Traceable in-cell synthesis and cytoplasm-to-nucleus translocation of a zinc Schiff base complex as a simple and economical anticancer strategy.

We have proposed a facile and cheap cancer therapeutic strategy by in-cell synthesizing theranostic Zn Schiff base complexes with nuclear targeting and DNA damaging capability. The in-cell synthesis can be traced via a green-to-blue fluorescence shift, and the subsequent cytoplasm-to-nucleus translocation realizes cancer-specific therapy both in vitro and in vivo.
