Function
[RORG_HUMAN] Possible nuclear receptor for hydroxycholesterols, the binding of which strongly promotes coactivators recruitment. Essential for thymopoiesis and the development of several secondary lymphoid tissues, including lymph nodes. Involved in lineage specification of uncommitted CD4(+) T-helper cells into Th17 cells. Regulate the expression of several components of the circadian clock.
Publication Abstract from PubMed
Structure-based and pharmacophore-based virtual screening in combination with combinatorial chemistry and X-ray crystallography led to the discovery of a new class of benzothiadiazole dioxide analogs with functional activity as RORC inverse agonists. The early RORC SAR compound 14 exhibited RORC inhibition in a cell based reporter gene assay of 5.7muM and bound to RORC with an affinity of 1.6muM in a fluorescence polarization assay displacing a ligand binding site probe. Crystallography confirmed the binding mode of the compound in the ligand binding domain displaying the engagement of a novel sub pocket close to Ser404. Subsequent optimization yielded compounds with enhanced RORC inverse agonist activity. The most active compound 19 showed an IC50 of 440nM in a human PBMC assay.
