Efficient synthesis of homocarbonyltopsentine Ia, starting from readily available triiodoimidazole 9 and 3-formylindoles 2 and 18 is described. The key steps of the synthesis are selective halogen-metal exchanges at the imidazole nucleus and subsequent addition to formylated indoles.

N-Alkoxymethylation of heterocycliccompounds with diethyl phosphite via cleavage of P–O bond was investigated and a series of N3-ethoxymethylated heterocycliccompounds were synthesized. A mechanism in which diethyl phosphite acts as an efficient surrogate of ethanol was proposed and supported by several evidences.

The nuclear hormone receptor retinoic acid receptor-related orphan C2 (RORC2, also known as RORγt) is a promising target for the treatment of autoimmune diseases. A small molecule, inverseagonist of the receptor is anticipated to reduce production of IL-17, a key proinflammatory cytokine. Through a high-throughput screening approach, we identified a molecule displaying promising binding affinity for
核激素受体视黄酸受体相关的孤儿C2(RORC2,也称为RORγt)是治疗自身免疫性疾病的有希望的靶标。预期该受体的小分子反向激动剂会减少关键的促炎细胞因子IL-17的产生。通过高通量筛选方法,我们鉴定了一种分子,该分子显示出对RORC2的有希望的结合亲和力,抑制Th17细胞中IL-17的产生以及对相关RORA和RORB受体同工型的选择性。铅优化以提高这种命中的效力和代谢稳定性为重点,主要集中在两个关键设计策略上,即,通过提高亲脂性效率和结构指导的构象限制驱动的迭代优化,以实现最佳的基态能量学和最大化受体停留时间。N-(3-(1-异丁酰基哌啶-4-基)-1-甲基-4-(三氟甲基)-1 H-吡咯并[2,3 - b ]吡啶-5-基)苯甲酰胺为强效且选择性的RORC2逆激动剂,在临床前体内动物模型中,口服给药后表现出良好的代谢稳定性,口服生物利用度以及降低IL-17水平和皮肤炎症的能力。
