ME1071

ME1071 is a metallo-β-lactamase inhibitor. ME1071 inhibits IMP-1, VIM-2, and NDM-1 by blocking the entry of β-lactam compounds through zinc binding. ME1071 exhibits competitive inhibition against IMP-1 and VIM-2, and its activity against IMP-type enzymes is superior to that against NDM/VIM-type enzymes. ME1071 can be used in research on multidrug-resistant Gram-negative bacterial infections.

Bacterial Infection

ME1071 reduces the carbapenem MICs of NDM-1-producing Enterobacteriaceae and Acinetobacter strains, but its synergistic effect is weaker than that in IMP- and VIM-producing bacteria^[1].
ME1071 (32 μg/mL; 16-18 h) increases the susceptibility of MBL-producing Pseudomonas aeruginosa (including IMP-1- and VIM-2-producing strains) to Ceftazidime (HY-B0593) and carbapenems and reduces their resistance, but has no significant effect on Piperacillin (HY-B1923) or Aztreonam (HY-B0129)^[2].
ME1071 (32 mg/L; 18 h) enhances the effect of Biapenem (HY-13573) against IMP-type MBL-producing Pseudomonas aeruginosa isolates^[5].

Others

ME1071 exhibits lower binding affinity for NDM-1 than for IMP-1 and VIM-2^[1].
ME1071 inhibits purified IMP-1 with a K_i of 0.41 μM and VIM-2 with a K_i of 120 μM in the nitrocefin hydrolysis assay^[2].

Innate Immunity

ME1071 (100 mg/kg; intraperitoneal injection; twice daily; 7 days), in combination with Biapenem, reduces pulmonary bacterial burden and inflammation and prolongs survival in a mouse VAP model caused by MBL-producing Pseudomonas aeruginosa^[5].

Animal Model:

ddY (male, specific pathogen-free, 6 weeks old, 30-35 g)^[5]
Dosage:

100 mg/kg
Administration:

i.p.; every 12 h; 7 days; beginning 12 h after inoculation
Result:

Combination with Biapenem prolonged survival over 7 days compared with control and Biapenem alone.
Survival was not affected by single-agent administration.
At 30 h post infection, the combination with Biapenem group had 4.40 log₁₀ CFU/mL viable bacteria in lung homogenate (n = 6-7).
Histopathological examination showed only mild inflammatory changes in the combination with Biapenem group.
BALF total cell and neutrophil counts and IL-1β, IL-6, and TNFα levels were decreased in the combination with Biapenem group compared with control and Biapenem groups.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
