Used in research for its potential bronchodilatory effects, particularly in respiratory conditions like asthma and chronic obstructive pulmonary disease (COPD). Acts as a selective antagonist for the leukotriene D4 receptor, helping to block the action of inflammatory mediators involved in airway constriction and mucus production. Investigated for its ability to reduce bronchial hyperresponsiveness and inflammation in preclinical models. Not approved for clinical use but serves as a tool compound in studying leukotriene pathways and developing new anti-inflammatory therapies.
