Cefoxitin (sodium salt) is a second generation cephalosporin antibiotic that was used to treat a wide range of gram-negative and gram-positive bacteria [1][2].
Cefoxitin, 3-carbamoyloxymethyl-7-a-methoxy-7- [2-(2-thienyl)acetamido]-3-cephem-4-carboxylic acid, is a semisynthetic cephamycin antibiotic with broad-spectrum activity. Cefoxitin is also active in vivo against a wide variety of bacteria including penicillin-resistant staphylococci and effective against gram-negative organisms including strains of indole-positive Proteus [1].
In mice, cefoxitin was more active against the cephalosporin-sensitive gram-negative bacteria, strains of E.coli, indole-producing Proteus, and Serratia, and the lactamase producing 2646. Cefoxitin was degraded by the lactamase of E. cloacae at a much slower rate than are the cephalosporins. In pharmacological studies, cefoxitin was found in sera and detected in urine samples in amounts greater than those of cephalothin and less than those of cephaloridine [1].

DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
