用途: Nafcillin sodium monohydrate is a semi-synthetic antibiotic related to penicillin.Target: AntibacterialNafcillin sodium is a narrow-spectrum, beta-lactam antibiotic of the penicillin class. As a beta-lactamase-resistant penicillin, it is used to treat infections caused by Gram-positive bacteria, in particular, species of staphylococci that are resistant to other penicillins. Nafcillin is considered therapeutically equivalent to oxacillin, although its safety profile is somewhat different. Nafcillin was shown to reversibly inhibit beta-lactamase from Staphylococcus aureus PC1 with characteristics indicative of a type A inhibitor [Citri, Samuni & Zyk (1976) Proc. Natl. Acad. Sci. U.S.A. 73, 1048-1052]. At nafcillin concentrations above 80 mM, complete inactivation occurred within 200 s. Upon removal of the excess nafcillin the inhibited enzyme was re-activated completely, with a rate constant of 2.0 x 10(-3) s-1 (25 degrees C) [1, 2]. 物理化学性质: CAS号:7177-50-6 常用中文名:萘夫西林钠 常用英文名:Nafcillin sodium salt monohydrate 分子式:C21H23N2NaO6S 分子量:454.472 密度:1.42 g/cm3 沸点:714.1ºC at 760 mmHg 熔点:N/A 闪点:385.7ºC 储存条件:2-8°C |
