MRL-871 (compound 3) is a potent and allosteric retinoic acid receptor-related orphan receptor γt (RORγt) inverse agonists with an IC50 of 12.7 nM. MRL-871 has a distinct isoxazole chemotype and effectively reduces IL-17a mRNA production in EL4 cells[1].
MRL-871 (compound 3; 10 μM, 24h) significantly reduces IL-17a mRNA expression 48-fold in EL4 cells[1].
