  • PubMed Abstract: 

    • 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 ...

    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. Further optimization led to the discovery of (1 R ,4r)-4-(( R )-3-((4-fluorophenyl)sulfonyl)-3-(4-(perfluoropropan-2-yl)phenyl)pyrrolidine-1-carbonyl)cyclohexane-1-carboxylic acid ( 26 ), which displayed excellent selectivity, desirable liability and pharmacokinetic properties in vitro , and a good pharmacokinetic profile in mouse. Oral administration of 26 demonstrated dose-dependent inhibition of IL-17 production in a mouse IL-2/IL-23-induced pharmacodynamic model and biologic-like efficacy in an IL-23-induced mouse acanthosis model.
