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. Many oxazolidinones, including linezolid (marketed as Zyvox), are inhibitors of monoamine oxidase A (MAO-A), which presents an undesired side effect. Recently, it was found that the 1,2,3-triazole is a good replacement
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。许多恶唑烷酮,包括利奈唑胺(以Zyvox销售),都是单胺氧化酶A(MAO-A)的抑制剂,具有不良的副作用。最近,发现1,2,3-三唑是恶唑烷酮中常规乙酰胺官能团的良好替代品。我们现在公开的发现是,在4位上带有取代基(如甲基,小取代的甲基,溴或线性(sp杂化)基团)的1,2,3-三唑(化合物如5、16、19和21 )是在检测限内对MAO-A活性降低或没有活性的良好抗菌剂。该结果对于开发具有改善的安全性的恶唑烷酮特别有希望。可以在对接至MAO-A / MAO-B同源性模型的基础上合理化MAO-A SAR。
