應(yīng)用領(lǐng)域
用途一
為半合成廣譜頭孢菌素,抗菌機(jī)理、抗菌譜、適應(yīng)性均與頭孢噻吩相似用途二
半合成廣譜頭孢菌素??咕鷻C(jī)理、抗菌譜、適應(yīng)癥均與頭孢噻吩相似。對革蘭氏性菌弱于后者。但對革蘭氏陰性菌比后者強(qiáng)得多,尤其對肺炎桿菌有效,對大腸桿菌比頭孢噻吩強(qiáng),對肺炎球菌作用僅次于青霉素而優(yōu)于其他抗生素。血清蛋白結(jié)合率74-86%。在肝、腎、心、脾、肺、肌肉等組織中濃度高。用于上述器官敏感菌感染。特別是用于一些嚴(yán)重感染。臨床治療呼吸系統(tǒng)及泌尿系感染療效顯著。常見問題列表
生物活性
Cefazolin是一種半合成的頭孢菌素,具有廣譜的抗菌作用,抑制細(xì)菌細(xì)胞壁的合成。它可達(dá)到高血清水平,通過尿液快速排泄。靶點(diǎn)

體外研究
Cefazolin (50-300 μg/mL; 6 or 24 hours) has a direct anti-inflammatory effect on C8-B4 cells stimulated by LPS (1 μg/mL).
Cell Viability Assay
Cell Line: | Mouse C8-B4 microglial cells |
Concentration: | 50, 100, 150, 200, 250, and 300 μg/mL |
Incubation Time: | 6 or 24 hours |
Result: |
Inhibited proinflammatory cytokine production.
Inhibited IL-6 production at 50 and 100 μg/mL. |
體內(nèi)研究
Cefazolin (300 mg/kg; injected intraperitoneally 1 h before surgery and then once per day for 5 days after surgery) can attenuate surgery-induced post-operative memory and learning impairment in mice. Cefazolin alone may induce cognitive dysfunction possibly by transient gut dysbiosis in mice without surgery.
Animal Model: | Six- to 8-week-old CD-1 male mice (weighing 31-36 g) |
Dosage: | 300-500 mg/kg |
Administration: | 10 mg in 0.1 mL was intraperitoneally injected 30 min before surgery and then once every day for 5 days. |
Result: | Improved learning and memory after surgery and might impair learning and memory in mice without surgery. |
