Conditional Relay Activation of Theranostic Prodrug by Pretargeting Bioorthogonal Trigger and Fluorescence-Guided Visible Light Irradiation.

Bioorthogonalized light-responsive click-and-uncage platform has enabled precise cell surface engineering and timed payload release, but most of such photoactivatable prodrugs have "always-on" photoactivity leading to the dark toxicity. On the other hand, the conditionally activatable photocage is limited to the application of fluorogenic probe/photosensitizer liberation. Herein, we devise a conditionally activatable theranostic platform based on the tetrazine (Tz)-boron-dipyrromethene (BODIPY) construct, in which tetrazine serves as a quencher motif to disable both the fluorescence and photoresponsivity of BODIPY.
