| Description | SR 1555 is a novel RORγ-specific synthetic ligand. |
| In vitro | 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 (IC50: ≈ 1.5 μM). In competitive radioligand binding assays, SR1555 bound to RORγ (IC50: 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 [1]. |

Solution Preparation Table | ||||||||||||||||
DMSO
| ||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
