BLI-489
Based on 1 Customer Validation
BLI-489 is a Beta-lactamase inhibitor. BLI-489 is an antibacterial adjuvant that significantly enhances the antibacterial efficacy of β-lactam antibiotics. BLI-489 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 can be used for research on bacterial infections.

In Vitro
BLI-489 (2-4 μg/mL; 18-22 h) enhances the antibacterial activity of Piperacillin (HY-B1923) against various predicted panels of Gram-negative and Gram-positive bacteria and clinical isolates[1].
BLI-489 (up to 64 µg/mL; 24 h) 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) 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) exhibits synergistic antibacterial activity with Imipenem (HY-B1369A) in CRAb strains producing CHDLs and MBLs[2].
BLI-489 (8 mg/L; 6-24 h) 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].
BLI-489 (4-64 μg/mL; 4 h) exhibits low hemolytic activity and high biocompatibility in red blood cells (RBCs)[4].

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) 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) 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.

Research Protocol for Infectious Diseases
Infectious-disease experiments test how pathogens interact with host barriers, innate immune receptors, inflammatory signaling, pathogen replication, and tissue injury; pattern-recognition receptors such as TLRs, RIG-I-like receptors, NOD-like receptors, and inflammasomes detect microbial molecules and activate NF-κB, interferon, and cytokine responses. The central hypothesis is that infection severity reflects the balance between pathogen burden and host response: protective inflammation restricts pathogen growth, whereas excessive or mislocalized inflammation contributes to tissue damage and disease phenotype. Unresolved questions include which host pathways are protective versus pathogenic, why some infection models fail to translate to human disease, and which combined readouts best predict clinically relevant infection outcomes.
