Tuberculosis is an ever-evolving infectious disease that urgently needs new drugs. In the search for new antituberculosis agents, a library of 3-cinnamoyl-4-hydroxy-6-methyl-2H-pyran-2-ones (CHPs) (2a–2y) was synthesized and evaluated against a standard virulent laboratory strain of Mycobacterium tuberculosis H37Rv. Out of 25 compounds, 11, 5, 7 and 2 (2a and 2u) showed least, moderate, good and appreciable
结核病是一种不断发展的传染病,迫切需要新的药物。在寻找新的抗结核药物的过程中,合成了一个 3-cinnamoyl-4-hydroxy-6-methyl-2 H -pyran-2-ones (CHP) ( 2a-2y ) 文库,并针对标准的毒性实验室菌株进行了评估。结核分枝杆菌H37Rv。在 25 种化合物中,11种、5种、7种和2种(2a和2u)分别基于最低抑菌浓度 (MIC) 显示出最低、中等、良好和可观的活性。2a和2u的MIC 值为 4 μg ml -1,与标准抗结核药物乙胺丁醇、链霉素和左氧氟沙星接近。2a和2u均未显示出对革兰氏阳性或革兰氏阴性细菌甚至对非结核分枝杆菌即耻垢分枝杆菌的任何活性。因此,与抗结核药物利福平、异烟肼和 pretomanid 一样,它们对结核病具有高度特异性。所有基于吡喃酮的查尔酮在浓度高达 80 μM 时对正常人肾细胞系 (HEK-293) 没有可识别的细胞毒性水平,11
