Doxofylline
Based on 1 Customer Validation
Doxofylline is an orally active PDE IV inhibitor and A1AR antagonist. Doxofylline reduces inflammation in epithelial cells via inhibiting mitochondrial ROS production and amelioration of multiple cellular pathways (NLRP3-TXNIP inflammasome activation). Doxophylline can be used in studies of asthma, chronic obstructive pulmonary disease, and bronchospasm.

Biological Activity
Doxofylline (5, 10 μM; 48 h) shows potent protection against LPS-induced epithelial inflammation by reducing PGE
Doxofylline (5, 10 μM; 48 h) suppresses LPS-induced expression of NADPH oxidase subunits and TXNIP 16HBE cells[1].
Doxofylline (5, 10 μM; 48 h) inhibits LPS-induced NLRP3 inflammasome activation and secretion of IL-1b and IL-18, as well as mitigates LPS-mediated SIRT1 reduction[1].
Doxofylline (0.1-10 μM; 15 min) significantly reduces fMLP-induced leukocyte migration in BM cells (fMLP: Formyl-Methionyl-Leucyl-Phenylalanine)[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Incubation Time:48 h
-
Result:Weakened LPS-induced NO and PGE
2 in a dose-dependent manner.
Exerted dose-dependent inhibition on LPS-induced mitochondrial ROS production and NADPH oxidase subunits expression.
Suppressed LPS-induced TXNIP expression and NLRP3 inflammasome activation at the protein level in a dose-dependent manner.
Inhibited LPS-induced secretion of IL-1b and IL-18.
-
Cell Line:BM cells (from naive mice)
-
Concentration:0.1-10 µM
-
Incubation Time:15 min (pretreat)
-
Result:Notably surpressed positive migration of BM cells in response to fMLP.
Doxofylline (0.3 mg/kg; i.p.; pre-treat; single) notably reduces the adhesion of cells to the vascular tissue and surpresses the expression of LPS-induced ICAM-1 in vivo[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Male BALB/c mice (6 to 8-week-old)[2].
-
Dosage:0.3, 1 mg/kg
-
Administration:Intraperitoneal injection; single.
-
Result:Significantly inhibited the migration of neutrophils and the release of IL-6 and TNF-a into the lung lumen.
Increased the bone marrow leukocyte numbers to levels similar to those seen in the saline-treated group.
Notably reduced the number of circulating leukocytes in comparison to LPS-treated mice.
Significantly reduced accumulation of neutrophils in the peribronchial area.
-
Animal Model:Male BALB/c mice (6 to 8-week-old)[2].
-
Dosage:0.3 mg/kg
-
Administration:Intraperitoneal injection; pre-treat; single.
-
Result:Significantly reduced the adhesion of cells to the vascular tissue, but not the rolling of cells along the vessel wall in mice.
Significantly reduced the expression of ICAM-1 induced by LPS.

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 (9.39 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 (9.39 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.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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: PBS
Solubility: 65 mg/mL (244.13 mM); Clear solution; Need ultrasonic and warming and heat to 60°C
