WCK-4234
Based on 1 Customer Validation
WCK-4234 is a diazabicyclooctane β-lactamase inhibitor and susceptibility restorer. WCK-4234 lacks direct antibacterial activity. WCK-4234 inhibits class A, C, D β-lactamases and extended-spectrum β-lactamases to potentiate Imipenem (HY-B1369A) and Meropenem (HY-13678) activity against Gram-negative pathogens. WCK-4234 can be used for the research of gram-negative bacterial infections and β-lactamase-mediated carbapenem-resistant bacterial infections.

Biological Activity
WCK-4234 (4-8 mg/L) potently potentiates imipenem and meropenem against clinical Enterobacteriaceae isolates with KPC, OXA-48, or OXA-181 carbapenemases, or combinations of AmpC/ESBL activity and impermeability, reducing geometric mean carbapenem MICs to ≤1 mg/L, but does not potentiate carbapenems against MBL-producing Enterobacteriaceae[2].
WCK-4234 (4-8 mg/L) potentiates imipenem and meropenem against AmpC-hyperproducing, OprD-deficient, and OXA-181-producing Pseudomonas aeruginosa isolates, reducing carbapenem MIC50s by 4-fold or more, but does not potentiate carbapenems against MBL-producing Pseudomonas aeruginosa[2].
WCK-4234 (4-8 mg/L) potently potentiates imipenem and meropenem against OXA-23-producing and hyperproduced OXA-51-producing Acinetobacter baumannii isolates, reducing geometric mean carbapenem MIC50s by 8-40-fold to ≤2 mg/L in most cases, but does not potentiate carbapenems against MBL-producing Acinetobacter baumannii[2].

Solvent & Solubility
DMSO : 100 mg/mL (371.46 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
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 (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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: ≥ 2.5 mg/mL (9.29 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (9.29 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
