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.
本发明涉及新型氧唑啉酮衍生物,其方法以及包含这些衍生物的制药组合物,用于抗生素。本发明的氧唑啉酮衍生物显示出对广谱细菌的抑制活性和较低的毒性。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,在其溶解度对水表现出优异效率。此外,本发明的衍生物可能对各种人类和动物病原体发挥强效的抗菌活性,包括革兰氏阳性细菌如葡萄球菌、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分枝杆菌。因此,含有氧唑啉酮的组合物用作抗生素。
