A new and promising group of antibacterial agents, collectively known as the oxazolidinones and exemplified by linezolid (PNU-100766, marketed as Zyvox), have recently emerged as important new therapeutic agents for the treatment of infections caused by Gram-positive bacteria. Because of their significance, extensive synthetic investigations into the structure-activity relationships of the oxazolidinones
最近出现了一组新的有希望的抗菌剂,统称为恶唑烷酮,以利奈唑胺为例(PNU-100766,以Zyvox出售),最近已成为治疗革兰氏阳性细菌感染的重要新治疗剂。由于它们的重要性,已经在Pharmacia对恶唑烷酮的结构-活性关系进行了广泛的合成研究。这项研究工作的一个方面集中在确定通常的恶唑烷酮A环的生物等效替代物上。在本文中,我们描述了导致鉴定结合了新型异恶唑啉A环替代物的抗菌剂的研究。结果令人满意 发现最初制备的异恶唑啉类似物的体外抗菌活性接近相应的恶唑烷酮祖细胞。将介绍初步系列的异恶唑啉类似物在其B环和C环之间掺入CC或NC键的合成和抗菌活性。许多类似物表现出令人感兴趣的抗菌活性水平。哌嗪衍生物54表现出与利奈唑胺的活性和功效相当的特别有希望的体外活性和体内功效。许多类似物表现出令人感兴趣的抗菌活性水平。哌嗪衍生物54显示出与利奈唑胺的活性和功效相当的特别有希望的体外活性和体内功效。许多
