Oxazolidinones represent a new and promising class of antibacterial agents. Current research in this area is mainly concentrated on improving the safety profile and the antibacterial spectrum. Oxazolidinones bearing a (pyridin-3-yl)phenyl moiety (e.g., 3) generally show improved antibacterial activity compared to linezolid but suffer from potent monoamine oxidase A (MAO-A) inhibition and low solubility
恶唑烷酮代表一类新的有希望的抗菌剂。目前在该领域的研究主要集中在改善安全性和抗菌谱上。与利奈唑胺相比,带有(吡啶-3-基)苯基部分(例如3)的恶唑烷酮通常显示出改善的抗菌活性,但是具有有效的单胺氧化酶A(MAO-A)抑制作用和低溶解度。我们现在公开的发现是,在吡啶基部分上具有无环取代基的3的新类似物对革兰氏阳性病原体(包括耐利奈唑胺的肺炎链球菌)表现出优异的活性。通常,相对于未取代的化合物3,更大的取代基产生的MAO-A抑制作用显着降低。可以使用MAO-A / MAO-B同源模型在对接研究的基础上合理化MAO-A SAR。极性基团的引入增加了溶解度。一种优化的类似物化合物13在大鼠中显示出低清除率,并且在小鼠肺炎模型中抗肺炎链球菌的功效。
