Cilastatin (200 μg/mL; 24 hours; RPTECs) treatment protects against Vancomycin-induced proximal tubule apoptosis and increases cell viability, without compromising the antimicrobial effect of Vancomycin.
Apoptosis Analysis
| Cell Line: | Renal proximal tubular epithelial cells (RPTECs) |
| Concentration: | 200 μg/mL |
| Incubation Time: | 24 hours |
| Result: | Significantly ameliorated Vancomycin-induced nuclear apoptosis. |
In a mouse model (female mice, strain CD-1, 20 g) of systemic infection, Imipenem plus Cilastatin can protect mice from S. aureus , E. coli , and P. aeruginosa infection.
