PubMed Abstract: The retinoic acid receptor-related orphan receptor-gamma-t (RORγt) is the master transcription factor responsible for regulating the development and function of T-helper 17 (Th17) cells, which are related to the pathology of several autoimmune disorders. Therefore, RORt is an attractive drug target for such Th17-mediated autoimmune diseases. A structure-activity relationship (SAR) study of lead compound 1 yielded a novel series of RORt inhibitors, represented by compound 6. Detailed SAR optimization, informed by X-ray cocrystal structure analysis, led to the discovery of a potent orally bioavailable RORt inhibitor 25, which inhibited IL-17 production in the skin of IL-23-treated mice by oral administration.
