Nuclear hormone receptors (NHRs) are representatives of a large class of proteins within cells. They act as receptors for a wide range of molecules, such as vitamin A-derivative retinoids, steroid and thyroid hormones, and others. Activated by binding of the signal molecule, the ligand–NHR complex changes its conformation and modifies the expression of certain genes by binding to control elements in the DNA. Thus, NHRs play a major role in embryonic development and adult homeostasis. Over 10% of FDA-approved drugs target NHRs as perspective objects in the control of various diseases.

Nuclear Hormone Receptor Ligands Library is composed of 453 small ligands. The collection includes ligands that display all major types of action on NHR targets: agonistic, antagonistic, and inverse agonistic.
