Abstract
Bioorthogonal reactions hold significant promise for applications in chemical biology. Despite their potential, nitriles have often been overlooked as reactive functional groups for selective bioconjugation. The condensation reaction between cyanopyridines and 1,2-aminothiols stands out as a particularly favorable nitrile modification strategy that proceeds under biocompatible conditions. Cyanopyridines can be seamlessly incorporated into peptides and proteins through both chemical and biotechnological approaches. Similarly, the selective integration of 1,2-aminothiols into peptides and proteins is achievable, leveraging the uniquely reactive N-terminal cysteine functional group.
