A series of novel oxazolidinone antibacterials with diverse fused heteroaryl C-rings bearing hydrogen bond donor and hydrogen bond acceptor functionalities were designed and synthesized. The compound with benzoxazinone C-ring substructure (8c) exhibited superior activity compared to linezolid against a panel of Gram-positive and Gram-negative bacteria. Structural modifications at C5-side chain of 8c
设计并合成了一系列新颖的恶唑烷酮类抗菌剂,它们具有带有氢键供体和氢键受体功能的各种稠合杂芳基C环。与利奈唑胺相比,具有苯并恶嗪酮C环亚结构的化合物(8c)对一组革兰氏阳性和革兰氏阴性细菌表现出更高的活性。8c的C5侧链的结构修饰导致鉴定了几种有效的化合物(12a,12b,12g和12h)。选定的化合物8c和12a显示出非常好的微粒体稳定性,并且没有CYP 450责任,从而消除了初步的安全障碍。的对接模型12A结合23S rRNA的建议的增强的效力12A是由于附加的配体-受体相互作用。
