Carbazeran
Based on 1 Customer Validation
Carbazeran is a phosphodiesterase inhibitor. Carbazeran is oxidized by aldehyde oxidase/AOX1 to 4-oxo-carbazeran/hydroxycarbazeran, serving as an AOX1 probe and competitively inhibiting xanthine oxidase. Carbazeran can be used in research on congestive heart failure and chronic heart failure.

Biological Activity
Description
In Vitro
Carbazeran selectively inhibits rat kidney cytosol cyclic AMP-specific KPDE-MQ-V and KPDE-MQ-IV with Ki values of 6-8.0 μM[1].
Carbazeran weakly inhibits bovine retinal cyclic GMP-specific phosphodiesterase with a Ki of 168 μM[1].
Carbazeran is a high-affinity substrate for guinea-pig and baboon liver aldehyde oxidase (Km 0.053 and 0.009 mM, respectively) and a competitive inhibitor of bovine milk xanthine oxidase (Ki 0.015 mM), with no interaction with rabbit liver aldehyde oxidase[2].
Carbazeran inhibits isolated cyclic AMP phosphodiesterase with an IC50 of 17.5 μM[7].
Carbazeran does not demonstrably inhibit cardiac Na+,K+-ATPase activity[7].
Carbazeran increases cyclic AMP levels in rabbit right ventricular papillary muscles[7].
Carbazeran (4-20 mM extracellular K+) restores contractility in potassium-depolarized rabbit papillary muscles[7].

Solvent & Solubility
In Vitro:
DMSO : ≥ 100 mg/mL (277.46 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
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. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
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 (13.87 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 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: ≥ 5 mg/mL (13.87 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.
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.

Protocols

Research Protocol for Cardiovascular Diseases
Cardiovascular disease can be modeled as maladaptive cardiac remodeling, where ischemic injury or pressure overload activates inflammatory signaling, fibroblast activation, extracellular-matrix deposition, cardiomyocyte hypertrophy, vascular remodeling, and progressive ventricular dysfunction. The TGF-β/SMAD axis is a central profibrotic pathway after myocardial injury and pressure overload, while innate immune and cytokine pathways regulate leukocyte recruitment, scar formation, and adverse remodeling. Key unresolved questions include which inflammatory signals are reparative versus harmful, when fibrosis is protective versus maladaptive, and whether pathway inhibition improves function without weakening necessary infarct healing or compensatory remodeling.
