showed that increased levels of cyclic AMP down-regulate lung inflammatory changes, stimulating the interest in phosphodiesterase (PDE)4 as therapeutic target. Here, we described the synthesis, pharmacological profile and docking properties of a novel sulfonamide series (5 and 6a-k) designed as PDE4 inhibitors. Compounds were screened for their selectivity against the four isoforms of human PDE4 using
先前的研究表明,循环AMP的水平升高会下调肺部炎症变化,从而激发人们对磷酸二酯酶(PDE)4作为治疗靶标的兴趣。在这里,我们描述了设计为PDE4抑制剂的新型磺酰胺系列(5和6a-k)的合成,药理作用和对接特性。使用IMAP荧光偏振方案筛选化合物对人PDE4四种同工型的选择性。在A / J小鼠中研究了对变应原或LPS诱导的肺部炎症和气道高反应性(AHR)的影响,而甲苯噻嗪/氯胺酮诱导的麻醉试验被用作啮齿动物呕吐的行为相关因素。与咯利普兰相比,最有希望筛选的化合物6a(LASSBio-448)对PDE4D / PDE4A或PDE4D / PDE4B表现出更好的抑制指数。因此,对LASSBio-448的假定相互作用的对接分析显示,PDE4A和PDE4C的活性位点具有相似的姿势,但与PDE4B和PDE4D的取向略有不同。LASSBio-448(100 mg / kg,口服),在激发前1小时,抑制了
