  一种新型的高度选择性的组胺H4受体拮抗剂治疗特应性皮炎的发现

  摘要：

  组胺H4受体（H4R）是G蛋白偶联受体家族的成员，被认为是治疗特应性皮炎（AD）的潜在治疗靶标。已经公开了许多H4R拮抗剂，但是尚未开发出控制AD中瘙痒和炎症的有效药物。在这里，我们发现了一类新型的口服H4R拮抗剂，显示出强大的止痒和消炎活性以及对脱靶的极好的选择性。在内部构建的基于药效团的虚拟筛选系统成功鉴定了初始命中化合物9，随后的同源性模型指导的优化有效地引导我们发现了吡啶并[2,3- e ] tetrazolo [1,5- a ] pyrazine类似物48是一种有效且高度选择性的H4R拮抗剂的新型化学型。重要的是，在几种AD小鼠模型中，口服给药的化合物48在止痒和抗炎方面显示出显着的功效，并具有良好的药代动力学（PK）特征。因此，这些数据强烈表明我们的化合物48是用于治疗AD的有前途的临床候选药物。

  Synthesis of a 6-Methyl-7-deaza Analogue of Adenosine That Potently Inhibits Replication of Polio and Dengue Viruses

  摘要：

  Bioisosteric deaza analogues of 6-methyl-9-beta-D-ribofuranosylpurine, a hydrophobic analogue of adenosine, were synthesized and evaluated for antiviral activity. Whereas the 1-deaza and 3-deaza analogues were essentially inactive in plaque assays of infectivity, a novel 7-deaza-6-methyl-9-beta-D-ribofuranosylpurine analogue, structurally related to the natural product tubercidin, potently inhibited replication of poliovirus (PV) in HeLa cells (IC50 = 11 nM) and dengue virus (DENV) in Vero cells (IC50 = 62 nM). Selectivity against PV over cytotoxic effects to HeLa cells was > 100-fold after incubation for 7 h. Mechanistic studies of the 5'-triphosphate of 7-deaza-6-methyl-9-beta-D-riboluranosylpurine revealed that this compound is an efficient substrate of PV RNA-dependent RNA polymerase (RdRP) and is incorporated into RNA mimicking both ATP and GTP.
