HIF prolyl hydroxylase 2 (PHD2) inhibitors represent a novel approach for treating HIF-related diseases. This study reports the first application of photoremovable protecting group to the photoactivatable inhibitor (7) of PHD2. It allows the inhibitory activity for PHD2 to be controlled by light irradiation, subsequently stabilizing HIF and promoting expression of the target gene. Light activation to stabilize HIF offers promising potentials for the tissue-specific therapies for HIF-related disease by light irradiation onto target tissues.
