Cefepime chloride
Based on 16 publication(s) in Google Scholar
Cefepime (BMY-28142) chloride is a broad-spectrum, blood-brain barrier-permeable cephalosporin antibiotic with hPON1 inhibitory activity, with an IC50 of 21.115 mM and a Ki of 35.092 mM. Cefepime chloride inhibits hPON1 via a non-competitive mechanism and blocks GABAA receptors. Cefepime chloride penetrates the outer membrane of Gram-negative bacteria, inhibits the growth of Gram-positive and Gram-negative bacteria, and does not induce the production of β-lactamase.

Cefepime (18 h) chloride potently inhibits most isolates of Gram-negative aerobic bacteria. Among these pathogens, the MIC90 value is ≤1 mg/L for most Enterobacteriaceae, 16 mg/L for Pseudomonas aeruginosa, and ≤0.12 mg/L for Haemophilus influenzae, Neisseria gonorrhoeae and Branhamella catarrhalis[4].
Cefepime (18-48 h) chloride inhibits Gram-positive bacterial isolates, with an MIC90 value of ≤ 4 mg/L against staphylococci and an MIC90 value of ≤ 0.25 mg/L against most streptococci, but shows limited activity against Enterococcus faecalis, Listeria monocytogenes and Bacteroides species[4].
Cefepime chloride exhibits stable in vitro activity across different culture media, pH values, and inoculum sizes. For most isolates, the difference between its MIC and MBC values is extremely small, but the MBC values of Pseudomonas aeruginosa and Staphylococcus aureus in human serum are higher[4].
Cefepime (2-8×MIC; 2-24 h) chloride exhibits concentration-dependent bactericidal activity against Enterobacter cloacae (with the strongest activity and no regrowth observed at 8×MIC), sustained bactericidal activity against Pseudomonas aeruginosa, but only limited transient activity against Methicillin (HY-121544)-resistant Staphylococcus aureus[4].
Cefepime (1 mM) chloride exhibits high stability against almost all tested plasmid-mediated and chromosome-mediated bacterial β-lactamases, and is only slightly hydrolyzed by the PSE-2 enzyme[4].
Cefepime chloride is a weak inhibitor of most bacterial β-lactamases, exhibiting only weak activity against Proteus vulgaris Ic enzyme and Pseudomonas aeruginosa Id enzyme, with an IC50 value of > 400 mg/L against the key clinical β-lactamases TEM-1 and P99[4].
Cefepime chloride exhibited only marginal differences in MIC values among Escherichia colipermeability mutants, whereas an 8-fold difference was observed among Pseudomonas aeruginosapermeability mutants, indicating that its ability to enhance bacterial cell wall penetration is limited[4].

Cefepime (250-500 mg/kg; intravenous bolus) chloride does not increase the susceptibility to pentylenetetrazol (PTZ)-induced convulsions in normal male ICR mice[3].
Cefepime (250-500 mg/kg; intravenous bolus) chloride significantly increases the average seizure grade to 3.3 in the low-current electroshock-induced seizure model of normal male ICR mice, while the 250 mg/kg dose increases the average seizure grade to 2.0[3].
Cefepime (500 mg/kg; intravenous bolus) chloride induces convulsions in 2 out of 3 normal male ICR mice, and elicits electroencephalogram spike waves in the parietal cortex of 1 mouse following low-current electroshock stimulation[3].
Cefepime (500 mg/kg; intravenous bolus) chloride significantly increases the average seizure grade induced by low-current electroconvulsive shock to 4.0 in cornea-kindled male ICR mice[3].

Result:Significantly prolonged the half-life of cefepime and all mice survived at 18-22 mg/kg cisplatin, and when pretreatment with 26 mg/kg cisplatin significantly decreased survival with the half-life of cefepime was not significantly longer than of 18 mg/kg cisplatin.
