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.
本发明涉及噁唑烷酮的新型衍生物、其方法以及包含该衍生物的用于抗生素的药物组合物。本发明的噁唑烷酮衍生物对广谱细菌具有抑制活性,毒性较低。通过使具有羟基的化合物与氨基酸或磷酸盐反应制备的原药在水中的溶解度效率极高。此外,本发明的衍生物可对各种人类和动物病原体发挥强效抗菌活性,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(如乳酸杆菌和梭状芽孢杆菌)以及耐酸微生物(如结核分枝杆菌和鸟疫分枝杆菌)。因此,包含噁唑烷酮的组合物可用于抗生素。
