Used primarily as a phosphodiesterase inhibitor, this compound is involved in research related to respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). It helps relax smooth muscles in the airways by increasing intracellular levels of cyclic AMP, leading to bronchodilation. Its structure allows for interaction with enzyme targets that regulate inflammation and airway constriction, making it a focus in the development of anti-inflammatory and bronchodilator therapies. It has also been explored for potential effects on immune cell activity, contributing to its relevance in allergic and inflammatory conditions.
