Used in research for treating respiratory diseases like chronic obstructive pulmonary disease (COPD) and asthma due to its ability to block CXCR2 receptors, which play a role in neutrophil recruitment and airway inflammation. By inhibiting this pathway, it helps reduce lung inflammation and improve respiratory function in clinical studies. Also investigated for potential use in cancer therapy, particularly in combination with other agents, to modulate the tumor microenvironment by reducing immunosuppressive cell infiltration.
