SB 201146 is a potent leukotriene B4 (LTB4) receptor antagonist, exhibiting activity in the range of 10 pM to 1 μM. Its primary mechanism involves the modulation of eosinophil survival, which is a critical factor in asthma-related airway inflammation. Research indicates that SB 201146 can effectively reverse the eosinophil survival promoted by mast cells and lymphocytes, suggesting its therapeutic potential in disrupting the autocrine cysteinyl leukotriene pathway. Furthermore, this compound underscores the role of LTB4 as a paracrine mediator, influencing eosinophil dynamics in various inflammatory conditions, particularly asthma.
