Biological Activity
IC50: 5 nM (CTX-M-15), 8 nM (TEM-1)[1]
Avibactam is a molecule with little antibacterial activity, that inhibits class A and C β-lactamases, but not metallo types and Acinetobacter OXA carbapenemases[2].
Ceftazidime (HY-B0593)-Avibactam (0-256 mg/L) inhibits 16 blaKPC-2 positive and 1 of blaOXA-232 positive Klebsiella pneumonia growth with MIC50 and MIC90 for both 8?mg/L[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Avibactam (64 mg/kg; s.c.; once) shows mean estimated half-life in plasma in the terminal phase of 0.24 h in Pseudomonas aeruginosa infected neutropenic mice with lung infection[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Six-week-old BALB/c mice (female), K. pneumoniae strain Y8 infection model[4]
-
Dosage:0.375 mg/g in combination with Ceftazidime
-
Administration:Subcutaneous injection, 4 h post infection and given every 8 h for 10 days
-
Result:70% of infection group mice died within 4 days, and all mice in the PBS group died within 13 days. All treatment group mice survived at 10 days post infection with the antibiotic applied every 8 h, whereas 100% of mice in this group died within 4 days after the antibiotic treatment stopped. The spleen and liver of treatment group mice showed lower CFU counts, as compare with that of infected group.
