MK-571 (115104-28-4) is a potent (EC50 = 1.3nM) and selective Leukotriene D4 antagonist (LTD4)1 displaying inverse agonist activity2. Blocks binding of LTD4 to human (Ki = 0.22 nM) and guinea pig (Ki = 2.1 nM) lung membranes. Selective for the CysLT1 receptor. MK-571 is also a multidrug resistance protein 1 (MRP1) inhibitor.3
