The fluorescent probes based on Tröger's base motive with both coumarin and cyanine substitution 11-13 have been synthesized by multi-step synthesis in high overall yields. Intracellular localization of prepared probes have been tested using four different cell lines (HF-P4, BLM, U-2 OS and A-2058). Prepared probes have intensive green and red fluorescence. Co-localization with commercial lysosome specific marker LysoTracker Blue DND 22 has been confirmed that all prepared fluorescent probes labeled lysosomal compartment with high selectivity and probes show excellent brightness at low concentration.
