生物活性 | Ertapenem (MK-0826) is a broad spectrum and long acting β-lactamantibiotic. Ertapenem has a broad-spectrum anti-anaerobic activity against a variety of anaerobes with a modeMICof 0.12 μg/mL. Ertapenem can be used for the research of severe infections caused by bacteria in the skin, lungs, stomach, pelvis, and urinary tract[1][2]. |

体内研究 (In Vivo) | Ertapenem (Subcutaneous injection, 0-10 mg/kg, 0-120 h after infection,S. aureusthigh tissue infection model) shows >3 log10CFU reduction of organism at 10 mg/kg, and maintains the activity with 3.3 and 4.4 log10CFU eliminated at 2 mg/kg[2].Ertapenem (Subcutaneous injection, 4h after infection, systemic infection model) is active against all gram-positive organisms, and is also active against gram-negative organisms tested with ED50s of<0.25 mg/kg/dose[2].
Animal Model: | S. aureusthigh tissue infection model (DBA/2 mice)[2] | Dosage: | 0.5,1, 2, 5, 10 mg/kg (given at 2, 6, 10, 24, 48, 72, 96, 120 h) | Administration: | Subcutaneous injection (0.5 mL after infection) | Result: | Displayed >3 log10CFU reduction of organism compared to non-antibiotic-treated controls at 10 mg/kg.Maintained the activity with 3.3 and 4.4 log10CFU eliminated at 2 mg/kg. |
Animal Model: | Systemic infection model (DBA/2 female mice, viral antibody-free CD-1 female mice)[2] | Dosage: | 0-3 mg/kg approximately | Administration: | Subcutaneous injection (0.5 mL, begin immediately and 4 h after infection) | Result: | Showed activity against all gram-positive organisms, and also ram-negative organisms tested with ED50s of<0.25 mg/kg/dose. |
Animal Model: | CD-1 mice, rats[2] | Dosage: | 10 mg/kg approximately | Administration: | Intraperitoneal injection (pharmacokinetic assay) | Result: | Exhibited an AUC0-∞ranging from 1.8-21.82 μgohr/mL in tissue in mice following a 10-mg/kg i.p. dose.Exhibited slow clearance rate with a t1/2βof 3.2 h, Clp of 0.47 mL/min/kg, AUC0-8of 284.15μgohr/mL. |
