  lymph-node genesis. In this study, we utilized a screening system with full-length RORγt including DBD, HD and LBD to evaluate the activities of a synthesized library of tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidine derivatives. We identified a potent lead compound (28) that effectively inhibited Th17 cell differentiation. Docking and structure-activity relationship (SAR) studies showed that compound

  类视黄醇相关的孤儿受体γ-t（RORγt）属于核受体超家族，在T辅助17细胞（Th17）的发展和成熟以及淋巴结的发生中起着至关重要的作用。由于已证明Th17细胞是人类自身免疫和炎性疾病的主要效应物，因此已发现RORγt的激动剂和拮抗剂是治疗这些疾病的有希望的先导。由于已经阐明并详细研究了LBD的结构和结合口袋，目前大多数RORγt抑制剂的研究都集中在RORγt的配体结合域（LBD）上。最近的研究表明，RORγt的铰链结构域（HD）显着参与RORγt的SUMOylation，因此特别影响T细胞的发育，但不影响淋巴结的发生。这些发现突出了RORγtHD作为RORγt抑制剂靶标的潜力，该抑制剂可以特异性抑制Th17相关活性而不会影响淋巴结的发生。在这项研究中，我们利用包括DBD，HD和LBD在内的具有全长RORγt的筛选系统来评估四氢苯并[4,5]噻吩并[2,3-d]嘧啶衍生物的合成文库的活性。
