AM-112
AM-112 is a β-lactamase (β-lactamase) inhibitor and antibacterial agent, with IC50 values ranging from 0.0002 μg/mL to 0.67 μg/mL against class A, C, and D β-lactamase. By inhibiting PBP2, the penicillin-binding protein of E. coli, and protecting Ceftazidime (HY-B0593) from enzymatic hydrolysis, AM-112 significantly enhances the antibacterial efficacy of Ceftazidime against Gram-negative bacteria, enterococci, and staphylococci. AM-112 exhibits favorable pharmacokinetic properties and acid-base stability. AM-112 can be used for the research of bacterial infections.

AM-112 (combined with Ceftazidime at a 2:1 ratio) synergistically reduces the MIC of Ceftazidime (HY-B0593) in all tested Enterococcus faecalis strains, with the greatest MIC reduction observed in E. faecalis SFZ (from 64 μg/mL to 8 μg/mL)[1].
AM-112 (0.5-32 μg/ml; 18-24 h) has an MIC of 2 μg/mL against Methicillin (HY-121544)-susceptible Staphylococcus aureus, an MIC range of 4-16 μg/mL against anaerobic bacteria of the genera Clostridium and Bacteroides, and an MIC of ≥32 μg/mL against Escherichia coli, Pseudomonas, Acinetobacter, Enterococcus and Methicillin-resistant Staphylococcus aureus[2].

-
Cell Line:Multiple bacterial strains including Escherichia coli, Enterobacter cloacae, Enterococcus faecalis, Pseudomonas aeruginosa ATCC 27853 producing Class A or Class C β-lactamases
-
Concentration:10 μg of AM-112 per disk, combined with 30 μg Ceftazidime per disk
-
Incubation Time:overnight incubation at 37℃
-
Result:Enhanced the zone diameter of Ceftazidime against bacterial isolates producing Class A and Class C β-lactamases, while it showed no enhancing effect on the activity of Ceftazidime against Pseudomonas aeruginosa ATCC 27853.
AM-112 (administered intravenously at 1.9-19 mg/kg) exhibits inhibitory effects against E. cloacae P99-induced sepsis in mice, with an ED50 of 19 mg/kg, and significantly enhances the efficacy of Ceftazidime when co-administered[1].
AM-112 (>40 mg/kg; s.c.) shows limited inhibitory effect on K. pneumoniae SHV-5-induced sepsis in mice, with an ED50 >40 mg/kg, but it can enhance the efficacy of Ceftazidime when administered in combination[1].
