Modular design of optically controlled protein affinity reagents

Abstract

Photopharmaceuticals can, in principle, be created by linking photoswitchable moieties to bioactive molecules. However, a general strategy for converting a therapeutic agent into its photoswitchable version is not currently available. Herein we propose a generalizable, modular approach for obtaining light controllable bioactive agents by modifying the scaffold of a protein affinity reagent using an azobenzene photoswitch.
