      Pranlukast is a selective cysteinyl leukotriene receptor antagonist.;Target: CYSLTR1Pranlukast has an anti-inflammatory effect on bronchial eosinophilic infiltration. Pranlukast is now widely used in the treatment of asthma. Many clinical studies have indicated that pranlukast is well tolerated and is effective in reducing bronchial hyperresponsiveness and allergen-induced bronchoconstriction. The anti-asthmatic effect of pranlukast may be rendered not only by antileukotriene activity, but also by pharmacological activity including antieosinophilic effects [1]. MedChem Express HY-B0290
      Selective CysLT1 antagonist Tocris Bioscience 3026
      Selective cysteinyl leukotriene receptor 1 (CysLT1) antagonist (IC50 values are ~ 4 - 7 and 3620 nM for CysLT1 and CysLT2 respectively). Inhibits contraction of airway smooth muscle, microvascular lea kage into airways and eosinophil infiltration. Can decrease symptoms of bronchial asthma. Tocris Bioscience 3026
