    • The present invention relates to novel cephalosporin derivatives, processes for preparing thereof, compositions for preventing and/or treating infectious diseases which comprise the novel cephalosporin derivatives as active components, and the intermediate compounds in the synthesis of cephalosporin derivatives and processes for producing thereof.The present invention is based on the selection of groups containing a condensed heterocyclic ring, particularly a triazolopyrimidine ring or a thiadiazolopyrimidine ring, as substituents at the 3-position of the cephem skeleton, and of groups containing a catechol moiety, particularly a catechol carboxymethyloxyimino moiety or a catechol carboxyimino moiety, as substituents at the 7-position of the cephem skeleton.The compounds of the present invention containing the aforementioned substituents have a strong antibacterial activity against Gram-negative bacteria and also against Gram-positive bacteria including methicillin-resistant Staphylococcus aureus. These compounds are extremely useful for the treatment of infectious diseases.
    • 本发明涉及新型头孢菌素衍生物,其制备方法,用于预防和/或治疗包含新型头孢菌素衍生物作为活性成分的感染性疾病的组合物,以及头孢菌素衍生物的合成中的中间体化合物及其制备方法。 本发明基于选择含有缩合杂环,特别是三唑并嘧啶环或噻二唑并嘧啶环作为头孢烯骨架3位上的取代基的基团,以及含有儿茶酚部分,特别是儿茶酚羧甲氧基亚氨基部分的基团 或邻苯二酚羧基亚氨基部分作为头孢烯骨架的7-位上的取代基。 含有上述取代基的本发明化合物对革兰氏阴性菌具有很强的抗菌活性,对抗耐甲氧西林金黄色葡萄球菌的革兰氏阳性菌具有很强的抗菌活性。 这些化合物对治疗感染性疾病非常有用。
