In order to study the effect of heterocyclic carboxamide group on pleuromutilins antibacterial activity, seven novel pleuromutilin derivatives with modified 7-aminocephalosporin acid and thioether moiety were designed and synthesized. The antibacterial activities of the new compounds were tested via agar-well diffusion method in vitro under different concentrations. The results showed that three target compounds (5a, 5d, 5f) still had antibacterial activity against Staphylococcus aureus SC and Staphylococcus aureus ATCC26112 at the concentration 2.0 μg/ mL.
为了研究杂环羧酰胺基团对胸腺嘧啶抗菌活性的影响,研究人员设计并合成了 7 种新型胸腺嘧啶衍生物,这些衍生物具有改性的 7-氨基头孢啉酸和硫醚分子。通过琼脂-孔扩散法对新化合物在不同浓度下的抗菌活性进行了体外测试。结果表明,当浓度为 2.0 μg/ mL 时,三个目标化合物(5a、5d、5f)对金黄色葡萄球菌 SC 和金黄色葡萄球菌 ATCC26112 仍具有抗菌活性。
