properties of conformationally constrained analogues in which the morpholine ring of linezolid is replaced with various substituted azabicyclo[3.1.0]hexyl ring systems. Several classes of azabicyclic analogues were identified with activity comparable or superior to that of linezolid. These include analogues bearing hydroxyl, amino, amido, or carboxyl groups on the azabicyclic ring. The azabicyclic acid analogue
恶唑烷酮是一类新型的合成抗菌素,可有效对抗多种致病性革兰氏阳性细菌,包括具有多重耐药性的菌株。利奈唑胺是该类别中第一个进入市场的药物,已成为治疗严重感染的重要新选择,尤其是对耐甲氧西林的金黄色葡萄球菌(MRSA)和耐万古霉素的粪肠球菌(VRE)引起的严重感染。在寻找具有改进的效力和光谱的新型恶唑烷酮中,我们制备并评估了构象约束类似物的抗菌性能,其中利奈唑胺的吗啉环被各种取代的氮杂双环[3.1.0]己基环系统取代。鉴定出几类具有与利奈唑胺相当或更好的活性的氮杂双环类似物。这些包括在氮杂双环上带有羟基,氨基,酰胺基或羧基的类似物。氮杂双环酸类似物50对特定革兰氏阳性和顽固革兰氏阴性病原体(金黄色葡萄球菌,肺炎链球菌和粪肠球菌MICs <或= 1 microg / mL;流感嗜血杆菌MIC = 4 microg)的效力是利奈唑胺的4倍。 / mL)。
