Summary
Tebipenem pivoxil (L084) is an orally active antibiotic against a variety of pathogenic bacteria . Tebipenem pivoxil binds penicillin-binding protein (PBP), thereby inhibiting cell wall synthesis [1] .
In Vitro
Tebipenem pivoxil (0-128 μg/mL; 18–24 h) displays excellent antibacterial activity against a variety of pathogenic bacteria [1] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Cell Viability Assay [1]
| Cell Line: | Gram-positive and Gram-negative bacteria |
| Concentration: | 0-128 μg/mL |
| Incubation Time: | 18–24 h |
| Result: | Showed inhibition with MIC 50 s below 64 μg/mL against tested Gram-positive and Gram-negative bacteria. |
In Vivo
Tebipenem pivoxil (L084) (0-4.00 g/kg; p.o.; once) shows minimal lethal dosage (MLD) of 4.00 g/kg and the maximum tolerance dosage (MTD) of 3.40 g/kg in mice
[1]
.
Tebipenem pivoxil (50 and 100 mg/kg; p.o.; once) significantly protects the sepsis mice challenged with various pathogenic bacteria
[1]
.

| Animal Model: | KM mice weighing 18–22 g [1] |
| Dosage: | 2.89, 3.40 and 4.00 g/kg |
| Administration: | Oral administration (tablet), once |
| Result: | Within the 14-day observation period, only one mouse was dead in the maximum oral dosage (4.00 g/kg). The minimal lethal dosage (MLD) was 4.00 g/kg and the maximum tolerance dosage (MTD) in the mice was 3.40 g/kg. Showed dose-dependent liver and kidney damage. |
| Animal Model: | ICR mice, sepsis mouse models [1] |
| Dosage: | 50 and 100 mg/kg |
| Administration: | Oral administration (tablet), once |
| Result: | Significantly increased the survival number of the sepsis mice within a 168 h observation period. |
