A series of novel pleuromutilin derivatives containing aryl urea groups was synthesized and their antibacterial
activities were evaluated in vitro against S. aureus ATCC 26113, S.aureus SC, S. albus ATCC 8799 and P. aeruginosa
ATCC 27853. Most of compounds exhibited more potent activities than reference drug tiamulin against S. aureus ATCC
26113 and S. aureus SC. Especially, compounds 12f and 12h containing pyridyl urea group and compound 12j with
quinolinyl urea group showed excellent activity with the MIC value less than 0.001μg/ml against S. aureus SC.

生物,并在体外评估了它们对
金黄色葡萄球菌 A
TCC 26113、
金黄色葡萄球菌 SC、白葡菌 A
TCC 8799 和绿脓杆菌 A
TCC 27853 的抗菌活性。与参考药物替莫林相比,大多数化合物对
金黄色葡萄球菌 A
TCC 26113 和
金黄色葡萄球菌 SC 的活性更强。特别是含有
吡啶基
脲基的化合物 12f 和 12h,以及含有
喹啉基
脲基的化合物 12j,对
金黄色葡萄球菌 SC 的 MIC 值小于 0.001μg/ml,显示出极强的活性。
