autoimmune diseases, and inhibition of RORγt with small molecules thus holds great potential as a therapeutic strategy. RORγt has a unique allosteric ligand binding site in the ligand binding domain, which is distinct from the canonical, orthosteric binding site. Allosteric modulation of RORγt shows high potential, but the targeted discovery of novel allosteric ligands is highly challenging via currently
核受体RORγt是T辅助细胞17(Th17)细胞分化和增殖以及促炎性细胞因子(如IL-17a)产生的关键正调控因子。该途径的失调可导致各种自身免疫性疾病的发展,因此用小分子抑制RORγt具有作为治疗策略的巨大潜力。RORγt在配体结合结构域中具有独特的变构配体结合位点,其不同于典型的正构结合位点。RORγt的变构调节显示出很高的潜力,但是通过目前可用的方法,靶向发现新的变构配体具有很高的挑战性。在此,我们介绍RORγt的共价正构化学探针,该探针封闭正构,正构配体的结合,但仍允许变构配体结合。
