Difopein (TFA), a specific and competitive inhibitor of 14-3-3 protein (a highly conserved eukaryotic regulatory molecule), blocking the ability of 14-3-3 to bind to target proteins and inhibits 14-3-3/Ligand interactions. Difopein (TFA) leads to induction of apoptosis and enhances the ability of cisplatin to kill cells.

NBD-Cl is a nonfluorescent compound that becomes highly fluorescent after reaction with amino or thiol groups.

FFAGLDD is MMP9 selective cleavage peptides, which used for cytosolic delivery of Doxorubi-cin (DOX) and achieve temporally and spatially controlled slow drug delivery and release.
