Biological Activity
β-lactamase[1]
Taniborbactam (VNRX-5133) has IC50s of 0.5 nM, 2 nM, 0.5 nM, 0.06 nM for KPC-2, OXA-48, VIM-4 of K.pneumoniae strain and VIM-2 of P.aeruginosa strain[2].
Both cefepime/Taniborbactam (10 μg/mL) and meropenem/Taniborbactam combinations are highly active against all six of the NDM-1-producing clinical isolates from K.pneumoniae and E.coli, with MIC ranges of 16-0.25 and 1-0.125 μg/mL, respectively[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Combination of Cefepime (16 mg/kg) and Taniborbactam (16 mg/kg; s.c.; twice-a-day for 7 days) demonstrates >2 log10 reductions in viable bacterial counts in the kidney of the ascending urinary tract infection model against a CTX-M-15-producing strain of E.coli[2].
Taniborbactam has a T1/2 of 0.16 hours, a CL of 618 mL/h/kg, and a Vss of 143 mL/kg for mice[2].
