BLI-489 hydrate
Based on 1 Customer Validation
BLI-489 hydrate is a Beta-lactamase inhibitor. BLI-489 hydrate is an antibacterial adjuvant that significantly enhances the antibacterial efficacy of β-lactam antibiotics. BLI-489 hydrate blocks the hydrolytic activity of the enzyme by forming a stable intermediate in serine Beta-lactamase, or by coordinating with the binuclear Zn2+ through an oxygen atom in metallo-Beta-lactamase. BLI-489 hydrate can be used for research on bacterial infections.

In Vitro
BLI-489 (up to 64 µg/mL; 24 h) hydrate exhibits synergistic growth inhibition with Ceftriaxone (HY-B0712) in NDM-producing NDM-Kp, with an MIC of 8 μg/mL and an MBC of 16 μg/mL[4].
BLI-489 (4-16 μg/mL; 4-24 h) hydrate inhibits biofilm formation in NDM-Kp, does not cause bacterial cell membrane protein leakage, reduces bacterial load, and maintains the integrity of cell surface morphology[4].
BLI-489 (8 mg/L; 24 h) hydrate exhibits synergistic antibacterial activity with Imipenem (HY-B1369A) in CRAb strains producing CHDLs and MBLs[2].
BLI-489 (8 mg/L; 6-24 h) hydrate in combination with Imipenem shows synergy against OXA-24-like, OXA-51-like, and OXA-58-producing CRAb isolates, but does not show synergy against OXA-23-producing CRAb isolates after 24 h[2].

-
Cell Line:NDM-producing Klebsiella pneumoniae
-
Concentration:4 μg/mL, 8 μg/mL
-
Incubation Time:24 h
-
Result:Significantly reduced the number of bacterial colonies within 24 hours and continuously inhibited the regrowth of the bacteria in combination with Ceftriaxone.
In Vivo
BLI-489 (ED50 dose in combination with Piperacillin ranges from 8.5-69 mg/kg; s.c.; administered at 30 min and 150 min post-infection, 1-2 doses total; observed for 7 days after the first day of dosing) hydrate significantly improves survival rates and restores the in vivo efficacy of Piperacillin in CD-1 mouse acute lethal systemic infection models caused by various β-lactamase-producing pathogenic bacteria[3].
BLI-489 (8 mg/L; administered in agar medium; single administration; 24 h) hydrate synergizes with Imipenem to improve nematode survival in the CRAb-infected C. elegans model[2].

-
Animal Model:BALB/c (female, 6-7 weeks old, 20-25 g)[2]
-
Dosage:25 mg/kg (alone); 25 mg/kg (combination with Imipenem 25 mg/kg)
-
Administration:i.p.; every 8 h; 3 days
-
Result:Rescued 76.7% of mice from CRAb pneumonia in combination with Imipenem.
BLI-489 alone resulted in significantly higher activity against AbTVGH-908 than Imipenem alone.
