Nacubactam
Based on 2 publication(s) in Google Scholar
Nacubactam (OP0595 free acid) is a potent non-β-lactam-β-lactamase inhibitor with activity against class A and C β-lactamases. Nacubactam acts as a penicillin binding protein (PBP) 2-active antibacterial, and gives β-lactamase-independent potentiation of β-lactams targeting other PBPs. Nacubactam potentiates the antimicrobial activities of Piperacillin (HY-B1923), Cefepime (HY-B0692), and Meropenem (HY-13678) against CTX-M-15-positive Escherichia coli and KPC-positive Klebsiella pneumoniae.

Biological Activity
non-β-lactam-β-lactamase[1]
Nacubactam (4 μg/mL) can reduce the minimum inhibitory concentrations (MICs) of Piperacillin (HY-B1923), Cefepime (HY-B0692), and Meropenem (HY-13678) against CTX-M-15-positive Escherichia coli and KPC-positive Klebsiella pneumoniae, enhancing the antibacterial activity[1].
Nacubactam shows MICs ranging from 1 to >256 μg/mL against 11 Gram-negative isolates[2].
Nacubactam (8 μg/mL) can reduce the MIC50 of Meropenem by 8-fold, making all isolates susceptible or intermediately susceptible to Meropenem[4].
Nacubactam can inhibit Carbapenem-resistant Klebsiella pneumoniae producing KPC and restore the antibacterial activity of Meropenem[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Nacubactam (10-80 mg/kg; s.c.; administered every 8 h), when combined with Meropenem, shows the greatest in-vivo efficacy against 9 out of 10 Gram-negative isolates in a neutropenic murine complicated urinary tract infection model, reducing the bacterial load by 3 log from the 48-h control[2].

Solvent & Solubility
DMSO : 100 mg/mL (308.35 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 50 mg/mL (154.17 mM; ultrasonic and warming and heat to 60°C)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light, stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

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: ≥ 2.08 mg/mL (6.41 mM); Clear solution

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
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: ≥ 2.08 mg/mL (6.41 mM); Clear solution
