Dynamic nucleophilic aromatic substitution of tetrazines (SNTz) has been employed to build theranostic prodrugs that are activated by hydrogen sulfide. H2S is typically found in high concentrations in some kinds of cancer cells and it is able to trigger the disassembly of tetrazine prodrugs. In such a way, a dual release of drugs and/or fluorescent compounds can be selectively triggered.
