  Synthesis of urea analogues bearing N-alkyl-N'-(thiophen-2-yl) scaffold and evaluation of their innate immune response to toll-like receptors

  摘要：

  Previous high throughput virtual screening of 10 million-compound and following cell based validation led to the discovery of a novel, nonlipopeptide-like chemotype ZINC 6662436, as toll-like receptor 2 (TLR2) agonists. In this report, compounds belonging to four areas of structural modification of ZINC6662436 were evaluated for biological activity using human HEK-Blue TLR2 reporter cells, and human THP-1 monocytic cells, yield SMU-C13 as an optimized, direct and high potent (EC50 = 160 nM) agonist of human TLR2. Moreover, preliminary mechanism studies indicated that SMU-C13 through activates TLR1 and TLR2 then stimulates the NF-kappa B activation to trigger the downstream cytokines, such as TNF-alpha and secreted alkaline phosphatase (SEAP).

  4,5,6,7-四氢苯并噻吩 2,3 衍生物的发现、合成和体外表征作为视黄酸受体相关孤儿受体 γt 的有效调节剂

  摘要：

  视黄酸受体相关孤儿受体γt（RORγt）是一种在多种组织中表达的核受体，是治疗炎症和自身免疫性疾病、代谢性疾病和耐药癌症类型的潜在药物靶点。我们在此报告了 RORγt 4,5,6,7-四氢苯并噻吩调节剂的 2,3 衍生物的发现。我们还报告了一组这些衍生物在酸性/中性 pH 下的溶解度、小鼠/人/狗/大鼠微粒体稳定性、Caco-2 和 MDR1-MDCKII 渗透性。对于这组调节剂，与激动剂锁水合相比，空间冲突和推拉机制引起的反向激动会导致蛋白质构象更大的不稳定性。独立于这两种机制，我们观察到由于与 Cys320-Glu326 和 Arg364-Phe377 亲水区域的相互作用，所测试的 4,5,6,7-四氢苯并噻吩的 2,3 衍生物对 RORγt 具有基础调节活性。当前研究中报告的药物发现方法可用于发现核受体和其他球状蛋白靶点的调节剂。
