Identification of an allosteric binding site for RORγt inhibition

Abstract: RORγt is critical for the differentiation and proliferation of Th17 cells associated with several chronic autoimmune diseases. We report the discovery of a novel allosteric binding site on the nuclear receptor RORγt. Co-crystallization of the ligand binding domain (LBD) of RORγt with a series of small-molecule antagonists demonstrates occupancy of a previously unreported allosteric binding pocket. Binding at this non-canonical site induces an unprecedented conformational reorientation of helix 12 in the RORγt … Show more

“…SR1078 was also shown to have direct interaction with RORγt via thermal shift assay as measured by Circular Dichroism (CD) 17 . The lack of potency in displacing the radiolabeled orthosteric inverse agonist T0901317 is likely due to SR1078 binding in the recently described allosteric pocket on RORγt 20 . Initial SAR of the benzamide ring suggests that substituents are tolerated at the ortho-position leading to SR0987 (Fig.…”

“…Given that activation of RORgtc ontrolsg ene programst hat enhancei mmunity,i ncrease IL17 production, and decrease immune suppression, [18,19] this NR has become ah igh-priority targetf or numerous pharmaceutical companies over the past decade. [20][21][22][23][24][25] Significant efforts to developsmall molecules that exhibit selectivei nverse agonist(repressive) activity against RORg for the treatment of autoimmune diseases has ultimately resulted in severalc linicalc andidates. [26,27] Ap lethora of diverse chemical scaffolds have been published that bind to the RORg oxysterol orthosteric site such as SR2211, [28] indole 1, [21] triazole 2, [22] and biaryl amide 3 [23] (Figure 1).…”

“…Following these promising preclinical results, several clinical trials with oral and topical RORγ inhibitors such as: VTP-43742, GSK2981278, ABBV-553, ARN-6039 and AZD-0284 have been started in psoriasis, MS, RA and uveitis patients (NCT02555709; NCT03004846; NCT03145948; NCT02976831). While several other inhibitors are still at the preclinical stage, an antagonist that inhibits RORγt with an allosteric mechanism, which could lead to increased selectivity, has also been reported to have promising in vitro activity [131]. …”
