Four series of novel pyridine derivatives (17 a–i, 18 a–i, 19 a–e, and 20 a–e) were synthesized and their antimicrobial activities were evaluated. Of all the target compounds, almost half target compounds showed moderate or high antibacterial activity. The 4-F substituted compound 17 d (MIC=0.5 μg/mL) showed the highest antibacterial activity, its activity was twice the positive control compound gatifloxacin
合成了四个系列的新型吡啶衍生物( 17a - i 、 18a - i 、 19a - e和20a - e )并评估了它们的抗菌活性。在所有目标化合物中,几乎一半的目标化合物表现出中等或较高的抗菌活性。 4-F取代的化合物17d (MIC=0.5μg/mL)显示出最高的抗菌活性,其活性是阳性对照化合物加替沙星(MIC=1.0μg/mL)的两倍。对于真菌ATCC 9763,化合物17a和17d的活性与阳性对照化合物氟康唑(MIC=8μg/mL)相当。此外,化合物17a和17d对人LO2细胞几乎没有细胞毒性,并且即使在超高浓度(200μM)下也没有表现出溶血。结果表明这些化合物对于进一步开发抗菌和抗真菌剂具有重要价值。
