Photo- and Tetrazine-Responsive Modulation of trans-Zeatin

Photoirradiation and small organic molecule triggering of appropriately designed caged hormones enable the control and manipulation of the corresponding biological processes with high spatial and temporal resolution. Caged trans-zeatin substituted with nitrobenzene carbonates as photoremovable protecting groups and trans-cyclooctene as the tetrazine-responsive motif have been synthesized. A smooth release of the trapped transzeatin molecule has been achieved, permitting targeted perturbation of biological processes, including degradation, glucosylation, and recognition by appropriate enzymes.
