All obtained compounds were evaluated for their antimycobacterial activity against Mycobacetrium bovis and Mycobacterium tuberculosis at concentrations of 1–100 µg/ml using MABA test. Synthesized nucleosides showed high antimycobacterial activity against M. bovis and M. Tuberculosis. The MIC50 values of 11 and 13 were similar or close to that of the reference drug rifampicin.
我们在此报告了新的 5-取代尿苷衍生物作为结核分枝杆菌的有效抑制剂。在室温下,通过钯催化的 5-碘-6-甲基嘧啶碱与末端乙炔的 Sonogashira 交叉偶联反应合成了一系列新的 5-炔基取代的尿苷衍生物,在 DMF 中具有良好的产率。发现嘧啶环C-6位的甲基对目标化合物的收率没有影响。使用 MABA 测试评估了所有获得的化合物在 1–100 µg/ml 浓度下对牛分枝杆菌和结核分枝杆菌的抗分枝杆菌活性。合成的核苷对牛分枝杆菌和M. 结核病。11 和 13 的 MIC50 值与参考药物利福平的 MIC50 值相似或接近。
