Taniborbactam_product_DataBase

Bioactivity	Taniborbactam (VNRX-5133) is a reversible and selective boronic acid-containing pan-spectrum β-lactamase inhibitor with IC50s of 8-530 nM. Taniborbactam has IC50s of 30 nM, 32 nM, 42 nM, 20 nM for KPC-2, AmpC, OXA-48, and VIM-2. Taniborbactam is against Gram-negative bacteria[1][2].
Target	β-lactamase
Invitro	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].
In Vivo	A single dose of cefepime (32 mg/kg)/Taniborbactam (VNRX-5133; 16 mg/kg; s.c.) achieves >4 log10 reduction in viable bacterial counts in the neutropenic mouse lung infection model against a CTX-M-14-producing strain of K.pneumoniae[2]. 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].
