A new phenyl (3-phenylpyrrolidin-3-yl)sulfone series of RORγt inverse agonists was discovered utilizing the binding conformation of previously reported bicyclic sulfonamide 1 . Through a combination of structure-based design and structure-activity relationship studies, a polar set of amides at N 1-position of the pyrrolidine ring and perfluoroisopropyl group at para -position of the 3-phenyl group were identified as critical structural elements to achieve high selectivity against PXR, LXRα, and LXRβ ...
