生物活性

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[1][2][3].

IC50 & Target

Adenosine A1 receptor, phosphodiesterase IV[1][2][3].

體外研究
(In Vitro)

Doxofylline (5, 10 μM; 48 h) shows potent protection against LPS-induced epithelial inflammation by reducing PGE2, NO release, and decreasing mitochondrial ROS generation in 16HBE cells[1].
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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[1]

Cell Line: 16HBE cells
Concentration: 5, 10 μM
Incubation Time: 48 h
Result: Weakened LPS-induced NO and PGE2 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 Viability Assay[2]

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.
體內(nèi)研究
(In Vivo)

Doxofylline (0.3, 1 mg/kg; i.p.; single) inhibits LPS-induced inflammation in the lungs of mice[2].
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].

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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
