Here we report the first use of ligand‐directed proximity accelerated bioconjugation chemistry in the tandem delivery and release of a therapeutic payload. To do this, we designed a nitrophenol carbonate for ligand‐directed in situ bioconjugation of a prodrug payload to a protein. The transient nature of our conjugation chemistry renders the protein a depot for time‐dependent release of active drug following hydrolysis and self‐immolation. In our model system, using an immunostimulant prodrug, biotin ligand, and avidin protein, we observe release of bioavailable immunostimulant both spectroscopically and with an immune cell line over 48 h. Avidin co‐crystalized with the nitrophenolate directing group verified the binding pose of the ligand and offered insight into the mechanism of in situ bioconjugation. Overall, this scaffold warrants further investigation for the time‐dependent delivery of therapeutics and use in protein ligand pairs beyond biotin and avidin used for this work. Ligand‐directed proximity accelerated bioconjugation to deliver a therapeutic payload using a novel nitrophenol carbonate derivative. In this work, we demonstrate the utility for the ligand‐directed in situ labeling of a protein avidin with an immunostimulant prodrug. This renders the target protein a depot for time‐dependent release of active drug. The mechanism is probed using crystallography, and time‐dependent drug release is demonstrated in vitro.
