CI-1044 is an orally active PDE4 inhibitor with IC50s of 0.29, 0.08, 0.56, 0.09 μM for PDE4A5, PDE4B2, PDE4C2 and PDE4D3, respectively. CI-1044 selectively inhibits PDE4 crude extract from U937 cells with an IC50 value of 0.27±0.02 μM being threefold more potent than rolipram (IC50=0.91±0.14) and tenfold less potent than cilomilast (IC50=0.026±0.007) in the same assay. In the presence of PDE4 inhibitors, the production of TNF-α is dose dependently decreased with mean IC50 values from three separate experiments of 0.31±0.05, 0.26±0.05 and 0.11±0.01 μM, for CI-1044, cilomilast and rolipram, respectively[1].

Solvent & Solubility
DMSO : 100 mg/mL (251.62 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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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 (5.23 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
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 (5.23 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .

3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Blood from anesthetized rats is collected in heparin tubes, immediately distributed in 96-well microplates (250 μL/well) and incubated for 30 min at 37°C/5% CO2. Twenty-five microliters of vehicle or increasing concentrations of CI-1044, rolipram, cilomilast or solvant (saline/DMSO<0.1%) are added in wells and incubated for 30 min before the addition of LPS (100 μg/mL) or saline. Plasma is removed after a 22 to 24 h incubation at 37°C/5% CO2, transferred in another 96-well microplate and stored at ) -80°C until a TNF-α assay by ELISA[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Male rats (200 to 220 g) are used and receive either vehicle or CI-1044 orally at 0.4, 1, 4, 10 and 40 mg/kg. In the single administration experiment, all treatments are given 1 h before blood collection. In the repeated administration experiment, the treatments are given twice a day during 13 days and once on day 14, 1 h before blood sampling[1].
