体外研究(In Vitro)
Tazanolast, an orally active mast-cell-stabilizing drug, which has been shown to suppress passive cutaneous anaphylaxis, Schultz-Dale reaction in isolated tracheal muscle, and experimental asthma without antagonistic actions upon histamine- and leukotriene-D4-induced contraction, IgE-mediated or compound 48/80-induced histamine release from mast cells and lung fragments, compound 48/80-induced Ca uptake into mast cells from extracellular medium, compound 48/80-induced translocation of protein kinase C from the cytosol to the membrane fraction of mast cells, and inositol trisphosphate production without directly inhibiting phospholipase C in mast cells. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
Tazanolast administered before ozone exposure at doses of 30, 100, or 300 mg/kg inhibits ozone-induced airway hyperresponsiveness in a dose-dependent manner. Tazanolast administered after ozone exposure does not inhibit the airway hyperresponsiveness. Tazanolast does not significantly change the cell distribution of bronchoalveolar lavage (BAL) cells at 2 h after the exposure. Tazanolast significantly inhibits ozone-induced airway hyperresponsiveness in guinea pigs. has not independently confirmed the accuracy of these methods. They are for reference only.
