Abstract: The cytosolic delivery of hydrophilic, anionic molecular probes and
therapeutics is a major challenge in chemical biology and medicine.
Herein, we describe the design and synthesis of peptide-cage hybrids
that allow an efficient supramolecular binding, cell membrane
translocation and cytosolic delivery of a number of anionic dyes,
including pyranine, carboxyfluorescein and several sulfonate-containing
Alexa dyes. This supramolecular caging strategy is successful in
different cell lines, and the dynamic carrier mechanism has been
validated by U-Tube experiments. The high efficiency of the reported
approach allowed intracellular pH tracking by exploiting the ratiometric
excitation of the pyranine fluorescent probe
