Abstract A novel series of thieno[2,3-b]pyridines was prepared via an one-step protocol in excellent yields. The protocol involved the reaction of pyridine-2(1H)-thiones with the appropriate halogen containing reagents in ethanolic sodium ethoxide solution under stirring at 80 °C for 2 h. The new thienopyridines were screened against different bacterial and fungal strains. Thieno[2,3-b]pyridine-2-carboxylate
摘要 通过一步法制备了一系列新型噻吩并[2,3-b]吡啶,收率极佳。该协议涉及吡啶-2(1H)-硫酮与适当的含卤素试剂在乙醇钠乙醇溶液中在 80°C 下搅拌 2 小时的反应。针对不同的细菌和真菌菌株筛选了新的噻吩并吡啶。与环丙沙星相比,噻吩并 [2,3-b] 吡啶-2-羧酸盐 9a 对金黄色葡萄球菌和大肠杆菌显示出最有效的抗菌活性,MIC/MBC 值分别为 9.9/19.8 和 19.8/39.5 µM。与庆大霉素相比,9a 是对 MRSA 最有效的化合物,其抑菌圈为 16.2 ± 0.6 mm。此外,9a 对 HEPG2 和 MCF-7 细胞系中的每一个都表现出最佳的细胞毒活性,IC50 值为 25。与多柔比星相比,分别为 7 和 30.53 µM。进行计算机内研究以预测新的噻吩并吡啶作为 pim-1 激酶的潜在抑制剂的能力。图形概要
