Imipenem is a semisynthetic thienamycin. Imipenem is one of the broad-spectrum antibiotics that has a bactericidal action against multiple gram-negative, gram-positive, aerobic, and anaerobic bacteria by binding to penicillin-binding protein 2 (PBP2) and interacting with bacterial cell wall synthesis[2,5].It exerts a bactericidal effects by disrupting cell wall synthesis.
The MICs for the Y. pestis strains with imipenem ranged from a low of 0.12 mg/liter to a high of 1.0 mg/liter,the highest is 0.5 mg/liter[7].Combination of relebactam with β-lactams led to >128- and 2-fold decreases in the MICs of amoxicillin and imipenem (from 8 to 4 mg/L). In vitro, M. abscessus was not killed by the imipenem/relebactam combination. In contrast, relebactam increased the intracellular activity of imipenem, leading to 88% killing[6]. A high dose of imipenem enhanced the interleukin (IL)-1β level [9] and natural killer (NK) cell activity[3].
Dose-dependent effect of subcutaneous administration of imipenem on the inflammatory responses in sepsis mice. A dose of 25 mg/kg imipenem resulted in better pathology, lower inflammatory mediators, and increased survival rate in sepsis mice[1].

亚胺培南是一种半合成的硫霉素。亚胺培南是一种广谱抗生素，通过与青霉素结合蛋白 2 (PBP2) 结合并与细菌细胞壁合成相互作用，对多种革兰氏阴性菌、革兰氏阳性菌、需氧菌和厌氧菌具有杀菌作用 [2,5].通过破坏细胞壁合成发挥杀菌作用。
鼠疫耶尔森菌株与亚胺培南的 MIC 范围从最低的 0.12 毫克/升到最高的 1.0 毫克/升，最高为 0.5 毫克/升[7]。组合relebactam 和 β-内酰胺导致 >；阿莫西林和亚胺培南的 MIC 分别降低 128 倍和 2 倍（从 8 mg/L 到 4 mg/L）。在体外，亚胺培南/relebactam 组合未杀死脓肿分枝杆菌。相比之下，relebactam 增加了亚胺培南的细胞内活性，导致 88% 的杀灭[6]。高剂量亚胺培南可增强白细胞介素 (IL)-1β 水平[9]和自然杀伤 (NK) 细胞活性[3]。
亚胺培南皮下给药对脓毒症小鼠炎症反应的剂量依赖性影响。 25 mg/kg 亚胺培南的剂量可改善脓毒症小鼠的病理学、降低炎症介质并提高存活率[1]。

THP-1 cells were seeded into 24-well plates, differentiated for 24 h and infected with M. abscessus CIP104536. Imipenem (8 and 32 mg/L) or amoxicillin alone or in combination with relebactam (16 mg/L) or avibactam (16 mg/L) were added to each well. Rifabutin was also studied in combination with imipenem (8 mg/L), imipenem/relebactam or imipenem/avibactam. Imipenem was added every 24 h. |
|
Reaction Conditions |
Imipenem (8 and 32 mg/L) was added every 24 h. |
|
Applications |
Combination of relebactam with β-lactams led to >128- and 2-fold decreases in the MICs of amoxicillin and imipenem (from 8 to 4 mg/L). In vitro, M. abscessus was not killed by the imipenem/relebactam combination. In contrast, relebactam increased the intracellular activity of imipenem, leading to 88% killing. |
| Animal experiment [3]: | |
|
Animal models |
Female C57BL/6 mice (6-8 weeks old, 20-25 g body weight) |
|
Preparation Method |
Mice were randomly divided into four groups: the sham-operated mice as the control group, CLP-induced sepsis mice, CLP-induced sepsis mice treated with the low dose of imipenem (25 mg/kg), CLP-induced sepsis mice treated with the high dose of imipenem (125 mg/kg). Imipenem was injected one hour after sepsis induction, repeating the injection every 24 h up to 72 h. |
|
Dosage form |
25-200 mg/kg imipenem, repeating the injection every 24 h up to 72 h. |
|
Applications |
Sepsis mice treated with a high dose (125 mg/kg) of imipenem showed a significant reduction in bacterial load, while increased liver enzymes, endotoxin level, and inflammatory cytokine production in plasma and liver. Significant reduction in the liver enzymes, bacterial load, endotoxin levels, and inflammatory cytokine levels was observed in the mice treated with a low dose (25 mg/kg) of imipenem. Liver tissue pathology of mice indicated little tissue destruction in the sepsis mice treated with 25 mg/kg of imipenem compared to other groups. Mice receiving 25 mg/kg of imipenem had better survival rate. |
