  • PubMed Abstract: 

    Retinoic acid receptor-related orphan receptor γt (RORγt) agonists are expected to provide a novel class of immune-activating anticancer drugs via activation of Th17 cells and Tc17 cells. Herein, we describe a novel structure-based functionality switching approach from in house well-optimized RORγt inverse agonists to potent RORγt agonists. We succeeded in the identification of potent RORγt agonist 5 without major chemical structure change. The biochemical response was validated by molecular dynamics simulation studies that showed a helix 12 stabilization effect of RORγt agonists. These results indicate that targeting helix 12 is an attractive and novel medicinal chemistry strategy for switching existing RORγt inverse agonists to agonists.
