cascade of inflammation, and reducing the inflammatory response in the lung. A series of novel compounds with highly efficient inhibiting the expression of inflammatory factors were designed by using 4-indolyl-2-aminopyrimidine as the core skeleton. Totally eleven 4-indolyl-2-arylaminopyrimidine derivatives were designed and synthesized. As well, the related anti-ALI activity of these compounds was evaluated
急性肺损伤/急性呼吸窘迫综合征(ALI/ARDS)作为临床高死亡率疾病,至今仍未得到有效治疗,抗急性肺损伤药物的研发迫在眉睫。通过抑制炎症级联并减少肺部炎症反应,可以有效治疗急性肺损伤。以4-吲哚基-2-氨基嘧啶为核心骨架,设计了一系列高效抑制炎症因子表达的新型化合物。共设计合成了11种4-吲哚基-2-芳基氨基嘧啶衍生物。同样,评估了这些化合物的相关抗ALI 活性。化合物6c和6h在这些化合物中表现出优异的活性,IL-6和IL-8释放的抑制率分别为62%至77%和65%至72%。此外,大多数化合物在体外没有明显的细胞毒性。在ALI小鼠模型中使用化合物6h (20 mg/kg)可显着减少炎症细胞向肺组织的浸润,达到保护肺组织和改善ALI的作用。此外,化合物6h通过抑制MAPK信号通路中p-38和ERK的磷酸化,抑制炎症反应,对ALI产生保护作用。这些数据表明化合物6h在体外显示出良好的抗炎活性和体内,有望成为治疗
