背景说明 |
是一种半合成的β-内酰胺类抗生素,对大多数需氧革兰氏阴性菌具有一定的抗菌活性。 |
生物活性 |
Temocillin Disodium Salt 是一种 6-α-甲氧基青霉素,具有抗菌活性。[1-2] |
In Vitro |
Temocillin Disodium Salt inhibited 90% of strains of Escherichia coli,Klebsiella pneumoniae,Citrobacter,Proteus,Providencia,Salmonella,and Shigella at a concentration of less than or equal to 16 micrograms/ml.[1] MICs of Temocillin Disodium Salt and imipenem were 4/8 and 0.5/0.5 mg/L,for CFT073-RR and CFT073-RR Tc,respectively.[2] |
In Vivo |
Temocillin Disodium Salt(200 mg/kg every 2 h,mice)was bactericidal and against CFT073-RR and CFT073-RR Tc without selecting resistant mutants. Temocillin Disodium Salt(200 mg/kg every 4 h)remained active,generating an fT>MIC of 41% and 35%.[2] |
