头孢美唑钠 是一种具有广谱抗菌活性的半合成头孢霉素抗生素 (antibiotic)。Cefmetazole sodium 通过与青霉素结合蛋白 (PBPs) 结合，阻止肽聚糖的交联，导致细胞壁完整性的丧失。Cefmetazole sodium 用于妇科、腹腔内、尿道、呼吸道和皮肤和软组织感染的研究。 application： Cefmetazole is used to study the effect of expression, binding, and inhibition of penicillin-binding proteins (with the exception of PBP2) on bacterial cell wall mucopeptide synthesis. It is also used to study protein mediated antibiotic transport. product description： Cefmetazole sodium (Sodium cefmetazole) is a semisynthetic cephamycin antibiotic with broad-spectrum antibacterial activity. Cefmetazole sodium results in the loss of cell wall integrity by binding to penicillin-binding proteins (PBPs) and preventing the crosslinking of peptidoglycan. Cefmetazole sodium is used for the research of gynecologic, intraabdominal, urinary tract, respiratory tract, and skin and soft tissue infections
