    • A compound represented by the following formula (I) is disclosed. This compound has potent antimicrobial activity against a wide spectrum of bacteria from Gram-positive bacteria to Grame-negative bacteria including &bgr;-lactamase producing bacteria. In particular, it has higher antimicrobial activity against methicilline-resistant Staphylococcus aureus (MRSA), penicillin-resistant Streptococcus pneumoniae (PRSP), and imipenem-resistant Pseudomonas aeruginosa than the existing onium salt type cephem derivatives and hence is very useful as a therapeutic agent for infectious diseases derived from various pathogenic bacteria. wherein X represents CH or N, R1 represents a hydrogen atom, substituted or unsubstituted C1-6 alkyl, C2-6 alkenyl, C2-6 alkynyl, or cycloalkyl; any one of R2, R3, R4, and R5 represents R6R7NSO2NH—C1-6 alkyl where R6 and R7, which may be the same or different, represent a hydrogen atom or C1-6 alkyl; and n is 0 or 1.
    • 公开了由下式(I)表示的化合物。 该化合物对革兰氏阳性菌对包括β-内酰胺酶生产细菌在内的Grame-negative细菌的广谱细菌具有有效的抗菌活性。 具体而言,与现有的鎓盐型头孢烯衍生物相比,耐甲氧西林金黄色葡萄球菌(MRSA),青霉素耐药性肺炎链球菌(PRSP)和亚胺培南耐药铜绿假单胞菌具有较高的抗菌活性,因此作为治疗剂非常有用 用于衍生自各种病原菌的感染性疾病,其中X表示CH或N,R 1表示氢原子,取代或未取代的C 1-6烷基,C 2-6烯基,C 2-6炔基或环烷基; R2,R3,R4和R5中的任一个表示R6R7NSO2NH-C1-6烷基,其中R6和R7可以相同或不同,表示氢原子或C1-6烷基; n为0或1。
