Nuclear hormone receptors (NHRs) represent a diverse class of ligand-dependent transcriptional regulators. NHRs that have been rendered functionally inactive due to mutations that abrogate proper ligand binding can often be rescued by appropriately designed hormone analogues. The analogue-specific receptor-ligand pairs provide an ideal platform from which to develop new chemogenomic tools for the spatial and temporal control of gene expression. Here, we describe the synthesis and in vitro assessment of a photocaged VDR agonist specific to a mutant NHR that is associated with vitamin D-resistant rickets. The results provide insight into the utility of the agonist as a potential tool for photoinduced gene patterning.
