respectively. Furthermore, all the new compounds were tested for PDE4 inhibitory activity and 5j showed relatively good inhibitory activity towards PDE4 with inhibition of 50.9 % at 10 μm. In silico analysis demonstrated the favorable interaction of the title compounds with the target enzyme. Taken together, the present study introduces a new scaffold for the development of novel PDE4 inhibitors to fight
磷酸二酯酶 4 (PDE4) 是参与环磷酸腺苷 (cAMP) 水解的关键酶,在多种癌症中广泛表达。PDE4 的抑制导致细胞内 cAMP 水平的浓度增加,从而在靶细胞中产生抗炎反应。在本报告中,使用绿色方案(TBAB 在回流水中)合成了两个系列的三唑并吡啶二腈和取代的二氢吡啶二腈。我们接下来评估了标题化合物对肺癌 (A549) 细胞的细胞毒性,并鉴定了 7'-[4-(甲基磺酰基)苯基]-5'-oxo-1',5'-二氢螺[环己烷-1,2'- [1,2,4]三唑并[1,5-a]吡啶]-6',8'-二甲腈(5h)和7'-(1-甲基-1H-咪唑-2-基)-5'-氧代‐1',5'-二氢螺[环己烷-1,2'-[1,2,4]三唑并[1,5-a]吡啶]-6',8'-二甲腈 (5j) 作为铅类似物,IC50 值分别为 15.2 和 24.1 μm。此外,测试了所有新化合物的 PDE4 抑制活性,5j 对 PDE4
