A novel series of carbazole carboxamides was discovered as potent RORγt inverse agonists using a scaffold hybridization strategy. Structure-activityrelationship exploration on the amide linker, carbazole ring and arylsulfone moiety of the hybrid amide 3a led to identification of potent RORγt inverse agonists. Compound 6c was found to have a good RORγt activity with an IC50 of 58.5 nM in FRET assay
