Discovery of novel pyrazole-containing benzamides as potent RORγ inverse agonists

The nuclear receptor RORγ plays a central role in controlling a pro-inflammatory gene expression program in several lymphocyte lineages including TH17 cells. RORγ-dependent inflammation has been implicated in the pathogenesis of several major autoimmune diseases and thus RORγ is an attractive target for therapeutic intervention in these diseases. Starting from a lead biaryl compound 4a, replacement of the head phenyl moiety with a substituted aminopyrazole group resulted in a series with improved physical properties. Further SAR exploration led to analogues (e.g., 4j and 5m) as potent RORγ inverse agonists.
