SR 1555 is a novel RORγ-specific synthetic ligand .
Retinoic acid receptor-related nuclear receptor (ROR) belongs to the nuclear receptor superfamily, a group of structurally related, ligand-dependent transcription factors. RORs function as key regulators of many physiological processes that occur during embryonic development and in the adult . RORγ plays a dominant role in T cell differentiation, particularly in the development of TH17 cells, which are implicated in autoimmune diseases such as multiple sclerosis and rheumatoid arthritis .
In vitro: In a GAL4-NR chimeric co-transfection assay, SR1555 was devoid of LXR, FXR, and RORα activity, but it dose-dependently repressed the activity at RORγ with an IC50 of ≈ 1.5 μM. In competitive radioligand binding assays, SR1555 bound to RORγ with an IC50 of 1 μM. SR1555 specifically targeted RORγ and inhibited its transcriptional activity leading to suppression of IL-17 gene expression. EL4 cells treated SR1555 (10 μM) for 24 h inhibited Il17a gene expression by greater than 70%, demonstrating that SR1555 could inhibit the expression of this TH17 mediated cytokine . SR1555 not only inhibited TH17 cell development and function but also increased the frequency of T regulatory cells .
