    • The invention provides a method for preventing or treating a disease caused by an extracellular microorganism, said method comprising systemically administering to a subject in need thereof a prophylactically or therapeutically effective amount of a salicylic acid (SAL) or a SAL analog. The extracellular microorganism can be of the bacterial genus Staphylococcus, for example, Staphylococcus aureus. The extracellular microorganism can be a strain that is resistant to at least one antibiotic. The strain can be selected from the group consisting of methycillin-resistant Staphylococcus aureus (MRSA), vancomycin-intermediate Staphylococcus aureus (VISA) and vancomycin-resistant Staphylococcus aureus (VRSA). The invention also provides a method for preventing or treating an infectious disease caused by of methycillin-resistant Staphylococcus aureus (MRSA), vancomycin-intermediate Staphylococcus aureus (VISA) or vancomycin-resistant Staphylococcus aureus (VRSA), comprising systemically co-administering in a synergistic combination to a subject in need thereof prophylactically or therapeutically effective amounts, individually or collectively, of a salicylic acid (SAL) or a SAL analog and at least one additional antimicrobial agent, for example, vancomycin and/or linezolid.
    • 本发明提供了一种预防或治疗由细胞外微生物引起的疾病的方法,所述方法包括向有需要的受试者全身施用预防或治疗有效量的水杨酸(SAL)或SAL类似物。 细胞外微生物可以是细菌属葡萄球菌,例如金黄色葡萄球菌。 细胞外微生物可以是对至少一种抗生素具有抗性的菌株。 该菌株可以选自耐甲氧西林金黄色葡萄球菌(MRSA),万古霉素 - 中间体金黄色葡萄球菌(VISA)和耐万古霉素金黄色葡萄球菌(VRSA)。 本发明还提供一种预防或治疗由耐甲氧西林金黄色葡萄球菌(MRSA),万古霉素中间体金黄色葡萄球菌(VISA)或万古霉素耐药金黄色葡萄球菌(VRSA)引起的感染性疾病的方法,其包括全身共同施用于 对需要其的预防或治疗有效量的水杨酸(SAL)或SAL类似物和至少一种另外的抗微生物剂例如万古霉素和/或利奈唑胺的预防或治疗有效量的协同组合。

    • The present invention relates to levocarrimycin, its pharmaceutical compositions, preparation methods and application. Levocarrimycin is a mixture of isovalerylspiramycin III, II and I as main components and contains some isobutyrylspiramycin III and II, butyrylspiramycin III and II, propionylspiramycin III and II, as well as acetylspiramycin III and II, among which, the content of isovalerylspiramycin III is no less than 30 wt %, the total content of isovalerylspiramycin III, II and I is no less than 60 wt %, and the content of acylspiramycin is 80-98 wt %. Specific optical rotation of said levocarrimycin is [α]D=−52°˜−57° in the solution of 0.02 g/ml chloroform at temperature of 25° C. The present invention also relates to the crystalline compound of isovalerylspiramycin III, II or I in levocarrimycin, and pharmaceutical compositions containing the said levocarrimycin. In present invention, the active components in levocarrimycin or its pharmaceutical compositions have optical activity and excellent anti-infective effect.
