BAY-u9773, an antagonist of cysteinyl leukotriene (Cys-LT) receptor, which have equal affinity towards CysLT1 and CysLT2 receptors. The Cys-LTs are a family of potent bioactive lipids, acting through two distinct G protein-coupled receptors named the CysLT1 and CysLT2 receptors. To determine the profile of BAY-u9773 as a Cys-LT receptor antagonist, the effect of this component on different smooth muscle preparations was investigated. The result showed that BAY u9773 antagonised 'typical' cysteinyl-leukotriene receptors and inhibited bronchial and venous muscle contractions in the human muscle preparations . BAY-u9773 was also extensively used in animal model to study the function of CysLT1 and CysLT2 receptors. For instance, BAY-u9773 treatment inhibited the infiltration of eosinophil in BAL Fluid in a model of OVA-induced airway hypersensitivity and inflammation in guinea pigs . In addition, this components was shown to act as competitive antagonist towards LTC4 and LTE4 receptors and results in contractions in trachea of guinea pig models .
