报告摘要:In a screen for small molecule inhibitors of RORγ, we fortuitously discovered that a class of aryl amide compounds behaved as functional activators of the IL-17 reporter in Jurkat cells. Three of these compounds were selected for further analysis and found to activate the IL-17 reporter with potencies ~0.1μM measured by EC50. These compounds were shown to directly bind to RORγ by Circular Dichroism-based thermal stability experiments. Furthermore, they can enhance an in vitro Th17 differentiation process in human primary T cells. As RORγremains an orphan nuclear receptor, discovery of these aryl amide compounds as functional agonists will now provide pharmacological tools for us to dissect functions of RORγ and facilitate drug discovery efforts for immune modulating therapies.
