Essential for thymopoiesis and the development of several secondary lymphoid tissues, including lymph nodes. Involved in lineage specification of uncommitted CD4(+) T-helper cells into Th17 cells. Regulate the expression of several components of the circadian clock. Publication Abstract from PubMed A new phenyl (3-phenylpyrrolidin-3-yl)sulfone series of RORgammat 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 N1-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, LXRalpha, and LXRbeta. Further optimization led to the discovery of (1R,4r)-4-((R)-3-((4-fluorophenyl)sulfonyl)-3-(4-(perfluoropropan-2-yl)phenyl)pyr rolidine-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.
