  Zika virus (ZIKV) is a member of the Flaviviridae family that can cause neurological disorders and congenital malformations. The NS2B-NS3 viral serine protease is an attractive target for the development of new antiviral agents against ZIKV. We report here a SAR study on a series of substrate-like linear tripeptides that inhibit in a non-covalent manner the NS2B-NS3 protease. Optimization of the residues

  A general and efficient method for a metal-free one-pot synthesis of highly substituted fused imidazole-containing 5,5- and 5,6-fused bicyclic heterocycles is described. Starting from commercially available substrates and reagents, the reaction proceeds through two C–N bond formations and an oxidative dehydrogenation to form highly substituted products in good to excellent yield.

  Inverse agonists of the nuclear receptor RORC2 have been widely pursued as a potential treatment for a variety of autoimmune diseases. We have discovered a novel series of isoindoline-based inverse agonists of the nuclear receptor RORC2, derived from our recently disclosed RORC2 inverse agonist 2. Extensive structure–activity relationship (SAR) studies resulted in AZD0284 (20), which combined potent

  核受体 RORC2 的反向激动剂已被广泛视为多种自身免疫性疾病的潜在治疗方法。我们发现了一系列新型的基于异吲哚啉的核受体 RORC2 反向激动剂，源自我们最近公开的 RORC2 反向激动剂2 。广泛的构效关系 (SAR) 研究产生了 AZD0284 ( 20 )，它结合了对原代人 T H 17 细胞 IL-17A 分泌的有效抑制，在临床前物种中具有出色的代谢稳定性和良好的 PK。在两项临床前体内研究中，化合物20减少了小鼠胸腺细胞数量，并在咪喹莫特诱导的炎症模型中显示出含有 IL-17A 的 γδ-T 细胞以及 IL-17A 和 IL-22 RNA 的剂量依赖性减少。基于这些数据和良好的安全性， 20 项研究已进入 1 期临床研究。
