novel acetamine phenyl pleuromutilin derivatives incorporating 2-aminothiophenol moieties into the C14 side chain were synthesized via acylation reactions under mild conditions. The in vitro antibacterial activities of the synthesized derivatives against three Staphylococcus aureus (MRSA ATCC 43300, ATCC 29213 and AD 3) and two Escherichia coli (ATCC 25922 and 9–1) were evaluated by the broth dilution
通过在温和条件下的酰化反应,合成了一系列将2-氨基硫酚部分结合到C14侧链中的新的乙胺基苯基截短侧耳素衍生物。在体外对三个合成衍生物的抗菌活性的金黄色葡萄球菌(MRSA ATCC 43300,ATCC 29213和AD 3)和两个大肠杆菌(ATCC 25922和9-1)是由肉汤稀释法进行评价。大多数合成的衍生物显示出有效的活性。发现化合物27是针对MRSA的最具活性的抗菌衍生物(最小抑制浓度= 0.015μg/ mL),这可能会导致有希望的抗菌药物。此外,化合物27在体外时间杀灭研究中显示出比头孢菌素更快速的杀菌动力学,并且在抗MRSA方面比头孢菌素具有更长的PAE。然后测量化合物27的PK性质。化合物27的半衰期(t 1/2),清除率(Cl)和血浆浓度-时间曲线下面积(AUC 0→∞)为6.88 h,21.64 L / h / kg和0.48μgh / mL , 分别。在体内化合物的抗菌
