tools for visualization of mitochondrial within live cells.

基于红色/近红外中性BODIPY的荧光探针，用于照亮线粒体

通过Knoevenagel缩合可以轻松合成两个基于BODIPY支架的线粒体靶向荧光探针2和3，以及一个或两个哌啶基。两种探针2和3在活HepG2细胞中的生物学成像应用表明，这两种探针显示出优异的线粒体成像能力。因此，这些探针似乎是用于可视化活细胞内线粒体的有前途的工具。
