Biological Activity
β-lactamase[1]
Taniborbactam hydrochloride (VNRX-5133 hydrochloride) 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 hydrochloride (10 μg/mL) and meropenem/Taniborbactam hydrochloride 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 hydrochloride (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 hydrochloride 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].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 5 mg/mL (10.82 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 5 mg/mL (10.82 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
