The present invention relates to novel derivatives of oxazolidinone, a method thereof and pharmaceutical compositions comprising the derivatives for use in an antibiotic. The oxazolidinone derivatives of the present invention show inhibitory activity against a broad spectrum of bacteria and lower toxicity. The prodrugs, prepared by reacting the compound having hydroxyl group with amino acid or phosphate, have an excellent efficiency on solubility thereof against water. Further, the derivatives of the present invention may exert potent antibacterial activity versus various human and animal pathogens, including Gram-positive bacteria such as Staphylococi, Enterococci and Streptococi, anaerobic microorganisms such as
Bacteroides
and Clostridia, and acid-resistant microorganisms such as
Mycobacterium tuberculosis
and
Mycobacterium avium
. Accordingly, the compositions comprising the oxazolidinone are used in an antibiotic.
本发明涉及一种新型的噁唑烷酮衍生物及其制备方法和制备的药物组合物,用作抗生素。本发明的噁唑烷酮衍生物显示出对广谱细菌的抑制活性,毒性较低。通过将具有羟基的化合物与氨基酸或磷酸反应制备的前药,在溶解度方面具有优异的效率。此外,本发明的衍生物可以对各种人类和动物病原体产生强效的抗菌活性,包括革兰氏阳性菌,如葡萄球菌、肠球菌和链球菌,厌氧微生物,如拟杆菌和梭菌,以及耐酸微生物,如结核分枝杆菌和非结核分枝杆菌。因此,包含噁唑烷酮的组合物可以用作抗生素。
